I have had a couple of problems in dispatching data from a servlet to a JSP
using JRUN3.0.
The data I am dispatching from a servlet, PKIMonitorServlet, to a JSP page,
PKIMonitor.jsp, is a JavaBean, PKIStatus, with data as shown below:
public class PKIStatus implements java.io.Serializable
{
// data
private String date;
private String time;
private String administrator;
private String aceStatus;
private String kssStatus;
private String armStatus;
etc.
The error message that I get is ( The error page, ErrorPage.jsp, is
attempted because /PKIWebAdmin/jsp/PKIMonitor.jsp cannot be found ):
404 Not Found
/servlet/com.rsa.ps.PKIWebAdmin.PKIMonitorServlet:
allaire.jrun.JRunServletException: The page /PKIWebAdmin/jsp/ErrorPage.jsp
could not be found.

If I change the data in the bean as follows, the JSP is displayed correctly:
public class PKIStatus implements java.io.Serializable
{
// data
private String date;
private String time;
private String administrator;
private int aceStatus;
private int kssStatus;
private int armStatus;
etc.
The JSP is as follows:
<HTML>
<HEAD>
<TITLE>
PKI Monitor Servlet
</TITLE>
</HEAD>
<BODY>
<%@ page language="java" import="com.rsa.ps.PKIAdmin.beans.*" %>
<TABLE BORDER="1">
<TR>
<TH>Date</TH>
<TH>Time</TH>
<TH>Administrator</TH>
<TH>ACE Status</TH>
<TH>KSS Status</TH>
<TH>ARM Status</TH>
</TR>
<%
PKIStatus pkiStatus[] = (PKIStatus
[])request.getAttribute("StatusArray");
int noItems = pkiStatus.length;
for( int i = 0; i < noItems; i++ )
{
%>
<TR>
<TD><%= pkiStatus[i].getDate() %></TD>
<TD><%= pkiStatus[i].getTime() %></TD>
<TD><%= pkiStatus[i].getAdministrator() %></TD>
<TD><%= pkiStatus[i].getAceStatus() %></TD>
<TD><%= pkiStatus[i].getKssStatus() %></TD>
<TD><%= pkiStatus[i].getArmStatus() %></TD>
</TR>
<%
}
%>
</TABLE>
</BODY>
<HTML>
The second problem that I have relates to the JSP itself. If I use
'useBean' and display the properties using <jsp: getProperty> instead of the
pure java code that I use above then all Strings appear as 'null' and all
integers appear as 0 irrespective of their true value. ( Case where I use 3
strings and 3 integers in PKIStatus). This problem appears on both JRUN2.3
and 3.0. I have checked the code out on Java WebServer and the data is
displayed correctly.
