Hi, I'am using NetBeans5.5 Beta, and latest JBoss 4.0.4GA Patch1. My problem is, when trying to run simple HelloWorld application I have NPE message. What do I do wrong or what should I do more? here is enterprise bean class: package hello; import javax.ejb.Stateless; @Stateless public class HelloBean implements hello.HelloRemote { public HelloBean() {} public String komunikat() { return "HelloWorld"; } } remote interface: package hello; import javax.ejb.Remote; @Remote public interface HelloRemote { public String komunikat(); } application client: package hellojb; import javax.annotation.EJB; import hello.HelloRemote; public class Main { @EJB private static HelloRemote bin; public Main() { } public static void main(String[] args) { System.out.println("HERE: " + bin.komunikat()); //<----this line makes exception } } log: Applicaton Deployed Operation start started run-deploy: run-tool: run-jar: Exception in thread "main" java.lang.NullPointerException at hellojb.Main.main(Main.java:35) Java Result: 1 run-display-browser: run: BUILD SUCCESSFUL (total time: 1 second) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3956932#...
