Desicion pattern or smt ...

Hi

I am quite new to OO patterns, but I need this to be done and I don't know if there already is a design pattern for that problem.

So let me describe my problem. I have a JMS listener bean, lets call it JMSListener:

And there is a business object, that it must use:


Based on the content of the message, the JMSListener executes the methods in the BusinessService class. And the logic of what methods to execute, based on every case is stored in a datasource. For example like so:

Message|doThis|doThat
----------------------
case1 | x |
case2 | | x
case3 | |
case4 | x | x

So that is the problem and I want to do it intelligently
So if there is any neat design pattern for that case, please let me know.


Juhan.

I believe it is the mediator pattern. that helps me. If anyone have any suggestions, he is welcome to do so.
 
It is sorta covered in the JavaRanch Style Guide.
