jsp:setproperty not working
having troubling getting the jsp:setProperty to work. here is my jsp page and bean...can anyone tell me why this is not working? If i explicitly set the value="something" then setProperty works, but I need to capture the html input...thanks in advance!
here's my jsp page called login.jsp:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%
<%@ page session="true" %>
<jsp:useBean id="user" scope="session" class="org.stuff.domain.Us
<jsp:setProperty name="user" property="*"/>
</jsp:useBean>

<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>Insert title here</title>
</head>
<body>
username: <%= user.getUsername() %>
<br/>
<form action="login.jsp" method="post">
Login id:
<input type="text" name="username" size="10"/>
<br/>
Passwd:
<input type="password" name="password" size="10"/>
<br/>
<input type="submit" name="submit"/>
</form>
</body>
</html>
And here is my bean:
package org.stuff.domain;
public class User implements java.io.Serializable {
private String username;
private String password;
public User() {
// TODO Auto-generated constructor stub
}
public String getPassword() {
return password;
}
public void setPassword( String password ) {
this.password = password;
}
public String getUsername() {
return username;
}
public void setUsername( String username ) {
this.username = username;
}
here's my jsp page called login.jsp:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%
<%@ page session="true" %>
<jsp:useBean id="user" scope="session" class="org.stuff.domain.Us

This solution is only available to members.

Body tags are only processed if <jsp:useBean> instantiates the Bean. If the Bean already exists and <jsp:useBean> locates it, the body tags have no effect.
Using
<jsp:useBean id="user" scope="session" class="org.stuff.domain.Us
<jsp:setProperty name="user" property="*"/>
will set the property even if the bean already exists
Using
<jsp:useBean id="user" scope="session" class="org.stuff.domain.Us
<jsp:setProperty name="user" property="*"/>
will set the property even if the bean already exists
remove scope="session" and it will work
