Yes they are.  It is the Java compiler that we need, so that JSP pages can be
compiled, and that is in the classes.zip file in a JDK 1.1 release.

Note also that adding the tools.jar file to the classpath, even when it doesn't
exist (as it won't in a JDK 1.1 environment) does no harm, because the entry is
silently ignored.

At present there are no functionality differences in Tomcat itself depending on
which platform you run it under.  In the future this might change --
particularly with respect to some differences in security managers and class
loaders between the two JVM versions.
