Hi,

I am having a problem with EJB 3.0 . I am using
EJB-3.0_RC9-FD
jboss-4.0.4.GA
jdk 1.5
ant 1.6.5
I am using the hypersonic database of jboss and I want to create two tables in the database Department and Emplyee.


The code for client.java

package com.abcd.EJB3.application;

import com.infosys.EJB3.application.FacadeRemote;
import javax.naming.InitialContext;
import java.sql.Timestamp;

public class client
{
public static void main(String[] args)
{
try
{
InitialContext ctx = new InitialContext();
FacadeRemote lFacadeRemote = (FacadeRemote) ctx.lookup(FacadeRemote.class.getName());

lFacadeRemote.createDepartment("Finance");
lFacadeRemote.createDepartment("Administration");
lFacadeRemote.createDepartment("Sales");

lFacadeRemote.assignEmployeeToDepartment(new Long(1),"Brijesh",31,"M");
lFacadeRemote.assignEmployeeToDepartment(new Long(1),"xxxx",31,"M");
lFacadeRemote.assignEmployeeToDepartment(new Long(2),"yyyy",31,"M");

}
catch(Exception ex)
{
System.out.println(ex);
}
}
}



The code for department.java

package com.abcd.EJB3.application;

import java.util.ArrayList;
import java.util.Collection;

import javax.persistence.CascadeType;

import javax.persistence.Entity;
import javax.persistence.FetchType;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.OneToMany;
import javax.persistence.Table;

@Entity
@Table(name = "DEPARTMENT")
public class Department implements java.io.Serializable
{
private Long id;
private String lsName;
private Collection lEmployees;

//@Id(generate = GeneratorType.AUTO)
@Id @GeneratedValue(strategy=GenerationType.AUTO)

public Long getId()
{
return id;
}

public void setId(Long id)
{
this.id = id;
}

@Column(name = "NAME")
public String getName()
{
return lsName;
}

public void setName(String asName)
{
this.lsName = asName;
}

@OneToMany(cascade = CascadeType.ALL, fetch = FetchType.EAGER, mappedBy="department")
public Collection getEmployees()
{
return lEmployees;
}

public void setEmployees(Collection aEmployees)
{
this.lEmployees = aEmployees;
}

public void addEmployee(String asName,int aiAge, String asSex)
{
if(lEmployees== null)
lEmployees = new ArrayList();

Employee lEmployee = new Employee();
lEmployee.setName(asName);
lEmployee.setAge(aiAge);
lEmployee.setSex(asSex);
lEmployee.setDepartment(this);
lEmployees.add(lEmployee);

setEmployees(lEmployees);
}
}


the code for Employee.java

package com.abcd.EJB3.application;

public Employee()

//@Id(generate = GeneratorType.IDENTITY)
// @Id @GeneratedValue(strategy=GenerationType.IDENTITY)
public Long getId()

public void setId(Long id)

{
this.lsSex = lsSex;
}

// @ManyToOne
// @JoinColumn(name="DEPARTMENT_ID")
public Department getDepartment()
{
return department;
}

public void setDepartment(Department aDepartment)
{
this.department = aDepartment;
}

// @PostPersist
public void samplePostPersist()
{
System.out.println("Added Employee having name = "+ this.getName() +" and Age = "+ this.getAge());
}
}


code for FacadeBean

package com.abcd.EJB3.application;

import javax.ejb.Stateless;
import javax.ejb.Remote;
import javax.persistence.EntityManager;
import javax.persistence.PersistenceContext;

import com.infosys.EJB3.application.Department;
import com.infosys.EJB3.application.Employee;

import java.util.Set;

@Stateless
public class FacadeBean implements FacadeRemote
{
@PersistenceContext
private EntityManager manager;

public void createDepartment(String deptName)
{
Department department = new Department();

department.setName(deptName);

manager.persist(department);

}

public void assignEmployeeToDepartment(Long id, String name, int age, String sex)
{
Department department = searchDepartment(id);

department.addEmployee(name, age, sex);

manager.persist(department);
}

public Department searchDepartment(Long id)
{
return manager.find(Department.class,id);
}

}


code for FacadeRemote


package com.abcd.EJB3.application;

import javax.ejb.Remote;

@Remote
public interface FacadeRemote
{
public void createDepartment(String deptName);
public Department searchDepartment(Long id);
public void assignEmployeeToDepartment(Long id, String name, int age, String sex);
}



now I have compiled the code and deployed it. But when I try to run the code I get the following error:


NameNotFoundException ----- FacadeRemote not bound.

I think its something related to JNDI binding.. but here since I am using EJB 3.0, i dont have to use ejb-jar.xml, but then how does this happens?? what should I do... Please help....
