Well can someone post an example for spring mvc using jdbcDaoSupport or simpleJdbc?. A web application where user can add, delete or update records in the database using spring mvc.

Thanks

Saurav, that might indeed be helpful. It would take quite a while to write it up though. The controller hierarchy alone is fairly complex, with dozens of methods that can be overridden in the various classes. You really have to take the Reference Documentation’s advice and thouroughly review the javadocs for the entire hierarchy…

hi bennett,
the article is great.
but i suppose the flow could be more easily understood if u could do a code walkthrough(just a basic one) with the same amount of explanation.
it would surely help anyone realise the concepts in a much better way.

Steve, one approach is this: don’t do the DB lookup in your controller’s action handler. Instead, add a ParameterMappingInterceptor to your handler mapping so the form parameters will be included in the render request as well. Then do the DB lookup in the controller’s render handler and return the data in the ModelAndView.

I’ve used this approach in my current project. It does mean that the DB query gets repeated with every render request though. If your DB query is especially heavyweight then you might need to do the query in the action handler and save the results in the portlet session.

Great post. I got a lot out of it.
OK, I’m having a problem after posting a form, I can see the form posted and I can bind object. My issue is I have done a database lookup during the process and would like to display the results. How would I do that? all the methods that implement the “action” part of the Controller interface does not return a ModelAndView. Is it some basic Spring fundamental I’m missing?

Neeraj, the Spring Framework Reference Documentation has a lot of information in it. I recommend reading it in some depth. Also, the Spring CVS repository contains a sample portal application that showcases many portlet MVC features.

Hello Author,
I am also exploring Spring Portlet MVC framework and your article give me a good start. Really a good job.
I would love to learn this Framework and also if you can uplaod some sample
HelloWorld portlet based on Spring Portlet MVC Framework, that would be great.

Thanks again.
