String sid = (String)session.getAttribute("id");
String cno="",cname="";

int pscore=0,qscore=0,grade=0;
double credit=0.0,kpoint=0.0;

你的成绩为：















<%
student st=new student();
ResultSet rs1=st.getSname(sid);
ResultSet rs = a.getScoreone(sid);
String smajor=rs1.getString("smajor");
System.out.println("smajor====="+smajor);
while(rs.next()){
cno=rs.getString("cid");
cname=rs.getString("cname");
credit=rs.getDouble("credit");
pscore=rs.getInt("pscore");
qscore=rs.getInt("qscore");
grade=rs.getInt("grade");
kpoint=rs.getDouble("jpa");

System.out.println("cno"+"cname"+"credit");
%>









课程号课程名学分平时成绩期末成绩成绩学分积点查看排名
<%=cno%><%=cname%><%=credit%><%=pscore%><%=qscore%><%=grade%><%=kpoint%>返回

说明你的jsp中有编译错误，检查下你的jsp文件，一般ide会把语法错误的地方加上高亮的。

把你的完整代码传到网盘，这样才能帮你分析.

<%@page import="bean.student;"%>把最后的分号去掉试试
