Contoh EJB 3, Maven, GlassFish & Struts 2

Yach.. buat arsip aja. contoh kecil dari project EJB3 dan Struts2 make maven buildnya :), trus pake GlassFish untuk deploy dan di tampilkan di browser.

Pertama untuk Project EJB3 nya class2nya antara lain

• RemovableRemote

import javax.ejb.Remote;

/**
*
* @author bastomi
*/
@Remote
public interface RemovableRemote {
   public String remove(String message);

}

• RemovableBean

import javax.ejb.Stateless;

/**
*
* @author bastomi
*/
@Stateless(name="RemovableBean", mappedName="ejb/Removable")
public class RemovableBean implements RemovableRemote{

   public String remove(String message){
       return message;
   }
}

• pom.xml nya kayak gini

<?xml version="1.0" encoding="UTF-8"?><project>
 <modelVersion>4.0.0</modelVersion>

 <artifactId>EJBLatihan</artifactId>

           <scope>compile</scope>
       </dependency>
   </dependencies>
</project>

untuk project Clientnya kita make Struts2. file2nya kayak gini

main
---java
|----latihan
|----HelloWorld.java
|----RemovableClient.java
---resource
|-----struts.xml
---webapp
|-----index.jsp
|-----WEB-INF
| |----web.xml
|-----latihan
|----HelloWorld.jsp

• HelloWorld.java

package latihan;

import com.opensymphony.xwork2.Action;
import com.opensymphony.xwork2.ActionSupport;

/**
* Set welcome message.
*/
public class HelloWorld extends ActionSupport {

   public String execute() throws Exception {
      // setMessage(getText("nama"));
    RemovableClient rem=new RemovableClient();
   
    setMessage(rem.getRemote());
       return Action.SUCCESS;
   }

   /**
    * Provide default valuie for Message property.
    */
   public static final String MESSAGE = "PesanQ";

   /**
    * Field for Message property.
    */
   private String message;

   /**
    * Return Message property.
    *
    * @return Message property
    */
   public String getMessage() {
       return message;
   }

   /**
    * Set Message property.
    *
    * @param message Text to display on HelloWorld page.
    */
   public void setMessage(String message) {
       this.message = message;
   }
}

• RemovableClient

package latihan;

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

/**
*
* @author bastomi
*/
public class RemovableClient {

public RemovableClient(){

}

public String getRemote(){
 Context ctx = null;
 RemovableRemote removable = null;
 try {
  ctx = new InitialContext();
  removable = (RemovableRemote) ctx.lookup("ejb/Removable");
 } catch (NamingException e) {
  return e.getMessage()+"==>"+e.toString();
  // TODO Auto-generated catch block
  //e.prinmvntStackTrace();
 }
 if(removable==null){
  return "Kosong";
 }else
  return removable.remove("Look at the server's log");

}
 
}
