classNotFound exception in servlet bridge [message #64073]

I am using the equinox servlet bridge with tomcat. When a servlet in a
bundle is invoked its bundle activator does not seem to be called(I have
checked activate bundle in the manifest). Also if this bundle has
dependencies on other bundles, if I reference then in the doGet(...)
method, I get a classnotfound exception.
I check that my bundle in resolved but not active. Can anyone throw some
light why I am getting a classNotFound exception for classes in my
required bundles of the servlet bundle.

Thanks
Kiran

Hi Kiran,
It sounds to me like a dependency is missing somewhere in your servlet's
bundle.
It's not activating because it's throwing an exception in start().
You should walk through this code in a debugger, potentially catching
ClassNotFoundExceptions until you can figure out which import your bundle is
missing.
I find that calling start from the console sometimes helps. Be suspicious of
any of the direct dependencies of CNF Exception class.

Hope this helps.

I downloaded the application which was published on infonia. I get this
exception even with a very simple bundle dependency.
org.rsp.demo is a simple class with one class Customer whose package is
exported.

If I refer to this class in MyServlet.java(this plugin has specified
required bundle on org.rsp.demo) I get an exception. This is the only
bundle I have a depedency on. org.rsp.sample.usage.servlet has a extension
on org.eclipse.equinox.servlet.ext.servlets.

Is there a demo application anywhere which uses Tomcat and Eclipse
together on the equinox site.
