Hi,
this exception means that you try to extend a class from a sealed jar file.
For example the crimson.jar is a sealed jar file which contains the w3c.org
interfaces. So if you are instanciate a class which is not in the crimson
jar but implements one of these interfaces you are getting this exception.
Solution:
delete these interfaces from the jar file or use only one jar file which
contains a xml-parser.
Mit freundlichen Gr��en / best regards

Hi,
I've got a problem running a servlet on tomcat 3.2. I'm trying to tranform
an xml document with xslt to an html document. As an application it runs
wonderful, but I tried it with a servlet an all I see is the exception
below. The classes are all in my classpath...
Has anyone an idea how to solve the problem?
The source code where the exception is thrown:
TransformerFactory tFactory = TransformerFactory.newInstance();
Error: 500 Location: /servlet/xmlforumtests.TransformerServletInternal
