[Design of AOP on JBoss (Aspects/JBoss)] - Re: AOP asintegration WITHOUT the integration :-)

That's the second part of completing the aop/metadata stuff. A scoped deployment should be able to aspectize a class (e.g. the OracleConnection) in a different way to the non-scoped usage (which might not even be aspectized). I proposed it should be a function of what metadata context creates the Object (Class instance) and so would require extra work to intercept the instantiation and check the context to see whether a proxy is needed instead of the original (aspectized) class in a scoped environment. You might be able to think of a more efficient way to do this? Especially for when the default scope doesn't want an aspectized version of the class.

[Design of JCA on JBoss] - Re: Resource adapter transaction timeout enforcement

"adrian(a)jboss.org" wrote : For a general XAResource you should do both. | There should be a real (local) timeout in the backend and frontend timeout to cover network splits, etc. Ok, that makes sense. "adrian(a)jboss.org" wrote : My question is why are you using an XAResource for remoting? What state do you have to persist during prepare? Do you really need to vote in 2PC? Remoting has no state, or direct awareness of transactions. However, whatever service you're connecting to by way of Remoting may (and probably does). The reason Remoting 3 has this capability is so that there's a single standard way to propagate transaction state between endpoints - whether it's a database to an app server, two app servers together, or two client applications that don't even know anything about JTA or JCA or anything like that.

"kabir.khan(a)jboss.com" wrote : | Are you saying "don't use it", or "use it and we'll retrofit an SPI"? :-) As far as I can tell I will need information from the ClassLoaderPolicy. I'm saying any use of the classloading metadata for the AOP domain construction would be a hack until we have a real solution based on metadata context rather than the classloader of the aspectized class/aspect class/joinpoint. The latter (classloader solution) is just a temporary solution to reproduce what jboss4 does. I don't think we need to create a SPI (which we will need to support forever) for something that is a temporary hack. If we created a SPI, it wouldn't be the Unified ClassLoader or the new classloader it would have to cover all possible classloading models that people might want to plugin to the deployers.

[Design of JCA on JBoss] - Re: Resource adapter transaction timeout enforcement

by adrian＠jboss.org

For a general XAResource you should do both. There should be a real (local) timeout in the backend and frontend timeout to cover network splits, etc. My question is why are you using an XAResource for remoting? What state do you have to persist during prepare? Do you really need to vote in 2PC? If you have no state and therefore don't need to recover or vote then you should use a TransactionSynchronization instead.

[Design of POJO Server] - Re: Unifying metadata

by alex.loubyansky＠jboss.com

Yes, as Carlo wrote there are three subclasses of the MethodMetaData. In which sense it's not a complete replacement? It seems to have all the public methods of the old one. Except for addParam and importEjbJarXml that are used during parsing.

[Design of JBoss jBPM] - Re: committing log.debug 'protection'

by kukeltje

I thought I'd just ask because lots of files are changed and if someone has a large changeset locally, it is best that that is checked in first since I can re-run this anytime in a few minutes.

[Design of POJO Server] - Re: Unifying metadata

by wolfc

As far as I can see in server MethodMetaData is instantiated either in ApplicationMetaData or in the EjbJarObjectFactory. In the new project ApplicationMetaData is only a delegator, which instantiates (indirectly) subclasses of org.jboss.metadata.MethodMetaData as delegators, so the EjbJarFactory needs to use the new model and create the ApplicationMetaData delegator instead. It should work, but shouldn't we ditch all the old stuff?

[Design of JBoss Build System] - Re: Eclipse:eclipse settings for parent pom

by wolfc

I'm seeing some classpath settings screwed up, because this got removed (see http://www.jboss.com/index.html?module=bb&op=viewtopic&t=105740). But is it possible to include the eclipse profile in the parent?
