Great! Hope you like the examples.
There is also a Makefile in the examples dir when you build from CVS
that generates an examples.zip file with everything you need 9which
should be installed if you run from an installation). And there is a
README in the examples dir that should give you all instructions you
need when doing it by hand (attached).
Cheers,

This directory contains example programs that show how the GNU Classpath
library can be used.
Each example has its own package under gnu.classpath.examples and has a
class Demo which contains a main() method to run that particular example.
The examples can be compiled and run with gcj as follows:
gcj -o swingdemo --main=gnu.classpath.examples.swing.Demo \
gnu/classpath/examples/swing/Demo.java \
gnu/classpath/examples/swing/GNULookAndFeel.java
./swingdemo
Or with a traditional byte code interpreter like:
gcj -C gnu/classpath/examples/awt/Demo.java
gij gnu.classpath.examples.awt.Demo
The installation also comes with an examples.zip archive that contains
all needed resources and compiled byte code class files that can be
run as follows:
kaffe -classpath examples.zip gnu.classpath.examples.awt.Demo
kaffe -classpath examples.zip gnu.classpath.examples.swing.Demo
The jawt Demo needs some extra support library that currently needs to be
build by hand. The following assumes GNU Classpath was installed in
/usr/local/classpath, if you installed it somewhere else then adjust the
-I and -L paths accordingly. The included Makefile.jawt is setup this way.
You can invoke it with:
make -f Makefile.jawt
Or you can compile by hand as follows:
gcj -C gnu/classpath/examples/jawt/DemoJAWT.java
gcjh -jni gnu.classpath.examples.jawt.DemoJAWT -o DemoJAWT.h
gcc -g -O0 -Wall -I. -I/usr/X11R6/include -L. -L/usr/X11R6/lib \
-I/usr/local/classpath/include -L/usr/local/classpath/lib/classpath \
-lX11 -ljawtgnu -shared -o libDemoJAWT.so \
gnu/classpath/examples/jawt/DemoJAWT.c
You can then run the example as follows:
export LD_LIBRARY_PATH=.:/usr/local/classpath/lib/classpath
jamvm gnu.classpath.examples.jawt.DemoJAWT
The java2d benchmarking demos include a GTK widget to measure the native
speed of some basic java2d options, without the JNI overhead.
You can invoke it with:
make -f Makefile.java2d
Or you can compile by hand as follows:
gcc -g -O0 -Wall -I./gnu/classpath/examples/java2d \
-o cairobench gnu/classpath/examples/java2d/bench.c \
`pkg-config --libs --cflags gtk+-2.0`
You can then run the example as follows:
./cairobench
