Hi,


Any ideas why I would sometimes get a "org.dom4j.DocumentException: Connection timed out: connect Nested exception: Connection timed out: connect"
exception (see below)?

And yes, I'm still using 2.0 DTDs with Hibernate 3. The first step of my upgrade roadmap is to run the current setup with HB3 without any modifications.

Thanks
Dmitry

never mind. lol. I've been trying to figure this out for two days, and when I finally gave up and decided to post the question, it came to me a moment after I clicked the submit button: Hibernate3 jar doesn't have the 2.x DTD, so the parser is trying to download from the server.


It would be really nice if the next release of Hibernate would also include the 2.x DTD.

So every application breaks completely and silently instead of forcing people to read the migration guide?

You are not supposed to use the 2.x DTD in 3.0!

I've added an ERROR log to the resolver to finally get rid of this problem...
