Need Help Deploying EJB as a Web-Service (Exam Objective 3)

[Avinash Ga]

Hi Ranchers,

I am trying to learn to deploy the EJB as a Web-Service for covering Exam Objective 3 . Since i dont know EJB, i am struck at this objective from past 1 week . Particularly i dont know what to put inside sun-ejb-jar.xml . Can you please review my simple code and tell me what i am missing?

Following is the simple code.

EndPoint Interface :-

package simple;

import javax.ejb.Remote;
import javax.jws.WebMethod;
import javax.jws.WebService;

@Remote
@WebService(name="SimpleServicePortType")
public interface SimpleService {

	@WebMethod
	public String sayHello();
}

Implementation Bean:-

package simple;

import javax.ejb.Remote;
import javax.ejb.Stateless;
import javax.jws.WebService;

@Stateless(name="SimpleServiceBean")
@Remote(SimpleService.class)
@WebService(serviceName="SimpleService", endpointInterface="simple.SimpleService", portName="SimpleServicePort")
public class SimpleServiceBean implements SimpleService{

	public String sayHello() {
		return "Hello";
	}

}

ejb -jar.xml:-

<?xml version="1.0" encoding="UTF-8"?> <ejb-jar version="3.1" 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/ejb-jar_3_1.xsd"> <display-name>SimpleEjbWebService </display-name> <enterprise-beans> <session> <ejb-name>SimpleServiceBean</ejb-name> <service-endpoint>simple.SimpleService</service-endpoint> <ejb-class>simple.SimpleServiceBean</ejb-class> <session-type>Stateless</session-type> <transaction-type>Container</transaction-type> </session> </enterprise-beans> </ejb-jar>

sun-ejb-jar.xml :-

<xml>Really Dont Know What to put here</xml>





Thanks in Advance.....

Hi Avinash,

why do you need ejb -jar.xml and sun-ejb-jar.xml file.

Since you have annotated all the details, this files are not required, I suppose.

Thanks Benneth,

I tried deploying without ejb-jar.xml and sun-ejb-jar.xml and it went through nicely. But i was looking into one of the exam objectives which states that Configure deployment descriptors (ejb-jar.xml, webservices.xml) for transactions, etc. and concerned about that. So do if i am using EJB 3 i can skip those external configurations. So can i expect web services using EJB 3.0 questions in exam? (FYI: Some times when i have an exam to take and only half prepared, i act weirdly {asking silly questions to myself and others} )

Thanks Again
