Method Detail

getInvoker

public static Invoker getInvoker()
                          throws java.lang.Exception

Returns:

the correct invoker to use in the app.

Throws:

java.lang.Exception

getRemoteInvoker

public static Invoker getRemoteInvoker()
                                throws java.lang.Exception

This should be used by objects that are separated by a remote boundary. You should also recognize that the parameters passed into a remote call will be passed by value and not by reference. In the case of a module invocation this means that the CoefficientContext that is sent across and modified will not be modified by reference. Therefore you should set your reference to the context to the returned value so that all changes will be propagated back across the remote boundary.

Throws:

java.lang.Exception

init

private static void init()

initProperties

private static void initProperties()
