So I'm busy with a small website I'm able to login at the website with the help of sessions that all goes well.
But I'd like to expand the website a bit more, it's a sport website where people can add players, add teams, and add matches, and those are stored on a MySQL DB.

The thing where it goes wrong is when I'm trying to store a player to the Database.
Here is the java class:

package oeffenen;

import java.sql.ResultSet;
import database.DatabaseConnection;
import java.sql.SQLException;

public class Speler {

    oeffenen.Connection connection;
    DatabaseConnection dbc;
    boolean verbinding = false;
    String spelerCode = "";
    String spelerNaam = "";
    String spelerAdres = "";
    String spelerPostcode = "";
    String spelerTelefoon = "";
    String spelerGeboortedatum = "";

    public Speler() {
    }

    public Speler(String spelerCode) {
        this.connection = new Connection("oeffenen", "root", "");
        int con = connection.openConnection();

        if (con == 0) {

            verbinding = true;
            this.dbc = connection.getConnection();

            String selectQuery = "select spelerNaam, spelerAdres, spelerPostcode, spelerTelefoon, spelerGeboortedatum from speler where spelerCode = '";
            ResultSet rs;

            selectQuery += (spelerCode + "'");
            if (dbc.sendQuery(selectQuery) == -1) {
                return;
            }
            this.spelerCode = spelerCode;
            rs = dbc.getResultSet();
            try {
                rs.first();
                this.spelerNaam = rs.getString("spelerNaam");
                this.spelerAdres = rs.getString("spelerAdres");

            } catch (SQLException se) {

This has been keeping me busy for some weeks.

You should have posted exact error message. You cannot expect people to try and debug your code without knowing exact DB structure...

You should have posted exact error message. You cannot expect people to try and debug your code without knowing exact DB structure...

Ya I kind of figured that out.
But I'm not really getting any error message.
Here is the error I get:

http://imageshack.us/photo/my-images/151/errormsg.png/

It says that there is a detailed error message in the log, but I don't know the log location....

Here is my DB structure:

drop database if exists oeffenen;
create database oeffenen;
use oeffenen;

create table account (
        username varchar(40) ,
        wachtwoord varchar(32) ,
	primary key(username)
) engine = innodb;

create table speler (
        spelerCode varchar(40) ,
        spelerNaam varchar(40) ,
        spelerAdres varchar(40) ,
        spelerPostcode varchar(40) ,
        spelerTelefoon varchar(40) ,
        spelerGeboortedatum varchar(40) ,
        primary key(spelerCode)
) engine = innodb;

insert into account(username,wachtwoord)
            Values('matt','super');

insert into speler(spelerCode,spelerNaam,spelerAdres,spelerPostcode,spelerTelefoon,spelerGeboortedatum)
            Values('453464','Testing','Test Adres 2','3674 TE','06347969357','12-12-2009');

Thanks for the reply.

YOUR_TOMCAT_INSTALLATION_DIRECTORY/logs and check catalina.out

YOUR_TOMCAT_INSTALLATION_DIRECTORY/logs and check catalina.out

Hmm I'm using Netbeans in combination with Xampp.
My "C:\xampp\tomcat\logs" folder is empty.
There is a "catalina_start.bat" file in the root folder of Tomcat, but when I try to run that, it give me some errors:

Error: The system was unable to find the specified registry key or value.

XAMPP: Cannot find the current JDK of the installation!

XAMPP: Cannot set JAVA_HOME. Aborting...

Or maybe I'm just looking at the wrong place.

I also checked: "C:\Program Files (x86)\Apache Software Foundation\Apache Tomcat 6.0.26\logs" Also empty.

And "C:\xampp\apache\logs" Does contain log files.
"access.log" < Empty.
"ssl_request.log" < Empty.
"error.log" < Contains logs, but nothing useful.

1) Make sure that you set JAVA_HOME as your environment variable (there is a description how to do it in this post)
2) This may sound harsh but either you need to read XAMPP documentation to find where the things are or just delete XAMPP and use simple installation of Tomcat and your chosen database so you can follow advice given.

Personally I see no need for XAMPP that was predominantly developed for lazy PHP developers that weren't willing to learn how to set up Apache 2 with PHP and MySQL

2. It's not harsh at all, I'm just happy someone is at least helping me!
And XAMPP is just a temp solution, soon it will be gone.
But for now I will keep using it(But it will be gone within a month.)

Hope the log gave you enough information, I just got this all to work around 5:30 am so couldn't check the log myself(To sleepy).

1. Line 2 is showing that you have double declaration for Java (not a big issue but you should clean it out)
2. Line 47 is saying that you have something already running on port 8080 you should check that Windows is not running Tomcat as service be default on pc start up

2. Line 47 is saying that you have something already running on port 8080 you should check that Windows is not running Tomcat as service be default on pc start up

1. The double declaration is a weird thing, because the java path was only 1 time in my System variable: Path. So I removed that one.

2. I changed the ports to 8081 instead, hope that doesn't matter.
Here is the new log:

;) you need to run your application get that error in the logs. What you did is just starting and stopping server. So there is nothing in the logs

Uhm I have been running the application.
This is how I do it:
First I start catalina_start.bat
Then I start Netbeans, run the website, go to the part that gives me the NULL pointer and get the NULL pointer.
After that I use: catalina_stop.bat
