Shiro login requirement

[Dinakar Reddy <dr...@inonde.io.INVALID>]

Hi,

We are currently using shiro framework for authentication. The requirement is, for invalid login the login.jsp should have the invalid username prepopulated in the page. Here is my sample code of the jsp. Username value is the desired failed login username, but the pageContext.setAttribute is not setting the username in the form field. Can you please help or provide direction in this?

<%

if (request.getAttribute("shiroLoginFailure")!=null) {

pageContext.setAttribute("loginError", request.getAttribute("shiroLoginFailure"));

System.out.println("username : "+request.getParameterMap().get("username")[0]);



pageContext.setAttribute("username", request.getParameterMap().get("username")[0]);

}

%>






                                                <c:if test="${not empty loginError}">
                                                       <div class="text-center error">
                                                       You have entered an invalid username or password. Please try again.
                                                       </div>
                                                </c:if>
                            login                     <div class="form-group form-group-material">
                                                       <label class="control-label text-semibold text-size-small animate">USERNAME</label>
                                                       <input type="text" name="username" class="form-control inonde-login-landing" placeholder="username">

                                                       <label class="control-label text-semibold text-size-small animate">PASSWORD</label>
                                                       <input type="password" name="password" class="form-control inonde-login-landing" placeholder="password">
                                                </div>
                                                <input type="hidden" name="local_timezone" id="local_timezone" value="" />
                                                <div class="form-group">

Hi DInakar,

If you see something printed using System.out.println(), you are
probably already setting the attribute correctly.
It has been some time since I touched JSPs, though.

Inside your input, you need to specify the value:

<input
   name="username"
   <c:if test="${not empty username}">${username}</c:if>
  />

Please see if it works for you.
