See my response to the "ant won't compile" message.  Same story, at 
least partially.

Download sources for Xerces-J. Read README, which tells me I need the 
tools.  Download the tools.  Extract "in the same directory."  What does 
that mean? Read Ah, tools is in the Xerces directory. Do that. 
  Run sh jars. Result:

Total time: 13 seconds

Do I really have to do this with Xalan as well?  Java 5 ships with 
xerces as its parser, in place of crimson. That's in the incompatibility 
notes. It ships with xalan, and defaults to using xsltc. Also in the 
incompatibility notes.  (And xalan 2.7.0 has one reported bug that I 
know of that causes problems with netbeans 5.0).

The simple fact is that I can pick up any of the binaries and they will 
almost certainly run without problems.  There are a handful of obscure 
binary-level incompatibilities, but the only problem I have encountered 
is the netbeans bug I mentioned; not an incompatibility.
