XML -2- HTML Transformer Factory Configuration Error

[Rao Nadella]

When i call a servlet with the javax.xml.transform.Transformer API's, I get the following error.
Servlet failed with exception javax.xml.transform.TransformerFactoryConfigurationError.
Provider for javax.xml.transform.TransformerFactory.newInstance(...) not found.
--------------
What do I need to set to make it work right?
Thanks a bunch

You probably don't have your XML parser in ur
WAS classpath .....

Rao,
See this article on how to set classpaths
in WAS 4.0.1AEs

Hi,
We're having a similar problem transforming XML with XSLs. We are using the Xalan and Xerces jars and these work fine on Weblogic. However when we have put these in the application's WEB-INF/lib directory they don't appear to being picked up? Is this because other instances of these jars exist elsewhere on WAS4.0? We had to remove the J2EE.jar from the WEB-INF/lib folder to get the application to run.
Other jar files we put in the WEB-INF/lib directory get picked up okay if they don't have an other version elsewhere in the WAS file system.
The exception I get is below.
Cheers,
Steve
