I dont know what has happened, but I was able to run servlets without a problem, but lately I dont know what has changed but I can not run servlets anymore. I get an error message like java.lang.NoClassDeffFound : javax/servlet/http/HttpServlet
and a whole bunch of the exception stack trace which does not mention my pogram.
Can someone help me out here ?
Thanks.
Herbert

That sounds like a problem with class library incompatibility - I had a bunch of mystery messages like that due to an old JSKD.jar file hanging around. Have you installed any new Java related programs that might have added a jar file somewhere?

Yea, I added quite a few. I added the JSDK which did not work, always complained about some unknown errors.Then I installed JWSDK, without uninstalling the JSDK, this did not work too, and finally nothing worked any more. DO you think this might be the cause ? Do you think I need to uninstall this other stuff ?
