 2 这是访问oracle的

 
 
          factory
      org.apache.commons.dbcp.BasicDataSourceFactory
        maxActive100    maxIdle30    maxWait10000    usernameSYSTEM    passwordMANAGER    driverClassNameoracle.jdbc.driver.OracleDriver    urljdbc:oracle:thin:@ibmserver:1521:ORCL 

 

这里的ORCL为SID,注意大小写，用大写

 

 

程序中使用数据源的方法

 static public class ViewJqfkActionListener extends ExoActionListener {
  public void execute(ExoActionEvent event) throws Exception {
   String yhh = event.getParameter(OBJECTID);
   UIListYhda uiList = (UIListYhda) event.getComponent();
   UIJqfk uiJqfk = (UIJqfk) uiList.getSibling(UIJqfk.class);
   List list = new ArrayList();
   Jqfk j;
   Connection conn =
    uiList.service_.getDataSource("WaterDS").getConnection();
   try {

 

    Statement stmt =
     conn.createStatement(
      ResultSet.TYPE_SCROLL_SENSITIVE,
      ResultSet.CONCUR_UPDATABLE);
    String sql =
     "select * from ZLS.JQFK where YHH = '" + yhh + "' ";
    ResultSet rs = stmt.executeQuery(sql);
    while (rs.next()) {
     j = new Jqfk();
     j.setYhh(rs.getString("YHH"));

 

     j.setYhm(rs.getString("YHM"));
     j.setYsl(rs.getString("YSL"));
     j.setZje(rs.getString("ZJE"));
     j.setCbqk(rs.getString("CBQK"));
     j.setJqrq(rs.getDate("JQRQ"));
     j.setHs(rs.getString("HS"));
     j.setHsrq(rs.getDate("HSRQ"));

 

     list.add(j);
    }
    //rs.close();
    //stmt.close();
    //conn.close();
    uiJqfk.setData(list);
    uiList.setRenderedSibling(UIJqfk.class);
   } catch (SQLException e) {
    e.printStackTrace();
   } finally {
    conn.close();
   }
  }
 }

 

注意，这里只要关闭conn就可以了，不要关闭rs和stmt

 

另外，显示的时候一定要用

static private Formater ft_ = Formater.getFormater(null) ;

w.write(ft_.format(y.getYhch()));

来防止数据库该字段有异常
