I am seeing this error:

org.dom4j.DocumentException: Connection timed out: connect Nested exception: Connection timed out: connect

The DOCTYPE declaration is correct:

<!DOCTYPE hibernate-mapping PUBLIC "-//Hibernate/Hibernate Mapping DTD 3.0//EN" "http://hibernate.sourceforge.net/hibernate-mapping-3.0.dtd">

I can browse to the DTD url, and the hibernate jar has the DTD in it and Dom4J should use the hibernate entity resolver and pull the local dtd, correct?

So I'm at a loss. AFAIK, I haven't changed anything - but I must have, it just stopped working.

Much thanks for your assistance, been looking at this for a full day now.

My co-worker discovered that adding this to the host file resolves this:

192.168.1.155 hibernate.sourceforge.net

For some reason with how we are loading our xml resources, the local dtd resolver isn't working. If you are in a similar situation, give this host file addition a shot (even if you are able to already browse to the DTD in a browser).
