Possible Errors

Note: These are all the errors i faced while running Tiny OS in Ubuntu 11.10.

1. While running "java net.tinyos.tools.PrintfClient -comm serial@/dev/ttyUSB0:telosb" you may get the following error.

The toscomm JNI library was not found. check that your tiny-os package is installed and try rerunning tos-install-jni

Can solve this by the following method.

  (a) Open the bashrc file.
          vim ~/.bashrc
  (b) Add path for the jre binaries.
       Add this line at the bottom most part of bashrc file with out double quotes.
         "export PATH=/usr/lib/jvm/java-6-sun/jre/bin:$PATH"
  (c) Run this command.
         "tos-install-jni"
  (d) Enjoy.

2. Error due to java, while running the java command for serial communication.

      Eg:
             java net.tinyos.tools.Listen -comm serial@/dev/ttyUSB0:telosb

      Exception in thread "main" java.lang.NoClassDefFoundError: net/tinyos/tools/Listen
Caused by: java.lang.ClassNotFoundException: net.tinyos.tools.Listen
    at java.net.URLClassLoader$1.run(URLClassLoader.java:202)

    at java.lang.ClassLoader.loadClass(ClassLoader.java:306)

    at java.lang.ClassLoader.loadClass(ClassLoader.java:247)
Could not find the main class: net.tinyos.tools.Listen.  Program will exit.

  (a) Download "java" tar file from the Tiny OS CVS repository: http://tinyos.cvs.sourceforge.net/viewvc/tinyos/tinyos-2.x/support/sdk/java/
  (b) Untar and keep it in /opt/tinyos-2.1.0/support/sdk instead of existing java folder there.
  (c) Go inside the java folder in terminal and give "make" command.
  (d) Enjoy.
