Business delegate and action class

[kundan varma]

Hi Ilja,
If i am using struts framework, do i need business delegate or action class itself acts as business delegate and i should use only service locator pattern.
Thanks,
kundan

In our project, we have used a separate business delegate layer with the action class. By doing this, you can isolate the calling of remote methods against stubs and handling of remote exceptions to the delegates. But for performance, you can also have the action layer itself act as the business delegate. I feel there is no harm in this.In that case, you can have your action classes talk to the Service Locator directly. For performance reaons, I think the latter is better.

Sorry, I don't know Struts very well. I will move this to our Struts forum, where there are certainly a lot of experts who can help you...

It would also be great help, if someone can explain me what purpose does the Business Delegate layer server, apart from creating one more layer between my Servlets and EJBs.
