Problem may be with saaj.jar and AXIS,WAS,WSAD

Question

Hi,
I have successfully developed and deployed an EJB using WSAD 5.1.2's WebSphere 5.0 Test Environment. I have even able to access the EJB using UTC(Universal Test Client) in WSAD and by launching the j2ee client module using
WebSphere lauchClient program.
Basically I have below directory structure:
a.ear
--|-----axis.war
-----------|------ lib
--------------------|--- all axis related jars are here
--|-----demoEjb.jar (has java jar dependencies set to axis.war\lib jars
I have now exposed this ejb as web service using AXIS 1.2 RC2 deployed as web module inside WSAD. This web service is properly exposed as web service as I can see it and access its wsdl when I access axis web services.
Now I have written a standalone-outside-wsad web service client that uses AXIS stubs and when I try to consume to this ejb web service I am getting below error.

I read somewhere with axis mailing lists that it is problem related to axis's saaj.jar and wsad's websphere 5.0
test environment's webservices.jar so I even replaced my wsad installation's D:\Program Files\IBM\WebSphere Studio\Application Developer\v5.1.2\runtimes\base_v5\lib\webservices.jar with
saaj.jar but this did not help and even I have added an references to saaj.jar usign wsad's websphere 5.0 test environment
environment tab->ws.ext.dirs property and even this did not help.
Can anyone please tell me why is error occurring and how to solve it ?
Thanks & Regards,
Kumar.

Answer 1

Yes :-)
At the ear level, set the Classloader mode to PARENT_FIRST and WAR classloader policy to APPLICATION. At the axis web module level, set the Classloader mode to PARENT_LAST
