[jboss-user] [Clustering/JBoss] - problem with session, logging log4j

Hi I have app which were running in cluster and was configured in that way. Now i need run this app on one host. I have problem when my app calls function request.getSession(). It returns null and i got NullPointerException in code like below. | request.getSession().getAttribute(...); | request.getSession().setAttribute(..., ....); | Something is strange, because i see this behavoiur only if I set up log4j with ERROR for com.myapp (turn off debugging in production env). When I turn debug on, everything is OK. Version: 4.0.3SP1(build: CVSTag=JBoss_4_0_3_SP1 date=200510231054) JVM Version: 1.5.0-b64 (Sun Microsystems Inc.) OS: Linux 2.6.11.4-20a-smp (i386) Any suggestions? It's problem with session replication?
