WebLogic 8.1.5.0 is shipped with an antiquated version of saaj.jar, Web services that are deployed on an Axis framework are known to fail due to this incompatibility. As a work around, an administrator can add a weblogic.xml deployment descriptor in the WEB-INF directory, this will set the flag <prefer-web-inf-classes> to true and cause WebLogic's saaj.jar to be overridden with the version bundled in the RPM Web services WAR file.
The following is an example of weblogic.xml:
<weblogic-web-app> <container-descriptor> <prefer-web-inf-classes>true</prefer-web-inf-classes>true> </container-descriptor> </weblogic-web-app>
This file must be deployed in the following directory: [rpm_web_services_directory]/WEB-INF
