Prerequisites:

  • Deploy the SimpleStockQuoteService in sample Axis2 server and start it on port 9000.
  • Start ESB with the sample configuration 450 (i.e. wso2esb-samples -sn 450).

Invoke the client as follows.

ant stockquote -Dtrpurl=http://localhost:8280 -Daddurl=http://localhost:9000/soap/SimpleStockQuoteService

Note that the address URL of the client request contains the context 'soap'. But in the Axis2 server all the services are deployed under a context named 'services' by default. ESB will rewrite the To header of the request by replacing the 'soap' context with 'services. Hence the request will be delivered to the Axis2 server and the Axis2 client will receive a valid response.
