Hi All ,

   I have been trying load balancing with JBoss AS 7 and achieved it using mod_jk using a simple servlet application. I tried to do the same with JBPM 5.2 but unfotunately came up with some error.I was able to launch the jbpm console but after logging in, it showed me a blank screen . The error log in the server is given below- 


14:57:48,654 ERROR [org.apache.catalina.core.ContainerBase.[jboss.web].[default-host].[/jbpm-console].[ErraiServlet]] (http-localhost-127.0.0.1-8080-12) Servlet.service() for servlet ErraiServlet threw exception: java.lang.IllegalArgumentException: clusteredSession.setAttribute.iae
