On http://hibernate.org/others/ , the following links are broken:

• http://docs.jboss.org/hibernate/stable/shards/reference/en/html/
• http://docs.jboss.org/hibernate/stable/shards/reference/en/html_single/
• http://docs.jboss.org/hibernate/stable/shards/reference/en/pdf/hibernate_shard.pdf
• http://docs.jboss.org/hibernate/stable/shards/api/

There symbolic link from hibernate/stable/shards to hibernate/shards/3.0 is probably missing.
