postgresql vs oracle , if you stuck with postgres your doomed |
| 01:23 |
|
jayz |
and there are no tuts like in Oracle other then docs :/ |
| 01:25 |
|
jayz |
well hehe shouted in there channel :) |
| 01:28 |
|
sfisque |
postgresql has some nice features, but it is a bit "byzantine" in how if functions. |
| 01:28 |
|
jayz |
sfisque: its not like sqlite or oracle , there is no tut other then docs |
| 01:29 |
|
jayz |
and if you got stuck its all hell |
| 01:31 |
|
jayz |
its hell for beginners actually |
| 01:33 |
|
sfisque |
postgresql is unlike ANY db i've ever used (and i've used quite a few) |
| 01:33 |
|
jayz |
your right its unlike any db :D |
| 01:34 |
|
sfisque |
i'm not a big fan of it, BUT it does have some nifty "native types" like ip address, which is handy if you need to are doing NMS work and needs canonical sorting and comparison functions to work properly |

thank god i did sqlite first or else might have gone mad , postgres is not for beginners ,,,, Its never for beginners |
| 01:39 |
|
sfisque |
i would posit it's not for the sane, regardless of skill level |

also, postgres is good for spatial data (GIS stuff) |
| 13:50 |

I must admit that I find mysql easier but I think postgres is good for me to get more familiar with |

hi |
| 16:12 |
|
Guest20878 |
I have made a valid form but cannot get the form values by spring controller. it says some syntactic error or value not set. http://pastie.org/8498621 any help? |
| 16:12 |
|
Guest20878 |
spring^ |
| 16:14 |
|
sess |
Guest20878: what url are you posting to |
| 16:14 |
|
sess |
exactly |
| 16:14 |
|
sess |
for that to work you need ?taskId=123 |
| 16:14 |
|
sess |
since you are requesting a RequestParam |
| 16:14 |
|
sess |
a multipartFile can definetly not be sent in the query string |
| 16:14 |
|
Guest20878 |
i need to send data by POST |
| 16:15 |
|
sess |
@RequestPAram is not the correct annotation |
| 16:15 |
|
Guest20878 |
the file and the taskId . boh |
| 16:15 |
|
Guest20878 |
sess, oh. |
| 16:15 |
|
Guest20878 |
then what is correct?4 |
| 16:15 |
|
sess |
thats for.. request parameter, not a big suprise |
| 16:15 |
|
sess |
http://docs.spring.io/spring/docs/3.2.x/spring-framework-reference/html/mvc.html |
| 16:15 |
|
sess |
read it |
| 16:16 |
|
Guest20878 |
k |
| 16:17 |
|
sess |
or actually @RequestParam might work for taskId |
| 16:17 |
|
sess |
you should make a form object |
| 16:17 |
|
sess |
http://www.beingjavaguys.com/2013/08/spring-mvc-file-upload-example.html |
| 16:18 |
|
Guest20878 |
making a form object is not compulsory |
| 16:18 |
|
Guest20878 |
do you mean @RequestParam will work for taskId |
| 16:20 |
|
sess |
i saw examples of people using it |
| 16:21 |
|
Guest20878 |
how can I bypass making form classes? |
| 16:21 |
|
sess |
Guest20878: just to check also.. was your posted taskId null perhaps? |
| 16:21 |
|
sess |
by default requestParam is required, i.e not null allowed |
| 16:21 |
|
Guest20878 |
no. |
| 16:22 |
|
sess |
try it out without the multipart file and see if just taskid works |
| 16:22 |
|
Guest20878 |
the task id is hardcoded |
| 16:22 |
|
Guest20878 |
k |
| 16:22 |
|
sess |
hardcoded? |
| 16:22 |
|
Guest20878 |
value="abc" |
| 16:22 |
|
Guest20878 |
like this^ |
| 16:22 |
|
sess |
ah |
| 16:23 |
|
sess |
ah i think i know your problem |

http://stackoverflow.com/questions/17964841/how-to-get-param-in-method-post-spring-mvc |
| 16:23 |

sess |
eny multipart/form-data ruins it |
| 16:23 |
|
sess |
you need a multipartResolver in your spring conf |
| 16:24 |
|
Guest20878 |
hm |
| 16:26 |
|
Guest20878 |
HTTP Status 500 - Request processing failed; nested exception is java.lang.IllegalArgumentException: Expected MultipartHttpServletRequest: is a MultipartResolver configured? |

