Getting NullPointerException from Service class #420

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
What steps will reproduce the problem?
1. I wrote a wrapper/client to access provisioning API's of gdata-java-
   client, just like the sample that this sdk provided. 
2. I used the above mentioned client to write a TDI(Tivoli Directory 
   Integrator) connector, which is again another class internally calling 
   the methods exposed by the wrapper mentioned above.
3. And I am getting a null pointer exception when the wrapper tries to 
   create and instance of UserService class. It works if i call these 
   API's directly from eclipse, but under TDI runtime, it fails with the 
   below exception:

What is the expected output? What do you see instead?
I should be able to successfully create an instance of UserService class. 

What version of the product are you using? On what operating system?
gdata client library version :  1.47.1
OS                           :  win 2k3 Enterprise x64

Please provide any additional information below.
