Hi All,
I am trying to deploy Apache AXIS 1.2 RC2 as Web Module inside a EAR deployed using WSAD 5.1.2's WebSphere 5.0
Test Environment.
Websphere 5.0 server has built with its own logging component internally for its own logging purposes and has been kept in Webphere
java runtime extension folder. So whenever that logging component has been called by default the logger and manager has been loaded from the extension class loader. We need to avoid this scenario for our own applications deployed on WAS 5.0 that use the same logging component inside our EAR. Otherwise we could not possible to load application specific loggers� properties files. So in order to achieve this, the ear file
class loading policy should be kept as PARENT_LAST. So the application will able to locate and load our logging component files from Shared libraries then will try to load other classes from extension class loader. Otherwise jlog framework
will not work.
So the settings that work for our logging component and do not work for AXIS Web Module integration into the same EAR are below:
a.ear Classloader mode: PARENT_LAST (must)
b.ear WAR classloader policy: APPLICATION
c.war Classloader mode : PARENT_LAST or PARENT_FIRST (can be anything)
WebSphere 5.0 exception stack trace

One point to note is that the settings that do not work for our logging component and work for AXIS Web Module integration into the same EAR are below and I am not sure why these settings work:
a.ear Classloader mode: PARENT_FIRST (must)
b.ear WAR classloader policy: APPLICATION
c.war Classloader mode : PARENT_LAST or PARENT_FIRST (can be anything)
Now can anyone please tell me how do I avoid above errors.
Thanks & Regards,
