Great example! Quick question - have you tried to deploy the app on WebLogic 9.2? I tried and it gives all kinds of errors (spring related). Packaging toplink_essentials_agent.jar in the .war does not help. Thanks,

Its a good thing to understand Spring.
But Im getting some problem. I didnt can execute this in Eclipse and Tomcat inside.
When Im using the war outside of Eclipse/Tomcat I got a error. It cannot find the MyDAOImpl.
I putted the springapp.jar inside the project build path, but this didnt works.
What more can I do??

See the build instructions in the zip. You need to build it with the full Spring 2.0 distribution available so that it can grab the necessary files to make the WAR (including spring.jar and the JPA, hsqldb jars etc.)

People, I made a conf in this project to build in Eclipse w/ Tomcat plugin and Oracle. I worked so hard to config this project. This thing happened because I dont know about Spring+JPA so much.
So, Im changing this project adding my things. This project that Im doing it just a page that had a form to make a search in the DB.
My question is just about the performace around this structure.
Anybody knows about it??

Very nice excample. But I’m having problems running it. I’ve build the war file running build.xml in eclipse, and deployed it on my TomCat 5.5.20 using the Tomcat Web Application Manager. It deploys successfully, but when I’m trying to open the webapp, I just get, The requested resource (/springjpa/) is not available. So I’m kind of stuck….any ideas?

thanx

It might not be /springjpa/. Please check the readme that accompanies the download. Also, Tomcat has a manager web-app that can tell you what is deployed where. Hope that helps.

I’ve finally got the example up and working now, but when I’m trying to access adduserform.jsp, I get the following error:

javax.servlet.ServletException: Neither Errors instance nor plain target object for bean name ‘user’ available as request attribute

I’m not sure what causes this.

Using this pattern, how do I map everything else then JSP files. Like graphics (JPG, GIFS etc..) When a jsp page contains urls to jpg files in tags, I get the following type of messages from Tomcat:

WARNING: No mapping for [/demotape/go/main/gfx/shadow_A_bottom.jpg] in DispatcherServlet with name ‘dispatch’
16.feb.2007 23:55:42 org.springframework.web.servlet.DispatcherServlet noHandlerFound

I’m kind of stuck on this, any help would be much apriciated…

Thanks for the tutorial. Is it possible to give an example where you configure multiple data sources for different transaction managers with different DAO object?

Thanks for this tutorial.

I succeded in deploying this application build with the ant script but not in Eclipse environnement …

Note: the parameters of the JVM are the same for Tomcat 5.5

Any idea ?
