Class.forName(DBDRIVER).newInstance();
conn=DriverManager.getConnection(DBURL,DBUSER,DBPASS);
String sql="SELECT empno,ename,job,sal,hiredate FROM emp";
Statement stmt=con.createStatement();
rs=stmt.executeQuery(sql);dong_y888 2013-02-04

改为下面的
conn=DriverManager.getConnection(DBURL,DBUSER,DBPASS);
