jsp:setProperty

[niranjan mohan]

Hi

I tried using the jsp set property to get the form elements , by setting the request to session object and getting the values in the servlet . It does not work when i don't give the value

in the JSP

<jsp:useBean id ="userbean" class="BVO.UserVO" >
   <tr>
       <td>
         User Name
        </td>
        <td><input type="text"  name="user" />
        </td>
    </tr>
    <tr>
           <td>password</td>
           <td><input type="password" name="pass" /></td>
     </tr>
     <tr>
     
              <td><input type="submit" value="login" /></td>
             <td><input type="reset" value="cancel" /></td>
    
    </tr>
      
       		<jsp:setProperty name="userbean" property="user" param="user"/>
       	</jsp:useBean>
       	<% session.setAttribute("loginb", request.getAttribute("userbean")); %>

In the servelt the Object is null , but instead of mentioning the param if i explicitly state the value="XXX" i get the correct bean in the servlet .



The below code works

   <tr>
       <td>
         User Name
        </td>
        <td><input type="text"  name="user" />
        </td>
    </tr>
    <tr>
           <td>password</td>
           <td><input type="password" name="pass" /></td>
     </tr>
     <tr>
     
              <td><input type="submit" value="login" /></td>
             <td><input type="reset" value="cancel" /></td>
      </tr>
      <jsp:useBean id ="userbean" class="BVO.UserVO" >
       		<jsp:setProperty name="userbean" property="user" value="admin"/>
       	</jsp:useBean>
       	<% session.setAttribute("loginb", request.getAttribute("userbean")); %>

Hi. Well, I´m kind noob in JSP and Servlets myself, but this code looks a little strange. See, you´re trying to get and set the user property in the same page. So, on this situation, the "param" attribute should work? In runtime the code with the "param" attribute will run but you don´t have the "param" at this moment since the user haven´t typed yet, you see..

I was trying to test the

 <jsp:setProperty name="instanceName" property="*"/>

functionality , it did not work .
