How do I disable session persistence in Tomcat?
Locate the relevant Context element in either server.xml or in the context descriptor and declare the no-op session manager.


<Context .. >
  <Manager pathname="" />
</Context>

Disabling this Tomcat feature is discussed in this forum thread. Disabling session persistence for Academus and uPortal is desirable because non-serializable classes may be present in a normal uPortal user session.
