Try "type java" to see where you are getting your Java from.
If it indicates something like "jdk1.5.0_07/bin/java" or
other 1.4, 1.5, 1.6 versions you are probably fine....otherwise
you may need to install a modern JDK.

For Graphviz, if "type dot" doesn't find anything, a file search for
the "Graphviz" directory might turn up something which should go into
your PATH. GV is only used to produce the nice docs diagrams so it's
not a life-threatening thing to be missing. If you didn't get it
installed when you did TOS itself, look through tinyos.net for the
install package.

Hello all,

When I type tos-check-env I have errors and warnings :
tos-check-env completed with errors:
--> WARNING: The JAVA version found first by tos-check-env may not be version 1.
4 or version 1.5one of which is required by TOS. Please ensure that the located
Java version is 1.4 or 1.5
Depending on your PATH environment variable, there is often another  version of
java.exe in c:\windows\system32 that is "seen" first. Check that this is version
 1.4 or 1.5 or reconfigure your PATH environment variable if this is the case.
--> WARNING: No dot in current path.
--> WARNING: tos-check-env could not find the 'dot' executable which is part of
the AT&T Graphviz package. Please install version 1.1.0 of Graphviz if you'd lik
e to use the nescdoc documentation generator. If Graphviz is already installed,
then dot may not be in your PATH.

Can someone Help me to fix these errors ?
