这一段的finally少了结束的"}". --------------------编程问答-------------------- 少写了一个}号。 --------------------编程问答-------------------- 同意楼上， --------------------编程问答-------------------- 怎么我看是没有定义rs对象，
插入操作也不用ResultSet，既然没有定义更不用提关闭了，所以出错呗
try{
rs.close() ; 《-----------------this，删
pstmt.close() ;
conn.close() ;
}catch(Exception e){} --------------------编程问答-------------------- 你都没有定义ResultSet 你关闭当然报错了！！！ --------------------编程问答-------------------- rs在哪里定义的而且提示说的是少了"}" 检查下吧 --------------------编程问答-------------------- 同意三楼…… --------------------编程问答-------------------- 是JSP的语法错误啊 --------------------编程问答-------------------- 各种……
