APAR status

• Closed as program error.

Error description

• DataPower might send errors to the client
  when a Web Service Proxy is configured with one-way
  operations. This might result in the client receiving
  an unexpected response.
  

Local fix

• Chain all requests to the Web Service Proxy through a MPGW:
  - with pass-thru request type
  - with static backend http://127.0.0.1:xxxx (the port of the
  WSP)
  - with propagate URI on (this is dedault)
  - with SOAP response type
  - with Server-to-Client rule:  match(uri=*)
  NULL--RESULT--OUTPUT
  
  Sending requests through this MPGW will eliminate any response
  
  received from Web Service Proxy, such as an error message
  response.
  

Problem summary

• Affected is the use of a Web Service Proxy or Multi-Protocol
  Gateway in one-way mode.
  
  If an error occurs processing a request, the error
  response might be incorrectly sent to the client.
  
  
  Please note that DataPower implementation of one-way (for
  complete MPGW, the one-way operations of a WSP) is to make
  response pass-through. This has three consequences:
  1) A configured response rule will not get executed in case of
  one-way processing
  2) If a backend (incorrectly) returns "something" that will
  just be returned by DataPower as well (because of pass-through).
  The backend needs to be fixed to not break the one-way contract.
  3) For HTTP protocol, the HTTP response body will be empty, but
  the HTTP response headers will be returned to client (allowing
  to access eg. HTTP response code).
  

Problem conclusion

• Fix is available in 5.0.0.10 and 6.0.0.2
