Okay, I'm about to drink a pint of windshield wiper fluid. If Peter or anyone
else can help me, I'm forever grateful.
I have created a new standard Java project, named
com.acmeco.serverapp.ftp.client, that sits next to the EJB3 app in my Eclipse
workspace.
I have created a jndi.properties file in the build path that has the data Peter
suggested (even though I'm already hardcoding this info in the class itself
below).
I have created a new class in the default package called HelloClientPOJO.java.
Here is the code:
import javax.naming.InitialContext;
| import javax.naming.Context;
| import javax.naming.NamingException;
| import java.util.Properties;
| import javax.rmi.PortableRemoteObject;
|
| import com.acmeco.serverapp.ftp.ejb3.*;
|
| public class HelloClientPOJO {
|
| FTPBean _ftpbean;
|
| public HelloClientPOJO(){
| try{
| Context jndiContext = getInitialContext();
| Object ref =
jndiContext.lookup("com.acmeco.serverapp.ftp.ejb3.FTPBeanRemote");
| _ftpbean = (FTPBean)ref;
| }catch (javax.naming.NamingException ne){
| //nothing
| }
| }
|
| protected void sayHello() {
| _ftpbean.doWork();
| }
|
| public static void main(String [] args)
| {
| HelloClientPOJO helloClient= new HelloClientPOJO();
| helloClient.sayHello();
| }
|
| // developed for JBoss only. this is vender dependency
| public static Context getInitialContext( ) throws
javax.naming.NamingException {
| Properties p = new Properties( );
| p.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
| p.put(Context.URL_PKG_PREFIXES, "
org.jboss.naming:org.jnp.interfaces");
| p.put(Context.PROVIDER_URL, "jnp://localhost:1099");
| return new javax.naming.InitialContext(p);
| }
| }
|
Here is the error on the console when the POJO app runs:
Exception in thread "main" java.lang.NullPointerException
at HelloClientPOJO.sayHello(HelloClientPOJO.java:24)
at HelloClientPOJO.main(HelloClientPOJO.java:30)
I got this from this URL/tutorial:
http://biese.wordpress.com/2008/02/20/how-to-call-ejb3-from-jsp-servlet-and-stand-alone-application/
Neither the server nor the bean(s) have been changed, so my JBoss
startup/deployment log and JNDI info is all the same as before. What am I doing
wrong? What do I need to put into the content lookup to find the bean?
Please help! Once I get this working, I am going to write the world's most
idiot proof Hello World for JBoss 5/EJB 3/Eclipse. I know a LOT of other people
have/had problems with these issues. I want to end the confusion once and for
all.
