Create JavaBean in Servlet??

[loewen]

I would like to create a servlet that:
1. does some processing
2. stores the results in a JavaBean
3. forwards to a .jsp

The .jsp page will read the results from the bean and display the formatted results.

How do you instantiate a JavaBean from within a servlet that will be accessible to the jsp? I know how to use the <jsp:useBean> tag to create a bean to share info between .jsp pages.

Here's what I have so far:

(servlet)
..do processing..
MyBean bean = new MyBean();
bean.setTitle = &quot;Title of Document&quot;;
bean.setId = &quot;ID of document&quot;;
RequestDispatcher dispatcher = getServletContext().
getRequestDispatcher(&quot;app/display.jsp&quot;
dispatcher.forward(request,response);

(jsp)
...
<jsp:useBean id=&quot;bean&quot;
class=&quot;myapp.MyServlet&quot;
scope=&quot;session&quot;>
title:<br>
<jsp:getProperty name=&quot;bean&quot; property=&quot;title&quot;><br>
id:<br>
<jsp:getProperty name=&quot;bean&quot; property=&quot;id&quot;><br>


The display.jsp page displays blanks for all properties. So it must be instantiating a new bean, instead of accessing the one I tried to create in my servlet.

Obviously i'm missing something pretty basic here. Can anyone help?

Having the same problem with a book example (Manning's Web Development with Java Server Pages, pp. 256-261.).
This example:
1.
uses a servlet to access a database (successfully gets 101 records) and loads them into a vector called 'list' containing beans of class EmployeeBean and does a setAttribute(&quot;list&quot;,list) to provide the vector to the JSP.
2. forward to JSP page
3. jsp page does a <jsp:useBean id=&quot;employee&quot; class=...>
4. jsp does a loop on the vector as follows:
<%
Vector v = (Vector)request.getAttribute(&quot;list&quot;
Iterator i = v.iterator();
while (i.hasNext()) {
employee = (EmployeeBean)i.next();
%>
<jsp:request.getProperty name=&quot;employee&quot; property=&quot;id&quot;/>,
<jsp:request.getProperty name=&quot;lastName&quot; property=&quot;loginId&quot;/>
<%
}
%>

The output is 101 initialized records(id = 0, lastName=&quot;&quot.
Sounds like scope is the issue, but changing scope of the useBean does nothing.

Let me know if you can figure this out.
