Hi,
I am installing the tinyOS linux ubuntu. Basically I can successfully
compile and install the tinyOS program. But when I tried to run a java
program, such as SerialForwarder it gave me the following error:
Exception in thread "main" java.awt.AWTError: Cannot load AWT toolkit:
gnu.java.awt.peer.gtk.GtkToolkit
at java.awt.Toolkit.getDefaultToolkit(libgcj.so.70)

I also found out that other java program is also not working, like the
TestSerial program. The error when I was running TestSerial (java) program
is as follows:
Exception in thread "main" java.lang.NoClassDefFoundError: TestSerial
at gnu.java.lang.MainThread.run(libgcj.so.70)
Caused by: java.lang.ClassNotFoundException: TestSerial not found in
gnu.gcj.runtime.SystemClassLoader{urls=[file:/opt/tinyos-2.x/support/sdk/java/tinyos.jar],

at java.lang.ClassLoader.loadClass(libgcj.so.70)
at java.lang.ClassLoader.loadClass(libgcj.so.70)
at gnu.java.lang.MainThread.run(libgcj.so.70)
Is there anything that is missed here, like installing the package, setting
the environment or whatever?
Thank you in advance for your help.
Best Regards,
Bayu
