Java.net (1.4 Spesifications) Incompatible

I have successfully installed blackdown 1.3.1 on my Zaurus SL-C3100, and I´m trying to run a program originally intended for java 1.4.x and above...

My problem is this:
java.lang.NoClassDefFoundError: java/net/SocketAddress
at....
at....
and so on.

After some searching I found that the problem is this:
SocketAddress is apparently a java 1.4 spesific class, and has been reorganized from the jnet package in java 1.3.

So is it possible to download some libraries or packages, for a workaround so that I don´t have to reprogram everything? Could someone direct me in any direction, as I´m currently quite stuck...

Thanks

Newbie Need Internet Browser

Hi. I´ve been trying to get an internet browser for my newly aquired z sl-c3100. Through some trial and error I´ve downloaded 3 broken ipk-files and met a dusin broken links. It may be just me, but I haven´t found any easy-to-follow links for installing an internet browser.

Could anyone please help me with this. Links to downloadable software and a small walkthrough is much appretiated.

Thanks

Alternative To Bluez ?

I have just recieved the 3100 Z for å project at work. I found that we also had a Billionton CF Bluetooth card laying around doing nothing, so I figured I´d try to make it work.

I was looking at the BlueZ package, and I see that it is "not supported" on their list of supported cards. So I was wondering if there´s an alternative to BlueZ?

Can anyone point me in the right direction?

Thanks.
