[jdom-interest] java.lang.NoSuchMethodError when using tomcat

[Mark_Brown at aoncons.com]

I know this one.  I just had the same problem when trying to build jdom.  Jason
pointed out to me that a different version of DOM was being used (ie. DOM 1).
Check the path for your servlet engine.  It must be picking up a jar file from
jaxp or xml.jar or something other than the Xerces 1.2 jar file.

Subject:  [jdom-interest] java.lang.NoSuchMethodError when using tomcat



Hi all,

I have written an application that parses an XML-file using jdom and
DOMBuilder.
When I changed the application into a Servlet, I get the following error
Message when I try to build the document from the XML-file:


Error: 500
Location: /examples/servlet/ResponseCreator
Internal Servlet Error:

java.lang.NoSuchMethodError: org.w3c.dom.DocumentType: method

I have no clue what the error might be as the same code works fine when
run as an application.
I use jdom beta4 (tried beta5, too) and tomcat 3.1 embedded with apache
1.3.14.

Thanks for reading this, any help is appreciated.

Philipp
