I faced the similar type of problem , which was solved by copying commons-logging.jar to the \applib folder .

I had this problem and found the following solution works for me :-

Edit the file:

<Eclipse Home\plugins\com.objectlearn.jdt.j2ee_3.0.1\servers\tomcat50x.server

Replacing this:

-Djava.endorsed.dirs="${serverRootDirectory}/bin;${serverRootDirectory}/common/endorsed"

With this:

-Djava.endorsed.dirs="${serverRootDirectory}/common/endorsed">

Be sure that commons-discovery.jar is on your classpath.
