Hi all,
 
I am trying to work on a project that is to gather the acoustic signals and then display the data on the PC.
 
I am able to gather data, but the problem is when trying to display the data. ( i am listening to the serial port)
 
I had problems using the listen tools in java and the serial forwarder(SF). I need help from u guys.
 
When i am using the SF, i am able to see that the count on the number of packets is increasing, but when i am trying to read that data on to a text file ( surge> 125 example.txt) no data is being written in to that file.
 
Also, when i tried to use the listen and listenraw tools in java, i am getting the following error,
 
 
java net.tinyos.tools.listen
Exception in thread "main" java.lang.NoClassDefFoundError: net/tinyos/tools/listen <wrong name: net/tinyos/tools/listen>
  at java.lang.ClassLoader.defineClass1<Native Method>

  at sun.misc.Launcher$AppClassLoader.loadclass<Unknown Source>
  at java.Lang.ClassLoader.LoadClass<Unknown Source>
  at java.lang.ClassLoader.loadClassInternal<unknown Source>
 
 
I appreciate your help.
 
Thanks,
vijay
