RTC Server side plugin : Getting illegal argument exception while creating work item

Hi,

I am trying to generate a new work item by using server side RTC api but I am getting the exception,

illegal argument exception

Below is my code snippet,

IWorkItemTemplateService iWorkItemTemplateService = getService(IWorkItemTemplateService.class);

IProjectAreaHandle projectAreaHandle = operation.getProcessArea().getProjectArea();

String[] strAtrray = new String[]{"AA","BB"};

int[] intArray =  iWorkItemTemplateService .instantiateTemplate("com.ibm.team.workitem.template2", strAtrray, projectAreaHandle);

Please correct me if I missed something.

A small piece of code would be helpful.I am trying to create a work item from existing template2
