Subject Getting the exception - definition mismatch between parent and child loaders
Date Thu, 09 Jul 2009 06:19:18 GMT
Hi All, 

I posted the below query in some forums and didnt get any response,
hence hoping to get a solution here.
 
We are using xmlbeans 2.4 in our project. 
Java version = J2RE 1.4.2 and websphere 5.1 

At runtime the xml doc gets created fine but when we use the xPath
functionality to edit the document, we get the following exception - 
 
javax.servlet.ServletException: Class javax/xml/transform/Source
violates loader constraints:  definition mismatch between parent and
child loaders

 .....
 
We also tried placing the xml beans related jars ahead in the class
path. 
I tested the functionality standalone using all the below mentioned jars
and there was no conflict. 

Does anyone have a solution to this? 
Any pointers in this regard will be greatly appreciated. 
 
Below are some of the jar files in the classpath of the project - 
 
xmlbeans-qname.jar  
xbean_xpath.jar  
xbean.jar  
saxon9-dom.jar
