I have decided to go with Apache and Tomcat for my Railo server, and so today rebulit the server from scratch. The server is still running Ubuntu 9.10 and I did a LAMP install.
Next I used Viviotech Railo installer - thanks Jordan. This installs Tomcat and Railo and then hooks it up to Apache (using mod_jk). Thanks also to the great people on the Railo list for helping me with Apache and Tomcat configurations for rewrite rules and Aliases.
For the records
