Have you read the stacktrace? Which indicates you are trying to load web based classes in a now web based test. Read the documentation on how to be able to test web based things

EJB persistence not working

I have a example EJB persistence with EJB module run on Jboss 5GA , JDK 6 . Default package have 3 file :
Book.java :

public class Book implements Serializable{
private int id;
private String name;
public Book(){

#Id
#GeneratedValue(strategy= GenerationType.IDENTITY)
#Column(name="id")
public int getId() {
return id;
}
public void setId(int id) {

How to resolve these error ? thanks you so much !

"$JBOSS_HOME/jboss-as/client/jnp-client.jar" contains the missing class "org.jnp.interfaces.NamingContextFactory" , The "jnp-client.jar" is referred internally using the MANIFEST.MF file "class-path" entry of the "$JBOSS_HOME/client/jbossall-client.jar" file.
So the JBoss Client code users/developers need to make sure that in order to avoid the "[Caused by: java.lang.ClassNotFoundException: org.jnp.interfaces.NamingContextFactory]" exception users must include the "$JBOSS_HOME/client/jbossall-client.jar" in client's classpath.

If I remove the annotation profiles and classes that use the annotation inicializer function normally,
How do I solve this?

I solved the problem by moving the database configuration classes to load along with the root settings
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] {ThymeleafConfig.class};
}
#Override
protected Class<?>[] getServletConfigClasses() {
return new Class[] {ThymeleafConfig.class,ProdProfileDatabase.class,DevProfileDatabase.class,TestPr ofileDatabase.class};
}
I did this exchange
#Override
protected Class<?>[] getRootConfigClasses() {
return new Class[] {ProdProfileDatabase.class,DevProfileDatabase.class,TestPr ofileDatabase.class};
}
#Override
protected Class<?>[] getServletConfigClasses() {
return new Class[] {ThymeleafConfig.class};
}

I thought that the problems is the path:
Parent root = FXMLLoader.load(RestClient.class.getResource("/fxml/productComponent.fxml"));
but I read this:

Not able to call ejb on same machine using client class

I am new to EJB. I tried an example from java_for_web_with_servlets_jsp_and_ejb book. The following code creates an session been called Adder which adds two integers:
Adder.java:
package com.brainysoftware.ejb;
import java.rmi.RemoteException;
import javax.ejb.EJBObject;
public interface Adder extends EJBObject{
public int add(int a,int b) throws RemoteException;
}
AdderBean.java
package com.brainysoftware.ejb;
import java.rmi.RemoteException;
import javax.ejb.EJBException;
import javax.ejb.SessionBean;
import javax.ejb.SessionContext;
public class AdderBean implements SessionBean{
public int add(int a, int b){
System.out.println("From AdderBean");
return (a+b);
}
#Override
public void ejbActivate() throws EJBException, RemoteException {
// TODO Auto-generated method stub
}
#Override
public void ejbPassivate() throws EJBException, RemoteException {
// TODO Auto-generated method stub
}
#Override
public void ejbRemove() throws EJBException, RemoteException {
// TODO Auto-generated method stub
}
#Override
public void setSessionContext(SessionContext arg0) throws EJBException,
RemoteException {
// TODO Auto-generated method stub
}
}
AdderHome.java
package com.brainysoftware.ejb;
import java.rmi.RemoteException;
import javax.ejb.CreateException;
import javax.ejb.EJBHome;
public interface AdderHome extends EJBHome{
Adder create() throws RemoteException, CreateException;
}
The deployment descriptor is as follows:
<?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">

I created a jar file of this project and placed the jar in the tomcat's lib.
Now, for the client I created a dynamic web project having the class BeanClient.java that uses the Adder bean:
import java.rmi.RemoteException;
import java.util.Properties;
import javax.ejb.CreateException;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.naming.NamingException;
import com.brainysoftware.ejb.Adder;
import com.brainysoftware.ejb.AdderHome;
import javax.rmi.PortableRemoteObject;
public class BeanClient {
public static void main(String[] args){
Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
props.put(Context.PROVIDER_URL, "localhost:1099");
try{
InitialContext jnic = new InitialContext(props);
System.out.println("Get context");
Object ref = jnic.lookup("Adder");
System.out.println("Got reference");
AdderHome home = (AdderHome) PortableRemoteObject.narrow(ref,AdderHome.class);
Adder adder = home.create();
System.out.println("Adding 2 and 5:"+adder.add(2,5));
} catch(NamingException e){
System.out.println(e.toString());
} catch(CreateException e){
System.out.println(e.toString());
} catch (RemoteException e) {
System.out.println(e.toString());
}
}
}
On executing this class in eclipse, I get the following error:
Get context
javax.naming.CommunicationException: Could not obtain connection to any of these urls: localhost:1099 and discovery failed with error: javax.naming.CommunicationException: Receive timed out [Root exception is java.net.SocketTimeoutException: Receive timed out] [Root exception is javax.naming.CommunicationException: Failed to connect to server localhost:1099 [Root exception is javax.naming.ServiceUnavailableException: Failed to connect to server localhost:1099 [Root exception is java.net.ConnectException: Connection refused: connect]]]
Could you please help me out with this?

to look up and ejb firstbale :
you must have an interface and it's implementation.
you have to annotate your interface (#Local ou #Remote)
The implementation must be annotated #statless ou #statful
You have to add on you project a jndi.properties.
your ejb project must be deployed on your server to be easy to look up it.
i have for you an example with jboss here :
https://www.youtube.com/watch?v=mBwgHuBg96g
i hope that my answer is useful pour you
