SoniEx2 |
if I have x=0xF0 and y=0x0F, would x|y be faster than x+y? |
| 01:34 |
|
sfisque |
negative. modulo is one of the slowest operations a processor can do |
| 01:35 |
|
sfisque |
division is worse |
| 01:35 |
|
sfisque |
or are you talking about bitwise or/and? |
| 01:36 |
|
sfisque |
that would be faster |
| 01:36 |
|
SoniEx2 |
bitwise or and add |
| 01:36 |
|
sfisque |
that would be faster |
| 01:36 |
|
SoniEx2 |
so x|y is faster than x+y? |
| 01:36 |
|
sfisque |
yes but lossy |
| 01:36 |
|
SoniEx2 |
for x = 0xF0 and y = 0x0F |
| 01:37 |

sfisque |
for that, no loss, and it would be fine |

| 03:07 |

SoniEx2 |

| 03:07 |

SoniEx2 |
there isn't any code actually |
| 03:15 |
|
sfisque |
soniex2 - there is a sourceforge project for a java ircd - maybe take a look at that and contribute rather than building "yet another"? -- j-ircd.sourceforge.net |
| 03:16 |
|
SoniEx2 |
ok add /mode #channel +x [a:something;b:something;c:something;...;] to it |
| 03:17 |
|
SoniEx2 |
yes that's my idea |
| 03:17 |
|
sfisque |
says it's fully rfc-1459 compliant. though last update on page is 2006 so project is probably stale |
| 03:18 |
|
sfisque |
oh wow, has irc servlet container and jmx support |
| 03:18 |
|
SoniEx2 |
I don't think +x would conflict with the RFC |
| 03:19 |
|
SoniEx2 |
if so then it could be +X instead |
| 03:19 |
|
sfisque |
well, lets take a look |
| 03:21 |
|
sfisque |
x is not part of the original spec of modes. now we look at the alter rfc revisions |
| 03:22 |
|
|
cavemanlg joined ##javaee |
| 03:22 |
|
sfisque |
updated by 2810, 2811, 2812, 2813 (wow someone was a busy beaver) |
| 03:26 |
|
SoniEx2 |
does the RFC say "no extra modes"? |
| 03:26 |
|
sfisque |
generally rfc's won't specify things like that. they generally indicate "minimal functionality" |
| 03:27 |
|
SoniEx2 |
so there's nothing wrong with adding chanmode +x |
| 03:28 |
|
sfisque |
nothing at all.. it would seem from 2812 -> The available modes are as follows: |
| 03:28 |
|
sfisque |
a - user is flagged as away; |
| 03:28 |
|
sfisque |
i - marks a users as invisible; |
| 03:28 |
|
sfisque |
w - user receives wallops; |
| 03:28 |
|
sfisque |
r - restricted user connection; |
| 03:28 |
|
sfisque |
o - operator flag; |
| 03:28 |
|
sfisque |
O - local operator flag; |
| 03:28 |
|
sfisque |
s - marks a user for receipt of server notices. |
| 03:28 |
|
sfisque |
Additional modes may be available later on. |
| 03:31 |
|
sfisque |
so it looks like +/-x is open for expansion :-) |
| 03:31 |
|
sfisque |
2813 makes no mention of any "new" user modes, so i think you're safe implementing an "x" mode |
| 03:33 |

SoniEx2: think about what you've just asked. you've linked a project and said "it doesn't work" - are you able to provide an error message of some description, and maybe describe the environment in which you are executing the code |
| 04:43 |
|
SoniEx2 |
there's no error |
| 04:44 |
|
grug |
mmk well then think even harder about how you can aid us in helping you |
| 04:44 |
|
SoniEx2 |
but it sets all the layer names and volumes to the default ("null" and 100%) |

