Deployment fails during stub generation

[Former Member]

Hi all,

I am currently migrating a J2EE application from WLS to SAP NW 6.40. After solving a couple of issues

with my DDs, I am currently on a halt concerning the following stack trace. It occurs during deployment

with the SDM.

Caught exception during application deployment from SAP J2EE Engine's deploy service:
java.rmi.RemoteException: Cannot deploy application myCompany.com/myApp..

Unfortunately, I cannot examine the generated stub because the temporary deployment directory has been

cleaned up when this Exception occurs. Did anybody happen to run into a similar problem during

migration?

Ok, some news. I found the setting for SDM to keep deployed files on failure and was able to take a look at the problem. It's no wonder that I can't deploy because the generated stub is simply uncompilable.

The objects inn and outt used for the method call are simply not generated by the SAP generator, therefore the compilation error.

Hi,

for everybody who is interested. I figured out what the problem is. The method in the remote interface to be generated takes a java.lang.StringBuffer argument. The SAP generator seems to have problems generating source for methods with this object as argument. I changed the method signature from StringBuffer to Object and it works.

StringBuffer is supposed to work because it is an IIOP/RMI compatible object.

Marcel
