Hi Experts,

I am getting the following error while executing the Java Service in a Stateless Process.

Thanks for your reply Lily, I got the error solved. The error was throwing from the Bean Class. There was strange error for Camel Case attributes. I changed the naming convention from Camel Case(attributeNames) to underscore (attribute_names). After changing this it stopped throwing nullPointerException.

Though it sounds strange but it is working....!!!!

The stateless process is executed on the xcp application server side.

You can turn on these trace in the application log4j to help you gather more information:

log4j.logger.com.emc.xcp.rest.core.process =DEBUG

log4j.logger.com.emc.xcp.services.process=DEBUG

log4j.logger.com.documentum.bps.bof=DEBUG
