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.Column;
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;
import javax.persistence.Entity;
import javax.persistence.GeneratedValue;
import javax.persistence.GenerationType;
import javax.persistence.Id;
import javax.persistence.JoinColumn;
import javax.persistence.ManyToOne;
import javax.persistence.Column;
import javax.persistence.Table;
import javax.persistence.FetchType;
import javax.persistence.ManyToMany;
import javax.persistence.CascadeType;
import javax.persistence.PostPersist;
import java.util.Set;
//@Entity
public class Employee implements java.io.Serializable
{
private Long id;
private String lsName;
private int liAge;
private String lsSex;
private Department department;
public Employee()
{
}
//@Id(generate = GeneratorType.IDENTITY)
// @Id @GeneratedValue(strategy=GenerationType.IDENTITY)
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;
}
// @Column(name = "AGE")
public int getAge()
{
return liAge;
}
public void setAge(int liAge)
{
this.liAge = liAge;
}
// @Column(name = "SEX")
public String getSex()
{
return lsSex;
}
public void setSex(String lsSex)
{
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....
