[jboss-dev-forums] [Design the new POJO MicroContainer] - Deploying MC 2.0 snapshot in JBoss 4.0x

[kabir.khan@jboss.com]

I am trying to get things ready for an AOP 2.0 alpha release, and since AOP now depends a lot more on the microcontainer I need to get the jboss-beans.deployer from head deployed in Branch_4_0. (This is just trying it out, I will package a real release later on).

Classes that definitely are missing in JBoss 4.0 are:
org.jboss.deployment.SchemaResolverSimpleSubDeployerSupport
org.jboss.util.collection.WeakClassCache (moved from org.jboss.util.connection since jboss 4.0.x)
org.jboss.util.collection.CollectionsFactory (moved from org.jboss.util.connection since jboss 4.0.x)

After adding these missing classes I am able to get the JBossBeanDeployer started, but when starting web services I get the following error

  |    private static void configureValueBindings(TypeBinding typeBinding)
  |    {
  |       // type has values
  |       typeBinding.pushInterceptor(valueQName, VALUES);  <- failure
  | 	
  | 	...
  |    }
  | 

The typeBinding passed in to BeanSchemaBinding.configureValueBindings() is null. I'm not that familiar with JBoss XB, is there a simple explanation? Is there anything else I need to configure?

BTW the null type binding seems to be obtained via

  |       // classloader binding
  |       TypeBinding classloaderType = schemaBinding.getType(classloaderTypeQName);
  |       configureValueBindings(classloaderType);
  |       classloaderType.setHandler(new DefaultElementHandler()
