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....!!!!
