That's a common problem between different Unix flavours. One type
doesn't have any entries for the other's terminal types in it's
temcap/terminfo database, or it knows it by a different name.
You can change your FreeBSD xterms into glorious technicolour by adding:
xterm*termName: xterm-color
to ~/.Xdefaults, and arranging for your .xinitrc (startx) or .xsession
(xdm) to run:
/usr/X11R6/bin/xrdb -merge ${HOME}/.Xdefaults
However, the xterm, even in monochrome, should work correctly for
curses based applications.

Actually, it's not that bad. If you can install the correct terminal
definitions on your linux box, all of those applications should start
to work correctly.

As you've found out, that won't work. The terminal type is determined
by the drivers in the kernel. You've got to use cons25 or one of the
consNN variants in /etc/termcap, depending on what character sets you
want to display and what resolution you run your console at.

The quickest and easiest thing for you to do is install the
misc/screen port, and set it up to use a vt100 terminal type. Just
about everything recognises vt100, and it's practically identical to
xterm anyhow.
Otherwise, you can copy the cons25 and cons25w entries to /etc/termcap
on your linux machine

You need to have a JDK installed in order to compile the native JDK.
The first time you install the native JDK you have no choice but to
install one of the pre-compiled linux JDK's to do that. Once you've
got the native JDK installed, you can delete the linux JDK. You can
use the native JDK to upgrade the native JDK if you set
'NATIVE_BOOTSTRAP=yes' on the make command line (or in pkgtools.conf if
you're a portupgrade(1) afficionado).
Cheers,
Matthew
