I thought it desirable to return the user to the orginating form when fields failed to validate. I'm fairly certain that setting up a multiactioncontroller would give me the functionality, but this might be a bit messy and there might be a better approach. This is great stuff.

You should think about going into publishing a book - half the books out there on java technologies are not up to snuff.

I have two questions (if you could just email me directly): (1) Where can I get a reciepe on setting up SPRING binding? I have experience with Struts on my previous 2 applications (personal apps), and alittle bit of SPRING DAOs. (2) I need to build an arsenal to convience my boss that it is okay to put some POJOs to session (making sure to remove them when the application is done with them of course). Currently everything is being put to request, so when everytime a form is submitted the application has to go back to the DB and "re-inflate" the object the page represented. This is really bad because if the page has labels the represent properties of the object they are lost when the form is submitted (not added to the param mapping). Any advice would be great THANKS!

What I'd really like is something that allows you to do validation with hardly any code and no xml/mapping files.

That was quite interesting, but how we can bind information in case we were using a MultiActionController???? Thanks! Ok.

I think you put it right command bean is a complete misnomer. If these page controllers were called command beans there was no problem. But these command beans should be called form beans. Struts got it right. What do you think. Cheers... dhrubo Hi Jon,

Bean must have a default constructor. In Spring 2.5 it a little more flexible e.g. @RequestMapping("/myurl.html") public ModelAndView addMultiple(@ModelAttribute("command") SearchCommand command, HttpServletRequest request, HttpServletResponse response) Not sure why you need any of this, if you use a MultiActionController you may specify a command object as a 3rd parameter

e.g.

public ModelAndView handleViewList(HttpServletRequest request,
HttpServletResponse response, SearchCommand searchCommand) throws Exception {

where SearchCommand is the command object - any request parameters that match its properties will be bound automatically. Bean must have a default constructor.

In Spring 2.5 it a little more flexible e.g.

@RequestMapping(”/myurl.html”)
public ModelAndView addMultiple(@ModelAttribute(”command”) SearchCommand command,
HttpServletRequest request, HttpServletResponse response)
