[jboss-as7-dev] Subsystem/Deployers

[David M. Lloyd]

The right way to get the selector for your namespace is to use the API 
presented by org.jboss.as.naming.context.NamespaceContextSelector, which 
lets you push/pop contexts into the current thread.  It should go 
without saying that you should pop any contexts you push before 
returning from your method, but I'll say it anyway. :-)

In order to acquire your JavaEE namespace you have to know what EE 
component, module, and application you're executing in the context of.

Now in order to integrate with Weld (the one and only implementation, that we have in SwitchYard), I would like to migrate the AS6 deployer code to AS7. While doing so I encounter the following error:

I transformed the code to use org.jboss.msc.service.Service and it still doesn't help. Is this a *right* way to do stuff? Do you have any advice on how to proceed with this naming issue?
