我为一个查询使用了一个结果集变量，它运行正常。但是当我尝试在同一个.jsp页面中为其他查询声明更多Resultset变量时，我得到了“Resultset not resolved type”错误。
org.apache.jasper.JasperException: Unable to compile class for JSP:
An error occurred at line: [53] in the jsp file: [/frozen.jsp]
Resultset cannot be resolved to a type
50: }
51: avg=avg/n;
52:
53: Resultset rs2 = stmt2.executeQuery("select amarate from amarating where movie_id='frozen'");
54: Resultset rs3 = stmt3.executeQuery("select dor,length,genre from moviedetails where movie_id='frozen'");
55: String ama = rs2.getString("amarate");
56: String dor = rs3.getString("dor");
