[JBoss-user] Error accessing EJB by a Servlet - Unable to activate POA

[<Pap...@gm...>]

Hello,

I've got a problem accessing a Stateless SessionBean via a Servlet.
A SLSB (Source: http://pastebin.ca/118516 ) is bound to JNDI "vfmcontroller/VFMController"
and in the Deployment-Descriptor (Source: http://pastebin.ca/118520 ) I've configured it
to be accessible by IIOP, since I've got to access it from a C#-Client (IIOP.Net).

In a very simple Servlet (Source: http://pastebin.ca/118535 ) I try to create a new
InitialContext and looks up this SLSB.


Starting JBoss and deploying my EAR works fine without any logged errors and I can
access my SLSB from my C#-Client. (Nevertheless I still can't access it thru a Standalone-Java-Client...)

But calling my Servlet generates a "java.lang.Error: POA: not configured!" in my service()-Method,
which I catch and log (See http://pastebin.ca/118532 for StackTrace).
My JBoss Logs state "[listener] Address already in use: JVM_Bind", "org.jacorb.orb.iiop.IIOPListener$Acceptor.createServerSocket(IIOPListener.java:466)"
and "Unable to activate POA" (See http://pastebin.ca/118529 for StackTrace).
As far as I can read out of the sourcecode, IIOPListener fails to look up the RootPOA (due to "Address already in use" ?)
If I got it right, this Port might correspond to "OAPort" in jacorb.properties, but changing did not have any effect.

Nevertheless, netstat tells me that all JBoss-relevant Ports (8080, 8083, 1098, 1099, 3528) are just
used by the one and single java-Process (JBoss).



Environment:

- JBoss 4.0.4GA "ou-of-the-box", the only thing I've changed was that I've dropped "jnp-context"
  from the "the "invoker-proxy-binding" in file "conf/standardjboss.xml".
- JDK 1.5.0 (build 1.5.0_06-b05)
- Windows XP SP 2



What makes me wonder is that I (almost) haven't changed any configuraion of JBoss .. !?

I simply have no idea why this error shows up and how to fix it,
I just want to access my EJBs thru my Web-App !?
