Actually, each VM has at least three classpaths, not counting any separate ones implemented in the Java program being executed (Tomcat in our case). These are the bootstrap, endorsed, and system paths, each with its own classloader. The only item necessary in the VM system classpath for Tomcat execution is the bootstrap.jar file from the bin directory. (The scripts distributed with 5.5.12 still add tools.jar to the system classpath, although that's not needed anymore.) AFAIK, all other non-JRE classes used by Tomcat are indeed loaded by custom class loaders that are part of Tomcat. > I am probably totally wrong, but isn't the BASEDIR variable in > setclasspath.sh defined from CATALINA_HOME?

Yes, endorsed libraries are considered extensions of the JRE, not of the Java program, and it is therefore appropriate to have just one copy of them per installed JVM. All other classes in the common directory tree are considered to be extensions of Tomcat, and are thus usable by all Tomcat instances referenced by a given CATALINA_HOME. > However, it probably has nothing to do with the original question of > this thread, so I better stop spamming :-) Both of us should, I suspect, but somebody's got to keep the list server from going to sleep... - Chuck THIS COMMUNICATION MAY CONTAIN CONFIDENTIAL AND/OR OTHERWISE PROPRIETARY MATERIAL and is thus for use only by the intended recipient.
