[jdom-interest] Problems with Transform

Can't help you on the stream buffer stuff, but may be able to
help on the sample transforms if you are talking about

Sample session that works for me:

$ cd jdom/samples
$ CLASSPATH=./:../lib/xalan.jar:../build/jdom.jar:../lib/crimson.jar
$ export CLASSPATH
$ javac XSLTransform.java
$ java XSLTransform catalog.xml catalog.xsl
<?xml version="1.0" encoding="UTF-8"?>

So "String stylesheet" is the path to the .xsl file, the transformation
itself is done by Xalan so that does need to be on your CLASSPATH, and
I'm not using NetBeans so don't know if that is relevant or not.

Hope this helps.