Guest20878 |
haha |

Guest20878 |
ok. thanks nice. |

hi Quest san |
| 19:03 |
|
neuro_sys |
cem are you turkish? |
| 19:03 |
|
neuro_sys |
your name is |
| 19:04 |
|
neuro_sys |
piqued my interest |
| 19:38 |
|
neuro_sys |
what tool do you use, if any, to create db tables from java beans? |
| 19:42 |
|
sess |
i prefer the other way around |
| 19:42 |
|
sess |
jpa can do it otherwise |
| 19:48 |
|
neuro_sys |
for other way around I use hibernate reverse engineering in eclipse, you? |
| 19:48 |
|
sajjadg |
JPA is not a perfect solution. I had lots of problem with it. I always design the table and then have to change it to be compatible with JPA. haven't tried designing Entities and let the JPA provider create the db...maybe in this case I encounter less bugs |
| 19:48 |
|
sajjadg |
I used hibernate and eclipselink to create entity from db but not the reverse |
| 19:49 |
|
neuro_sys |
(I'm just starting a new project, excuse the random questions) |
| 19:50 |
|
sajjadg |
I had problem with DB enum, default value and some data types before...I just try to ignore them when I'm creating the tables |
| 19:50 |
|
neuro_sys |
do you all use maven by default? for instance in my company, I couldn't get my team members to use it, for they think it's overkill for our self contained relatively small projects. |
| 19:50 |
|
sess |
maven is the best for small projects |
| 19:50 |
|
sajjadg |
maven is great. |
| 19:50 |
|
sess |
i even use it for projects < 10 classes |
| 19:51 |
|
sess |
only situation I wouldnt use it would be if the project had 0 dependencies |
| 19:51 |
|
neuro_sys |
did you ever have to convert an existing project into maven, rather than starting it with maven in the beginning? |
| 19:51 |
|
sajjadg |
neuro_sys, they don't have to deal with it most of the time. you just set it up and they can enjoy it |
| 19:52 |
|
sess |
neuro_sys: not yet, but im planning to convert an ant project as soon as the custom wants to pay for it |
| 19:52 |
|
sajjadg |
neuro_sys, yeah. I did. not that hard. |
| 19:52 |
|
sess |
the closer to standard the ant targets are, the easier it is |
| 19:53 |
|
sess |
the hardest parts lies in finding out the exact versions of all libraries (good thing to do anyways), and if you have any jars that are not available in repositories thats a bitch too |
| 19:53 |
|
neuro_sys |
I did one too, maven compile outputs all the missing classes anyway, and looked each of them up in the maven central, and copy pasted pom dependency snippets |
| 19:53 |
|
sess |
if the ant tasks are straight forward and you know the dependencies, ant to maven conversion should be doable in a few hours tops |
| 19:53 |
|
sajjadg |
sess, I once tried ant/ivy instead of maven and I regretted it and changed to maven. |
| 19:53 |
|
cem_ |
maven example please |
| 19:53 |
|
cem_ |
simple one |
| 19:53 |
|
sess |
google |
| 19:53 |
|
neuro_sys |
but we have some peculiar jars, so I had to install them to my local maven repository. |
| 19:54 |
|
sajjadg |
I don't know about gradle yet but maven is the best thing around in that field |
| 19:54 |
|
neuro_sys |
so to get them to use maven, I'd have to set up a remote maven repository |
| 19:54 |
|
cem_ |
javaeebot: lucky maven |
| 19:54 |
|
sess |
neuro_sys: yeah that sucks |
| 19:54 |

