Re: [Tinyos-help] question about dual platform java CLASSPATH
I think the problem is in your TOS* variables.
I have them set like this:
vincent:schip [207] echo $TOSDIR
/opt/tinyos-1.1.7/tos
vincent:schip [208] echo $TOSROOT
C:/cygwin/opt/tinyos-1.1.7
Because the "/opt/..." syntax is only relevant to programs
which use the cygwin dll. Java does not, so it is probably
not able to follow your TOSDIR setting.

Re: [Tinyos-help] question about dual platform java CLASSPATH
Hi, I failed to understand everything you write but here is a way to set your CLASSPATH. Type the following command and hit enter CLASSPATH=$CLASSPATH:$TOSROOT/support/sdk/java/tinyos.jar:. Now check its effect: echo $CLASSPATH It should print the above directories. As long as you have tinyos.jar in the corresponding directory, tinyos java programs should work. Good luck, Ali ___ Tinyos-help mailing list Tinyos-help@millennium.berkeley.edu https://www.millennium.berkeley.edu/cgi-bin/mailman/listinfo/tinyos-help
[Tinyos-help] question about dual platform java CLASSPATH
Hi all, (i'm sorry about the length of this email) I have been confused by
the setting of CLASSPATH for days.
I have tos1 and tos2 installed according to
http://www.5secondfuse.com/tinyos/install.html
Now i'm trying to use TOSBase to listen to the serial port, here's what
happened:
*
*
*1. when I in tos1. I 'cd' to $TOSROOT/tools/java, 'make' gives me all sorts
of error message. *
*2. the 'listen' feature is not working properly, it gives error message
like this: *
Exception in thread "main" java.lang.NoClassDefFoundError:
net/tinyos/packet/BuildSource
at net.tinyos.tools.Listen.main(Listen.java:47)
Caused by: java.lang.ClassNotFoundException: net.tinyos.packet.BuildSource
at java.net.URLClassLoader$1.run(URLClassLoader.java:217)

at java.lang.ClassLoader.loadClass(ClassLoader.java:266)
at java.lang.ClassLoader.loadClassInternal(ClassLoader.java:334)
... 1 more
*3. when I hope to use 'listen' in tos2, it gives me the same error message.
*
After doing a few research, I think maybe this is because of an error in
CLASSPATH setting.
can any one please tell me how to make it right?
