Summary

0004254: session/hessian classloader issue 4.0.9

Description

(rep by Steven Nicholai)

I?ve added the following logger to resin.xml

   <logger name=?com.caucho.hessian.io.SerializerFactory? level=?finer?/>

We?re seeing these errors when the browser is left alone for 45+ minutes (much longer than the 30 minute session timeout.)

It seems that resin is trying to reconstitute the timedout session using the system classloader rather than the webapp classloader, which fails.

Any hints for debugging classloader issues in resin?
