The switchover
I finished the switchover. In addition to moving VPS, I moved off of Resin and onto Tomcat. After dealing with some stuff in Tomcat, I wonder if Resin isn't better suited. Tomcat is really fussy/picky sometimes. More so on Windows than Linux. However, this whole ordeal was a great learning experience.
When I installed on CentOS, I just did a basic 'yum install tomcat5*' and it installed everything. This is where I ran into problems. Nothing was working correctly. I made a decision to get rid of it ('yum remove tomcat5*') and set it up manually myself.
The key thing to remember with tomcat, once you have it up and running is that you're going to want to make a environmental setting file called 'setenv.sh' - The {tomcat install dir}/bin/catalina.sh automatically looks for this file in the same directory. This 'setenv.sh' file is responsible for telling tomcat where the JRE_HOME is located and other JVM memory options.
I have a couple of things to lock down, but I will be writing up a CentOS/Tomcat/Railo guide. Not that we need another one as they're pretty much the same instructions listed here along with the same resource links that I listed there as well. However, I threw one more thing into the mix. When I was at CFUnited, I managed to score a copy of Fusion Reactor. David Tattersall and crew was there next to the Railo booth and I watched / listened and pestered. I'm also going to get a twitter/plurk friend of mine get involved to get her thoughts on Fusion Reactor as well because I believe that a CF/Server Admin that can herd turkeys and servers for a living has to have some thoughts on Fusion Reactor.
