Re: problem with xalan-j in servlets (update)
more error follows.. seems like xalan is trying to use com.sun.xml.parser.SAXParserImpl... how can I
get it to use xerces???
I'm attaching my java code ..
Thanks
Charlie

Subject: problem with xalan-j in servlets
Hi all:
I've tried to battle this weird problem for 3 days and still can't figure it out.. please help!!
Basically I'm trying to convert an XML string to an HTML string via an XSL file.. the program runs fine from the
command line.. but fails if I run it as a servlet.. I've tried weblogic, jrun and java web server. same error..
I have the latest of xerces.jar (1.3, size is 787419).. and xalan.jar (size 702536).. and I've made
sure I put xalan.jar and xerces.jar at the very first of the appserver's CLASSPATH.. what could
I be missing here???
Thanks all
Charlie

Dom Input sample problem
Posted by mahesh <ma...@finessealliance.com>.
Hi
I compiled xalan c in solaris successfully. I was able to execute the samples given with source code.
I tried to use Dom Input to XSLT. I compiles and run well. but the output xml file I received is not correct, I could get the problem. Could you please tell me what is wrong.
The source code is
