Help needed to deploy HelloWorld EJB

[Vasanthi hiremath]

Hi,

I was following the step by step approch given in Beginning EJB3 Application Development book about the EJB3 Hello World deployment. I am deploying the EJB mannually, that is I am nit using any tool. I am new to EJB3. I deployed the bean it was successfull and I am stuck in Client deployment. I deployed the client as given in the book.But I am getting the following error. Could anyone help me why I am getting the error.. I am trying it since 2 days.

com.sun.enterprise.appclient.UserError: Appclient main-class is not found. Plea
se check the main-class entry of your appclient manifest file, the mainclass com
mand-line argument, and your classpath.
java.lang.ClassNotFoundException:

PLSSSSSSSSSSSSSSSSSSSSSSSSS help me.


Many Thanks

See one of my examples, I am using JBoss:

    
package enthuware.session.uno;

import javax.ejb.Remote;

@Remote
public interface SessionUnoRemote {
	void calculaSuma(int a, int b);
}

    
package enthuware.session.uno;

import javax.annotation.PostConstruct;
import javax.ejb.Stateful;
import javax.persistence.PostRemove;
import javax.persistence.PreRemove;

@Stateful
//@Local({SessionUnoLocal.class})
//@Remote({SessionUnoRemote.class})
public class SessionUno implements SessionUnoRemote {

	public SessionUno() {
		System.out.println("Constructor : " + this.getClass().getName());
	}
	@Override
	public void calculaSuma(int a, int b) {
		System.out.println("Suma : " + (a+b));
	}	
	@PostConstruct
	public void postConstruct() {
		System.out.println("PostConstruct : " + this.getClass().getName());
	}
	@PreRemove
	public void preRemove() {
		System.out.println("PreRemove : " + this.getClass().getName());
	}
	@PostRemove
	public void postRemove() {
		System.out.println("PostRemove : " + this.getClass().getName());
	}
}

And client:

    
package enthuware.session.uno.cliente;

import javax.naming.Context;
import javax.naming.InitialContext;

import enthuware.session.uno.SessionUnoRemote;

public class SessionUnoCliente {

	/**
	 * @param args
	 */
	public static void main(String[] args) throws Exception {
		 // JBoss' default remote jndi: <ejb-name>/remote
		 final String jndiName = "SessionUno/remote";
		 Context ic = new InitialContext();
		 Object obj = ic.lookup(jndiName);

		 SessionUnoRemote session = (SessionUnoRemote)obj;
		 
		 session.calculaSuma(1, 10);
	}

}

The jndi.properties file:

   
java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory
java.naming.factory.url.pkgs=org.jboss.naming:org.jnp.interfaces
java.naming.provider.url=127.0.0.1\:1099

Hope it helps...

Hi,

Actually in my EJB I am not using the JNDI properties, is it must?? if so then where will I put that file & how to deply it... please tell me...

kind regards
vasanthi

[Vasanthi hiremath]

Hello I am waiting for some reply, please help me. My code looks like this

Remote interface

package helloworld.ejb;
import javax.ejb.Remote;
@Remote
public interface HelloWorld {
public String outputHelloWorld();
}

Bean class


package helloworld.ejb;
import javax.ejb.Stateless;
@Stateless
public class HelloWorldBean implements helloworld.ejb.HelloWorld {
public String outputHelloWorld() {
return "Hello World!";
}
}


And my client

package helloworld.client;
import javax.ejb.EJB;
import helloworld.ejb.HelloWorld;
public class HelloWorldClient {
@EJB
private static HelloWorld helloWorld;
public static void main (String[] args)
{
System.out.println(helloWorld.outputHelloWorld());
}
}

Manifest file

Manifest-Version: 1.0
Main-Class: helloworld.client.HelloWorldClient

And the last application.xml


<?xml version="1.0" encoding="UTF-8"?>
<application version="5" xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee
http://java.sun.com/xml/ns/javaee/application_5.xsd">
<display-name>helloworldejb</display-name>
<module>
<ejb>helloworldejb.jar</ejb>
</module>
<module>
<java>helloworldclient.jar</java>
</module>
</application>


I have been working on it more than a week, I am not able to continue my study as I am stuck , I am not using any JNDI properties file I would really appriciate an early response. The server I am using is glassfish & I am not using an IDE.

Hi Vasanthi,

Since you are trying to access EJB3 from outside (I mean outside of EJB container) you need to use JNDI look up to get a reference of the bean. Refer to the previous reply for the code example. If you access EJB from servlet which deployed in the same container you can use DI. Or else you need to use look up.

Hope this helps.

[Vasanthi hiremath]

Hi Sai,

I took this example from Beginning EJB3 Application Development book, in that the author has not told anything about the JNDI look up. So if I have to call EJB from a stand alone java application should I have to user JNDI look up?? Also i don't know where to store the file during the package and also how to write the JNDI properties, is there any link where I get the step by step approach.

Many Thanks
Vasanthi

Hello Vasanthi,

The following link may help you.

http://www.webagesolutions.com/knowledgebase/javakb/jkb005/index.html

and yes, since client is outside the EJB container we need to use JNDI look up and no need for any properties. You can use annotations approach for JNDI lookup. Look at the above link.

[Vasanthi hiremath]

Finally I am successfull....

Thanks a tonn Sai Surya...

Kind Regards
vasanthi
