It appears that you have an earlier version of the DOM on your classpath in
front of xalan and xerces. If you are running on JDK 1.3, see
http://xml.apache.org/xalan-j/faq.html#faq-6.

Subject:  XPath query throws NoSuchMethodError Exception

Hi

I have a big problem, running any XPath expression. If I run a expression
like this:

NodeList nodes = XPathAPI.selectNodeList(root, "data");

I get the following:

java.lang.NoSuchMethodError
at org.apache.xpath.DOM2Helper.getNamespaceOfNode(DOM2Helper.java:348)

I am using the lastest Xalan 2.0.1 release, and Java 1.3 (JBuilder 4.0)

I get the same error when using the selectSingleNode method.

Any Ideas...

Thanks
