JSP tags problem

Jack · #1 (**permalink**) 06-13-2007, 02:59 PM

I have the following problem: when I try to create a list that is inside of the vertical scroll the information of the list doesn't appear.
Do I mix the tags? I want the list from a collection of objects
Can you help me?

my page.jsp:

Code:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<%@page contentType="text/html"%>
<%@page pageEncoding="UTF-8"%>
<%@taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c"%> 
<%@taglib uri="/WEB-INF/struts-html-el.tld" prefix="html" %>
<%@taglib uri="/WEB-INF/struts-bean-el.tld" prefix="bean" %>
<%@page import="XXX.beans.UserBean" %>

<html:html xhtml="true">
<head>
<title>XXX</title>
</head>

<body> 
<form name="form1" method="post" action="${LISTAR_ACTION}">

<html:select property="users" title="Users" size="4" multiple="false">
<html:option value="all">ALL</html:option>

<html:optionsCollection name="usersList" label="userId" value="userId" />
</html:select>

<input type="submit" name="List" value=" List" />
</form>

</body>
</html:html>

my code:

Code:


Collection usersList= new Vector();
if (resultUsers != null ){
while(resultUsers.next()){
UserBean usrBO = new UserBean();
usrBO.setName(resultUsers.getString("userId"));
usrBO.setAuthModules(null);
usrBO.setPasword(null);
usersList.add(usrBO);
} 
}

The problem is that you don't send the collection to the JSP.
Example:

request.setAttribute("usersList", userList);

I don't think that it is the problem.
the problem is that your collection is null
check it and then tell us
