I'm new to Torque and trying to get it working as my
persistence engine with a struts application. I can get
torque to generate all my classes and the database schema
and even compile my entire project. However, the second I
try to run a struts action that has a Torque lookup,
everything explodes. I have set up an InitServlet per some
of the other messages on this list, but the servlet keeps
failing to start. I'm not sure if Torque pukes because the
servlet won't init, or if the servlet won't init because
Torque pukes. An interesting catch-22. Anybody with some
experience want to offer any thoughts? Code below.
Thanks in Advance,
Bob
Here's my InitServlet (Again, as posted here before):
package com.mypackage;
import org.apache.torque.Torque;
import javax.servlet.*;
import javax.servlet.http.*;
/**
* Title:
* Description:
* Copyright: Copyright (c) 2002
* Company:
* @author
* @version 1.0
*/
public class InitServlet extends HttpServlet {
// Properties
private int debug = 0;
public void init() throws ServletException {
String value;
value = getServletConfig().getInitParameter("debug");
try {
debug = Integer.parseInt(value);
}
catch (Throwable t) {
debug = 0;
}
log("Initializing Torque ...");
try {
String propFileName =
getServletConfig().getInitParameter("config");
if( propFileName==null ) {
propFileName="WEB-INF/Torque.properties";
}
String propFile =
getServletContext().getRealPath(propFileName);
System.out.println("\n\n\n\n\n Starting Torque
Initialization... \n\n\n\n\n");
log("Torque properties file: " + propFile);
Torque.init(propFile);
System.out.println("\n\n\n\n\n Torque Initialized
\n\n\n\n\n");
}
catch(Exception e){
System.out.println("\n\n\n\n\n Torque Servlet Yacked
\n\n\n\n\n");
throw new ServletException(e.getMessage());
}
}
}
And here's the relevant code of my struts action:
try {
Criteria crit = new Criteria();
QueryList list = new QueryList();
list.setResults(CapitalPaymentPeer.doSelect(crit));
request.setAttribute("PAYMENTS", list);
}
catch (TorqueException e) {
throw new ServletException(e.getMessage());
}
And here's the error I get in the torque log file that it
writes:
