Re: jstl x:parse outputs data

You'll need both Xerces and Xalan (Xerces should be included in the Xalan 
download). I believe the release notes for Standard 1.1 state that Xalan 
2.5 is required. Use this link:

http://www.apache.org/dyn/closer.cgi/xml/xalan-j

to download the latest version. If you run into any issues, you can try 
falling back to 2.5.0:

http://archive.apache.org/dist/xml/xalan-j/binaries/xalan-j_2_5_0-bin.zip

 From the ZIP file, you'll want the following JARs:

xalan.jar
xercesImpl.jar
xml-apis.jar

If you're using Tomcat, you can dump them in the common/endorsed dir. If 
you only have control over your own app, dump them in WEB-INF/lib.
