Thanks!  That's what I was missing.

I've got everything running, but having problems with new objects being
created unexpectedly...

I'm using your code as follows:

private Scriptable prepareExecScope(Scriptable sharedScope, Handler
client)
throws EvaluatorException, JavaScriptException, IllegalAccessException,
InstantiationException, InvocationTargetException,
ClassDefinitionException, PropertyException
{
Context cx = Context.enter();
try
{
Scriptable scope = cx.newObject(sharedScope);

scope.setPrototype(sharedScope);
scope.setParentScope(null);

ScriptableObject.defineClass(scope, MFPHandler.class);
Scriptable jsClient = cx.newObject(scope, "MFPClient");
scope.put("client", scope, jsClient);

return scope;
}
finally
{
Context.exit();
}
}

The problem comes when I call the ScriptTest - I am passing in an
MFPClient object that I have already instantiated, and want to use
that, with it's member variables, with this particular script
execution.

However I see the MFPClient constructor getting called twice more, with
the ScriptableObject.defineClass, and cx.newObject(scope, "MFPClient")
calls.  Thus the script calls an object that has none of the member
variables set.

Is there any way to have the script call an pre-instantiated java
object, which has particular member variables before the script is run.
Many thanks,

David
