Hi,
I tried with both Unmarshall static and non-static methods. Still I am
facing the same issue while trying to convert xml to java object.
Here are my code snippets and find attached files for rest class files. I
tried with Castor generated mapping file and hand written mapping file. I
didnt see any difference in the output.
When I tried without mapping file, I am seeing Null Pointer Exception when I
tried to get values with getter method.
Please help me either ways. I got struck with this problem for 3 days.