| 19:54 |
|
sess |
this one is better |
| 19:54 |
|
sess |
for a minimal example |
| 19:55 |
|
sess |
you basicly set the project name and define the dependencies, and youre ready to go |
| 19:55 |
|
neuro_sys |
do you guys ever have to use web sockets? seems java ee 7 has a spec for it, although doesn't seem to be in widespread use currently. |
| 19:55 |
|
sess |
neuro_sys: you dont _need_ a remote repository though |
| 19:55 |
|
sess |
ive been pondering using the ant plugin to install a checked in jar if it does not exist in local repository |
| 19:55 |
|
neuro_sys |
sess: but for those jars, all the other team members would have to install the jars into their local maven repo |
| 19:55 |
|
sess |
scriptable |
| 19:56 |
|
neuro_sys |
oh well yes |
| 19:56 |
|
sess |
check in jars into vc |
| 19:56 |
|
neuro_sys |
unfortunately they don't like to use command line much as much as I do |
| 19:56 |
|
sess |
though having a repository would be awesome if you use a lot of jars that change often |
| 19:56 |
|
sajjadg |
neuro_sys, I had a job offer for that...I didn't accepted it. |
| 19:56 |
|
sess |
thats why you check in scripts so they dont have to :) |
| 19:56 |
|
neuro_sys |
sajjadg: for what, websockets? |
| 19:56 |
|
sajjadg |
yeah |
| 19:56 |
|
sess |
neuro_sys: it's interesting, but usage is pretty limited |
| 19:57 |
|
sess |
chat applications is the default example |
| 19:57 |
|
sess |
it seems blazing fast though |
| 19:57 |
|
neuro_sys |
I just used one, initially with the standard JSR-356, although it's only available in tomcat 8, for which eclipse doesn't have an adapter plugin |
| 19:57 |
|
sajjadg |
archtypes are cool :) |
| 19:57 |
|
neuro_sys |
so I converted to https://github.com/TooTallNate/Java-WebSocket |
| 19:57 |
|
sajjadg |
man...eclipse is not doing good lately |
| 19:58 |
|
sajjadg |
I remember the time when everyone said eclipse is best...but now that I use it I don't see it! |
| 19:58 |
|
neuro_sys |
I needed to use websockets for using some currency exchange services out there |
| 19:58 |
|
sess |
never liked eclipse, such cluttery ui |
| 19:58 |
|
sess |
IDEA is a favorite |
| 19:59 |
|
neuro_sys |
I should better switch to IDEA |
| 19:59 |

IDEA is not free for JEE and I can't buy it. |
| 19:59 |
|
whartung |
I'm a netbeans guy, never cared for eclipse |
| 20:00 |
|
sajjadg |
I installed IDEA for android dev (android studio) and I didn't like it! maybe I need to force myself to work with it for sometime |
| 20:00 |

emacs just isn't keeping up with the Java IDEs |

I'm enjoying vim but it doesn't support RTL! |
| 20:02 |
|
neuro_sys |
what's RTL? |
| 20:02 |
|
sajjadg |
I am disappointed |
| 20:02 |
|
sajjadg |

I'm sorry |

neuro_sys |
haha yeah |
| 20:02 |

it supports Unicode but not RTL |
| 20:03 |
|
sfisque |
does ncurses even support rtl |
| 20:03 |
|
sfisque |
? |
| 20:03 |
|
neuro_sys |
is that because your native language is RTL? |
| 20:03 |
|
sajjadg |
yeah. |
| 20:03 |
|
* cem_ |
looking ($ $) just seeing which is easy ant or maven |
| 20:03 |
|
neuro_sys |
switch to a more sensible language |
| 20:03 |

whartung |
emacs can't RTL? |
| 20:03 |
|
sajjadg |
I don't use it that much. but when I want to write something in my lang. oh man... |

neuro_sys, :) |
| 20:04 |
|
neuro_sys |
uh, it feels such a chore to set up hibernate for the project now |
| 20:05 |
|
sajjadg |
cem_, maven is better. lot better. ant is not comparable to maven. maybe you need to compare maven to ant/ivy |
| 20:05 |
|
sajjadg |
I prefer eclipselink to hibernate |
| 20:05 |
|
sajjadg |
it's faster for pg and oracle |
| 20:06 |
|
neuro_sys |
I'm using postgresql for this one, maybe should try eclipselink to add it into my repertoire of tools |
| 20:06 |

