[Tinyos-help] I have a question about tinyscript

[Hover Dong]

I am in the dictionary of /opt/tinyos-1.x/apps/BomblliaMica. I input "make pc" to compile it for Tossim. Then I create reboot.txt which content is "led(1);" in the dictionary(BomblliaMica). Then I input the command "$ java net.tinyos.script.Scripter -comm tossim-serial reboot reboot.txt" in command line. Then a error occurred. The error message is as below:
 
ShuHao Dong at camslaptop-21 /opt/tinyos-1.x/apps/BombillaMica$ java net.tinyos.script.Scripter -comm tossim-serial reboot reboot.txtCouldn't instantiate tossim packet sourceDid you compile tossim?java.lang.NullPointerExceptionjava.lang.NullPointerException        at net.tinyos.message.MoteIF.init(MoteIF.java:164)        at net.tinyos.message.MoteIF.<init>(MoteIF.java:134)        at net.tinyos.script.Scripter.main(Scripter.java:114)
ERROR: Could not create a Scripter. Are you in an application directory?
Dose someone have any idea about it? I real appreciate it.
