Trouble with passing ModelAndView Object to JSP Page

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.

Still not working...

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.
