The given link from https://community.jboss.org/people/jason.greene Jason Greene will
show a soltution with the remoting-project which is marked as deprecated.
I recommend to not use this approach except as workaround.
I hope that the EJBCLIENT-34 will solve most of the trouble with the new ejb remote calls

What? What exactly is deprecated?

I don't think that's deprecated. Personally I didn't use that approach because
I had lots of difficulties using EJBClientContext.setSelector(this.selector) because I was
trying to invoke EJB's in one container instance from inside another instance. Firstly
the setSelector has permissions locked from the security manager and secondly the JTS
couldn't commit the transaction. The transaction manager commit runs in another thread
with another classloader and I had no control over the client context it tries to use.

Right you would have to use reflection to access our selector:
https://github.com/jbossas/jboss-as/blob/master/ejb3/src/main/java/org/jb...
https://github.com/jbossas/jboss-as/blob/master/ejb3/src/main/java/org/jb...
And then do some kind of alter connect change and restore. Unfortunately due to a bug, you
would have to control the transaction manually.
If you are using JTS though, and you want to participate in container transactions on the
client side (the one making the remote call) you could look at using IIOP, it allows you
to dynamically register a connection.
I have bookmarked your usecase with the work we are doing in EJBCLIENT-34. I hope to make
sure it is covered without any hacking.

Just out of curiousity, what was really wrong with providing a URL to initial context?
I remember initial posts about AS 7 saying that the main reason for dropping it was that
is was not in the Java EE and EJB specs, and JBoss wanted to explore alternative ways.
Maybe I've missed a post, but I've never really seen an explanation that detailed
what was really wrong with the URL approach.

Thanks. I am using IIOP. From what tests I have done it appears to work well. Actually, I
would suggest that using IIOP could be the solution to the original problem. Aside from
offering JTS support it allows a hostname:port style API which is much more "JBoss
4,5,6" as James put it.

This was a bug which we just
fixed and a pull request has been sent. I think we should be able to merge this to AS7
upstream by tomorrow. I'll let you know once it's available in a nightly build.