can you provide a self contained test case for us? |

| 13:50 |

Quest |
Naros, Iam fine :) |
| 13:50 |
|
Quest |
where should the messages file (for internationalization ) be put and images/ css/ script files be put in an mvc application? |
| 13:50 |
|
Quest |
I mean whats the good practices |
| 13:54 |
|
Naros |
I've seen varying approaches. |
| 13:54 |
|
Quest |
whats yours |
| 13:55 |
|
Naros |
Well, in a struts2 world, i18n stuff is a bit different. Generally, they go in |
| 13:55 |
|
Naros |
src/main/resources/<package folder>/<struts2actionname>.properties |
| 13:55 |
|
Naros |
But one can override that and specify global i18n files like other frameworks |
| 13:55 |
|
Naros |
In which case I typically put them in src/main/resources |
| 13:56 |
|
Naros |
which translates to WEB-INF/classes during the build process. |
| 13:57 |
|
Naros |
As for images/css/static stuff |
| 13:58 |
|
Quest |
cant i just put images/ scripts in web-inf/views/jsps/images and scripts in web-inf/views/jsps/scripts of scripts |
| 13:58 |
|
Naros |
generally that goes under src/main/webapp/static or whatever directory structure you want. |
| 13:58 |
|
Quest |
and scripts in web-inf/messages.properties for messages. |
| 13:58 |
|
Naros |
No public content should never be put in WEB-INF because you can't serve it back to the clients |
| 13:59 |
|
Naros |
src/main/webapp/images or src/main/webapp/static/images |
| 13:59 |
|
sfisque |
depends. if you want to force them through the servlet conduits, you don't want stuff at the root of the war |
| 13:59 |
|
Naros |
I generally prefer the static approach with sub directories for images, css, js, etc. |
| 13:59 |
|
sfisque |
aka, prevent "directory surfing" |
| 14:00 |
|
Naros |
Aye, but that implies he sets up filters so that .js, .png, .gif, etc are all served back through some servlet filter. |
| 14:00 |
|
Naros |
which I disagree with for that sorta stuff |
| 14:00 |
|
Quest |
hm |
| 14:01 |
|
Naros |
In particular, it often introduces bad habits in .JS files as I've seen developers put struts tags, etc inside .JS files and have the struts filter wire in stuff that really is bad habits |
| 14:02 |
|
sfisque |
the overhead isnt that much for simple pass through. those resources are already going through the servlet engine anyway (it has to serve them up to whatever proxy is fronting the container) |
| 14:02 |
|
sfisque |
and most frameworks have a "default" servlet for that purposes |
| 14:03 |
|
|
pallu joined ##javaee |
| 14:03 |
|
sfisque |
if those bits are "that static" (aka glacial) they could be moved out of the war and put onto a centralized consumption endpoint |
| 14:03 |
|
Quest |
rephrase: i meant , cant i just put images, scripts in webapps/web-inf/views/jsps/images and scripts in webapp/web-inf/views/jsps/scripts and messages in webapps/web-inf/messages.properties |
| 14:04 |
|
Naros |
I prefer message.properties in src/main/resources |
| 14:04 |
|
Naros |
I prefer all .properties in my classes directory at the top of my classpath. |
| 14:04 |
|
Quest |
hm. why put in resource dir? |
| 14:04 |
|
sfisque |
you "can" put them anywhere in the war. whether they are "trivially" accessible is a different matter |
| 14:05 |
|
Naros |
WEB-INF/classes is naturally in your classpath for your app. |
| 14:06 |
|
sfisque |
general practice though is if they need to be protected, somewhere in web-inf works fine. if it needs to be on your classpath (as naros points out) web-inf/classes and web-inf/lib work nicely |
| 14:07 |
|
sfisque |
if the artifacts are "public" access, you can distribute them at the root of your war or in subdirs rooted there. |
| 14:07 |
|
Naros |
But you can put images/scripts under WEB-INF, but I wouldn't put them under JSPs. Images may also be used for things such as PDFs or other non-JSP rendered content depending on the application. |
| 14:07 |
|
Quest |
I woudlnt want the properties file to be access to public. and would like the servlets only accesing the images |
| 14:08 |
|
Naros |
WEB-INF/views/images | WEB-INF/views/js | WEB-INF/classes/messages.properties |
| 14:08 |
|
Naros |
that would be my preference |
