jsp出现错误-->水影月圆转移 - 编程论坛

使用bean的jsp出现错误java代码：
package vote;
import java.sql.*;
public class vote_conn{
String sdbdriver="sun.jdbc.odbc.JdbcOdbcDriver";
String sconnstr="jdbc:odbc:vote";
Connection connect=null;
ResultSet rs=null;
public vote_conn(){

try{
Class.forName(sdbdriver);

}catch(java.lang.ClassNotFoundException e){System.err.println(e.getMessage());
}
}
public ResultSet executeQuery(String sql){
try{
connect=DriverManager.getConnection(sconnstr,"","");
Statement stmt=connect.createStatement();
rs=stmt.executeQuery(sql);
}catch(SQLException ex){System.err.println(ex.getMessage());
}
return rs;
}

public int executeUpdate(String sql){
int result=0;
try{
connect=DriverManager.getConnection(sconnstr);
Statement stmt=connect.createStatement();
result=stmt.executeUpdate(sql);

}catch(SQLException ex){System.err.println(ex.getMessage());
}
return result;

} }
jsp代码：
<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>

请大家帮我看看啊
谢谢了！

我的配置是tomcat5.5.17 +j dk1.5

为什么我网上下的每个代码都出现while的问题
org.apache.jasper.JasperException: Exception in JSP: /index.jsp:65

62: </tr>
63: <%
64: String sql="select * from 论坛";
65: ResultSet rs=odbc.executeQuery(sql);
66: while(rs.next()){
67: %>
68: <tr bgcolor="#D1EBF1">

为什么啊
