I am writing a deployer for SwitchYard[1], basically migrating the AS6 code to AS7. I have
created some basic Subsystem code that deploys the artifact (a jar file containing
switchyard.xml). 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:
Caused by: javax.naming.NamingException: Failed to get context with name comp

I know the code says that the NamespaceContextSelector is null. Is this by design? What
should I do to get the JNDI namespace? 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?
I could see these dependencies in my app that was compiled from[4], it shows that I have a
BeanManager @java:module/BeanManager, just the lookup fails.

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.
