[Java] Problema JEE

[mux85]

Sto facendo un progetto in JEE per l'università. Non ho mai usato JEE prima e quindi stavo facendo qualche prova. Uso eclipse for JEE developer e JBoss. questo è il piccolo pezzo di codice che ho scritto per il client.

import java.util.Properties;
import com.AgriNet.controlli.*;
import javax.naming.*;

public class Main {
	public static Context getInitialContext() throws javax.naming.NamingException {
		System.out.println("2");
		Properties properties = new Properties();
		properties.put("java.naming.factory.initial","org.jnp.interfaces.NamingContextFactory");
		properties.put("java.naming.factory.url.pkgs","org.jboss.naming:org.jnp.interfaces");
		properties.put("java.naming.provider.url","localhost");
		return new javax.naming.InitialContext(properties);
	}

	public static void main(String[] args) {
		try {
			System.out.println("1");
			Context jndiContext = getInitialContext();
			Object ref = jndiContext.lookup("ProvaRemote");
			System.out.println("3");
			ProvaRemote pr=(ProvaRemote) ref;
			System.out.println("4");
			pr.prova();
			System.out.println("6");
		}
		catch(Exception e){e.printStackTrace();}
	}

}

questo invece è il codice del bean

import javax.ejb.*;
import javax.persistence.*;
import com.AgriNet.entità.*;
import org.jboss.annotation.ejb.RemoteBinding;

@Stateless
@RemoteBinding(jndiBinding="ProvaRemote")
public class ProvaBean implements ProvaRemote{
	@PersistenceContext(unitName="agrinet")
	private EntityManager manager;
	public void prova(){
		Cliente cl=new Cliente();
		cl.setId(10);
		cl.setNome("mario");
		manager.persist(cl);
		System.out.println("5");
	}
	
}

è questo quello dell'interfaccia remote

import javax.ejb.*;

@Remote
public interface ProvaRemote {
	public void prova();
}

ora l'errore che ricevo

javax.naming.NameNotFoundException: ProvaRemote not bound

io non capisco proprio dove sta il problema. qualcuno mi da una mano?
grazie

già che ci sono vi posto i file persistence.xml e il file per configurare il data source

persistence.xml (contenuto nella cartella ejb-module\meta-inf del progetto del server)

<?xml version="1.0" encoding="UTF-8" ?> 
<persistence>
 <persistence-unit name="agrinet">
  <jta-data-source>java:/MySqlDS</jta-data-source> 
  <properties>
   <property name="hibernate.hbm2ddl.auto" value="create-drop" /> 
  </properties>
 </persistence-unit>
</persistence>

agrinet-ds.xml (nella cartella server\default\deply di JBoss)

<?xml version="1.0" encoding="UTF-8" ?> 
<datasources>
 <local-tx-datasource>
  <jndi-name>MySqlDS</jndi-name> 
  <connection-url>jdbc:mysql://localhost:3306/agrinetdb</connection-url> 
  <driver-class>com.mysql.jdbc.Driver</driver-class> 
  <user-name>root</user-name> 
  <password>agrinetpass</password>

  <metadata>
   <type-mapping>mySQL</type-mapping> 
  </metadata>
 </local-tx-datasource>
</datasources>

per finire posto il log di JBoss (la parte interessante dovrebbe essere in fondo, sembra proprio che ci sia qualcosa che non va ma non capisco cosa)

ho provato anche rifare da zero l'installazione e la configurazione di jboss e la creazione del progetto ma il problema rimane identico

[mux85]

ah dimenticavo la classe Cliente è un entity bean con il seguente codice

import java.io.Serializable;
import javax.persistence.*;
import java.util.Date;

@Entity
@Table (name="clienti")
public class Cliente implements Serializable{

	private static final long serialVersionUID = 1L;
	
	private int id;
	private String nome;
	private String cognome;
	private Date dataNascita;
	
	@Id
	@Column(name="id")
	public int getId() {
		return id;
	}
	
	public void setId(int id) {
		this.id = id;
	}
	
	@Column(name="nome")
	public String getNome() {
		return nome;
	}
	
	public void setNome(String nome) {
		this.nome = nome;
	}
	
	@Column(name="cognome")
	public String getCognome() {
		return cognome;
	}
	
	public void setCognome(String cognome) {
		this.cognome = cognome;
	}
	
	@Column(name="data_nascita")
	public Date getDataNascita() {
		return dataNascita;
	}
	
	public void setDataNascita(Date dataNascita) {
		this.dataNascita = dataNascita;
	}
	

}

eheh questa discussione è più che altro un monologo. cmq ho risolto e ovviamente era problema stupido. semplicemente il file persistence.xml era fatto nel modo giusto e messo nella cartella giusta ma andava anche importato nel progetto in eclipse. io pensavo che lo trovasse in automatico
