Hi Virat,

if you haven't solved yet...

In theory, the NPE can come there only if the content is null. The content can be null if it gets a null value back during it's being read. Are you sure about that the service1.xml is on the right place?

Hi Zsigmond,

Thanks for your reply.
Yes.
I put service1.xml in the same location of service.xml 's default location defined by LDS

as well as i mentioned in service.xml as following code :

<service-builder-import file="service1.xml"/>

Hope,its correct.
Please correct me if i am wrong.

Hi Virat,

have you tried to debug what is the problem? I think, that would be the most efficient way.
