Yep, adding servlet.jar to the classpath did the trick! Thanks! -----Original Message----- From: Larry Isaacs [mailto:[EMAIL PROTECTED]] Sent: Tuesday, February 04, 2003 3:14 PM To: Tomcat Users List Subject: RE: Tomcat 3.3.1 HttpSessionBindingListener not found
This means that the class that Class.ForName() is trying to load has a dependency chain that includes a class that has a dependency on HttpSessionBindingListener, i.e. servlet.jar. That class with the servlet.jar dependency is being found in a classloader that is below (i.e. a parent,) of the "TOMCAT_HOME/lib/common" classloader that contains servlet.jar. Thus it can't see servlet.jar classes. This class is likely to be in the CLASSPATH or extension directory. If you haven't messed with the CLASSPATH, then check the extensions directory. It is probably likely that this class is a duplicate of one that is located in the proper location. The systems that work don't have this duplicate in the wrong location. HTH.
