Hello,
I am using Hibernate in an SWT application that connects to an Oracle 11g database
The database exists on the same machine that hosts the application
When i run the jar the application starts and connects successfully to the database
BUT
When I unplug the cable from the machine, a problem happens,
Hibernate can't connect to the database (Although it exists on localhost)
and the console stops much time on this line
INFO: connection properties: {user=off_reserve, password=****}
and finally an exception is raised
WARNING: Could not obtain connection metadata

Could anyone provide me with a solution for this problem ??

Thanks

Did you use 127.0.0.1 or localhost in your config or did you use the "remote" IP?
