Setting up environment :
Setup both WSO2 AS and WSO2 ESB as mentioned in previous post.
- Create a proxy called EchoUTBasicProxy with following content.
- Enable Soap tracer on WSO2 AS.
- Enable wire log in WSO2 ESB.
- Invoke EchoUTBasicProxy using SOAP UI.
You can see, there is no username token in incoming message to backend. Instead you see basic auth header in outgoing message to backend from ESB.
