I used the following code in JSP, to try and retrieve login id and password. For some reason, no value is being shown when I try to output the username value from the bean…What am I missing here?
Code for loginbean.jsp–
<%@ page language="Java" import="java.sql.*" %>
<HTML>
<HEAD><TITLE>DataBase Search</TITLE></HEAD>
<BODY>
<jsp:useBean id="db" scope="session" class="logbean.LoginBean">
<jsp:setProperty name="db" property="*" />
</jsp:useBean>
<jsp:forward page="welcome.jsp">
<jsp:param name="userName" value="<%=db.getUsername()%>" />
<jsp:param name="password" value="<%=db.getPassword()%>" />
</jsp:forward>
</body>
</html>
Code for LoginBean.java–
package logbean;
public class LoginBean {
String userName="";
String password="";
public String getUsername() {
return userName;
}
public void setUsername(String username) {
this.userName = username;
}
public String getPassword() {
return password;
}
public void setPassword(String password) {
this.password = password;
}
}
Code for login.jsp–
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">

Finally, below is code for welcome.jsp–
<HTML>
<HEAD><TITLE>Welcome</TITLE></HEAD>
<BODY>
<br><br><br><br>
<table align="center" style="border:1px solid #000000;">
<jsp:useBean id="db" class="logbean.LoginBean" scope="session"/>
<h4> Just checking to see if text is being shown</h4>
<h1>Welcome <b><%= db.getUsername()%></b></h1>
</table>
</body>
</html>
Looks like you might be missing the jsp:setProperty tag in your welcome JSP (as that’s the one you’re posting to).
