public class: ScriptMediator [javadoc | source]

All Implemented Interfaces:

A Synapse mediator that calls a function in any scripting language supported by the BSF. The ScriptMediator supports scripts specified in-line or those loaded through a registry

   <script [key="entry-key"]
     [function="script-function-name"] language="javascript|groovy|ruby">
     (text | xml)?

The function is an optional attribute defining the name of the script function to call, if not specified it defaults to a function named 'mediate'. The function takes a single parameter which is the Synapse MessageContext. The function may return a boolean, if it does not then true is assumed.
