Hi,
We're using Tomcat 5.5.9 on our development PCs because it closely
replicates our chosen production environment (JBoss 4.0.2). What we
would like to do is configure Tomcat to enforce that all session
variables must be Serializable, so any development errors are caught
early and not during integration testing.
To achieve this I have added "<distributable/>" to our application's
web.xml, and added a "Manager" with distributable set to true in the
Tomcat server.xml (complete file included below).
However, when testing an object that implements Serializable, but has
non-transient instance variables that don't (e.g. org.w3c.dom.Document)
Tomcat accepts setting it in the session - no stack traces in the
console, nothing written to the log files.
Also, if I shutdown the server mid-sequence, the "SESSIONS.ser" file is
updated but is only ever 81 bytes, so I'm not sure it's working
properly?
Are we doing something wrong, or is this a known issue either resolved
in more recent builds or planned to be resolved?
