websphere cxf factory 不兼容問題

If this is a record of possible occurences of this error then:

I just got this error on WAS (8.5.0.1), during the CXF (2.6.0) loading of the spring (3.1.1_release) configuration where a BeanInstantiationException rolled up a CXF ExtensionException, rolling up a IncompatibleClassChangeError. The following snippet shows the gist of the stack trace:

In this case, the solution was to change the classpath order of the module in my war file. That is, open up the war application in the WAS console under and select the client module(s). In the module configuration, set the class-loading to be "parent last".

This is found in the WAS console:

• Applicatoins -> Application Types -> WebSphere Enterprise Applications
• Click link representing your application (war)
• Click "Manage Modules" under "Modules" section
• Click link for the underlying module(s)
• Change "Class loader order" to be "(parent last)".
