Subject RE: xsltc w/ 2.0.3
Date Wed, 23 Oct 2002 16:10:23 GMT
I (religiously) use the stock 2.0.3 jars.

I definitely had to make some changes in my xslt, because of bugs in my
code that xsltc uncovered, but also (I think) because of bugs in xsltc.
(Actually, even though I got my app to run under xsltc, I'm considering
switching to Saxon because of the quirks in xsltc--for example I can't
get xsltc variables to hold a temporary tree).

I think it is important to clear out your tomcat work directory, and to
start with simple transforms and work your way up.  Expect to do some
debugging.
