aye. you dont need to manipulate byte code for that. you can just build an environment (interpreter or parser/compiler or some hybrid) |

is there a type safe way to reference a class from a JSF page? |
| 18:01 |
|
sfisque |
the only way i know is via code completion. nb will only complete if the references are valid |
| 18:01 |
|
sfisque |
and it will highlight if the reference is questionable |
| 18:02 |
|
sfisque |
problem is scope. the facelet isnt compiled until runtime so you have the "late binding" issue |
| 18:02 |
|
pdurbin |
hmm |
| 18:02 |
|
pdurbin |
well, here's an example: rendered="#{permissionServiceBean.on(SearchIncludeFragment.dataverse).canIssueCommand('DatasetCreateCommand')}" |
| 18:02 |
|
pdurbin |
DatasetCreateCommand is the name of a class |
| 18:03 |
|
pdurbin |
and if we refactor and rename that class we'll get a ClassNotFoundException but only a runtime, when you hit the xhtml page with that render |
| 18:03 |
|
pdurbin |
feels brittle |
| 18:06 |
|
pdurbin |
having the name of a class in the xhtml |
| 18:06 |
|
|
AlexCzar joined ##javaee |
| 18:07 |
|
sfisque |
not really. NB refactor will update facelet references |
| 18:07 |
|
sfisque |
if you use the refactor tool and not "by hand" |
| 18:07 |
|
pdurbin |
sfisque: even though that's just a string? 'DatasetCreateCommand' in single quotes like that? |
| 18:07 |
|
sfisque |
oh |
| 18:08 |
|
sfisque |
that might not get caught then |
| 18:08 |
|
pdurbin |
:( |
| 18:08 |
|
sfisque |
begs the question though |
| 18:08 |
|
sfisque |
why are you embedding business logic that high up? |
| 18:08 |
|
pdurbin |
excellent question. I'm raising red flags about it |
| 18:08 |
|
sfisque |
expose the reference via a accessor/mutator |
| 18:08 |
|
sfisque |
that way it follows the "bean" semantics |
| 18:09 |
|
pdurbin |
yeah, an accessor in the backing bean, you mean, right? |
| 18:09 |
|
pdurbin |
the backing bean for that page |
| 18:09 |
|
sfisque |
yes |
| 18:10 |
|
sfisque |
or proxy the reference in a "side" bean that is @Named |
| 18:10 |
|
pdurbin |
ok. that's what I was planning to do on this page away |
| 18:12 |
|
pdurbin |
the accessor thing |
| 18:12 |
|
sfisque |
aye |
| 19:23 |
|
pdurbin |
ok, committed a fix |
| 19:23 |
|
pdurbin |
sfisque: thanks |
| 19:23 |
|
pdurbin |
sfisque: not sure what you mean about a proxy side bean thing, but that's ok :) |
| 19:24 |
|
sfisque |
instead of exposing it directly in the pages controller, have a separate @Named been that is in scope (View, Convo, Session, etc.) that handles that particular detail. especially if it's somethign that is pervasive and not tied to a single page |
| 19:25 |
|
pdurbin |
hmm. permissions are pretty pervasive |
| 19:28 |
|
sfisque |
aye so having a separate "permission controller bean" that remains in scope for the session might be the way to go, and then you can reference it in any pages that need it, that way it's not tied to several controllers |
| 19:44 |
|
pdurbin |
sounds like something we should consider |

I discovered that I am having some SOAP webservice issue that is not relevant to an IDE. The issue is similar to the mentioned link at last. I see terminated status with not warning, nor any of my code is executed . e.g no System.out.println("hello world"); http://stackoverflow.com/questions/14410356/console-shows-terminated-message-in-eclipse any help? |

Also does it print System.err? |

also, what about when you run it via command line, and not an IDE? |
| 21:11 |
|

let me see and do System.err("test"); ? |

"there have been rumblings of varying sizes on the topic of an action oriented web framework in Java EE 8" |
| 23:06 |
|
sfisque |
do they mean "like struts" or is this some new type of beast |
| 23:07 |
|
pdurbin |
"I'd like to see us extract Facelets from JSF, make it a first class citizen of a JAX-RS MVC, *and* provide an Action Oriented lifecycle as an alternative to the standard JSF lifecycle." -- Ed Burns |

sfisque |
WOO |
| 23:08 |
|
sfisque |
in so many words… yes, like struts/tiles |
| 23:08 |
|
sfisque |
maybe now we'll get "the best of both worlds". view based AND component based woven into one framework |
| 23:08 |
|
sfisque |
about time |

to be honest, I don't know the difference between JSF and Struts. I've only used the former. |
| 23:19 |
|
sfisque |
in one sentence: struts == action/url -> view / JSF == component -> activity -> response |
| 23:19 |
|
sfisque |
very different paradigm but both powerful and answer different problems |
| 23:19 |
|

| 23:28 |

pdurbin |
so struts is more oriented around URLs, it sounds like. maybe more like django in that way, which is all about routes |
