Jdbc: connection timed out issue

Question

Hi,
I've done some searching, and trying different things, but haven't been able to resolve my problem.
I'm trying to connect a java application to a mysql database on a machine running ubuntu server. The machine the java app is written and run on is ubuntu desktop.
Here is the relevant java code:
String url="jdbc:mysql://jasonServer/phototestdb"; Connection con = DriverManager.getConnection(url, p);
('p' is a Properties object containing user and pw).
I get this error:
com.mysql.jdbc.CommunicationsException: Communications link failure due to underlying exception: ** BEGIN NESTED EXCEPTION ** java.net.SocketException MESSAGE: java.net.ConnectException: Connection refused STACKTRACE: java.net.SocketException: java.net.ConnectException: Connection refused // bunch of stack trace stuff...
I've tried a couple ways of connecting in the url,
String url="jdbc:mysql://jasonServer/phototestdb"; String url="jdbc:mysql://jasonServer:3306/phototestdb"; String url="jdbc:mysql://99.999.9.99/phototestdb"; (9's are my ip address, I have static ip's on wireless network) String url="jdbc:mysql://99.999.9.99:3306/phototestdb";
when I have the ip in the url, it fails immediately and gives me a connection refused error:
establishing connection com.mysql.jdbc.CommunicationsException: Communications link failure due to underlying exception: ** BEGIN NESTED EXCEPTION ** java.net.SocketException MESSAGE: java.net.ConnectException: Connection refused STACKTRACE: java.net.SocketException: java.net.ConnectException: Connection refuse
But when I have the server name in the url, it hangs for a long time and then gives me the timeout error.
Couple other relevant notes;
I am able to ping the server from the desktop using the server name, i.e,
ping jasonServer
but not using the ip addres
I am not able to telnet in the terminal window, I type
telnet jasonServer 3306,
it says "Trying (ip address)
and it just hangs there.
This leads me to believe this isn't really a java issue (and after all that typing I'm probably on the wrong forum)
but something to do with my network.
Any ideas?

solved,
I had to enter this in the server:
(found this on the mysql forum)
You simply need to do:
mysql> GRANT SELECT,INSERT,UPDATE,DELETE,CREATE,DROP
-> ON <dbname>.*
-> TO <username>@<host name>
-> IDENTIFIED BY '<password>';
where <dbname> is the name of the database you are tyring to connect to, <username> is the username of the user trying to connect to the database, <host name> the name of the host (in your case the XXX host) and <password> the password of the user.
