WHat I'm sure is a simple problem but not for me...

Question

Greetings all,
I am putting together a simple applet that accesses a MYSQL database, reads all the records out and writes them to the "graphic" screen via the paint method.
Everything works fine when I run the applet in a player (Eclipse) but when I move everything over to the web server, the html page (static part) displays but the applet fails with an error. The Java Console tells me the following:
java.lang.NoClassDefFoundError: jdbctest01$Database
     at jdbctest01.init(jdbctest01.java:41)
     at sun.applet.AppletPanel.run(Unknown Source)
     at java.lang.Thread.run(Unknown Source)
The applet code it is referencing is:
40 ...
41 db = new Database(url, user, pass);
42 ...
and the "Database" method being invoked is:
public class Database {
public Database(String url, String user, String pass){
     try{
connection = DriverManager.getConnection(url, user, pass);
     catch(SQLException e) {
As I said, nothing to it...but I can't figure out why its not working (but I am sure its obvious). I have tried it on IE & Firefox; same result. Both have java enabled, the class file and the html files all have open permissions (machine is not on the net) so I doubt anything as simple as security is at work. I have been staring at this for a while and I am losing feeling to my lower extremities. I hope someone out there can offer some ideas as to what I should be checking for or what else to do diagnostic wise.
Many thanks,
Pete

Axel,
Many thanks for the lead (Incidentally, it's not my code; they use it for "education" (of who I'm not sure) and they just discovered there are no compiled copies anywhere so, no examples, screen shots etc.). I "volunteered" to try and get it working and...
Anyway, I added the jdbctest01$Database.class and I got "different" results. Now, it gets into the database class and when it executes the connection = DriverManager.getConnection(url, user, pass); it returns a SQLException error. I have confirmed that the url, user and pass values ARE correct so I am not sure where this error is coming from. The "connection" value is typed Connection. There really isn't anything else that I can see could be wrong. One other thing; the exception is caught in the Database instance but it still manages to return to the statement following the invocation of the Database class. The connection value it returns looks like it might be right (the returned value is: jdbctest01$Database@adb1d4 which I think is "like" it should be but no luck). The first statement on return is: stmt = connection.createStatement(ResultSet.TYPE_SCROLL_INSENSITIVE, ResultSet.CONCUR_READ_ONLY); and stmt is typed Statement) And at this point,it dies with a null pointer error.
Any other ideas will be greatly appreciated.
Thanks,
Pete
