Frustrating HttpConnection problem

Question

This code was first written (copy/pasted), then run on a laptop (machine 1) in one location. It worked fine. Then the machine was rebooted, the laptop brought to another location, and the code wouldn't run (error messages below). After some searching on the net, I got the impression that the problem was with Eclipse.
So I ran the code on another machine, with the same version of Eclipse (3.1), the same version of the j2me plugin, the same version of Sun WTK and the same j2me version - in other words, an identical installation. It didn't run there either, but the error was slightly different (see below).
Simple code, verified as working by the author (Eclipse 3.1, same version of j2me and WTK as I'm using):

Answer 1

I'm not sure what you mean, but I think the answer is "yes" :-)
However, I noticed after a while that this problem only occurs when I try to run the httpconnection code outside of the actual midlet. When I run it in a midlet, the problems doesn't occur.
