by vchira

[jBPM Development] - Re: interested in contributing ?

by sebastian.s

I see no point in your question. Since jBPM is an open source project why souldn't it be possible to contribute? And this sticky post here already explains a lot. I checked out the sources a couple of days ago and it worked fine for me using this url: https://anonsvn.jboss.org/repos/jbpm/ Google search for: jBPM "building from source" the second result leads you to this step-by-step manual: http://labs.jboss.com/community/wiki/jBPM4BuildingfromSource%20%20.pdf View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4262944#4262944 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4262944

[jBPM Development] - Re: Multiple instances with synchronization

by sebastian.s

My question to the dev's would be: What is the reason that it is not implemented in jBPM? Is this due to a lack of interest from users or due to being a low priority feature? Or is there a technical / architectural problem and so it is no possible or very difficult to implement? Or is it possible and a concept how to implement this is missing? Looking forward to your comments.

[JBoss Microcontainer Development POJO Server] - Re: integration with the Papaki annotation indexer/repositor

by alesj

"emuckenhuber" wrote : | * jboss-metadata - for example jboss-metadata is just asking the AE to get a list of classes which have a given top-level annotation (e.g. @Stateful).

Because this info is already present if we use McAnn, as McAnn already uses JBoss Reflect, and Reflect caches this info. And this also shows that things go hand in hand, and that this inheritance check should not be part of annotation scanning. Not to mention another very good example why re-using existing libs is good. ;-) "emuckenhuber" wrote : | Beside jboss-metadata there are not many users of AnnotationEnvironment, but we really should avoid having things like getClassloader().loadClass(metaData.getClassName()).getAnnotation(X) if possible. | Sure, leave it to JBoss Reflect.

Either as part of ScanningMetaData or AnnotationScanner's DeploymentUnit filters. * e.g. http://anonsvn.jboss.org/repos/jbossas/branches/Branch_5_x/server/src/mai...

[jBPM Development] - Re: interested in contributing ?

by vchira

hi. how can one contribute with code to jBPM? ist it possible? is there a description how i could check out and compile jBPM(The anonymous SVN links from jBPM page are not working.? I am interested into contributing code comments, API refactorings (I am quite good at API design) and also features.

Cool, Let me know when you have checked it and I can add this to AbstractController. One minor issue is the iterator() and listIterator() methods, which are not thread safe at the moment. The other methods are called with a lock taken in AbstractController. For the iterator methods I need to readLock, take a snapshot into a list and return iterators to that list. Another thing I have not checked is how states work in a hierarchy of controllers View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4262931#4262931 Reply to the post : http://www.jboss.org/index.html?module=bb&op=posting&mode=reply&p=4262931

[Embedded JBoss Development] - Re: Embedded and Bootstrap Development

by manuel.chinea

ALR, i checked out the code last night and saw it. Also saw the jira issue and its dependency. If i undestand correctly, the sub-projects arde divided this way: bootstrap-api, bootstrap-spi and bootstrap-impl, and the depend from one another in this way: impl depends on spi, spi depends on api. Also, each one of them is spplitted in base, as and mc (as depends on mc, mc on base). Now, the bug. checking the class BasicJBossASServerConfig, i see no reference to any server object. I also see BasicJBossASServerConfig has this annotation @ManagementObject(name = "jboss.system:type=ServerConfig"...). The closest "server" class i found is AbstractJBossASServerBase, which has this annotation @ManagementObject(name = AbstractJBossASServerBase.NAME_MANAGEMENT_OBJECT...). Now, i should use some lookup mechanism to get the server object in the config (1), or simply put a reference to the "server" object? (2) (i don't want to break any architectural or design decision here). If (1) is the answer, what would be the correct mechanism?. (or a third one, (1) + (2) using annotations?).

Looks good. I need to check the test, if you're not actually having "375 - new Random(50).nextInt()" in it for your model stopwatch. :-) But this means you'll have to properly clean out all "states" variable usage in AbstractController. Which will also help once we move to a more generic (aka non-linear) model. Meaning we would only have to change some pieces of the model, but not any of the logic of AbstractController.
