--------------------------------------------------------------
Hi All,
I am trying to create an asset (.txt file ) in GUVNOR through REST API in JAVA. But the problem is when using the post method to create asset .. program is executing with no error but i am having SERVER_ERROR(http 500  error..) as a response. 
Steps I followed :-
1.Created an asset named SayanFileTest2.Got the Asset Info in Atom -XML format .. 
3.Replaced the asset name With new one (FileUploadTest1)
4.Called the post method to create a new entry in GUVNOR.

Can anybody please help me with this one?  I am providing the code.. Please tell me what i am doing wrong in this and how to solve it. 
(N.B. - I am using jboss-as-7.1.1.Final and drools-guvnor 5.3.0)
