[Users] Communication between services

[Vincent Zurczak [via Petals ESB]]

Hi,

Your service cannot directly invoke a service.
Here is what you want to do:

myNewService( message1 ) {
    message2 = invokeService1( message1 );
    message3 = invokeService2( message2 );
    return message3;
}

Service1 and Service2 are your two services, imported in Petals through the
SOAP BC.
You can implement myNewService with EIP, as an example.
The routing slip should work if message1 matches the input of Service2.
If not, you should use the XSLT parameter, transform message1 to match what
Service2 expects and then send it. Routing-slip is suitable for this case
too, except you will consume 3 services instead of 2.
