Question

没有创建实体bean
我用的是weblogic,jbuilder,sql2000
bean代码如下：
Employees.java:
package cmpdemo;import javax.ejb.*;
import java.util.*;
import java.sql.*;public interface Employees extends javax.ejb.EJBLocalObject
{
    public Integer getEmployeeID();
    public void setLastName(String lastName);
    public String getLastName();
    public void setFirstName(String firstName);
    public String getFirstName();
    public void setTitle(String title);
    public String getTitle();
    public void setTitleOfCourtesy(String titleOfCourtesy);
    public String getTitleOfCourtesy();
    public void setBirthDate(Timestamp birthDate);
    public Timestamp getBirthDate();
    public void setHireDate(Timestamp hireDate);
    public Timestamp getHireDate();
    public void setAddress(String address);
    public String getAddress();
    public void setCity(String city);
    public String getCity();
    public void setRegion(String region);
    public String getRegion();
    public void setPostalCode(String postalCode);
    public String getPostalCode();
    public void setCountry(String country);
    public String getCountry();
    public void setHomePhone(String homePhone);
    public String getHomePhone();
    public void setExtension(String extension);
    public String getExtension();
    public void setPhoto(byte[] photo);
    public byte[] getPhoto();
    public void setNotes(String notes);
    public String getNotes();
    public void setReportsTo(Integer reportsTo);
    public Integer getReportsTo();
