  1. Right Click under the Project Explorer and Create a EJB project as shown.





  2. On the next screen give the project name as StatelessSessionEJB.





  3. Right Click on ejbModule and create a new Interface RegisterBeanRemote





  4. On the New Java Interface window give the package name as statelessejb and Interface name as RegisterBeanRemote





  5. Populate the RegisterBeanRemote interface with the following code.
    Code Block
    titleRegisterBeanRemote.java
    borderStylesolid
    package statelessejb;
import javax.ejb.Remote;
@Remote
public interface RegisterBeanRemote 
{
public void register(String FirstName, String LastName, String Sex, String UserName, String Password);
public boolean verify(String username, String password);
}
  6. Right Click on StatelessSessionEJB project and create a new class RegisterBean as shown in the figure





  7. Populate the class RegisterBean with the following data
    Code Block
    titleRegisterBean.java
    borderStylesolid
    package statelessejb;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import javax.annotation.PostConstruct;
import javax.annotation.PreDestroy;
import javax.annotation.Resource;
import javax.ejb.Stateless;
import javax.sql.DataSource;
@Stateless
public class RegisterBean implements RegisterBeanRemote{
	@Resource(name="jdbc/userds")
	private DataSource dbsource;
	private Connection dbconnect;
	@PostConstruct
	public void initialize()
	{
		try{
			dbconnect= dbsource.getConnection();
		}
		catch(Exception e)
		{
			e.printStackTrace();
		}
	}
	public void register(String FirstName, String LastName, String Sex, String UserName, String Password)
	{
		try
		{
			String insert="INSERT INTO USERINFO (" + "FIRSTNAME," + "LASTNAME," + "SEX," + "USERNAME," + "PASSWORD)" + " VALUES(?,?,?,?,?)";
			PreparedStatement ps=dbconnect.prepareStatement(insert);
			ps.setString(1, FirstName);
			ps.setString(2, LastName);
			ps.setString(3, Sex);
			ps.setString(4, UserName);
			ps.setString(5, Password);
			int rs =ps.executeUpdate();
		}
		catch(Exception e)
		{
			e.printStackTrace();
		}
	}
	public boolean verify(String username, String password)
	{
		boolean ret=false;
		String select="SELECT * FROM USERINFO";
		System.out.println(select);
		try{
		PreparedStatement ps=dbconnect.prepareStatement(select);
		ResultSet rs= ps.executeQuery();
		while(rs.next())
		{
			String str=(rs.getString("USERNAME")).trim();
			String str1=(rs.getString("PASSWORD")).trim();
			if (str.compareTo(username)==0)
			{
			if(str1.compareTo(password)==0)
				ret=true;
			else
			    ret=false;
			}
			else
				ret=false;
		}
		}
		catch(Exception e)
		{
			e.printStackTrace();
		}
		return ret;	
	}
	@PreDestroy
	public void destroy(){
		try
		{
		dbconnect.close();
		dbconnect=null;
		}
		catch(Exception e)
		{
			e.printStackTrace();
		}

	}
}
    Next we will try to understand the code
