DisplayTag Library Question
Hi All,
For some reason I'm having trouble with displaying my list data with
the DisplayTag Library . . . I'm new to Struts (and the
DisplayTagLibrary) so hopefully it's something simple . . .
In my implementation class I have a method that uses Hibernate to get
some data from an Oracle Database. The List (in this case called
"results") is returned to the caller . . . which is a Struts Action.
The first part of this file is shown below as well . . .
public List getDefects( ) throws DatastoreException
{
List results = null;
List items = null;
Session session = null;
try
{
session = sessionFactory.openSession( );
Query q = session.createQuery("select DefectID, Description,
PriorityID from Defect");
results = q.list( );
session.close( );
}catch( Exception ex ){
ex.printStackTrace( );
throw DatastoreException.datastoreError(ex);
}
return results;
}
public class TestAction extends Action
{
public TestAction()
{
super();
}
public ActionForward execute (ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws
Exception
{
ActionErrors errors = new ActionErrors();
ActionForward forward = new ActionForward();
// return value
//SubmitForm submitForm = (SubmitForm) form;
try
{
System.out.println("Go Away");
EricEnhancementServiceImpl E = new EricEnhancementServiceImpl();
List results = E.getDefects();
for (ListIterator iter = results.listIterator(); iter.hasNext
() ; )
{
Object[] row = (Object[])iter.next();
Integer id = (Integer)row[0];
String desc = (String)row[1];
Integer priorityid = (Integer)row[2];
}
request.setAttribute("stuff", results);
As you can see in the action the "results" list is stored in
session . . .
The .jsp where I'm just trying to display the results of the data that
is in my list is shown below:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><%@page
language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@taglib uri="http://struts.apache.org/tags-html" prefix="html"%>
<%@taglib uri="http://struts.apache.org/tags-bean" prefix="bean"%>
<%@ taglib uri="http://displaytag.sf.net" prefix="display" %>
<%@ taglib uri="http://displaytag.sf.net/el" prefix="displayel" %>
<html:html>
<head>
<title>defect</title>
<meta http-equiv="Content-Type" content="text/html;
charset=ISO-8859-1">
</head>
<body>
<jsp:include page="strutsmenu.jsp"/>
<display:table name="stuff"/>
</body>
</html:html>
When I try to execute the Struts application I get the memory location
printed instead of the data (like this). As far as I know all .jar
file and .tld files are present.

Can someone please tell me what I'm doing wrong . . .
Thanks,
Pete
