Symptom

The web service provider application with overloaded methods deploys with warning:
‘java.lang.RuntimeException: Duplicate request/response wrapper beans found’
Other terms

overloaded web service operations
Reason and Prerequisites

The overloaded methods of web service are stored in a Hashtable with key the method name. As a result in case of overloaded method, only the last processed method information is stored and the information for the rest of the overloaded methods is lost.
As a solution the key is changed to use the method name and the method parameters as well. Thus the overloaded methods are properly processed.
Solution

Update to 7.11 SP03 or a subsequent SP.