| 14:08 |
|
Quest |
ok |
| 14:09 |
|
Naros |
But there is an advantage of deploying static content separately |
| 14:09 |
|
Naros |
You could put js / images / css on an apache httpd server and allow the servlet container to handle the servlet only aspects of the app. |
| 14:10 |
|
Naros |
reduces the load on the servlet container for static content |
| 14:10 |
|
Naros |
if it is truly public static content |
| 14:12 |
|
Quest |
I wanted a way that in future if i want to change paths and file locations, i dont have to refactor all the jsps or .java classesI woudlnt want the properties file to be access to public. and would like the servlets only accesing the images |
| 14:13 |
|
Quest |
i18n is a way to reach /resources or anything in /classes ? by a jsp? |
| 14:13 |
|
Naros |
in struts world we have a TextProvider and a s:text tag to handle that stuff. idk about spring-mvc. |
| 14:13 |
|
sfisque |
it has similar mechs |
| 14:14 |
|
Naros |
I don't understand how refactoring jsps affects images. |
| 14:14 |
|
sfisque |
if he's using relative paths, and the path structure changes |
| 14:15 |
|
Naros |
Aye, but how often do image paths change if the images are stored outside whatever structure the jsps use? |
| 14:15 |
|
sfisque |
or similarly for explicit paths also but that's more easily sovled with a tool |
| 14:15 |
|
sfisque |
i think he was talking about when they're stored internal |
| 14:15 |
|
Naros |
Aye, Search-And-Replace :P |
| 14:16 |
|
Quest |
Naros, if i change images dir path. all jsps pointing to that previous path would have to be changed |
| 14:16 |
|
sfisque |
unless you use a #{var} |
| 14:16 |
|
sfisque |
to point to where the images are located |
| 14:16 |
|
sfisque |
then you change it once |
| 14:16 |
|
sfisque |
or a couple times if you have "n" referneces to subdirs , etc. |
| 14:16 |
|
Quest |
sfisque, exactly |
| 14:17 |
|
Naros |
Aye just jsp include a parameter file at the top of your jsps |
| 14:17 |
|
Quest |
that was my plan. to use <spring:message code="paths.imagedir"/> |
| 14:18 |
|
Naros |
We had some similar needs beyond just JSP paths so we have a table in the DB for each instance that has some configurable parameters that the context loads during startup. When we change attributes in this table, an event fires that reloads the context params on the fly. |
| 14:18 |
|
sfisque |
meh, don't use i18n to do heavy lifting. it's for internationalization, not variable storage |
| 14:19 |
|
Quest |
sfisque, hm. but advantage can be taken out of its approach. anyways. what do you suggest. I want all to be generic and easy to refactor |
| 14:19 |
|
Quest |
Naros, ^ |
| 14:20 |
|
sfisque |
spring (and any other web framework) has a very simple mech for expanding a variable in context. #{} (or ${} for legacy frameworks) |
| 14:20 |
|
Quest |
hm |
| 14:20 |
|
Quest |
Naros, what did you meant by include a parameter file at the top of your jsps |
| 14:25 |
|
Naros |
You create a JSP that defines some page context values |
| 14:25 |
|
Naros |
such as what your path is to your images |
| 14:25 |
|
Naros |
You include that jsp inside all your others so if those parameters need to change, you change 1 JSP and all the others will behave right |
| 14:26 |
|
Naros |
in the struts world I can do <s:include value="/WEB-INF/view/global-parameters.jsp" /> |
| 14:26 |
|
Naros |
it basically takes that JSP content and puts it where the include tag is |
| 14:26 |
|
Naros |
I think JSP has <jsp:include /> or something |
| 14:27 |
|
Quest |
oh |
| 14:28 |
|
Quest |
how to set up the params in that global-parameres.jsp and how to print out those in the jsp pages in which they are included. for e.g for <img src="<what here?>pic.jpg" |
| 14:29 |
|
Naros |
if you use the core jstl taglib, you can use c:set to set a variable in the pageContext |
| 14:30 |
|
Naros |
<c:set var="imagePath">/WEB-INF/view/images</c:set> |
| 14:30 |
|
Quest |
oh. that was a thing i never used before. thought its default jstl |
| 14:30 |
|
Quest |
hm |
| 14:30 |
|
Naros |
But I'm surprised that spring-mvc doesn't have a URI tag :P |
| 14:30 |
|
Quest |
if it did. i wont be aware of it. |

