[xsl] run time error "TransformerFactoryConfigurationError"

[Yongxia Yan <yyan@xxxxxxxxx>]

All,

I am newbie to xml and tried to run the examples on apache site. I installed the following jars to my box:
xalan.jar/xml-apis.jar/xercesImpl.jar and set my classpath according. The compile is ok, but got a run time error.

Any idea?

Thanks.

Yongxia
