Not well-formed request to ALSB

Question

I want to send not well-formed request to AquaLogic Service Bus and to get user-friendly error message. When I send request where one namespace is not defined, for example:
<SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<SOAP-ENV:Header/>
<SOAP-ENV:Body>
<m:GetMessage xmlns:m="http://local.com/schemas/msg" >
<m0:InputData>
<m0:FirstName>Nicole</m0:FirstName>
<m0:LastName>Richie</m0:LastName>
</m0:InputData>
</m:GetMessage>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>
ALSB throws fault message with:
- errorCode: BEA-382513 and
- reason: ALSB Replace action failed updating variable "body": javax.xml.stream.XMLStreamException: Prefix m0 used without binding it to a namespace URI
I managed to get user-friendly error message with two proxy service where:
- Proxy service “A” calls the proxy service “B”. In Route Error Handler of proxy service “A” checks if proxy service “B” throws the BEA’s error message and changes it in to error message that I want. Service Type of proxy service “A” is WSDL Web Service.
- Proxy service “B” have some logics and calls the real business service. Service type of proxy service “B” is any SOAP Service
Is this good solution in terms of the overall load on the system?
Also, is there any other solution to get user-friendly error message from ALSB proxy service? Is it possible to make this with only one proxy service?

I would do it like this:
At the start of your proxy service add a "Validate" action. In the action's properties you can choose what to do when an error occurs (you can either save the error message to a variable or raise the error). Leave the default option "raise error". Add an exception handler to your proxy service and add the desired logic to change the error message into something else.
Hope that helps.
