EJB Learning (ii)--Creating the first EJB project with Eclipse+jboss

1. Environment configuration

· Eclipse Luna Service Release 1 (4.4.1)

· JBOSS as 5.0

· Java 1.8.0_25

2. Create an EJB project

Click File → New → EJB project, and fill in the project name as follows:

Then click Next → Finish;

Select the Ejbmodule folder under the EJB project and right-click → New→ Session bean (EJB 3.X) to create a session bean.

Hellowrold Interface:

Package Com.tgb.ejb;public interface HelloWorld {public string SayHello (string name);}

Hellowroldbean Implementation class:

Package Com.tgb.ejb;import javax.ejb.remote;import javax.ejb.stateless;/** * Session Bean Implementation class HelloWorld */@Stateless @remote ({helloworld.class}) public class Helloworldbean implements HelloWorld {@Overridepublic String SayHello (string name) {return name+ "Welcome to use ejb3.0~~";}}

3. Deployment

There are two ways of deploying:

① released in Eclipse

In the previously created server, right-click Add and Remove, and then start the project.

② is packaged and then deployed to the specified server

On the project right → Export→ EJB JAR file, select the JBOSS Server deployment directory: Jboss_home/server/defau Lt/deploy, complete.

4. Create a client

①  Click File→new→other ... →java Project

② Add a reference to the above Ejb_01.jar and the JBoss Client jar package ( $JBOSS _home/clent/jbossall-clent.jar), add to the classpath path.

③ Write the client test class, the code is as follows

Package Com.tgb.ejb.client;import Javax.naming.initialcontext;import Javax.naming.namingexception;import Com.tgb.ejb.helloworld;public class Client {public static void main (string[] args) throws Namingexception { InitialContext InitialContext = new InitialContext (); HelloWorld EJB = (HelloWorld) initialcontext.lookup ("Helloworldbean/remote"); String name = Ejb.sayhello ("Zhoujiang"); SYSTEM.OUT.PRINTLN (name);}}

5. Running the client

Start JBoss first;

Run the client code to prove our remote call succeeded.
