Hi, It looks like the TinyOS Java libraries are not in your classpath. There should be a tinyos.jar file somewhere, and the CLASSPATH environmental variable should point to it.
You can try something like: export CLASSPATH=.:$TOSROOT/support/sdk/java/tinyos.jar java net.tinyos.tools.Listen -comm serial@/dev/ttyUSB0:telosb Cheers, Urs On 11/15/11 3:25 AM, Baudry Arthur wrote: > Thank you for your support. > I have compiled listen.java using javac, it worked but if I execute > the same command as previously : > java net.tinyos.tools.Listen -comm serial@/dev/ttyUSB0:115200 > > Now I get : > > Exception in thread "main" java.lang.NoClassDefFoundError: > net/tinyos/packet/Packetizer > at net.tinyos.packet.BuildSource.makeSerial(BuildSource.java:241) > at net.tinyos.packet.BuildSource.makeArgsSerial(BuildSource.java:230) > at > net.tinyos.packet.BuildSource.makePacketSource(BuildSource.java:138) > at net.tinyos.tools.Listen.main(Listen.java:56) > > Any thoughts ? > > On 11/14/11, Modi, Jenis Ashokkumar<[email protected]> wrote: >> Hi Arthur, >> Chech whether Listen class is located at that location, also check if it's >> java file is available.
