I have a stand alone application that it's launched every night, randomly some days appear an error when it's launched. The error it's like when i have a the network down.
In the night this script it's launched 4 times in sequence and only the first excecution have this error... the other 3 are ok!...
A name resolution problem of hibernate.sourceforge.net the first execution?

Ideas?

Thanks!

Matteo

a network connection is not required for reading configuration files. The dtds are available in the hibernate jar file. It may be required if your mapping files have a different dtd specified than the one available in the jar file.

I had this connection problem when I upgraded to Hibernate 3 from Hibernate 2. The mapping files were using the hibernate 2 dtd. So while loading the configuration hibernate was going to the internet.
