Class ScriptPoolFactory

java.lang.Object
  com.ca.jcs.processor.script.ScriptPoolFactory

All Implemented Interfaces:

PoolableObjectFactory

public class ScriptPoolFactory
extends Object
implements PoolableObjectFactory

Acts as the factory creating scripting engine instances based on the requested language, script and whether the script is going to be executed in its entirety or instead have functions defined within it called.

Note that this class ensures that any JavaScript EngineFactory added on the classpath is used in preference to the Rhino 1.6R2 JavaScript implementation bundled with JDK 6, because the bundled implementation:

1. doesn't allowing unwrapping of exceptions thrown by a script and
2. doesn't support compilation.
