Hi all,
I try to get Torque running with Tomcat and followed all the hints in this
mailing lists.
I decided to init Torque with an InitServlet:
package com.bookshop;
import org.apache.torque.Torque;
import javax.servlet.*;
import javax.servlet.http.*;
public class InitServlet extends HttpServlet
{
/**
* The debugging detail level for this servlet.
*/
private int debug = 0;
public void init() throws ServletException
{
// super.init(config);
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);
log("Torque properties file: " + propFile);
Torque.init(propFile);
}
catch(Exception e){
throw new ServletException(e.getMessage());
}
}
}
I try to load this servlet with the following entry in web.xml:
<!-- Torque Initialization Servlet -->
<servlet>
<servlet-name>initServlet</servlet-name>
<servlet-class>com.bookstore.InitServlet</servlet-class>
<init-param>
<param-name>config</param-name>
<param-value>/WEB-INF/Torque.properties</param-value>
</init-param>
<init-param>
<param-name>debug</param-name>
<param-value>2</param-value>
</init-param>
<load-on-startup>1</load-on-startup>
</servlet>
This does not work as my logfiles tell me:
2002-08-15 10:27:24 StandardWrapper[/bookshop:initServlet]: Marking servlet
initServlet as unavailable
2002-08-15 10:27:24 StandardContext[/bookshop]: Servlet /bookshop threw

I suggested that this might be a classpath error. But the InitServlet is
stored in my classes directory (where all the other classes are stored in
and which work!)
Thanks for your help-
Christian
