Extracting a value from the j_security_check servlet into a JSP page

[Varnam Aayiram]

Hi Folks...

I have a problem as follows:

I log in into the web app, via my login.jsp page. Below is the code for the form that accepts the login information

<form method="POST" action="j_security_check">
<table cellpadding="0" cellspacing="0" border="0">
  <tr>
    <td align="right">Username: </td>
    <td><input type="text" name="j_username"></td>
  </tr>
  <tr>
    <td align="right">Password: </td>
    <td><input type="password" name="j_password"></td>
  </tr>
  <tr>
    <td></td>
    <td><input type="submit" value="Login"></td>
  </tr>
</table>
</form>

Login is sucessful and I am brought to the 'studentstub.jsp' page. I would like the user name to appear on the 'studentstub.jsp' page. I used the following code in the 'studentstub.jsp' page :

<td><%= request.getParameter("j_username")%></td>

but all I am getting is a null. The 'j_security_check' servlet is not exactly part of my package, but the glassfish app server. Is there anything wrong in the way I am extracting the information from 'j_security_check' ? Hope someone can advise, thanks.

The getRemoteUser() method in HttpServletRequest returns the username of the authenticated user.

Hi Devaka Cooray..

Thanks for the reply, I appreciate it. I tried doing what you mentioned and it worked. I replaced this:

<td><%= request.getParameter("j_username")%></td>  

with this:

<td><%= request.getRemoteUser()%></td>

Thanks alot...
