Jsp bean error

Jsp bean error

2004-01-07       - By X V Jay

Hi,
I have been unable to use jsp beans.

Here are the code fragments....

ControllerServlet.java
public class ControllerServlet extends HttpServlet
{
public void init(ServletConfig config) throws ServletException
{
.....
.....
   // instantiate the DbBean
   DatabaseBean databaseBean = new DatabaseBean();
   // intialise the bean's fields
   databaseBean.setDbUrl(config.getInitParameter("dbUrl"));
   databaseBean.setDbUserName(config.getInitParameter("dbUserName"));
   databaseBean.setDbPassword(config.getInitParameter("dbPassword"));

   // put the bean in the servlet context
   context.setAttribute("theBean",databaseBean);
}
......
......
}

I am now trying to use the databaseBean in process.jsp

<%@ page import="java.util.*" %>
<%@ page import="javax.servlet.*"%>
<%@ page import="javax.servlet.http.*"%>
<jsp:useBean id="theBean" scope="application" class="DatabaseBean" />
<jsp:setProperty name="theBean" property="username"/>
<jsp:setProperty name="theBean" property="password"/>
.......
.......

This is error reported by Tomcat.
