If you get MappingException error, there are two things you should check out: Make sure the name of the *.hbm.xml is spelled correctly — not *.hmb.xml nor *.mbh.xml Make sure the Build Action property is set to “Embeded Resource.” I learned this the hard way.

To fix it, we need to edit the /etc/apache2/httpd.conf or /etc/apache2.conf and add the following line: ServerName nameofserver Now, restart the apache server (# apache2ctrl restart) and should no loger see the previous message.
Recently, SVN has been installed on a local Debian box at work. This could have been done a bit earlier in my opinion, but well it’s better be a little late than never.
