Hi Minal
I'm CC'ing the dom4j-dev list just in case anyone
else gets this problem too.
Which version of dom4j are you using? And is
dom4j.jar in your WEB-INF/lib directory?

Hi James,
Its Minal once again.This time my query is
regarding XPath.
My Servlet application is as
follows:-
1) I accept inputs from the user to insert the
values into an xml file which i use to store my data in.
2) Before inserting the data i need to check if
the data already exists in the file.I want to use XPath to reach the
particular node which holds my content.
3)The problem that I am facing is that the XPath
function-selectSingleNode(Object obj) works absolutely fine in a
Standalone application.However within
Servlets the usage of this function generates this exception: -
java.lang.Class: method
forName(Ljava/lang/String;ZLjava/lang/ClassLoader;)Ljava/lang/Class; not found
java.lang.NoSuchMethodError: java.lang.Class: method
forName(Ljava/lang/String;ZLjava/lang/ClassLoader;)Ljava/lang/Class; not

My code piece :-
Element
root=document.getRootElement();
DefaultXPath path=new
DefaultXPath("/Content");
Node
noo=path.selectSingleNode(root);
The above piece works fine within a
standalone.
Where could I be going wrong?
Please help.
Thanx,
Minal
