Hi,
thanks for the response.
I�ve done exactly as you said and I get the following error message:
=========== ERROR ========================

=============================================================
Here�s the call to my session bean:
========== CALL TO SESSION BEAN ==============================
// Get a naming context
InitialContext jndiContext = new InitialContext();
// Get a reference to a EntryBean
Object ref = jndiContext.lookup("ejb/guestbook/gbEntries");
// Get a reference from this to the Bean's Home interface
gbEntriesHome home = (gbEntriesHome)
PortableRemoteObject.narrow (ref, gbEntriesHome.class);
ArrayList entryList = new ArrayList();
gbEntries entriesObj = home.create();
Object[] entries = entriesObj.getEntriesList();
for (int i = 0; i < entries.length; i++)
{
gbEntry entry = (gbEntry) entries[i];
entryList.add(entry);
// I get the results printed in my output screen so this works.
System.out.println (entry.getEntry_subject() + "\t" +
entry.getEntry_text() + "\t" +
entry.getEntry_date() + "\t" + entry.getEntry_views());
}
request.setAttribute("entryList", entryList);
================================================================
Here�s the change in my JSP file:
=============== JSP FILE ========================================
<%@ page language="java" %>
<%@ taglib uri="/WEB-INF/struts-html.tld" prefix="html" %>
<%@ taglib uri="/WEB-INF/struts-form.tld" prefix="form" %>
<%@ taglib uri="/WEB-INF/struts-bean.tld" prefix="bean" %>
<%@ taglib uri="/WEB-INF/nested-tags.tld" prefix="nested" %>
<logic:iterate name="entryList"
id="gbEntry"
scope="request"
type="com.morelogs.guestbook.interfaces.gbEntry">
<tr>
<td><html:text property="entry_subject" /></td>
<td><html:text property="entry_text" /></td>
<td><html:text property="entry_date" /></td>
</tr>
</logic:iterate>
===============================================================
Could you please have a look over this to see if I have missed something.
I would really appreciate further help on this.
Regards,
Michael
