I'm back to square one again. I had mysql running and working great last night. Now whenever I try to run my program I get an error message: java.sql.SQLException: Communication link failure: java.io.IOException, underlying cause: Unexpected end of input stream Do I have something set up wrong? Could this be caused from the firewall protection that keeps popping up?
Did you leave the connection open all night? MySQL can be configured to drop connections that have been idle for a defined period of time. I believe the default time is 8 hours of inactivity (connections that are idle for 8 hours get dropped). Try reconnecting to the database to see if that fixes your problem. It test this condition in your code, you could run the .isClosed() method on your Connection object. David

I tried the .isClosed() but got the same error. I think mysql has has been connected since I got it started on Saturday. Every day when I try it even before I start mysql I get the same error. I think if mysql was disconnected I would be getting the other error that I was getting before Saturday. I have closed it using the X button and have looked for ways to shut it down to start over but haven't found anything.
