Login Servlet?
Does anyone know where I could find code for a login servlet using JDBC.
I have a login tested, it checks the database and it outputs whether the
username and password are correct to the jsp page, but I need to use a
servlet for redirecting the user.
Here is the code i have for the login procedure
public void applyChanges() throws Exception
{
Statement statement = connection.createStatement();
try{
ResultSet rs = statement.executeQuery("SELECT * from
Registration
WHERE (Username ='"
+ theUsername
+ "' AND Password = '"
+ thePassword + "');");
boolean found = rs.next();
System.out.println(found);
rs.close();
statement.close();
if(found == true)
{
System.out.println("THAT IS THE CORRECT
USERNAME AN PASSWORD!!");
//request.setAttribute ("servletName",
"servletToJsp");
rs.close();
statement.close();
//response.sendRedirect ("/login.jsp");
}
else
{
System.out.println("YOU ARE NOT IN OUR DB
:-(");
rs.close();
statement.close();
}
}
catch (Exception e)
{
}
}
}
ANY help at all would be much appreciated. Thanks in advance, Mick

Login Handler Question
Hi all
Does anyone know where I could find code that when after a user has given a
correct username and password on the login.jsp page, a loginHandler bean
will redirect the user to a new page, and if the user gives a username and
an incorrect password, the login page will appear again.
I have the bean checking the DB and validating the username and password
with the following code:
public void loginHandler() throws Exception
{
Statement statement = connection.createStatement();
try{
ResultSet rs = statement.executeQuery("SELECT * FROM
Registration WHERE (Username ='"
+ theUsername
+ "' AND Password = '"
+ thePassword + "');");
boolean found = rs.next();
System.out.println(found);
if(found == true)
{
System.out.println("THAT IS THE CORRECT
USERNAME AN PASSWORD!!");
}
else
{
System.out.println("YOU ARE NOT IN OUR DB
:-(");
}
}
catch (Exception e)
{
}
}
}
Any help would be much appreciated,
Thanks in advance, Mick

Question on import javax.servlet.*;???
Hi Does anyone know why I get the following error when I try to import "import javax.servlet.*; AND import javax.servlet.http.*;" I need them for my loginHandler to use sendRedirect etc. This is the error: C:\JBuilder35\jdk1.2.2\binjavac c:\tomcat\webapps\projectuser\web-inf\classes\l oginHandler.java c:\tomcat\webapps\projectuser\web-inf\classes\loginHandler.java:7: Package java. servlet not found in import. import java.servlet.*; ^ c:\tomcat\webapps\projectuser\web-inf\classes\loginHandler.java:8: Package java. servlet.http not found in import. import java.servlet.http.*; Anyone have any ideas?

Re: Question on import javax.servlet.*;???
Nice one (Again) for the reply Craig, The problem is the code I sent was just me messing around seeing what would happen if I took out the 'x', but I forgot to put it back in when I was copying the code. Here it is again: SOURCE: package login; import java.util.*; import java.sql.*; import java.io.*; import java.lang.*; import javax.servlet.* import javax.servlet.http.*, ERROR: c:\tomcat\webapps\projectUser\web-inf\classes\loginHandler.java:8: Package javax .servlet not found in import. import javax.servlet.*; ^ c:\tomcat\webapps\projectUser\web-inf\classes\loginHandler.java:9: Package javax .servlet.http not found in import. import javax.servlet.http.*; ^ 2 errors Therefore I assume the problem is to do with the classpath. The file 'servlet.jar' is located in my c:\tomcat\lib folder and also in c:\tomcat\lib\common folder I also have the folder 'tomcat-servletapi-3.2' in the root directory of my c drive. Might the problem have something to do with this? I know Ive been at this for bout 6 months now, but what do you mean when you say "'servlet.jar' should be located in the classpath"? I compile my files using DOS and the javac command. My JDK is located in c:\Jbuilder35\jdk1.2.2\bin I do not use JBuilder to write my beans, I use homesite, an HTML editor that also allows .java files. Do I have to move the server.jar file somewhere into the JDK folder or something? As you can probably tell Im kinda clueless, even still my projects nearly there, if I can just sort out this login stuff. Yopur help is much appreciated.

Help on error?
Hi all
Does anyone know why the following code causes my Java (tomcat ) window to
crash. Any help at all would be much appreciated
public String getName() throws Exception {
Statement statement = connection.createStatement();
int myInt = 1;
ResultSet rs = statement.executeQuery("SELECT Name"+
" FROM nameAddress" +
" WHERE ID = ("+
myInt + ")");
rs.next();
String myString = rs.getString("Name");
//change the resultSet to a string
//so it can be used by the jsp page
return myString;
}
I think the throws exception part is causing the server to crash.
However on the JSP page i have the following line of code
% nameAddresshandler na = new nameAddresshandler(); %
%System.out.println(na.getName());%
This prints out the correct name of the "Name" to the tomcat window, then a
java error appears and shuts down tomcat. Do I have to install JDK again?
Thanks in advance, Mick

RE: Help on error?
Thats a good guess alright. Im using the JDBC-ODBC bridge with an MS Access
database :-(
I have to do it that way coz a fella whos in my course set up the Drivers
and all that for me.
Could you just tell me how I would close the Result set and statement.
Is it 'rs.close();' or something along those lines.
Thanks again in advance,

What database and JDBC driver are you using? If I had to guess I'd
say that you are using the JDBC-ODBC bridge and you have encountered one of
several problems that JDBC-ODBC bridge has. There is no fix, only
workarounds. In your case the problem is because you haven't closed the
ResultSet and Statement, leaving them open so that the next query executed
will cause an error. This is part of the reason that the bridge is labeled
experimental and is not supported by Sun.

Simple SQL Statement.....
Hi,
Does anyone know why this statement WILL ADD a value to a record (Price)in a
database named parkingPrice:
Statement statement = connection.createStatement();
String query = "INSERT INTO parkingPrice(" +
" Price " +
") VALUES ('" +
thePrice +
"')";
System.out.println("query "+ query);
statement.executeQuery( query );
but this statement WILL NOT UPDATE the record Price:
Statement statement = connection.createStatement();
String query = "UPDATE parkingPrice SET Price = thePrice";
System.out.println("query "+ query);
statement.executeUpdate( query );
The Variable thePrice is got using this function
public void setPrice( String price ) {
thePrice = price;
}
It works for INSERT but not UPDATE
Also my table has only 1 value , being Price(1 row and 1 column).
I do not want to INSERT, I just want to UPDATE the single value.
Anyone at all with any ideas???
Thanks in advance, Mick

SIMPLE SQL QUERY.....
Hi
Can anyone help me with a simple SQL update query.
When I insert a value into my DB using the INSERT INTO statement I have no
problem.
Statement statement = connection.createStatement();
String query = "INSERT INTO parkingPrice (" +
" price " +
") VALUES ('" +
thePrice +
"')";
statement.executeQuery( query );
However I dont want multiple rows so when I try and do an update instead
using the following:
String query = "UPDATE parkingPrice SET " +
"Price='" + thePrice + "'";
System.out.println("query "+ query);
statement.executeUpdate( query );
There is no affect on the DB. I get no SQL errors and in the tomcat window
using the line "System.out.println("query "+ query);"
The query UPDATE parkingPrice SET Price='5'
The query seems valid yet there is no affect on the DB.
I am using MS ACCESS. Is the problem in the way the DB is set up?

Re: SIMPLE SQL QUERY.....
Hi Clayton,
Thanks for the help, but there is still a new row added into the table
"parkingPrice". This is what my applyChanges methos looks like now
public void applyChanges() throws Exception
{
Statement statement = connection.createStatement();
String query = "INSERT INTO parkingPrice (" +
" price " +
") VALUES ('" +
thePrice +
"')";
//String query = "UPDATE parkingPrice SET " +
//"Price= thePrice ;
System.out.println("query "+ query);
//statement.executeUpdate( query );
//statement.executeQuery( query );
int rows = statement.executeUpdate( query );
}
}
The variable thePrice is taken from a jsp page and the function just takes
the value "price" and assigns it to thePrice;
public void setPrice( String price ) {
thePrice = price;
}
Any ideas,
Thanks in advance, Mick

For your insert, replace
statement.executeQuery( query );
with
int rows = statement.executeUpdate( query );
It has nothing to do with result sets. An "update" can consist of INSERT,
UPDATE, DELETE, and will return the number of rows affected by the SQL
statement. The only time you need to worry about result sets is when doing
a SELECT, and then the executeQuery method would be appropriate.
With regards to the UPDATE not affecting the DB, are you closing the
statement, and the connection? Are you in "autocommit" mode?
Hope this helps,
Clayton

You have to either make the method a static one,

Whats the Story with Static Referencing???
Please please help coz my p
EASY TO SOLVE ERROR PLEASE??????
Hi all Im pretty new to JSP but I have got tomcat and a couple of JSP pages and beans working. The site I am designing for my project contains 2 frames, the left hand frame contains the links and the right hand frame contains the targets. On the left I have a 2 links, the first called 'set availability' and the second 'view availability'. On my right hand frame in the 'set availability' page when I set the availability and click submit, a response page is brought up at the bottom of the 'set availability' pageas follows: "YOU SET AVAILABILITY AS BEING 15" (or whatever the user set it at) My problem is that when I click 'view availability' and try to bring up the variable that has been set in the set availability page. An error as follows comes up "Tried to do an operation on a null object." Does this have to do with scope="session" scope="request" or scope="page" I think the problem is that the bean is only set while the set Availability page is loaded because if I got to another page and then back to the setAvailability page the response at the bottom of the page is gone Anyone got any ideas at all, Id say its a fairly easy problem to solve? Big Thanks in advance, Michael _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]

Cache in tomcat....?????
Hi, I got my first JSP pages and bean working a few minutes ago. Basically what the application does is take input from the first page and output it on a response page after submission. My problem is that when I tried to modify the response page it keeps using the old version. I actually deleted the response page, yet still the response page loads after submission??

