The Switch and Send mediators of the ESB profile of WSO2 EI simulate the Message Router EIP. The Switch Mediator depicts the Router and observes the content of the message, while the Send Mediator sends the message to a selected recipient. Each case defined in the Switch mediator is used to decide the routing of the message to the appropriate service. fooOutQueue and barOutQueue act as two separate services. |
