Hi I'm new to JBoss and even to Java, so please, be patients ;) I was
reading the list archives and I found many similar questions but I could
not find one that helps.
I'm trying to develop a "helloWord" app to JBoss 4.2.2GA+Seam2.0.1CR1,
the code I wrote is this:
import javax.ejb.Local;
--------------The interface----------------------
@Local
public interface IHelloWorld {
public String sayHello();
}
---------------The action---------------------
import org.jboss.seam.annotations.Name;
@Name("helloWorld")
public class HelloWorldAction implements IHelloWorld {
public String sayHello() {
return "Hello World!";
}
}
------------The page------------------------
<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml"
xmlns:h="http://java.sun.com/jsf/html"
xmlns:f="http://java.sun.com/jsf/core">
<head>
<title>Hi!</title>
</head>
<body>
<f:view>
<h:outputText value="#{helloWorld.sayHello}"/>
</f:view>
</body>
</html>
Deployment goes fine but when I try to load the sample page JBoss prints
the following:
javax.el.PropertyNotFoundException: Target Unreachable, identifier
'helloWorld' resolved to null

I'm not too confident about my deployment process because (as I said
before) I'm new to this world so JBoss IDE for Eclipse is a dark piece
of software to me, and I did not found a way to deploy the project so I
wrote my own ant's build.xml which is this:
