How to handle network connection error to bussiness service on OSB

Question

Hello everyone.
Thank for your attentions. I need some help for error handling in OSB 11g. I have a proxy service that route to a business service to check profile status. I'm using java client to consume proxy service and return result to customers. The problem that I'm face to is the handling network connection fail.
I want to get some message (or any useful information) from proxy service to report that connection to Business service is unavailable when that connection fail. I tried to add Error Handling but I cannot found that action from option list.
Can you review my proxy service and tell me some resolutions?
Any suggestion is appreciated.
Thank in advance

Answer 1

you could add an error handler on the route-action in your proxy service.
in there you could investigate the $fault variable and for example check which BEA-... errorcode comes back.
then you can decide what to reply back..for example create your own soap-fault and set your own messages.
now the default $fault generated by the osb itself will get returned
http://www.xenta.nl/blog/2010/07/17/oracle-service-bus-11g-handling-soap-faults/
maybe that one helps you a bit
