Christopher, There is an easier solution, although it has limits. Since the Tomcat binaries include servlet.jar, we can put "-Djava.ext.dirs=" as an argument in the Tomcat scripts. This argument causes the JVM to ignore any jars in its jre/lib/ext directory so that there is no conflict between the jars shipped with your application (Tomcat in this case) and the jars in your JVM's jre/lib/ext directory. I think that this solution may also eliminate the vexing problem where the JSSE jars are in jre/lib/ext as well.
Does this sound like a reasonable solution? If so, I can implement this in the Tomcat scripts with minimal effort. Patrick "Christopher K.
