Create a listener in your bussinnes process BPEL

When you´re execute a BPEL. I dont how debug a error. To see inside of a execution engenner you could implement a listener  


import java.util.Properties;
import org.apache.ode.bpel.evt.BpelEvent;
import org.apache.ode.bpel.evt.EventContext;
import org.apache.ode.bpel.iapi.*;

public class Listener implements  BpelEventListener {
   
    EventContext context;
   
    @Override
    public void onEvent(BpelEvent arg0) {
        context =arg0.eventContext;
        // TODO Auto-generated method stub
        String evento ="";
        evento = evento+ "--------------------------------\n";
        evento = evento+ "evento: ["+arg0.eventName(arg0)+"] \n";       
        evento = evento+ "linea : ["+arg0.getLineNo()+"] \n";
        evento = evento+ "tipo  : ["+arg0.getType()+"] \n";
        evento = evento+ getNamesVariables();
        evento = evento+ "--------------------------------\n";
        System.out.println(evento );

    }

    @Override
    public void shutdown() {
        // TODO Auto-generated method stub
        ;
        System.out.println( "-------------shutdown---------------\n");
       
    }

    @Override
    public void startup(Properties arg0) {
        String evento ="";
        // TODO Auto-generated method stub
        evento = evento+ "--------------------------------\n";
        evento = evento+ arg0 ;
        evento = evento+ "--------------------------------\n";
        System.out.println(evento );

    }
    private String getNamesVariables(){
        String cadena="";
        for(String variable :context.getVariableNames()){
            cadena = cadena +" variable["+ variable+"]\n";
        }
        return cadena ;
    }

}


build a class and copy  inside folder
apache-tomcat-5.5.33\webapps\ode\WEB-INF\classes

if  you dont create a file in  ode-axis2.properties you to have to create in
apache-tomcat-5.5.33\webapps\ode\WEB-INF\conf
