Apps :: Java on pen drive

I would like to install dsl on a pendrive. The application I want
to use requires Java (JRE). My questions are:
Can JRE be installed on a pen drive?
If so:
What size pen drive would be the better choice?

You just download package from the uci section of the mydsl repository and copy it to the base directory of the pen drive so it loads automatically at boot up. I use a 512MB and a 256MB. No problems with either one.
