Attached is the file we use for the JBoss5 client jars when conecting to a JBoss5 server (remote EJB) from a JBoss7.1 client.

Also, in our jboss-deployment-structure.xml file we exclude both "org.picketbox" and "org.jboss.logging" in order for this to work.

Since I cannot figure out how to upload more than 1 attachment, here is the jboss-deployment-structure.xml file for one of our projects:

<jboss-deployment-structure>

    <sub-deployment name="webapplication-war.war">

      <dependencies>

         <module name="net.sourceforge.jtds"/>

      </dependencies>

      <!-- exclusions to allow connecting to JBoss5 clients -->

      <exclusions>

         <module name="org.picketbox"/>

         <module name="org.jboss.logging"/>

      </exclusions>

   </sub-deployment>

</jboss-deployment-structure>

So far we haven't run into any problems, but you may need to be careful about the things you add to your dependencies list too.

So far, I do not know how to connect to a JBoss7.1 server from JBoss5
