Manu T George commented on GERONIMO-3894:
-----------------------------------------
Have you tried using hidden-classes to hide the conflicting classes in the
parent classloaders? JDOM is shipped with G. So by default the JDOM jar loaded
will be from the parent classloader and will not pick up the jaxen jar in your
application. Try hiding org.jdom and org.jaxen as I understand you package both
in your application
> java.lang.NoClassDefFoundError: org/jdom/Parent using JDOM 1.0

> URL: https://issues.apache.org/jira/browse/GERONIMO-3894
> Project: Geronimo
> Issue Type: Bug
> Security Level: public(Regular issues)
> Components: core, webservices
> Affects Versions: 2.0.1
> Environment: OS : windows 2003
> Reporter: Jean-Jacques Parent
>
> We've got a problem using jDOM 1.0 with geronimo 2.0.1.
> Just using the following method : XPath.newInstance(String) we encounter the
> following error message.
>
> Caused by: java.lang.NoClassDefFoundError: org/jdom/Parent
> at org.jaxen.jdom.JDOMXPath.(JDOMXPath.java:91)
> at org.jdom.xpath.JaxenXPath.setXPath(JaxenXPath.java:281)

> at java.lang.reflect.Constructor.newInstance(Constructor.java:494)
> at org.jdom.xpath.XPath.newInstance(XPath.java:137)
>
> The class Parent is present in the jdom jar which is located in the lib
> directory of our web application. (Such as the jaxen beta 9 jar)
>
> We have seen on JIRA that there is a similar problem :
> AXIS2-3413 : Cannot use JDOM within Axis2 (java.lang.NoClassDefFoundError:
> org/jdom/Parent)
> But don't really understand which solution is to be applied.
> There is obviously a conflict with jaxen jar but what should we do exactly?
