You may be using the wrong (older) version of Java,
or worse, compiling with one version and running with another.
I suspect that TOS requires 1.5++. "type java" and/or "which javac"
may provide clues.
I hate GUI's...

Hi to all.
We are two students of the Technical University of Catalonia (UPC).
We're getting started in the tinyOS environment. The situation is the
following: we are working with tinyOS 2x (Beta version) under Ubuntu
7.04 Operative System. We are doing the tutorials of tinyOS 2x (tinyOS
web page) and we've arrived to the lesson 5 and we have a problem at the
end of the lesson.
As first step we've compiled Oscilloscope application:
[EMAIL PROTECTED]:/opt/tinyos-2.x/apps/Oscilloscope$ make telosb
mkdir -p build/telosb
compiling OscilloscopeAppC to a telosb binary
ncc -o build/telosb/main.exe -Os -O -mdisable-hwmul -Wall -Wshadow
-DDEF_TOS_AM_GROUP=0x7d -Wnesc-all -target=telosb
-fnesc-cfile=build/telosb/app.c -board= OscilloscopeAppC.nc -lm
compiled OscilloscopeAppC to build/telosb/main.exe
14660 bytes in ROM
380 bytes in RAM
msp430-objcopy --output-target=ihex build/telosb/main.exe
build/telosb/main.ihex
writing TOS image
And we've installed the Oscilloscope application in three motes:
[EMAIL PROTECTED]:/opt/tinyos-2.x/apps/Oscilloscope$ make telosb reinstall,n
tos-set-symbols --objcopy msp430-objcopy --objdump msp430-objdump
--target ihex build/telosb/main.ihex build/telosb/main.ihex.out-1
TOS_NODE_ID=1 ActiveMessageAddressC$addr=1
found mote on /dev/ttyUSB0 (using bsl,auto)
installing telosb binary using bsl
tos-bsl --telosb -c /dev/ttyUSB0 -r -e -I -p build/telosb/main.ihex.out-1

rm -f build/telosb/main.exe.out-1 build/telosb/main.ihex.out-1
In a fourth mote we've installed the BaseStation application and we've
started the SerialForwarder like tells the tutorial:
java net.tinyos.sf.SerialForwarder -comm serial@/dev/ttyUSB0:telosb
Next we've compiled the java application and we obtain seven warnings:
[EMAIL PROTECTED]:/opt/tinyos-2.x/apps/Oscilloscope/java$ make
javac *.java
----------

7 problems (7 warnings)jar cf oscilloscope.jar *.class
Finally we've tried to run the Oscilloscope GUI application and we have
several errors whose reason we don't understand and we're not able to
solve:
[EMAIL PROTECTED]:/opt/tinyos-2.x/apps/Oscilloscope/java$ ./run
Exception in thread "main" java.awt.AWTError: No suitable parent found
for Component.
at javax.swing.JColorChooser.createDialog(libgcj.so.70)

at Window.setup(Window.java:160)
at Oscilloscope.run(Oscilloscope.java:54)
at Oscilloscope.main(Oscilloscope.java:126)
What is the problem?
What can we do to solve this?
We would very grateful for your help.
