| <subsection name="Objective"> |
| <p> |
| Demonstrate how to access various methods on the Synapse MessageContext API |
| using the script mediator |
| </p> |
| </subsection> |
| <subsection name="Pre-requisites"> |
| <p> |
| <ul> |
| <li> |
| Start Synapse using the configuration numbered 352 (repository/conf/sample/synapse_sample_352.xml) |
| <div class="command"> |
| Unix/Linux: sh synapse.sh -sample 352<br/> |
| Windows: synapse.bat -sample 352 |
| </div> |
| </li> |
| </ul> |
| </p> |
| </subsection> |
| <subsection name="Executing the Client"> |
| <p> |
| This example shows how an inline JavaScript can access the Synapse message context |
| API to set its 'To' EPR and to set a custom property to mark it as a response. Execute |
| the stock quote client, and you will receive the response '99.9' as the last sale |
| price as per the above script. |
| </p> |
| <div class="command">ant stockquote -Daddurl=http://localhost:9000/services/SimpleStockQuoteService -Dtrpurl=http://localhost:8280/</div> |
| <p> |
| Note that the symbol 'mc' is bound to the Synapse MessageContext object by the |
| script mediator. Then the user can invoke various methods on the message context |
| using common JavaScript syntax such as mc.getProperty('name') and mc.setTo('epr'). |
