Pre-requisites
- Deploy the SimpleStockQuoteService in the sample Axis2 server and start Axis2
-
Start Synapse using the configuration numbered 151 (repository/conf/sample/synapse_sample_151.xml)
Unix/Linux: sh synapse.sh -sample 151
Windows: synapse.bat -sample 151
Executing the Client
This configuration creates two proxy services. The first proxy service 'StockQuoteProxy1' uses the sequence named 'proxy_1' to process incoming messages and the sequence named 'out' to process outgoing responses. The second proxy service, 'StockQuoteProxy2' is set to directly forward messages to the endpoint named 'proxy_2_endpoint' without any mediation.
You can send a stock quote request to each of these proxy services and receive the reply generated by the actual service hosted on the Axis2 server instance.
