Re: Data-sources using struts:Tomcat's or NOT?
Thanks a lot for every one's immediate remark.I may have got it. And I find that the struts-doc-1.2.9 is of use for beginners as me.

The Struts DataSource manager should only be used with legacy business classes that don't provide their own connectivity. When possible, we strongly recommend use of the standard DAO pattern, so that the Action classes do not need to know anything about the persitence mechanism. The DataSource manager is being retained in Struts 1.x for backward compatibility but may not be retained in Struts 2.x or later. Also, by putting datasource definitions in JNDI it makes it very simple to change your connection parameters based on which server you're on; nice for development/staging/production environments.

As Craig pointed ou a few days or weeks? ago you should use Tomcat's. The Struts datasource was developed just because at that time it wasn't possible to configure a datasource in Tomcat. Tamas

I saw a comment earlier that the Struts data-source is deprecated and should not be used. - Original Message - From: "M.Liang Liu " <[EMAIL PROTECTED]> To: Sent: Thursday, April 20, 2006 9:45 PM Subject: Data-sources using struts:Tomcat's or NOT? I am a freshman to struts. And now I got a problem to make my decision which data-source should I choose. The point is as following: I created a project via myeclipse using Tomcat 5.5.X as the web server.Asa result,I can use the Tomcat data-source related to JNDI: Step1.define the Resource in the Server.xml under the folder %Tomcat_Home%\conf\ Step2.define the Resource-ref in the web.xml of the very project I created . And I find it works well. When I started to learn struts,I found that I can define the data-source in the struts-config.xml.What has confused me is that it is an absolutely new one different from Tomcat's.

Data-sources using struts:Tomcat's or NOT?
I am a freshman to struts. And now I got a problem to make my decision which data-source should I choose. The point is as following: I created a project via myeclipse using Tomcat 5.5.X as the web server.Asa result,I can use the Tomcat data-source related to JNDI: Step1.define the Resource in the Server.xml under the folder %Tomcat_Home%\conf\ Step2.define the Resource-ref in the web.xml of the very project I created . And I find it works well. When I started to learn struts,I found that I can define the data-source in the struts-config.xml.What has confused me is that it is an absolutely new one different from Tomcat's. My question is that: Which one is better namely more effective？Which one is deprecated?Or both are OK? Any pointers would be appreciated.
