help with jetspeed

[Gil Vernik <Gi...@dbnet.co.il>]

I am new to jetspeed. I have tomcat 5 and jetspeed 1.4b.
I wrote a class : 
public class recieveTraficLight  extends VelocityPortlet
{
 
protected void buildNormalContext(VelocityPortlet portlet,Context context,
                                       RunData rundata)
{
try{
            Service service = new Service();
            Call call = (Call) service.createCall();
 
            call.setOperationName(new QName("AddFunction", "addInt"));
            call.setTargetEndpointAddress(new java.net.URL(
                    "http://localhost:8080/axis/services/AddFunction.jws"));
            call.addParameter("a", XMLType.XSD_INT, ParameterMode.IN);
            call.addParameter("b", XMLType.XSD_INT, ParameterMode.IN);
            call.setReturnType(XMLType.XSD_INT);
           Integer ret = (Integer) call.invoke(new Object[] { new Integer(1),new Integer(2) });
 
           context.put("color_number",ret);
}
catch (Exception e)
{
  e.printStackTrace();
}
}
}
 
I wrote a vm file that checks the $ret variable and print something on the screen. This a vm file : 
#if ($color_name==1) 
   <p>
    <img border="0" src="…>
   </p>
 #end
 
my question is, how to run all this? Where should I put my class file, where should I put vm file, what html will run it?
I got lost with all this, please help me with using it.