Error: 500 -- Please Help ..............
Hi all. Help needed here for an amatuer, should be easy enough to fix.
Im working on an online car park booking system for a project for uni.
Here is my problem.
I have a frames page, index.html, for the booking system in
webapps\Admin.
One of the pages within the frames page is called view_parking_cost.jsp.
Within view_parking_cost.jsp, I have the following JSP code declared at the top.
%@ page import="parkingPrice.ParkingPriceHandler" %
jsp:useBean id="parkingpricebean" scope="page" class="parkingPrice.ParkingPriceHandler" /jsp:setProperty name="parkingpricebean" property="*" /
<%@ page import="parkingPrice.ParkingPriceHandler" %>
In the webapps\Admin\Web-inf\Classes\parkingPrice folder I have written the following .java file and compiled it to .class using JDK.
Name of file = "ParkingPriceHandler.java"
package parkingPrice;
public class ParkingPriceHandler{
private String thePrice;
public ParkingPriceHandler() {
thePrice = null;
}
public void setPrice( String Price ) {
thePrice = Price;
}
public String getPrice() {
return thePrice;
}
}
In the Server.xml file I have added this code for the context.
docBase="webapps/Admin"
debug="0"
reloadable="true"
trusted="false"
When I start the server and point my webbrowser to
http://localhost:8080/Admin/index.html
and then go to the set_parking_price.jsp page I get the following error:
Error: 500
Location: /Admin/set_parking_cost.jspInternal Servlet Error:org.apache.jasper.JasperException: Cannot find any information on property 'Price' in a bean of type 'parkingPrice.ParkingPriceHandler'

CLASSPATH?
Hi I saw the question below in FAQ section of the tomcat web page What I want to know is how you set your classpath and hwere is it? Thanks, Mick Q: What do I need in my CLASSPATH? A: All you need is a correct version of JDK (1.1.x or 1.2). Since the JSP engine also uses 'javac' it needs to be in the CLASSPATH. If you are using JDK 1.1.x it will automatically be included. If you are using JDK 1.2 you will need to set JAVA_HOME to the directory where JDK is installed or alternately you can put "tools.jar" in your CLASSPATH. All other classes, jar files that are needed, are put by the startserver script and you don't need to worry about them _ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]

FIRST JSP PRGRAM - PLEASE HELP!
Hi I need help!! I think this problem will be easy to solveas this is my first attempt at a JSP application. I am copying a JSP program from the java.sun.com website and attempting to run it on tomcat. The program is a simple one, the user enters his name into a text box and presses submit. His name is then printed up on the screen, i.e. "Hello name". I have created the two .jsp files (hellouser.jsp and response.jsp) and stored them in C:\jakarta-tomcat\webapps\Hello\ I have created the bean (namehandler.java) as a .java file and stored it in C:\jakarta-tomcat\webapps\Hello\Web-inf\Classes\ Are these the right folders to store those files in? I have tried compiling the .java file to a .class in JBuilder, but I keep getting the following warning: "Warning #908: check sourcepath; source c:\jakarta-tomcatzwebapps\Hello\Web-inf\Classes\namehandler.java cannot be found on source pathby appending \hello\namehandler.java to each sourcepath entry." ( hello is the name of the package) I think the problem may be because I cant generate the .class file. Anyone know why this might be? When I try to view the Application while tomcat is running I get this error message: Error: 500 Location: /Hello/hellouser.jspInternal Servlet Error:org.apache.jasper.JasperException: Bad file argument to include at org.apache.jasper.compiler.JspParseEventListener.handleDirective(JspParseEventListener.java, Compiled Code) at org.apache.jasper.compiler.DelegatingListener.handleDirective(DelegatingListener.java:116) at org.apache.jasper.compiler.Parser$Directive.accept(Parser.java, Compiled Code) at org.apache.jasper.compiler.Parser.parse(Parser.java, Compiled Code) at org.apache.jasper.compiler.Parser.parse(Parser.java:1038) at org.apache.jasper.compiler.Parser.parse(Parser.java:1034) at org.apache.jasper.compiler.Compiler.compile(Compiler.java, Compiled Code) at org.apache.jasper.runtime.JspServlet.loadJSP(JspServlet.java:413) at org.apache.jasper.runtime.JspServlet$JspServletWrapper.loadIfNecessary(JspServlet.java:149) at org.apache.jasper.runtime.JspServlet$JspServletWrapper.service(JspServlet.java:161) at org.apache.jasper.runtime.JspServlet.serviceJspFile(JspServlet.java:261) at org.apache.jasper.runtime.JspServlet.service(JspServlet.java, Compiled Code) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.tomcat.core.ServletWrapper.handleRequest(ServletWrapper.java, Compiled Code) at org.apache.tomcat.core.ContextManager.service(ContextManager.java:559) at org.apache.tomcat.service.http.HttpConnectionHandler.processConnection(HttpConnectionHandler.java:160) at org.apache.tomcat.service.TcpConnectionThread.run(SimpleTcpEndpoint.java:338) at java.lang.Thread.run(Thread.java:479)If anyone has any idea at all where the problem may lie please, please help me.Thanks in advance, Mick Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, email: [EMAIL PROTECTED]
