I have the servlet below to use .....FormsService. I'm trying to create a unit test (see below) but I'm getting the following error. It's failing at line 33 of the servlet:
Document xmlDocument = new Document(xmlData.getBytes());
It seems that the servelt is not initialized correctly or messing the references. Can you please help?
