SAX parser exception : Namespace not supported by SAX parser

Question

Hi,
I'm using xslt to transform xml to html. I've downloaded Xalan2J from Apache website and I've used Transformer factory implementation.
The code works fine through Forte IDE environment where I've mounted jar files xerces.jar, xml-apis.jar, xalan.jar
The problem occurs when I try to instantiate the same method through JSP page. It throws an exception
SAXParser exception : Namespace not supported by SAXParser. I'm trying to run the jsp file through jakarta tomcat environment.
I've included xerces.jar, xml-apis.jar, xalan.jar in my classpath. I fail to understand why namespace support is not available.
Any help/suggetsions would be appreciated :)
Thanks

Hi,
Yes, In tomcat environment, by default the jar files in the lib directory are set before reading the system classpath which causes a problem. One could replace the xerces.jar with a new jar file and delete parser.jar but that has its own set of problems.
The other alternative would be to use something like
System.setProperty("javax.xml.parsers.SAXParserFactory","org.apache.xerces.jaxp.SAXParserFactoryImpl");
This worked for me..:)
