Get json data

[nuwan wickramanayaka]

I am developing change password screen using jquery / struts2 with annotations
Which contains fields oldpassword, new password, confirmpassword

This is my html with jquery

<div id="data_control"> <div id="data_control_title" class="cbxTitle"> <font>Change Password</font> </div> <div id="data_control_content" class="cbxContent"> <!-- Data Entry Fields --> <form id="frmData"> <table border="0" > <tr> <td > <font>Enter Old Password:</font> <awc:mandatoryField /> </td> <td > <input type="password" id="oldPassword" name="oldPassword" dispName="Old Password" class="inputField" maxlength="12" validate="mandatory"/> </td> </tr> <tr> <td > <font>Enter New Password:</font> <awc:mandatoryField /> </td> <td > <input type="password" id="password" name="password" dispName="New Password" class="inputField" maxlength="12" validate="mandatory"/> </td> </tr> <tr> <td > <font>Confirm New Password:</font> <awc:mandatoryField /> </td> <td > <input type="password" id="confirmedPassword" name="confirmedPassword" dispName="Confirm Password" class="inputField" maxlength="12" validate="mandatory"/> </td> </tr> </table> </form> <!-- Message Panel --> <awc:messagePanel /> </div> </div> <!-- BUTTON PANNEL CONTAINER --> <table border="0" > <tr> <td> <button id="btnClose" onclick="closePage();" privilege="" class="clsButtonSmall">Close</button> <button id="_btnClear" onclick="initialize();" privilege="" class="clsButtonSmall">Clear</button> </td> <td > <button id="btnSave" onclick="save();" class="clsButtonSmall">Save</button> </td> </tr> </table>

This is my changepassword java script

	var isAdd = false;					

	function setDefaultFocus(id) {
		// Do not change the timeout. Only modify the ID.
		setTimeout("setFocus('"+id+"')", 300);
	}
	
	function initialize(fnAfterInit) {
		
		loadCheck(function() {
			initializeMessage();
			clearForm("frmData");			
			setDefaultFocus("oldPassword");
			triggerEvent("init");			
			if (fnAfterInit) {
				fnAfterInit();
			}
		});
	}
	
	/**
	 * Save Operation.
	 */
	function save() {
		initializeMessage();
		/****************** data form validation **********************/
		if (!validateForm("frmData")) {
			showMessage("W", getMessage("validation-failed"));
			return false;
		}
		
			var frm = $("#frmData");
		
	       var dat = JSON.stringify(frm.serializeArray());
		   
	       alert(dat);
	       $.getJSON('savePassword',
	         dat,
	         function(data) {	    	   
	        	 initialize();
	        	 triggerEvent("save");
	         }
	       );	       
	}
	function onLoad(){
		
		hideProgress();
		initialize();
	}
	onLoad();

This is my struts 2 action class

@Action(value = "changePassword", results = { @Result(name = Struts2Constants.JSP.CHANGE_PASSWORD_JSP, location = Struts2Constants.JSP.CHANGE_PASSWORD_JSP) })
	public String showSamplePage() {

		return Struts2Constants.JSP.CHANGE_PASSWORD_JSP;
	}

	
	@Action(value = "savePassword", results = { @Result(name = Struts2Constants.Result.SUCCESS, type = "json"), @Result(name = Struts2Constants.Result.ERROR, type = "json") })
	public String save() {
		
		System.out.println("HI####");	
		return SUCCESS;

	}

When i click save button of chnagepassword html the save method of java script is executing and 'dat' varitable popolated with data.

So what i want is, how to get the json object data in java side?

help me

Why are you submitting the form using JSON instead of just submitting the form?
