Example of using Mule ESB to route web service calls

I'm looking for an example of how to set up a very simp开发者_如何学编程le Mule configuration to route a SOAP web service call from a client to a service provider. Initially, there will just be one provider, and then I will want to add multiple service providers and a round-robin routing strategy in Mule.

Most of the examples on the Mule site have the service provider running within the Mule container. I want mine to be completely external.

If you don't need to decompose message arguments use HTTP pass-through, which is more light-weight and a lot simpler. For the round-robin implementation you could use a filter router with a groovy-based filter expression.

See here:

Create pass through with Mule ESB 2.2.1
