xCP 2.1 Java Service Execution

Hi all,

I've created my first Java Service in xCP from the bits and pieces that I could gather from the web and forums. I'm suprised there's not a guide or an update in the developer's guide since version 2.1 of xCP cause it looks to me everyone is having issues with it. Well, here are my questions that I hope someone has gone across and can help future requests:

1st. How are you suposed to define the arrays for the input/output parameters? The only one that seems to work is String[] (still not able to debug or run) but I've decompiled code and saw List (without the type definition)....

2nd. After the JVM version issue everyone has faced (and is not logged anywhere) I've got to the point where it cann't execute the module with the message:


com.documentum.bps.ServiceDefinitionConfigError: Could not resolve bof module name in invoke java-service service definition
  at com.documentum.bpm.engine.utils.ServiceDefinitionResolverUtils.resolveInvokeJavaServiceDef(ServiceDefinitionResolverUtils.java:94)

Installing the application (and the module) has taken me to the next Stack trace. I've checked the cache and it isn't obviously there. Any suggestions?

What is the name of the module in the repository? Sometimes it can be converted to lowercase which can cause problems. In the past I have had to rename the module that was deployed.

Hi, The weirdest thing happened. I changed the java library artifact to lowercase letters and got the error because it was trying to retrieve a module with the first letter of each word in capital letters.

I cleaned the cache, deleted old modules (that weren't removed by the xCP deployment) and created a helloworld method in my class and was able to invoke it.

The NullPointerException will occur on execution time when setting an Array for the input parameters (as a String[] in the class).

How can these be set in the class?

Rename all the Array for the input parameters (as a String[] in the class) name from camelCase to underscore. For example change the name of sZipObjectType to s_zip_object_type.

For me it worked in this way. Try hopefully it will get solved.
