weblogic-ejb-jar.xml文件描述如下：
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE weblogic-ejb-jar PUBLIC "-//BEA Systems, Inc.//DTD WebLogic 8.1.0 EJB//EN" "http://www.bea.com/servers/wls810/dtd/weblogic-ejb-jar.dtd">

这些配置我都写了为什么还有名字没有找到的异常呢？
请大家帮忙看看。谢谢！ QQ：86322591。MSN：rodney_luo@163.com

解决办法是看了代码：ResultSet rs = ps.getResultSet();
之前一个要先执行ps.executeQuery();这样就不会有错了。

IF NOT IsNull(ld_from_date) AND IsNull(ld_date) THEN
 ls_sql_where = ls_sql_where + &
 " Trunc(~"CITYNET_INTERFACE~".~"REQUESTED_PICKUP_DTM~") >= TO_DATE('" + &
 String(ld_from_date, 'dd/mm/yyyy') + "', 'dd/mm/yyyy')" + " AND "
 ls_query_criteria = ls_query_criteria + " Trip Date >= " + String(ld_from_date,'DD/MM/YYYY')
END IF

IF IsNull(ld_from_date) AND NOT IsNull(ld_date) THEN
 ls_sql_where = ls_sql_where + &
 " Trunc(~"CITYNET_INTERFACE~".~"REQUESTED_PICKUP_DTM~") <= TO_DATE('" + &
 String(ld_date, 'dd/mm/yyyy') + "', 'dd/mm/yyyy')" + " AND "
 ls_query_criteria = ls_query_criteria + " Trip Date <= " + String(ld_date,'DD/MM/YYYY')
END IF
把上面的代码用SQL的查询语句来实行。
这时我用到了一个between运算符，这个运算符会包括它后的两个入参：
如：select table.A from table where table.A between 5 and 10.也就是说这时的条件A>=5 and A<= 10的记录。

  thisObj.form.drv_nm.value = "";
  v = trim(thisObj.value);
  if (v + "A" == "A") {
    _CLICKCHECK = true;
    _ckNric = true;
  } else {
    thisObj.value = v.toUpperCase();
    _CLICKCHECK = false;
    _ckNric = false;
  }
}
