We propose to add a new type of execution policy, which executes an arbitrary script in an available dynamic language in its accepts() method, and returns a boolean value.

We will build on the existing org.jppf.scripting framework already uysed in the admin console. Some default varibale bindings will be provided:

• the JPPFSystemInformation of the node being evaluated
• the server-side or client-side SLA and metadata of the job being matched
• the number of nodes to which the job is currently dispatched
• a snapshot of the server statistics

For now, the choice of languages is still limited to Groovy and JavaScript, however this should be easily expandable later on, by using an SPI-based discovery mechanism instead of the current script engine factory.
