Dear All,
I am new to EJB 3.0. I created a Hello EJB 3.0. I am using the JBoss Eclipse
IDE 3.1.2 and jboss-EJB-3.0_RC5-PFD.zip for EJB3 support on JBoss 4.0.3.
For deployement, I created the jar of Remote Interface + Stateless session bean
and the client. The code is attached with this mail.
When I deploy the jar file, i am getting the following exception.
Please help.
----------------------------
//HelloWorldBean.java
----------------------------
package com.ebw.ejb3;
import javax.ejb.Remote;
import javax.ejb.Stateless;
public @Stateless @Remote class HelloWorldBean implements HelloWorld {
public void sayHello(String name) {
if (name == null) {
System.out.println("I am NULL but EJB 3 is working");
} else {
System.out.println("Hello "+name);
}
}
}
----------------
HelloWorld
----------------
package com.ebw.ejb3;
import javax.ejb.Remote;
@Remote
public interface HelloWorld {
public void sayHello(String name);
}
--------------------------------
HelloWorldClient
--------------------------------
package com.ebw.client;
import java.util.Hashtable;
import javax.annotation.EJB;
import javax.naming.InitialContext;
import com.ebw.ejb3.HelloWorld;
public class HelloWorldClient {
private @EJB static HelloWorld helloWorld;
public static void main(String[] arg) {
try {
HelloWorldClient client = new HelloWorldClient();
client.testMe(arg);
} catch (Exception e) {
e.printStackTrace();
}
}
public void testMe(String[] arg) {
try {
System.out.println("helloWorld=" + helloWorld + "\n");
helloWorld.sayHello(arg[0]);
} catch (Exception e) {
e.printStackTrace();
}
}
}
