MySQL Forums :: MySQL Administrator :: remote access to mysql database

I'm trying to set up a development environment on a windows XP machine where I can do Java development on the local machine using Eclipse, a local instance of a Tomcat server but access the MySQL database through the web. I've checked my GRANT tables and think they are set up correctly to allow remote access. Here's the result of a Show Grant for my username:

GRANT SELECT ON *.* TO 'username'@'%' IDENTIFIED BY PASSWORD 'encrypted password'

I can access the database (select statement) with no problem from the host on which the MySQL database is running. I take the same script (PHP in this case) and try it from another server and it takes forever and then doesn't return anything. From Java I get a ConnectException: Connection timed out exception. (Actually it's a com.mysql.jdbc.CommunicationsException) but ultimately I think it is due to a time-out.

Any ideas what I'm doing wrong???

Thanks,

Jim
