Learning Java [using netscape to compile java]

using netscape to compile java

Netscape Navigator version 3.01 for UNIX has an undocumented feature that allows you to run non-graphical java code files without starting the browser.

The reason that java class files which make use of graphics can not be run with this feature is down to the way in which the AWT (Graphics part of Java) makes use of peers that are dependant on the underlying machine architecture and implementation of the java. Or more simply Netscape provides the AWT layer, but uses different peers.

This is what you need to need to do in order to run java

Get hold of the Sun supplied JDK
Copy the file classes.zip from the JDK into the same place where the Netscape data files are kept (something like /usr/local/lib/netcape). The file names are different (You might like to check, just in case) so theres no likelyhood of overwriting essential files.
You need to set up a few environment variables to make sure netscape knows where the java compiler can be found. In straight forward bourne shell this looks like
NETSCAPE_DATA_DIR=/usr/local/lib/netscape NCLASSPATH=.:$NETSCAPE_DATA_DIR/java_30:$NETSCAPE_DATA_DIR/classes.zip export NCLASSPATH
You're ready to run java class files
netscape -java .....

And to compile java, you need to utter

netscape -java sun.tools.javac.Main -verbose java source files

Now thats sorted, there's nothing to stop you writing and compiling java on virtually any architecture.

Robotics nuts!

Check out http://users.frii.com/dlc/robotics/projects/botproj.htm from Dennis Clark. This guy ROCKS! He has made (and sells but also releases code, docs, etc...) for a number of cool little robotic modules including whiskers, IR proximity detect and remote control, Sonar proximity detect, PWM, Servo, compass. Most of these use the little PIC 12C508 controller which costs basically nothing and is soooo tiny.
The 4 servos, 2400 baud serial servo controller is a wonder of magic and he sells the programmed chip for $8. Wow!
