OK... That part I already got working... The applet/servlet will load fine if I have a set of JARs in WEB-INF/lib and eBMF (for the applet).
This setup will result in VerifyErrors for classes in library.jar. Since both the applet and servlet use these classes I have this JAR file in the two places (as noted above). The classes in library.jar that give this problem are DAO type objects that get serialized and sent back to the server by the (client) applet. It seems that the servlet will attempt to load these classes from two different sources???? For one it uses the serialized version (streamed from the client applet) and it also attempts to load the class from WEB-INF/lib/library.jar at which point the VerifyError is thrown?

Anything under WEB-INF is invisible to a web user, it's just the way things are. Hence, I believe that you are going to need to put the library.jar in two places, once in the WEB-INF/lib and once in the same dir as applet.jar (but not under WEB-INF) Michael Petres wrote: >Hello, > >I have a problem that is probably silly if you know tomcat well& > >I have configured tomcat to load a context (eBMF).
