一本关于JBuilder 应用开发的书籍,希望大家喜欢,其实我没看过的,

package datasession;
import java.rmi.*;
import javax.ejb.*;
import com.borland.dx.sql.dataset.*;
public class DataSession implements SessionBean 
{
  private SessionContext sessionContext;
//生成Database的对象
  Database database1 = new Database();
//生成QueryDataSet的对象
  QueryDataSet queryDataSet1 = new QueryDataSet();

  {
  }
  public void ejbRemove() throws RemoteException 
  {

  public void ejbActivate() throws RemoteException 
  {

  public void ejbPassivate() throws RemoteException 
  {
  }
  public void setSessionContext(SessionContext sessionContext) throws RemoteException 
  {
    this.sessionContext = sessionContext;
  }
  public DataSession() 
  {
    try 
    {
      jbInit();
    }
    catch(Exception e) 
    {
      e.printStackTrace();
    }
  }
  private void jbInit() throws Exception 
  {
	//queryDataSet1和database1相关联
    queryDataSet1.setQuery(new com.borland.dx.sql.dataset.QueryDescriptor(database1, "", null, true, Load.ALL));
	//database1和Access数据库相关联
    database1.setConnection(new com.borland.dx.sql.dataset.ConnectionDescriptor("jdbc:odbc:AccessDsn", "", "", false, "sun.jdbc.odbc.JdbcOdbcDriver"));
  }
}
