Deny svn metadata in apache
When your webfolder is under revision control you have those ".svn" meta-data folders inside. These could be a possible security risk because a user could request a file that is not processed by php or tomcat (the file has not the ".php" ending) and maybe gather information about database passwords or something like that. To tell apache to deny the paths "*/.svn/*" you can use the following rewrite rule ... just add it to your httpd.conf and restart apache:
RewriteEngine on
RewriteCond %{REQUEST_URI} /\.svn [NC]
RewriteRule / - [F]
... be sure that you have loaded mod_rewrite in your configuration ...
