Hi. I create simple Hibernate application using Swing. It works perfectly. But only when I use database(MYSQL) into my local host. When I try to use database into our network it fails without any exception. Program just stopp when try to connect. I try to connect using MySQL Gui Tools - all perfect, I could even connect through NetBeans IDE, all is perfect. Why it can't connect - I don't know. Thank in advance for Your help.

have you already tried to enable debug mode (log4j.logger.org.hibernate=debug)? what is tracing when the application stops?

Here stop and the end of story :)

I think you would track you connection in order to know what is happing behind...i guess you are experiencing a connection problem with you database when you want connect from a remote machine.

to trace JDBC driver activity, try P6Spy (http://www.p6spy.com) or place this code before start Hibernate

Now have error
