SOAP UI--2.5.1:Not able to encrypt message using AES-256,RSA_OAEP_MGF1P

Hi Team,



I am trying to test encryption by creating java key store on my existing webservice using algorithm as AES-256, transport algorithm as RSA_OAEP_MGF1P. 

When i set the outbound security policies in SOAPUI with the configuration specified as above i am getting an error as given below:



        "WS-Security process failure:FAULT CODE: FailedCheck FAULT MESSAGE: The signature or decryption was invalid"



Please help me on the same!!.



Please find attached the setting's we have done on SOAPUI-2.5.1.
