Ask for tutorials about how to port OpenJDK to a new, architecture/operating system

[James Falknor]

frank wong,
You say that you are using Solaris on a new kind of achitecture. There 
is but four architectures that Solaris runs under: Sparc, Sparc 64-bit, 
x86, and x64.

Since Solaris is under Development by Oracle, and Java is under 
Development by Oracle, and Solaris is only available for Sparc and x64 
based architectures, then why not just use the latest release of Java 
for Solaris from Oracle's web site? Java is available for Solaris Sparc, 
Sparc 64-bit, x86 and x64.

If I'm not mistaken, current releases of Java from Oracle have OpenJDK 
development roled into it.

Since Java for Solaris is already available for the four different 
architecture types of Solaris, then OpenJDK for Solaris ought to already 
be available for the same architectures.
