I think I (tried to) answer a question like this just recently...
The javac not found thing is probably because you don't have your
Java SDK bin in your PATH _before_ windows/system32. It might also
be because it's installed in "Program Files" and directories with
spaces in them play havoc with bash shell variables. Try
type java
to see where it thinks it's looking.
As to the cannot find symbol errors, it may be that you don't actually
have a valid jar file at the location specified in your CLASSPATH. Try
jar tvf [path-to-tinyos.jar]
to see if it's got good stuff in it.
Forward slashes and semi-colons are the correct syntax for CLASSPATH.
The bash PATH also needs forward slashes, but uses colon ':' separators.
Search this list over the last couple weeks for PATH and CLASSPATH.
