Description Dave Hodson 2004-12-31 01:34:58 UTC 
I have two machines in a cluster configuration. An initial start of each works
properly, with sessions being shared, etc. Stopping one Tomcat instance works
and I can continue as the other Tomcat instance also has my session.

However, when I restart the stopped Tomcat instance, it refuses to load the
context (in my case, an app named "Config").  

It seems to be complaining about a ClassNotFound exception for
util.MessageResourcesFactory  - MessageResourcesFactory.createFactory, however,
this class is found on the initial startup (before shutdown) and I am able have
session replicate initially also.

Stack trace (restart) below:

Comment 1 Filip Hanik 2005-02-09 15:58:03 UTC 
During a state transfer, I am now setting the context class loader correctly, so
that static methods like struts can load their classes properly.
Comment 2 Darian 2005-02-16 08:31:45 UTC 
I am also having this problem, can you clarify the fix?  Is this a code change,
if so is a patch avail or can you direct me to the classes you modified?  I
tried 5.0.30 and had the same problem.
