....and I am running JBoss 3.2.3 on jvm ibm 1.4.1
I've got the same issue running on AIX 5.3, JRE 1.5.0. In my case, though, JBoss is running on AIX and one EJB is invoking a method on another EJB within the same instance of JBoss.
The same thing works when I run it on Windows. Anyone know what could be causing this?
