Dear Prasun,
R u using Impl bean? I've worked in an autoportal. There we used the impl in
beanid, like bean id="testBeanImpl".
If not, just check if u've set the classpath properly.

JSP pages do not compile every time you request them. They compile only on the
first request and many application servers (not sure about Websphere) have an
option to compile before you deploy.

You don't need to tell JRun or IIS that your own directory is the root for
JSP pages. You do have to set up a website alias in IIS that points to your
directory containing JSP pages-- using the IIS manager, right-click your
website and choose New -- Virtual directory. Point it at your directory.
If you have the "Use Session Persistence Engine" option checked on the Session
Tracking tab of the JRun Admin Application (under JSE--Service Config), then
JRun is going to serialize active sessions when you shutdown the servlet engine.
It's a feature.
