We are using jboss-3.2.3 to deploy our software. We are using stateful and stateless session bean, CMP and BMP beans in our software. The ear file could be deployed successfully and run. Our problem is that when the use access stateful session bean, the server swap some data between different sessions. This occurs after the system have running for a while. We moved our software to jboss-3.0.8_tomcat-4.1.24 and running without any problem. We want to know if we should configure the session in the jboss-3.2.3 to manage the session better. Please help and thanks in advance.
