You should use the statement object instead of connection object to call the
method executeQuery
Statement stmt = connection.createStatement();
stmt.executeQuery(sql);

Subject: ResultSet not found
I'm using a JavaBean to communicate with a mysql database.
Here's what I do:
1. login.jsp -- user enters ID and password; also when this page is
loaded the ConnectionBean is declared with scope="session"
2. when the user hits "submit", the form sends the data to checklogin.jsp
where the submitted data is checked against the database.
I'm getting an error though at checklogin.jsp

Here is the code I have in checklogin.jsp
*
jsp:directive.page import="java.sql.*,java.sql.ResultSet"
errorPage="error.jsp" /
jsp:useBean id="connection" class="ConnectionBean" scope="session" /
%
String p_ID = request.getParameter("player_id");
String p_passwd = request.getParameter("player_passwd");
connection.setAutoCommit(false);
String sql;
sql = "SELECT player_id, player_passwd FROM player WHERE player_id=" + p_ID
+ " AND player_passwd=" + p_passwd;
ResultSet results = connection.executeQuery(sql);
if( results.next() ) { %
% /* ID and password correct, forward to main page */ %
jsp:forward page="index.jsp" /
% } else { %
% /* ID and password incorrect, forward to login.jsp to reenter login
info */ %
jsp:forward page="login.jsp" /
% } %
**
Is there an obvious(or not so obvious) reason why the jsp can't find the
ResultSet class?
Thanks,
Luoi
btw. I'm using Tomcat 3.2.1/linux/apache
my jsp's are located in /home/httpd/html/gamezone rather than
$TOMCAT_HOME/webapps/
