Subject FW: org.apache.axiom.om.impl.llom.factory.OMLinkedListMetaFactory cannot be cast to org.apache.axiom.om.OMMetaFactory
Date Thu, 12 Jan 2012 14:50:59 GMT
Hi,

I have an Axis2 web service which allows values to be set then retrieved
using separate methods. This service works fine in the browser. This
service is using axis2 1.5.3 and axiom 1.2.10.

I then tried to run up a Java client (webClientBean, which is called
from a JSP page) using the same Axis2 library versions which
programmatically calls the service. Using the ServiceClient example at
the following page:

http://today.java.net/pub/a/today/2006/12/13/invoking-web-services-using
-apache-axis2.html 

I've created a client which is attached (webClientBean).

I get the following error in Tomcat when it is invoked:

org.apache.jasper.JasperException: java.lang.ClassCastException:
org.apache.axiom.om.impl.llom.factory.OMLinkedListMetaFactory cannot be
cast to org.apache.axiom.om.OMMetaFactory

Do you know what the problem is? I've had a look at the advice in
http://ws.apache.org/axiom/userguide/ch04.html with regard to Migrating
from older Axiom Versions, but I'm not sure if this is the problem, or
how to fix it.

Thanks,
John