| 20:07 |

yeah comparing maven and ant isnt really a comparison. ant exposes deep subtle control of a build, maven automates external dependencies in ways ant cannot do easily |
| 20:07 |
|
neuro_sys |
and gotta love visual mode |
| 20:07 |
|
neuro_sys |
ant is so much like writing a custom shell script |
| 20:07 |
|
neuro_sys |
:p |
| 20:07 |
|
sfisque |
ant is basicallly make |
| 20:07 |
|
neuro_sys |
copy things around, run commands |
| 20:08 |
|
sfisque |
maven is more like apt or similar "management system" |
| 20:08 |
|
cem_ |
sfisque: i want know how to use ant first , guess maven more like framework |
| 20:08 |
|
neuro_sys |
ant is not a prerequisite for learning maven though |
| 20:08 |
|
neuro_sys |
the latter of which is easier anyways |
| 20:08 |
|
sfisque |
both are frameworks. ant is closer to a scripting system. maven is more of a build harness |
| 20:11 |
|
sess |
sfisque: "deep subtle control" that is usually not needed and more harmful than gain |
| 20:12 |
|
sess |
plus maven has the ant plugin for when you _really_ need that custom behaviour |
| 20:15 |
|
sajjadg |
what about gradle guys? I see spring and google are moving from maven to gradle! I don't see any advantages in gradle (despite from non-xml config) |
| 20:15 |
|
sajjadg |
? |
| 20:15 |
|
sajjadg |
neuro_sys, use RESTful application + SPA (with angularjs) |
| 20:18 |
|
cem_ |
#ppl will go mad :P |
| 20:18 |
|
sfisque |
depends sess. if you're integrating systems that aren't all java, ant will handle that transparently. ant doesnt care if you're building 100% java or boot strapping several different languages in a build. i am unsure if maven has that flexibility off the shelf. and yes, you can plug ant into maven, but then if you need that, it introduces the thought of why they aren't using ant/ivy |
| 20:19 |
|
neuro_sys |
sajjadg: by RESTful application, do you mean decoupling all the service layer to rest services? |
| 20:19 |
|
sfisque |
ultimately it comes down to using the tools that fit the need |
| 20:19 |
|
neuro_sys |
as in db interaction and business/domain logic? |
| 20:21 |
|
sajjadg |
neuro_sys, yes. REST separates server-side programming from client-side and angularjs is a very good framework for creating SPA and works good with REST architecture. JAX-RS+angular |
| 20:21 |
|
sess |
sfisque: well I can't answer for those situations, i've never combined java with anything else |
| 20:21 |
|
sess |
it sounds fairly uncommon |
| 20:23 |
|
sfisque |
uncommon, yes. but they do exist (from experience) |
| 20:24 |
|
neuro_sys |
sajjadg: ah, so the frontend would have all the app logic (as opposed to using a serverside MVC, like JSF)? |
| 20:24 |
|
sajjadg |
neuro_sys, yeah |
| 20:24 |
|
neuro_sys |
and the frontend MVC (angularjs) would talk directly to the RESTful server? |
| 20:24 |
|
neuro_sys |
now umm, I wonder about the session |
| 20:25 |
|
sfisque |
rest == no session |
| 20:25 |
|
sajjadg |
trends.google.com is a good example of an angularjs site. |
| 20:27 |
|
sfisque |
you can "fake" a session with things like a header cookie, but that's counter to the whole rest concept of "resources stored at addresses" |
| 20:27 |

so, how do you get the user have a session, like say a login session and for instance a shopping cart? (by keeping all the user session in DB?) |

you don't. that's what servlets are for |

rest is "supposed" to model the concept that a URI corresponds to a resource that you act upon (GET, PUT, DELETE, POST, etc.) |
| 20:29 |
|

the action is supposed to be "atomic" and not a "workflow" |
| 20:30 |
|
sfisque |
if you need a workflow you should be using a traditional web framework |
| 20:30 |
|
sfisque |
otherwise you're embedding alot of session/security/etc. into the remote client |
| 20:30 |
|
neuro_sys |
yeah, I see the simplicity in that. states are evil. |
| 20:31 |
|
sfisque |
since the whole "semantic web" thing hasnt really happened, rest has been "morphed" into a sort of data conduit system with session/state embedded using cookies or tokens or similar |

I've barely no frontend JS framework knowledge, I'll be looking into angularJS as a starter |
