1/ make note of any vendor-specific hooks you use in your current app.
Don't expect them to be in the other container.  Rewrite your app to

2/ Review the servlet spec that fits the destination container (v2.4 for
Tomcat 5).  If it's not the same servlet spec version as your current
container, make note of any deprecations (such as SingleThreadModel) or
other changes.  Code your app to work per the spec.
