You need to download these files manually, because Sun's licensing requires
that you click on the "I agree" button on their website prior to downloading
the files.  There are about 4 or so that you have to get like this.  It's
a royal pain, but it's Sun's decision, not FreeBSD's.

Where did you get that information?  I installed the entire Java platform
for FreeBSD just two days ago and was able to get all the files I needed.
I've not heard/seen any information about vulnerabilites in jdk14.

Java is probably the most difficult thing to get installed/running
on FreeBSD, however, the port makes it as easy as is possible.  The
following procedure has always worked for me:
cd /usr/ports/java/jdk14
make install
... wait ...
You will get an error about a missing file that you have to download
manually, follow the instructions to get the file, then do "make install"
again.  You will get another error about another missing file that you
have to manually download ... follow the instructions and start "make
install" again ... you'll get another error ... and so on.

Eventually, make install will complete and you'll have a usable Java.

Be very careful when downloading the required files.  It seems as if
Sun has a million Java distributions available for download, and all of
their names are _almost_ the same.  Make sure you're getting the correct
file each time.

> How i can help FreeBSD community???

Email Sun and politely ask them why they are making it so difficult to
install Java on FreeBSD.  Tell them that FreeBSD is your preferred
platform for running Java and you'd like it if it weren't so difficult
to install.
You can also contact the FreeBSD Foundation, which has done a LOT of
work to get the FreeBSD+Java thing this far.  Ask them how you can
help make it even easier.
