Here's an example from a .jsp file:
<%@ page import = "some.package.name.VpnHostsBean" %>
<jsp:useBean id="vpnHosts"
class="some.package.name.VpnHostsBean" scope="session" />
<HTML>
<HEAD>
...
<TABLE BORDER=0 bgcolor="#336699" CELLPADDING=5 CELLSPACING=2 WIDTH=100%>
<% for (int i = 0; i < vpnHosts.getNumHosts(); i++ ) { %>
<tr><td bgcolor='#6699CC' width=150 align=right><font face='arial,
san-serif' color='#FFFFFF'>
<%= vpnxHosts.getName(i) %>
</font></td>
<td bgcolor='#DDDDDD' width=350 align=left><font face='arial, san-serif'
color='#000000'>
<%= vpnHosts.getAddress(i) %>
</font></td></tr>
<% } %>
</TABLE>
...
Here's part of the associated bean:
package some.package.name;
import java.util.*;
import java.io.*;
public class VpnHostsBean extends java.lang.Object implements Runnable
{
...
protected int numHosts = 0;
public int getNumHosts() {
numHosts = addresses.size();
return numHosts;
}
protected Vector names = new Vector();
public String getName(int i) {
return (String)names.elementAt(i);
}
protected void setName(int i, String value) {
if (i >= names.size())
names.setSize(i + 1);
names.setElementAt(value, i);
}
protected Vector addresses = new Vector();
public String getAddress(int i) {
return (String)addresses.elementAt(i);
}
protected void setAddress(int i, String value) {
if (i >= addresses.size())
addresses.setSize(i + 1);
addresses.setElementAt(value, i);
}
...
}
Hope that helps,
Larry

Subject: Indexed properties / iterating through arrays
Hi!
The JSP 1.0 spec mentions those in exactly two places.
What are indexed properties and how can I work with them?
Alternatively, what's the best way to return an array
from a getProperty() method into the JSP page and interate
through it?
Thanks, Joel
