You might also look at the 'Core J2EE Patterns' book (also now online at sun) and look at the 'Service Locator' pattern. (This assumes the DB is registered with a central registry, as it usually is.) Most of the book's examples are about EJB (ugh), but there is a good example there of setting up access to a database with good architecture. They have sample code (example 7.8) which you can probably use with almost no modification. They also have some good advice there about separating Data Access code from the rest of your app.
What you need to keep in mind is that these things are not really different in Struts than in another programming mode. Struts only wires thing together for you, and the way you design your app and the code you write isn't that much dependent on the framework (or at least, it shouldn't be). So you need to learn the framework, but more important, you need to know the fundamentals of how to design your app so that it has the least dependence on the framework. When you build a house, it shouldn't matter what kind of vacuum cleaner you use. In the same way, when you build an application, it shouldn't matter too much what the provider framework is. The framework just provides services which you app can use. But if that service was not available thru the framework, you could get it some other way, and then the *use* of that service wouldn't have to change. Look at Struts as a big bag of nice services you can use, and then your app uses those services. If you went to another service provider, not everything would have to change. If it does, then that is an indication that your architecture doesn't properly separate concerns. Of course, all that is 'theory', and implementation always has to make compromises. But it helps to keep it in mind as an ideal. - Ray Clough > ----- Original Message ----- > From: "Nuwan Chandrasoma" <[EMAIL PROTECTED]> > To: "Struts Users Mailing List" <user@struts.apache.org> > Subject: Re: Spring tutorial > Date: Mon, 24 Sep 2007 00:16:03 +0530 > > > Hi, > > you can use the same approach you used in servlets. if you use > spring it will help you write the code in more elegant way :) > > Thanks, > > Nuwan > > rama krishna yalagandula wrote: > > Yes...
