org.w3c.dom.Node: method getNamespaceURI()Ljava/lang/String; not found

[Wolf-Dieter Klotz <kl...@esrf.fr>]

Is there anybody out there who can give me a hint?

I am using XALAN-J_2_0_0 and get the following error messgage when I try
to
create and/or traverse a DOM tree in a servlet:

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

My ClASSPATH includes:  xalan.jar, xerces.jar, bsf.jar from the
distribution and all the
Tomcat jar's.

Is there a problem with the org.apache.xpath.DOM2Helper module? I am
lost !!!
