We support multiple configurations, but everything doesn't always work
together or make sense.  If you want to write to ANTSR then you can do
this by using janosvm or a regular jvm on a unix box.  If you want to
write to the java nodeos api, then you can use the version that runs on a
regular jvm on unix or the version that runs on a bare machine using the
oskit/moab/janosvm configuration.  Also, the oskit/moab/janosvm
configuration is the only that supports resource controls.

You can, but you won't be able to do anything particularly useful.  The
problem is that ANTSR doesn't directly support multiple interfaces, a
severe deficiency for a routing platform.  However, when ants is run on a
regular unix machine it can rely on the builtin udp/ip stack to perform
the necessary routing through different, whereas the oskit/moab/janosvm
config has no such component.

The jnodeos built for "oskit/moab/janosvm" is designed especially for this
configuration.  It uses native functions in janosvm and moab to perform
network i/o and many other functions.

It is possible to build a jnodeos for a pure java environment, you should
be able to do this directly.  In fact, the ants distribution should
already contain a precompiled jnodeos that works with a regular jvm
(although i haven't tried it with jdk1.4, the janosvm can be compiled to
work on unix and you should be able to atleast use that.)
