Hi guys,
I am investigating how useful EJB can be for the product for which I am the
architect. I know just the big picture of EJB. Downloaded jBoss, and
guess how pleased I was to see it running immediately. Wrote a simple Hello
World example, and could _deploy_ it successfully immediately too.
Happiness!
Running Solaris, JDK1.3, jBoss-2.0-FINAL.
Enter: dark clouds
I have been trying for DAYS now to run my client. I've tried modifying the
ejb-jar.xml. I've tried changing names of packages. I've tried adding a
jboss.xml file. I've tried many ways to write the client. It just won't
run. (I've searched the archive of this list, but didn't find anything
similar.)
I get this when I deploy it:
+++++++++++++++

Is that correct?
Then when I run my client, I get this error:
++++++++++++++++++
javax.naming.NameNotFoundException: parfo.HelloHome not bound

My ejb-jar.xml looks like this:
+++++++++++++
<?xml version="1.0" encoding="Cp1252"?>
<ejb-jar>
<description>Lek med beans</description>
<display-name>TestAvBeans</display-name>
<enterprise-beans>
<session>
<ejb-name>parfo.Hello</ejb-name>
<home>parfo.HelloHome</home>

<ejb-class>parfo.HelloBean</ejb-class>
<session-type>Stateless</session-type>
<transaction-type>Bean</transaction-type>
</session>
</enterprise-beans>
</ejb-jar>
++++++++++++++++++
My client code looks like this:
++++++++++++++
import parfo.*;
import javax.ejb.*;
import javax.naming.*;
import javax.rmi.*;
import java.util.*;
public class HelloClient {
public static void main(String[] args) {
try {
System.setProperty("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory");
System.setProperty("java.naming.provider.url",
"localhost:1099");
Properties props = System.getProperties();
System.out.println("Got props");
Context ctx = new InitialContext(props);
System.out.println("Got context");
Context context = new InitialContext();
Object boundObject = context.lookup("java:parfo.HelloHome");
HelloHome helloHome = (HelloHome) PortableRemoteObject.narrow(
boundObject, HelloHome.class);
Hello _hello = helloHome.create();
HelloHome home;
home = (HelloHome) ctx.lookup("java:parfo/HelloHome");
System.out.println("Got home object #1");
home = (HelloHome) ctx.lookup("HelloHome");
System.out.println("Got home object #2");
home = (HelloHome) PortableRemoteObject.narrow(
ctx, HelloHome.class);
System.out.println("Got home object #3");
Hello hello = home.create();
System.out.println(hello.hello());
hello.remove();
}
catch (Exception e) {
e.printStackTrace();
}
}
}
++++++++++++
and even though I try different ways to get the reference to the Home
object, none of them work (I comment out different ones to test.)
Any ideas?
Kind regards
Pär
