newbie about struts and databases
hi, i'm starting in Struts, and am reading the tutorials in the struts site about building applications with it, and i was thinking if there is any easy tutorial about database access using struts, so i can start more rapidly with it (and my boss doesn't get mad at me while convincing him to use struts in the new project we are starting ;) thanks in advance, and best wishes -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]
RE: newbie about struts and databases
Allow me. That's a pretty involved question. The best thing you can do for yourself as a beginner is pick up a copy of Struts in Action so you can have some background on the technology and how it should work. If you are new to Java and JSP, I can recommend the WROX Press book JSP Web Development, which gives a good overview of Java, JSP, Struts, and also gives a simple example application that shows how these technologies work together. Both of these books address the subject of database access. -= J -Original Message- From: miguel angel rojas aquino [mailto:[EMAIL PROTECTED]] Sent: Tuesday, January 07, 2003 3:59 PM To: [EMAIL PROTECTED] Subject: newbie about struts and databases hi, i'm starting in Struts, and am reading the tutorials in the struts site about building applications with it, and i was thinking if there is any easy tutorial about database access using struts, so i can start more rapidly with it (and my boss doesn't get mad at me while convincing him to use struts in the new project we are starting ;) thanks in advance, and best wishes -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED] -- To unsubscribe, e-mail: mailto:[EMAIL PROTECTED] For additional commands, e-mail: mailto:[EMAIL PROTECTED]

Your data access solution shouldn't have anything to do with Struts. It should be usable from a Struts Action, from a Swing app, from a console app, etc. Personally, I implemented the Data Access Object pattern as shown in the J2EE Blueprints document. That may be overkill for a simple app where you might put JDBC code directly in the Action class. Or something in between. The problem with the existing examples is that they have comments such as, In a real-world application, we wouldn't do this, but for the purposes of this example... And nobody ever shows you how you WOULD do it in the real world, because it's messy and complicated and depends on your data structures and rules. So if you haven't determined how you're going to access your database, do that first, separately, before you try to access your database from Struts. -- Wendy Smoak Applications Systems Analyst, Sr. Arizona State University PA Information Resources Management
RE: newbie about struts and databases
In regards to Wendy's statement: That may be overkill for a simple app where you might put JDBC code directly in the Action class. Simple Applications Grow into Five Headed Monsters: I just wanted to agree with Wendy and encourage the use of DAO or some sort of separated database access (DAO,OJB,etc...) even in simple applications. I develop websites for small to mid-sized businesses. I made the Struts newbie mistake of placing all my logic/database access in my action classes. As my simple applications grew I began to see how much I was tying myself down by making my Actions synonymous with my logic. To make a long story short. I had a bunch of code buried in my Action classes that ultimately needed to be shared amongst several web-apps running on the same server. Early on I had seen the growing complexity of my simple applications and I began using the DAO pattern to seperate out my database access (along with implementing some other clever patterns I picked up round these newsgroups). In the end I had to take two large chunks of code out of one of my webapps so that I could share it with several other webapps. I wrote a couple of main classes that read in some configuration files to perfrom automated data retrieval with my DAO/logic classes, set up a cron job and wham-o no painful translation from Action to standalone classes just the sweet ease of a pattern gone well. In the end... try to follow the pattern even if it seems overkill... cuz it has a higher probability of pay off when your app grows a few more heads than you expected. :-D I think we all know that story.
