WSO2 ESB If Then Else, authenticate or Error

Question

This may be a basic question, I am just getting used to the WSO2 lingo. I have two services that I can deploy independently with WSDLs and pass the proper SOAP request, and return information accordingly. Now I want to combine them into an 'If then, else' statement sort of deal. This would be set up in a sequence of some sort I believe, just not sure how with the filters.

Send in request with authentication request and info request
Do authentication request – continue if passes, 401 on failure
Do info request – get info
Return the info

If you have a sample I could follow or point me to one of the hundreds WSO2 has, I just haven't been able to pull much from them. XML source example for the config could work also. Thanks for the help, and for my ignorance of WSO2 lingo, and workflow.

You can have a look at filter mediator to filter messages based on conditions Entitlement Mediator. You can find samples here as a reference which will be helpful for your use case.

Thanks for the response Shelan. I'll look into the mediators and return back with guidance for other new users. – bbotz Sep 14 '12 at 14:59

So I ended up with something very similar to this. If someone down the road comes across this and looking for the wso2 configurations.