:) |
| 14:31 |
|
Naros |
<img src="<s:url value="/WEB-INF/view/images/logo.gif" />" /> |
| 14:31 |
|
Quest |
c:set for setting and c:what for output? |
| 14:31 |
|
Naros |
Struts has one :P |
| 14:31 |
|
Naros |
but in the struts world, I can't put that sorta stuff in WEB-INF using that tag that way :E |
| 14:31 |

hehe, as a dev being in irc is commonplace i thought :E |
| 14:34 |
|
sfisque |
do we know if he's actually a dev "by day"? |
| 14:35 |
|
Naros |
I do not. |
| 14:35 |
|
sfisque |
for all "i" know, he's a hobbiest |
| 14:35 |
|
sfisque |
and he might be working as a call center jockey |
| 14:35 |
|
Naros |
perhaps |
| 14:37 |
|
sfisque |
or he might be a bell labs post doc, and he's just doing this to amuse himself in a perverse way :P |

So I have this attribute that when a user selects a specific value, I need to populate a list of things. But this list could be considerably deep, thousands depending on the volume. Putting thousands of values in a combo-box is terribly bad practice. |
| 14:37 |
|
sfisque |
aye |
| 14:38 |
|
Naros |
I'm just not sure of any particular other approach |
| 14:38 |
|
sfisque |
can you use an "auto-complete" instead? force the user to type a few chars and then filter the list down to a useable size? |
| 14:39 |
|
sfisque |
could also go the "sublaunch a chooser dialog" that offers filtering options |
| 14:39 |
|
Naros |
Aye, was thinking the filter route. |
| 14:39 |
|
sfisque |
or use a separate view, with filtering that then dispatches to the "next" step in the workflow |
| 14:39 |
|
sfisque |

It's when they select a vendor, I need to allow them to select a PO based on the selected vendor to associate the repair document against. |
| 14:40 |
|
Naros |
aye, they dislike the workflow approach, which makes no sense to me. |
| 14:40 |
|
Naros |
Workflow would fit this to a tee. |
| 14:40 |
|
Naros |
Step1 through Step5, with a review/jump to modify concept. |
| 14:40 |
|
sfisque |
and it's an established paradigm. tell them it's a "shopping cart" and sell it that way :P |
| 14:41 |
|
Naros |
hehe, agreed. |
| 14:41 |
|
sfisque |
we'll use the "e commerce" paradigm to get better buy-in from our upstream and downstream presence based user experience context..... |
| 14:41 |
|
Naros |
thing is once the data is captured, they can come back and modify it at any point. |
| 14:41 |
|
sfisque |
smells like shopping cart to me |
| 14:42 |
|
Naros |
hehe, it would make the UI look better rather than what it currently is. |
| 14:42 |
|
Naros |
30+ fields on a single screen isn't a great user experience. |
| 14:42 |
|
sfisque |
it's funny how just about every enterprise project i've been on for the last 15 years generally boils down the the same concept... e-commerce with a shopping cart |
| 14:43 |
|
* sfisque |
agrees with naros |
| 14:43 |
|
sfisque |
but but but, it works just like our old green screens |
| 14:43 |
|
Naros |
pretty much. our entire app is built on search & do a business process. |
| 14:44 |
|
sfisque |
and the vast majority of BPs are just "choose items" (resource) and walk them through some queue (checkout) |
| 14:44 |
|
Naros |
BW analyzes the business data, generates analytics and I present those in pretty clickable, drilldown charts |
| 14:45 |
|
Naros |
but yah, there are very much similarities in almost every webapp |

