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

Temporary fix
