I use the commons-configuration-1.0-dev-3.jar which has a new method in
org.apache.commons.configuration.ConfigurationFactory called
setConfigurationURL().  This is used to get a Configuration object which you
then use in Torque.init(configuration) in place of Torque.init(pathName).
My code then looks like this:

        ConfigurationFactory factory = new ConfigurationFactory();
        URL configURL =
this.getClass().getResource("/Torque.properties.xml"); // an xml file in my
web-inf directory
        factory.setConfigurationURL(configURL);
        
        try {
            Configuration configuration = factory.getConfiguration();
            Torque.init(configuration);
    	} catch (Exception ex) {
	}

Then the contents of Torque.properties.xml are:

<?xml version="1.0" encoding="ISO-8859-1" ?>

<configuration>
  <properties fileName="Torque.properties"/>
</configuration>

You may have some versioning issues by getting that newer
commons-configuration jar so you may also need newer versions of other jars,
like beanutils-1.6.1, collections-2.1, lang-2.0, etc.  I have all these
newer jars but don't remember if I needed them specifically because of the
updated configuration jar.

Torque.init() requires an absolute pathname. It's a bummer.

I put the true pathname in another properties file so that I do not have to
hard-code it in the program. This does mean, however, that I have to know
the absolute path where, in my case, Tomcat is installed. Here is my
initialisation code

        apiResources = ResourceBundle.getBundle("betapi");
        if (!Torque.isInit()) {
            String configFile = apiResources.getString
("betapi.torqueconfig");
            try {
                Torque.init(configFile);
            } catch (TorqueException e) {
                  context.log(e,"Cannot initalise Torque: " + e.toString()
);
                e.printStackTrace(System.err);
                System.exit(1);
            }
        }

and betapi.properties contains:
      betapi.torqueconfig=
/users/rxm1676/workspace/pmfeditor/WEB-INF/classes/Torque.properties


In cases where I build on one machine but run on another I have a little
shell script that that runs on installation. It tracks down the appropriate
line in betapi.properties and adjusts it so suit where the code is actually
installed.

the problem is not confusing presentation and model but when i compile in
jdev i have the exception "Could not open file Torque.properties"because i
must put it in a specific directory in jdev that i don't know.

this is the code:

affichage.jsp:


<table width="165" border="0" cellpadding="2" cellspacing="0" class
="textindex">
<%
Iterator i;
List listecr=(List)session.getAttribute("liste");
 i = listecr.iterator();
 while ( i.hasNext() )
 {
  Ecriture monecriture = (Ecriture) i.next();
%>
          <tr>
           <td width="8" align="center">
                      <%= monecriture.getCodeetape()%>
                      </td>

          </tr>
<%
 }
%>
         </table>



actionaccueil.java


      public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response) throws
IOException, ServletException
  {
    HttpSession session=request.getSession();

    AddEcriture test=new AddEcriture();
    test.afficher();

    session.setAttribute("liste",test.getListecrs());
    return mapping.findForward("success");
  }
}

AddEcriture.java:



package si.av;

import java.util.*;
import org.apache.torque.Torque;
import org.apache.torque.util.Criteria;
import si.av.om.*;

public class AddEcriture
{

 List listecrs;
 public List getListecrs()
 {return listecrs;}

  public void afficher()
  {
  try{
      Torque.init("Torque.properties");

     Criteria critaffichage=new Criteria();
      critaffichage.addAscendingOrderByColumn(EcriturePeer.NSEQUENCE);
      listecrs=EcriturePeer.doSelect(critaffichage);

  }

  catch(Exception e){e.printStackTrace();}
  }

}