it isn't easy to make your domain model not have cyclic dependencies :E |
| 15:08 |
|
Naros |
*it is |
| 15:08 |
|
Naros |
er no, isn't |
| 15:08 |
|
Naros |
lol |
| 15:09 |
|
Naros |
We have a particular business process which has a domain model. But User seems to have that domain model as a property and core shouldn't reference this other module. |
| 15:09 |
|
Naros |
>.< |
| 15:10 |
|
sfisque |
does the circularity exist in the schema (via FK relationships)? |
| 15:11 |
|
Naros |
Yes. |
| 15:11 |
|
Naros |
Only cause it was coded such way. |
| 15:11 |
|
sfisque |
gotcha |
| 15:12 |
|
Naros |
Could move the relationship to be managed by that other module rather than on the user object itself is one way. |
| 15:12 |
|
Naros |
take this code_id and create a separate table managed by that process that relates their code_id to a user_id |
| 15:13 |
|
Naros |
And during the save of user, update user, and create this relationship as a part of the business process within the same trx. |
| 15:13 |
|
Naros |
but still feels kludgy. |
| 15:21 |
|
sfisque |
either way you have an FK relationship. either have to figure out a way to reorder the linkages to remove the circularity or accept it as part of the model |

sfisque: alternative to the circular dependency was to change the business process. |
| 17:38 |
|
Naros |
when defining business codes, associate those to users. |
| 17:38 |
|
Naros |
rather than allowing the definition of a user to tie back into a business code |
| 17:39 |
|
Naros |
it means changing the schema but makes more logical senses in flow for users too. |

agrees with naros |
| 18:22 |
|
Naros |
But in some areas, at least it's slowing down a bit |
| 18:23 |
|
sfisque |
dunno about that. i've read that java10 or thereabouts we'll see the "end" of primitives. no more autoboxing, and such |
| 18:23 |
|
sfisque |
that will be quite a migration |
| 18:23 |
|

aye, heard the same. |
| 18:23 |

It isn't that far if you think about it pdurbin. |

Wasn't so long ago we were at java 2 :P |

has anyone played with the new "closures" feature? i've read a little and looked at it during the early phases. thoughts? |

true... but.. it's available |

Aye thru OpenJDK |
| 18:26 |
|
Naros |
I particularly love closures and can't wait for them. |
| 18:26 |
|
Naros |
Use them in jQuery scripting all the time |
| 18:26 |
|
sfisque |
what will they solve for you? i'm not sure i'm a fan. i can see the advantage in highly parallel frameworks, but i only foresee lots of "abuse", sort of like when inner classes debuted |
| 18:29 |
|
pdurbin |
sfisque: I listened to these JavaOne 2012 talks about lambdas and they're good: https://oracleus.activeevents.com/connect/sessionDetail.ww?SESSION_ID=5089 and https://oracleus.activeevents.com/connect/sessionDetail.ww?SESSION_ID=4862 |
| 18:31 |
|
Naros |
Just like everything else, they'll have their uses in various cases or ways to short-cut other means to achieve the same result. |
| 18:31 |
|
Naros |
One immediate use is rather than defining interfaces and then implementations for certain constructs, you can get by passing a closure instead and doing the very samething. |
| 18:32 |
|
Naros |
While crude, Comparing objects come to mind. |
| 18:33 |
|
Naros |
But it does blur lines and certain can be abused. |
| 18:33 |
|
Naros |
ie: pass a function into my service tier to lookup some i18n text from my web tier's i18n resource class. |
| 18:33 |
|
sfisque |
aye. i see them as a possible "delegate" shorthand. but i also see that as an abusable construct (aka you get a ton of anonymous runtime constructs that can make debugging spurious state issues difficult) |
| 18:34 |
|
Naros |
the closure would be in my web tier's controller by definition and thus iirc, the server tier wouldn't import any of my web tier objects as a result. |
| 18:34 |
|
sfisque |
the real question is, will we see Functions as a top level object so we can finally do away with "utility classes" |
| 18:34 |
|
Naros |
I'd love to, as I dislike these Util classes |
| 18:35 |
|
Naros |
I love using std::bind or boost::bind in C++ to pass functions to other things |
| 18:35 |
|
Naros |
but can quickly lead to spaghetti code |
| 18:35 |
|
sfisque |
aye giving java the concept of "vector tables" can be both nice and daunting |
| 18:36 |
|
Naros |
vtables - ugh |
| 18:36 |
|
sfisque |
that is one thing i miss from C/C++, the ability to build a map of *function() that can be bound at runtime for dynamic dispatching |
| 18:37 |
|
Naros |
Precisely. My game engine makes heavy use of that for the message dispatch framework for both async and sync callbacks. |
| 18:37 |
|
sfisque |
also allow for "looser" coupling for plugin and strategy patterns |
| 18:37 |
|
Naros |
It's just another flavor of the Observer pattern in the end, but with far less coupling of components. But maintenance is far higher long-term |
| 18:38 |
|
Naros |
lol exactly. |
| 18:39 |
|
Naros |
It'll probably be heavily leveraged in frameworks and probably very little in other avenues to start. |
| 18:40 |
|
Naros |
Java's use of the singleton pattern drives me bonkers |
| 18:40 |
|
sfisque |
do you mean "in java" or by java devs? |
| 18:40 |
|
Naros |
So heavily frowned upon in other languages lol. |
| 18:40 |
|
Naros |
by java devs mostly. |
| 18:41 |
|
Naros |
it's pretty commonplace in java code to see singletons |
| 18:41 |
|
sfisque |
well, without a first class function entity, what other facility do you have? |
| 18:41 |
|
sfisque |
it's either that or a util class with all static public methods |
| 18:41 |
|
Naros |
but in java, management of the allocation/resources that come with singletons isn't a nightmare as it is in say C++ |
| 18:42 |
|
Naros |
Since heap is managed by the underlining language and not the developer. |
| 18:42 |
|
sfisque |
at some point, for memory scalability you need the ability to just leverage defining a method/function once and dispatching through it |
| 18:42 |
|
sfisque |
aye |
| 18:42 |
|
sfisque |
C/C++ memory management is .... "fun"? |
| 18:42 |
|
Naros |
that's one of many ways to describe it. |

