Embedded Linux questions

I am looking to develop a product that will run on a Linux OS.  I have a few pieces to this question...

1) What is the best Linux distro to use for a computer that will have no monitor, mouse, or keyboard attached?  It needs to support USB and Ethernet and be a VERY small OS.  Ability to use a USB WiFi card would be cool.  I believe I need to develop in Java.

2) What is the easiest way develop Java code for Linux?  I'm installing Ubuntu onto my D600 laptop and this is my entire goal for using Linux - for now at least.
The component I am devloping against is described as:
    Description: Port of C Library to Linux 2.4/2.6.
    Requires Sun JRE for Java support (optional).

Any other helpful information you can provide would be great.  I've never developed in Java, but in my former life I did C++ development for PLDs and now I do C# so at least I am familiar with the basic syntax.

I will be putting it onto a disk-on-chip so I would prefer to keep the OS below 100MB.

I'll check out the URLs you referenced.

GumStix can take compact flash, so you have up to 1GB without a lot of effort.

CF actually goes up quite a bit higher than 1GB, however due to physical space limitations there will not be a CF socket only the disk-on-chip.

Holy smokes, I did not realize that Gumstix was a computer rather than just a Linux OS, I'll have to check it out further.

Another system you can try are via-epia boards or the like.
mini-itx or nano-itx systems.
(170x170mm)  (120x120mm)

Gumstix is way smaller though.
(80x30mm)
