Objective: Introduction to Message Copying and Content Enriching with Enrich Mediator
-
Start the Synapse configuration numbered 15: i.e. synapse -sample 15
-
Start the Axis2 server and deploy the SimpleStockQuoteService if
not already done
Execute the client as follows.
ant stockquote -Dtrpurl=http://localhost:8280/services/StockQuote
This sample demonstrate the various capabilities of Enrich Mediator. Inside the in-sequence we store/copy different
parts of the message to properties and just before sending the message to the StockQuoteService, we modify the
request value based on the local entry value-init_req. Then in the out-sequence, the enrich mediator is used
to enrich a soap header based on the 'lastTradeTimestamp' value of the response.
