As per Hibernate Core Migration Guide : 3.6,
"# The namespaces for the Hibernate dtd files have changed from
http://hibernate.sourceforge.net/hibern ... on-3.0.dtd to
http://www.hibernate.org/dtd/hibernate- ... on-3.0.dtd "
but there is a bug reported for the NEW DTD location about getting intermitent "org.dom4j.DocumentException: Connection refused Nested exception: Connection refused" errors. Reverting back to the hibernate.sourceforge.net DTD solved all problems it seems.
Could anyone confirm if the new location is still not ready. Is it ok if we continue to use old sourceforge.net DTD reference location in 3.6 hibernate version?
