Java/J2EE Developers

[freekill]

Question lang sa mga experienced java devs, I'm currently working for a consulting company. 2 years na exp ko with Struts, Spring, Hibernate and I've also used iBatis in one of my projects before. I also know RIA javascript architectures - Flex, ExtJS and Dojo.

Ano na ba market value ng skillset na to ngayon? Please pm kung bawal ipost. Thanks!

hello java peeps, I'm searching on how to implement multiple submit buttons. Currently I'm doing it using a javascript function, and set a request parameter. And on my controller I just compare the parameters and call a specific function.

Here's my code for javascript

function submitform(){
document.forms[myform].action  = "save.jsp?param=save";
document.forms[myform].submit();
}

here's my controller

@RequestMapping(value="save" , method = RequestMethod.POST)
public ModelAndView saveForm(HttpRequest request){

if (request.getAttribute("param").equals("save")){
 // call save function
save();

}
if (request.getAttribute("param").equals("delete")){
 // call delete function
delete();
}

return new ModelAndView();
}

So far, I am able to do what I want with that approach.
So my question is , is this a good way of implementing multiple submit buttons? if not , what better suggestion can you advice?

Thanks in advance!

Search or Goto:
13.11.3. Mapping requests with @RequestMapping

Note: for every action has corresponding 1 method for example you have a form that has save, update, delete you must create each a method then annotate them with correct RequestMapping.

BTW ModelAndView is oldschool. Base on generate of SpringRoo and Latest sample of Spring MVC they don't use now a ModelAndView.

Hope this will help you.

Happy coding.

Thanks for the reply

Ok, I can see that I need the use of multiactioncontroller to implement multiple submit buttons, however, I cant seem to understand some points of it.

I am using annotation based controller, so lets say i have add, delete , and update buttons in one form, each are submit buttzons.

So I would do this :

@RequestMapping("/customer/add.htm")
	public ModelAndView add(HttpServletRequest request,
		HttpServletResponse response) throws Exception {
 
		return new ModelAndView("CustomerAddView");
 
	}
 
	@RequestMapping("/customer/delete.htm")
	public ModelAndView delete(HttpServletRequest request,
		HttpServletResponse response) throws Exception {
 
		return new ModelAndView("CustomerDeleteView");
 
	}
 
	@RequestMapping("/customer/update.htm")
	public ModelAndView update(HttpServletRequest request,
		HttpServletResponse response) throws Exception {
 
		return new ModelAndView("CustomerUpdateView");
 
	}

So, what I don't get here is each method has a request mapping of different htmls. But on my case, all those buttons are included in only one form in one html ofcourse.

Where am I going wrong here?

Thank you in Advance!

why not create an id? for each type of action. like id=1 is add... etc.

@redcode7000

Ok naman yung unang solution mo, ano ba yung problema sa ganyan? Parang sa struts lang hehe. Or if ayaw mo ng param sa url, pwede mong lagyan ng value yung hidden input box via javascript tapos getAttribute mo nalang.

Kung programmer position ka pa din sa current work mo parang more or less 40-50k yata yan. Basta sa mga Foreign company ha lalo na UK, US, Australian, Canadian companies.

Ganun ba? as I said, nagagawa ko naman yung gusto ko with that kind of approach, kaya lang, I'm thinking of proper or right way of implementing multiple submit buttons in spring.

[tripkoyan]

Ewan ko kung tama to, pero pwede mo rin gawing "get" yung retrieval and "post" yung update and deletions mo.

[redcode7000]

Ewan ko kung tama to, pero pwede mo rin gawing "get" yung retrieval and "post" yung update and deletions mo.

Actually, lahat ng submit buttons ko ay naka post method, even yung retrieval. I wonder pano ko po gagamitin yung get method in retrieval? kasi normally yung get method is used when the page load diba?

I wonder pano ko po gagamitin yung get method in retrieval?

Yung GET method is usually used for, well, GETting resources. Almost same lang sya sa POST in that sense pero if the transaction is "idempotent", then GET is the way to go. Use POST in sending requests to POST data (e.g. logins, submitting filled out forms and the likes). There are also differences in the amount of data you can send between GET and POST.

Also,

document.forms[myform].action = "save.jsp?param=save";

doesn't look that sexy. See if you can use hidden form element or create one on the fly as alternatives for sending the value of "param" parameter.

