How to build JDK15 on AMD64 with FreeBSD?

[Neo Jia]

All,

These days, I tried to build the JDK15 on AMD64 with Fedora Core 3, but 
failed. And I happened to find out that in these two mailing lists, 
there were many  people who had successfully built it with FreeBSD. I 
hope I could get some detailed information about the building procedure. 
Do you also use the source code from SUN SCSL or another version 
maintained by FreeBSD.org? What is the requirement I should meet to 
build it on FreeBSD, such as the version of FreeBSD? Do I still need GCC 
3.2.2?

Sorry about so many questions at the first time. Your instructions will 
be greatly appreciated!

Thanks,
Neo
