Losing Session for Weblogic 7.0.2 in Cluster env

Question

          PROBLEM: We are losing our session when running in our app in a clustered environment.
          The user can use the app for a while, but then weird stuff starts happening. In
          some cases, the login check that we do at the begining of each request fails,
          because it tries to check for a login token in the session, and the session has
          been wiped out. The user gets forwarded to the login page.
          Our configuration is: WLS 7.0.2 (OS = Windows 2000) Admin Server and a managed
          server A at APP1 (physical machine), another managed server B at APP2 (physical
          machine), A and B is in one cluster. We had 6 Apache Servers 2.0.45 (OS = Linux)
          and each works together with Weblogic Plugin. The weblogic plugin has the following
          configuration: <Location /sample> SetHandler weblogic-handler WeblogicCluster
          10.1.1.11:7010,10.1.1.12:7010 Idempotent ON CookieName JSESSIONID </Location>
          The server A and B use round-robin loadblancing, and we have a hardware loadblancer
          infront of Apache to do loadblancing for our 6 web servers.
          In weblogic.xml we config our application to use replicated for session failover.
          Losing session is randomly happened.
          Anyone of you have any idea?
          Thanks in advance.

Answer 1

The advice on version numbers given above is quite generic. While JDK 1.4 may work, if you want to run a supported configuration the answer to this question depends on what OS you're running. Further, BEA supports different JDK versions for running the server and for client applications. Here is the whole chart:

Be sure to click on your operating system to get the specific information about what JDK is "fully-supported" and what is "client-only".
Hope that helps,