For retrieval, recommended na GET yung gamit mo. Kasi standard yun sa RESTful design. Hehe. Yung parameters din pag nag GET method ka nakalagay sa URL. Parang site1?username=test tapos sa POST naman nakalagay sa request body.

[redcode7000]

Thanks po sa mga reply nyo. :-)

how about po pala using ajax for retrieval? mas efficient ba yun? I've no experience using ajax eh. Parang nabasa ko lang na it can connect to server without reloading the page so pwede sya sa retrieval operations.

Any Idea? Thanks!

[tripkoyan]

Kung iba iba yung niloload mo sa page, mas OK nga ajax. (example if using tabs) Pero kung one page lang yan, wag ka na mag ajax. Saka try to use javascript libraries kasi usually, tested na yun cross browser and additional skills din yun.

Tama din si lhorenz, gawin mo nalang hidden yung parameter na "param" or create a hidden text box on the fly before submit.

Use Ajax if requirement na dapat highly interactive yung site. Parang facebook lang. Tuwing may nag post, nagpapakita sa feed mo kahit hindi na i-reload yung page.

Actually, misnomer yung Ajax eh. Yung madalas na payload kasi na ginagamit ay JSON hindi XML. Dapat asynchronous javascript and json or AJAJ. Haha

[redcode7000]

I see, Thanks po.

So far, hindi naman highly interactive yung ginagawa ko eh. More on parang data transaction lang. Hehe...

Thanks for being helpful guys!

hi java peeps,

I've been having a problem regarding, I have a form which has a lot of fields , and each fields retrieves a data depending on the associated button that was clicked.

So, each my button, needs to call an ajax request, then the response will be displayed on the associated field.

I wonder if it is possible to call different method in my spring controller once i clicked on different button?

In other words, I want to make a multiple ajax request, and each request will call different method.

for example this code :

// when get account detail is clicked it will call this method
@RequestMapping(method=RequestMethod.POST)
    public @ResponseBody String getAccountDetails(@RequestParam(value="accountid") String accountid){
    	
     return somefunct.getAccountDetails(accountid);

    }



// when get account summary is clicked it will call this method
@RequestMapping(method=RequestMethod.POST)
    public @ResponseBody String getAccountSummary(@RequestParam(value="accountid") String accountid){
    	
      return somefunct.getAccountSummary(accountid);

    }



/* when submit button is clicked... Form is submitted for saving*/
@RequestMapping(method=RequestMethod.POST)
    public String submitForm(){
    	// save here
    	return "myform";
    };*/

Currently what I can do, is to have one ajax request only.


Please , if anyone could help me on this.I really need this functionality and would greatly appreciate your feedback.



Thanks In Advance!!!

[redcode7000]

ok guys, I was able to solve it now!..

I just need to provide a value in my request mapping

// when get account detail is clicked it will call this method
@RequestMapping(value  = "/detail",method=RequestMethod.POST)
    public @ResponseBody String getAccountDetails(@RequestParam(value="accountid") String accountid){
    	
     return somefunct.getAccountDetails(accountid);

    }


// when get account summary is clicked it will call this method
@RequestMapping(value  = "/summary", method=RequestMethod.POST)
    public @ResponseBody String getAccountSummary(@RequestParam(value="accountid") String accountid){
    	
      return somefunct.getAccountSummary(accountid);

    }


/* when submit button is clicked... Form is submitted for saving*/
@RequestMapping(method=RequestMethod.POST)
    public String submitForm(){
    	// save here
    	return "myform";
    };

then, the ajax code for each button is

// button detail is clicked

$("#btndetail").click(function() {
										var accountid= $("#accountid").val();
										$.ajax({
type : "POST",
url : "/mypage/detail",
data : "accountid=" + accountid,
success : function(response) {// we have the response
alert(response);	},
error : function(e) {
alert('Error: ' + e);
}
});

										});



// button summary is clicked

$("#btnsummary").click(function() {
										var accountid= $("#accountid").val();
										$.ajax({
type : "POST",
url : "/mypage/summary",
data : "accountid=" + accountid,
success : function(response) {// we have the response
alert(response);	},
error : function(e) {
alert('Error: ' + e);
}
});

										});
