ModuleLocalHomeImpl0_0 can not be casted to ModuleLocalHome or SModuleLo...

I created an XI Adapter Module as per the SAP examples and deployed it to an XI server. However I get the error:

java.lang.ClassCastException: class com.sap.aii.af.mp.module.ModuleLocalHomeImpl0_0 can not be casted to ModuleLocalHome or SModuleLocalHomern
tat com.sap.aii.af.mp.ejb.ModuleProcessorBean.process(ModuleProcessorBean.java:261)rn
tat com.sap.aii.af.mp.processor.ModuleProcessorLocalLocalObjectImpl0_0.process(ModuleProcessorLocalLocalObjectImpl0_0.java:103)rn
tat com.sap.aii.af.mp.soap.web.MessageServlet.callModuleProcessor(MessageServlet.java:174)rn

The Adapter Module Framework can not cast the interface classes to the expected class types. I am sure my EJB definitions are right because they follow the examples where I declare the Interfaces in the package com.sap.aii.af.mp.module. My EJB "implements SessionBean, Module" so where to the unexpected class types come from.

Has anyone had this same problem? Could it be a class not found problem or some other error that is not a really a Casting problem? Is the Adapter Module Framework broken?

Any help appreciated.

Thanks,

Doug

Check whether you have included all the jar files mentioned in the documentation.

Therefore the required libs aii_af_mp.jar and aii_af_ms_api.jar are in the ear. The module does nothing apart from add a Hello World attachment as per the examples.

I will try to set this up on a different XI server to see if the XI installation is the problem.

Thanks again,

Doug

The library files aii_af_mp.jar, aii_af_ms_api.jar and aii_af_trace.jar <b>must not</b> be inside the EAR. Delete them from the EAR file before deploying.

Thanks a lot guys.

The problem seams to be the handling of the libs which I do not fully understand. However I was missing the lib definitions in the file: application-j2ee-engine and also should not have been packing all the libs in the ear. (Why this produced a casting error I do not know.)

I now have a casting problem inside the process method:

Message msg = (Message) inputModuleData.getPrincipalData();

inputModuleData.getPrincipalData() returns a com.sap.aii.messaging.mo.MessageContext

but I can debug this easier, so I will close this issue.

Thanks again,

Doug
