[Opensource] xalan conflicts: xsl and jdk1.4.2

[larry hamel]

A caution to xsl developers: I just ran across a problem when upgrading to JDK 1.4.2, which contains an old version of Xalan. This old version, existing in rt.jar, can get in the way of the newer version of Xalan that ships with Expresso.

The specific error message I got was
        org.apache.xml.utils.WrappedRuntimeException: The output format must have a '{http://xml.apache.org/xalan}content-handler' property!

In theory, Tomcat class loaders should do the right thing and fetch classes only from the new jar in /lib, but tomcat 4.0.6 had this conflict. Reverting to JDK 1.3.1 solved the problem.
