Trouble with passing ModelAndView Object to JSP Page

**sumittyagi** · Apr 24th, 2011, 10:39 PM

Hi,
I am new to spring and trying to pass the ModelAndView object from the controller to the JSP page.
Here is my controller code.

Code:

@RequestMapping("/login")
    public ModelAndView login() {
    	LOGGER.info("Inside LOGIN");
    	Health health = null;
    	health.setPasskey("abcd");
    	return new ModelAndView("/admin/login", "health",health);
    	/
    }

Here is my HTML/JSP code

HTML Code:

<html>
<head>
<title>
Health Page Login
</title>
</head>
 
<body  style="overflow: auto; padding:10px;">
<div class="sectionheader">
	<div class="sectionheader-left"><h1>Health Page Login</h1></div>
</div>
<form id="command" action="mediareport" method="post">
<div class="formlayout">
<fieldset title="Search" >
	<div class="formelements">
		<div class="floatleft" style="clear:both;">
			<label style="width:200px;">Please enter password:</label>
			<input type="Password" name="Password" size="10"></input>
			<INPUT TYPE="HIDDEN" NAME="key" <c:out VALUE="${health.getPasskey}" /> </INPUT>
			<input type="submit" value="Login" name="submit" />
		</div>
	</div>
</fieldset>
</div>
</form>

</body>
</html>

on the mediareport page...when I am trying to get the value of variable ${health.getPasskey} via request.getParameter("key"); it displays ${passkey} instead of "abcd". Please help me regarding this....

Hi,

Try

Code:

<INPUT TYPE="HIDDEN" NAME="key"  VALUE="${health.passkey}" />

instead. Where "passkey" is a property in the health class.

Is there any reason you're not looking into Spring Security? You'll probably save a lot of time and work if you use this instead of implementing your own.

Here is my controller code..

Code:

@RequestMapping("/login")
    public ModelAndView login() {
    	LOGGER.info("Inside LOGIN");
    	
    	Health health = null;
    	health = healthLogic.getHealthPasskey();
    	
    	return new ModelAndView("/admin/login", "health",health);

Here is the code for getHealthPasskey() in HealthLogic Class

Code:

public Health getHealthPasskey(){
    	Health health = new Health();
    	health.setPasskey("abcd");
    	return health;
    	
    }

Here is the HTML

HTML Code:

<html>
<head>
<title>
Health Page Login
</title>
</head>
 
<body  style="overflow: auto; padding:10px;">
<div class="sectionheader">
	<div class="sectionheader-left"><h1>Health Page Login</h1></div>
</div>
<form id="command" action="mediareport" method="post">
<div class="formlayout">
<fieldset title="Search" >
	<div class="formelements">
		<div class="floatleft" style="clear:both;">
			<label style="width:200px;">Please enter password:</label>
			<input type="Password" name="Password" size="10"></input>
			<INPUT TYPE="HIDDEN" NAME="key"  VALUE="${health.passkey}" />
			<input type="submit" value="Login" name="submit" />
		</div>
	</div>
</fieldset>
</div>
</form>

</body>
</html>

When I am trying to get the value of health.passkey by request.getParameter("key"), it is still printing "${health.passkey}" ....
Any idea...

I assume this is an example app, otherwise I agree about using Spring Security.

But for your issue, what is your view resolver config?

As a general tip, I recommend looking at the Pet Clinic code and what Spring Roo generates.
