Does anybody know how to connect with JBoss4.0.5GA in Seam2.2.0GA unit test? I'm using Seam2.2.0GA with the embeded JBoss to run the unit test, the module needs to call old JBoss server (EJB2, because the vendor locked in JCA has to deploy on old JBoss). it's typical seam test case, and I can't get it connect to JBoss4.0.5GA by using jbossall-client.jar from JBoss4.0.5GA. so far I tested the embeded JBoss can only working with JBoss5.X server.

with JBoss4.2.3GA, it report:

[testng] java.rmi.MarshalException: Failed to communicate.  Problem during marshalling/unmarshalling; nested exception is: 
[testng]    java.net.SocketException: end of file
[testng]    at org.jboss.remoting.transport.socket.SocketClientInvoker.handleException(SocketClientInvoker.java:122)

[testng]    at org.jboss.remoting.Client.invoke(Client.java:1634)
[testng]    at org.jboss.remoting.Client.invoke(Client.java:548)

This is the best result I could get (JBoss5.1.0GA jbossall-client.jar call JBoss4.2.3GA server in the embeded JBoss env), here is the ant script:

<testng classpathref="build.test.classpath" outputDir="${target.test-reports.dir}" haltOnfailure="true">
    <jvmarg line="-Dsun.lang.ClassLoader.allowArraySyntax=true" />
    <jvmarg line="-Dorg.jboss.j2ee.Serialization=true" />
    <!--
    <jvmarg line="-Djboss.remoting.pre_2_0_compatible=true" />
    -->
    <jvmarg line="-Djboss.jndi.url=jnp://localhost:1099" />
    <xmlfileset dir="src/test/java" includes="${ant.project.name}-testsuite.xml" />
</testng>

Can anybody help?
