As some of you know I've been working on a Lego Mindstorms book for Java
programmers. The official release date is March 15, 2002 so it seems like a
good time to announce it. The intent of this book is to get Java programmers
interested in Lego Mindstorms robotics. The title of the book is "Core Lego
Mindstorms Programming", part of Cay Horstmanns Core series with Prentice
Hall PTR.
Dear Brian
I have ordered my copy from Amazon. Looks very interesting. One question -
is it compatible with Java version 1.3?
With best wishes

Yes, it's 100% compatible with the latest versions of the Java SDK. I use
1.3.1 myself and it works great. There were originally some problems with
the SDK 1.4 beta but those have been worked out.

I assume with the offfical 1.4 release? I have had several problems with
the offical release including stability problems, incompatible code (some
wierd 1.2 stuff), slow performance, and hanging event threads (they never
return from calling the event methods). I think I will wait for 1.4.1. :)

I have made the necessary modifications to leJOS
(there was a clash with the new assert keyword) and
then tried the Java SDK 1.4 with a few tests, it worked.
What you have to do is use the CVS version and add "-target 1.1"
as an option to lejosc and javac whenever you are compiling
for the leJOS linker, because it only understands 1.1 classfile format.
Regularly I use 1.3
BTW, I hope you always read the licenses:
5. Notice of Automatic Software Updates from Sun. You
acknowledge that the Software may automatically download,
install, and execute applets, applications, software
extensions, and updated versions of the Software from Sun
("Software Updates"), which may require you to accept updated

Anybody got a Linux sandbox w/o internet access for this rascal?

You have to wonder how the SDK could possibly do that. The only opportunity
I can see for it doing this is with the binary files javac and java, but I
doubt they have auto-update features. Maybe the applet JVM has this?
p.s. Kudos for reading the license. You are probably the first person to do
so since the SDK was released. ;)
