First you install a Java Development Kit.
Then you either go through all the TOS install procedures,
or just copy the files I listed above into the JRE in that
JavaDevKit directory. Once you have something that works
under cygwin or the Linux shell, you use the same JDK/JRE
with Eclipse (and include the tos jar file in your build).
I think Eclipse will use the JDK that is in your PATH variable.
If on Windoze you can set that through the
ComputerManager->SystemProperties panel,
although installing a JDK should do that for you.
There are also settings panels in Eclipse to select Java
versions and JREs if you need to work with different ones.
Aside from the specific libraries needed for GetEnv and
Serial Comm this has nothing to do with TOS, it's all
about getting your JRE setup correctly. One could ask
why Sun thought it NOT a good idea to include GetEnv
(they apparently removed it from System early on) or
any access to I/O ports (who uses I/O these days?) in
their Magical New Universal Programming Environment,
but it would be pointless...
