In respect to ejb-access there have been thread's around in this mailing-list (search for ejb in the archive).
And there is no difference between database-tables, corba-services and ejb's: they all belong to the applications backend. Therefor isolating them from the presentations layer is "good style". You can also use the catalog again (no jsp-links): If a jsp just uses a few ejb's then it is very probable to link to itself... I usually try to convince programmers to isolate the ejb's in their own server (use a pure application server) and have the presentation layer also in its own server (a pure servlet-engine). Normally that's when they accept, that ejb's are a backend-thing. hope this helps Alexander Jesse -----Original Message----- From: Abhishek Srivastava [mailto:[EMAIL PROTECTED]] Sent: Wednesday, December 05, 2001 1:00 PM To: 'Struts Users Mailing List' Subject: RE: Action an overkill ?? Ted's Catalog was useful in this regard as it clearly say no linking to jsps.... so no more sorting a table by jsp as it leads to a jsp making a hyperlink to itself rather than an action. Wish I could find something on the access of Ejbs via jsp-tags vs. Actions also. The feeling here is that use of Tag libraries is not mixing jsp code with business logic. instead it is regarded as a way or creating reusable code across jsp pages without mixing java with jsp code. which also appears to be true for Actions. The only issue seems to be which one should be used as a standard. Thanks a lot for your reply and help. regards, Abhishek. A ship in harbor is safe, but that is not what ships are built for. John A.