I don't understand why I can't catch the EJBException exception in this getStudyByGlobalId method: https://github.com/IQSS/dvn/blob/00cbd45497b9e73a17bb6f20e2c7e5cf116995bf/src/DVN-EJB/src/java/edu/harvard/iq/dvn/core/study/StudyServiceBean.java#L1492 |
| 19:17 |

this is where I'm trying to catch it: https://github.com/IQSS/dvn/blob/00cbd45497b9e73a17bb6f20e2c7e5cf116995bf/src/DVN-web/src/edu/harvard/iq/dvn/api/datadeposit/UrlManager.java#L173 |
| 19:19 |
|
sfisque |
which throw is not being caught? |
| 19:20 |
|
pdurbin |
sfisque: the ':' not found in string one: https://github.com/IQSS/dvn/blob/00cbd45497b9e73a17bb6f20e2c7e5cf116995bf/src/DVN-EJB/src/java/edu/harvard/iq/dvn/core/study/StudyServiceBean.java#L1500 |
| 19:21 |
|
sfisque |
since EJBException is a RuntimeException is the container is trapping it? |
| 19:21 |
|
pdurbin |
hmm |
| 19:22 |
|
sfisque |
generally RuntimeExceptions indicate something "very bad" but not as bad as Error happened |
| 19:22 |
|
sfisque |
"mostly bad" :P |

| 19:26 |

| 19:26 |
|
pdurbin |
I *am* able to catch the exception |
| 19:27 |
|
sfisque |
ok |
| 19:27 |
|
pdurbin |
but what surprises me is that the stacktrack is printed to server.log (glassfish) anyway |
| 19:27 |
|
sfisque |
EJBException is probably registered with the container's logger |
| 19:27 |
|
pdurbin |
stacktrack!? stacktrace. can you tell I'm almost out the door? ;) |
| 19:27 |
|
sfisque |
so that if you are not catching it, it's still logged |
| 19:28 |
|
pdurbin |
hmmm |
| 19:28 |
|
pdurbin |
not sure where to look for that |
| 19:28 |
|
sfisque |
otherwise EJBEx's would fail quietly |
| 19:28 |
|
sfisque |
which would be VERY BAD |
| 19:29 |
|
sfisque |
i would guess the container has an interceptor on EJBException constructors or somesuch so that they do not go "unnoticed" |

