1. Install tomcat6 via synaptic.

sudo apt-get tomcat6 tomcat6-admin

There may be some tweaks that you need to do after install.  I didn't need to change anything, but you can find help from the ubuntu help page for tomcat.

My development environment varies based on the project that I'm working with.  For my latest project I'm creating a Flex media player and though I started using Gedit, I've moved to Eclipse + Flex Builder so as to take advantage of Flex's Builders code completion feature.  Other features that I needed for this project were support for FTP, Bazaar, PHP, and JQuery.  Here are the steps I took to build the IDE for this project. 

Unfortunately, this was not straight forward task for me, which may be due to my lack of skills. So, in order to ease someone else's pain, I'm posting my method of installing flex builder on Ubuntu 8.10.

1. Download Eclipse 3.3 Europa
   The download link for Europa 3.3 is post worthy in and of itself due to Eclipse Project's troublesome site navigation. I downloaded the Linux (x86/GTK 2) version on to my 32-bit machine (64 bit also available).

If you haven't heard, Adobe recently published the Flex in a Week video series. The bummer for us Linux users is that to watch the videos you need to install AMP, which is not compatible. However, today I found that you can watch the videos if you import the video series xml feed into Miro.

1. Install Miro
2. Go to "Channels"->"Add Channel"
