Michael,
1. Your input form should not contain iterator - it is for input. You need
to define your <html:text> tags inside an <html:form action="/saveGBEntry"
method="post"> and declare this bean and action in struts-config.xml like
<form-bean name="GBEntryForm"
<!--name of the bean-->
type="com.morelogs.guestbook.GBEntryForm" />
<action-mappings>
<action path="/saveGBEntry"
type="com.morelogs.guestbook.action.SaveGBEntryAction"
name="GBEntryForm"
input="/welcome.jsp"
scope="session"
validate="true" >
<forward name="success" path="/displayGBEntries.jsp" />
</action-mappings>
2. When you submit welcome.jsp, it fires SaveGBAction and automatically
sets the propertiies of GBentryForm (mainly in case the user needs to return
because of an error). You can now access all the bean properties:
GBEntryForm entryForm = (GBEntryForm) form;
which you can use to save the data to the database. After which, make your
call to your session EJB and set the gbEntry property in the form bean:
entryForm.setGbEntry( entryList);
When done, struts will forward the request to displayGBEntries.jsp, where
you then iterate throught the list:
<logic:iterate name="GBEntryForm"
id="gbEntry"
scope="session"
property="gbEntry"
type="com.morelogs.guestbook.interfaces.gbEntry">
<bean:write name="gbEntry" property="entry_subject" />
<bean:write name="gbEntry" property="entry_name" />
<bean:write name="gbEntry" property="entry_date" />
</logic:iterate>

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
