EJB3.0 - java.lang.reflect.UndeclaredThrowableException problem

[Marian Mroz]

Hi I've got a problem with run simple EJB3.0 application

I've got an interface:

package pl.edu.mmroz;

public interface Calculator {
	public String echo(String s);
}  

and EJB Bean implementation:

package pl.edu.mmroz;
import javax.ejb.Remote;
import javax.ejb.Stateless;

@Stateless()
@Remote( { Calculator.class })
public class CalculatorBean implements Calculator {
	public String echo(String s) {
		return s.concat("test");
	}

} 

and I complie it with using jdk6

I put it on JBoss 4.2.3.GA with jre1.5.0_16

On the server there is an information that it started:
12:27:20,328 INFO [EJBContainer] STARTED EJB: pl.edu.mmroz.CalculatorBean ejbName: CalculatorBean

When I'm try run simple test application:

package pl.edu.mmroz;

import java.util.Properties;

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

import pl.edu.mmroz.Calculator;

public class CalculatorBeanTest {
	public static void main(String[] args) {

		Properties properties = new Properties();

		properties.put("java.naming.factory.initial",
				"org.jnp.interfaces.NamingContextFactory");

		properties.put("java.naming.factory.url.pkgs",
				"org.jboss.naming rg.jnp.interfaces");

		properties.put("java.naming.provider.url", "localhost:1099");

		Context context = null;
		try {
			context = new InitialContext(properties);
		} catch (NamingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

		Calculator calculator = null;
		try {
			calculator = (Calculator) context.lookup("CalculatorBean/remote");
		} catch (NamingException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}

		System.out.println("Hello World: "
				+ calculator.echo(new String("Test string")));
	}
}
   

I receive following error:

Does anybody know what is the reason of this exception?

Are you using the correct version of JBoss jar files in your client classpath? You should be placing the exact same jbossall-client.jar file from the %JBOSS_HOME%/client folder, in the client classpath.

Thanks for help. It was a problem - there was a different access to jbossall-client.jar (it was set jbossall-client-3.2.3.jar)
