[Tinyos-help] could not find the javax.comm classes.....

toscheck checks for the existence of the java xcomm libraries by
building a test java class with a javax comm class and ensuring that
javac can compile it. If javac can't find that class, the test fails.

So I'm guessing that you do have it, but the java binaries that are
getting invoked on your system isn't the one that our tinyos installer
installer. To check if this is the case, type 'which java' and make
sure that the result is something that comes from the installed tinyos

$ which java

and not something from WINNT or some other previously installed java.
