Hello, two comments/questions: - in my opinion, sorting data is somehow business processing. Suppose that you have a long list of results that is paged (ie. retrieved in chunks from the data store). Sorting the data using a different criteria may involve re-accessing the data store to retrieve a different page of data.. and this should not be handled by a JSP. All this to say that I personally see the sorting/resorting in the Action/Model layers.
- I've seen a few messages related to using a business delegate to call an EJB. Isn't an EJB a Business Delegate itself? In my case, the EJBs are relatively simple for now, only things like UserEJB.create(UserValueObject) and similar. And I'm calling them directly from my Actions (using a ServiceLocator). I'm not sure I see the advantage of using both a Business Delegate and an EJB... aren't EJBs "better" in the sense that the app server supports/provides many more services (transactions, object pooling, security, ...)?

Hi Abhishek, My previous answer was a bit vague as it depends on the specific context. If for example you whished to check that the users details had been fetched before accessing a page then a taglib that uses a business delegate to access an ejb would be a good choice. If however you wanted to process the user's details, an action would be a better choice (indeed form submits should clearly be handled by an action). Some choices are not so clear cut. Sorting a table for instance could be handled by a taglib or a repost to an action that sorts and forwards back to the jsp. I guess I would favor the taglib option here, as I might (heaven forbid) use a framework other than struts in the future.

Thanks for your reply, There is a debate in my team these days on the use of Jsp Tags versus Actions. Some jsp developers feel that ejbs should be accessed via tag libraries, databases should be accessed via tag libraries and for simple rendering things like sorting a table jsp tag libraries should be used. While others like to use Actions for all the things mentioned above. Is there a document somewhere which describes what tasks are better suited for actions and what tasks are better suited for tag libraries. Technically, things mentioned above can be done easily by either as action or as jsp tags.But I want to make a consistent decision through out the application. regards, Abhishek.