| 20:57 |
|

both netbeans and eclipse |
| 20:58 |

Naros |
We found that MyEclipse had slow auto-complete if you had lots of capabilities enabled, particularly JPA. One of our solutions was to split the project into multiple jars. |
| 20:58 |
|
onr |
compared to IDEA |
| 20:59 |
|
Naros |
when working within each project, its as fast as any other IDE I've worked with. |
| 20:59 |
|
Naros |
but speaking of auto-complete. I noticed something strange with AC and AspectJ. |
| 21:00 |
|
Naros |
If I want to weave an aspect into a class in JAR-A but want to use JAR-A in WAR-B, for whatever reason WAR-B wants AspectJ capabilities. |
| 21:00 |
|
Naros |
that doesn't make sense to me. |
| 21:01 |
|
Naros |
Otherwise AC doesn't see the weaved content. |

calendar would work totally fine. just set the Y/M/D to some static value and just use the H:M:S:ms fields |
| 21:47 |
|
sfisque |
and couple with a SimpleDateFOrmat object to format the output to what you want |

but calendar is for dates... |
| 21:49 |
|
sfisque |
Calendar is for time, regardless of granularity |
| 21:49 |
|
sfisque |
and it couples with DateFormat natively |
| 21:51 |
|
sfisque |
create a wrapper that instantiates the Calendar from the factory method and attaches a SimpleDateFormat configured the way you want it |
| 21:52 |
|
sfisque |
you can proxy the methods that you want exposed and hide the methods you want hidden (day, month, year, etc.) |

so no files in /resources ? |
| 22:08 |
|
Naros |
src/main/resources points to /WEB-INF/classes during a maven build. |
| 22:09 |
|
Quest |
oh |
| 22:09 |
|

so only messages would be in resources |
| 22:10 |
|

Chances are that won't be the only thing in there. |
| 22:10 |

Naros: hmm |
| 22:10 |

That is where log4j.xml, struts.xml, and all my applicationContext-*.xml files reside. |

Usually I put anything that my java source code may need in /src/main/resources. |
| 22:11 |
|
Naros |
Usually all that ends up in /src/main/webapp is web.xml and any view related artifacts. |

My IDE shows Maven projects differently than yours. |
| 22:16 |
|
Quest |
hm |
| 22:16 |
|
Quest |
your using which ide? |
| 22:17 |
|
Naros |
mine just makes a distinction between the following |
| 22:17 |
|
Naros |
"/src/main/java" |
| 22:17 |
|
Naros |
"/src/main/resources" |
| 22:17 |
|
Naros |
"/src/test/java" |
| 22:17 |
|
Naros |
"/src/test/resources" |
| 22:17 |
|
Naros |
"/src/main/webapp" |
| 22:17 |
|
Naros |
they are all nodes off the project root. |
| 22:17 |
|
Quest |
same here. java and resources and webapps are both in main |
| 22:18 |
|
Quest |
I just made a dir in between named as web |
| 22:18 |
|
Quest |
its the same as your ides |

Maybe that might be more helpful to understand what I meant. |

In the end, maven moves things based on directories, regardless how the IDE renders it. |

neat little gotcha. example of how "everything in java is a pointer". i had a controller holding a List which was displaying in a primefaces table. when loading the page, i was setting the attribute to a new arraylist with data from a different collection and the PF table was still holding the old arraylist until it got an event to refresh. so i'd leave and come back in, and get old list, until some ajax fired and it asked for the array list again via t |
| 23:10 |
|

unsurprising once i figured it out, but definitely annoying to track down |

sometimes i wish object references were more "durable", like "if i reset this variable, i want all references to it to accept that change" |
| 23:18 |
|
sfisque |
rather than everything is just a pointer |
| 23:18 |

Quest |
I have resources dir in my src.main. but in my war file it only lists the contents of resources in the src.main and resources dir dont even exist. why |
| 23:26 |
|
whartung |
lots of time the resrouces dir is simply copied in to the WEB-INF/classes folder |
| 23:26 |
|
whartung |
since most folks want resrouces on their class path, and that's the place to do that |
| 23:28 |
|
Quest |
yes. thats what happened. its in webinf/classes/files but not in webinf/classes/resources/files |
| 23:29 |
|
whartung |
no, it wouldn't be |
| 23:29 |
|
whartung |
if you want that, put it in resources/resource/file.txt |
