SOLUTION
========
1. Increase Max message size from WLS console
a) Login to “weblogic console url” as weblogic admin user
b) WebLogic Console -> Servers -> Admin Server -> Protocols -> General -> Max Message Size
Increase Max Message Size to 20000000 (Any value higher than Incoming message size in error message)
2.Restart Middle Tier Services
