Salve a tutti. Premetto che adesso sto conoscendo gli EJB.
Ho preso un esempio per farlo girare sotto JBoss riguardante la somma tra due numeri.
codice:Adder.java import java.rmi.RemoteException; import javax.ejb.EJBLocalObject; public interface Adder extends EJBLocalObject { public int add(int a, int b) throws RemoteException; } AdderBean.java /* * To change this template, choose Tools | Templates * and open the template in the editor. */ import javax.ejb.*; public class AdderBean implements SessionBean { public void setSessionContext(SessionContext aContext) { } public void ejbActivate() { } public void ejbPassivate() { } public void ejbRemove() { } public int add(int a, int b) { System.out.println("AdderBean esegue"); return (a+b); } public void ejbCreate() { } } AdderHome.java import java.rmi.RemoteException; import javax.ejb.CreateException; import javax.ejb.EJBLocalHome; public interface AdderHome extends EJBLocalHome { Adder create() throws RemoteException,CreateException; } ejb-jar.xml <?xml version="1.0" encoding="UTF-8"?> <ejb-jar version="2.1" xmlns="http://java.sun.com/xml/ns/j2ee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/ejb-jar_2_1.xsd"> <enterprise-beans> <session> <display-name>Adder</display-name> <ejb-name>Adder</ejb-name> <local-home>AdderHome</local-home> <local>Adder</local> <ejb-class>AdderBean</ejb-class> <session-type>Stateless</session-type> <transaction-type>Bean</transaction-type> </session> </enterprise-beans> </ejb-jar>
Adesso ho creato Adder.jar e lo inserisco nella cartella all\deploy dove il jar contiene una cartella classes con i .class e una META-INF con ejb-jar.xml.
Il deploy automatico mi dà questo errore:
