See - http://tomcat.apache.org/faq/classnotfound.html
Odds are you have your own servlet-api.jar somewhere in the webapp or system
classpath and that is conflicting with the one in common/lib (installed by
tomcat)

Please forgive my intrusion if this is not the proper place to post a questoon
of this sort. I am new to servlets, and am working on my first deployment- but
I am running in to a problem that I can't find a solution to. I have installed
Tomcat 5.5 and am using Eclipse (as well as a tomcat plugin) to manage my
project. A colleague of mine sent me a war file of out working projected,
which I imported to my IDE. I start tomcat, which seems to load properly, and
attempt to run the project on the server- where I am faced with the following:

I am using the most recent J2RE 5 and I am certain that Tomcat's
servlet-api.jar is within my application's class path. I am not sure why the
source cannot be found. Any helpin locating my problem would be greatly
appreciated, and I would be happy to prove more information if needed (I'm not
entirely sure what would be helpful). And again, I am sorry if this is not the
place for this kind of question!Happy coding!John
