Error Handling in OS 10gR3: How To's, Approaches, best practices

Question

I am trying to do error rhandling within OSB 10gR3 and looking for some guidance as to best practices and how to carry out the error handling based on my use-case as -
Consumers ---> GenericProxyExt(WSDL based) ---> GenericProxyInt(Any SOAP) ---> Proxy (Any XML) ---> Business Service --------------> Target Service
Since target web service will pass error in the SOAP:fault, where in the OSB should this error be handled? Also, how can I pass the custom error messages (instead of the one returned from the target service). Do I have to write error handlers in each of the proxy services?
Any insight, sample code, approaches will be helpful
Thanks,

Since BS throws soap fault, and the last Proxy is AnyXML. You need to do bit of manipulations. First of all for AnyXML services, you have to manually copy $fault into $body. Reason behind this step, is For Any XML there is no concept of $fault being returned and reply with failure. Subsequent proxies will receive the $fault as originated in Target Service. If we want to control the $fault received by the consumers, we have to use error handlers and populate $fault accordingly.
