This sample contains three proxy services. The stockquote client invokes the LocalTransportProxy. Then the message will be sent to the SecondProxy and then it will be sent to the StockQuoteProxy. The StockQuoteProxy will invoke the backend service and return the response to the client. In this sample, the communication between proxy services are done through the Local transport. Since Local transport calls are in-JVM calls, it will reduce the time taken for the communication between proxy services.
1. Enable Non Blocking Local Transport /wiki/spaces/EI6xx/pages/49613810 for the ESB.
2. Create the above configuration and deploy it in the WSO2 EI profile, see Working with WSO2 Integration Studio.
