JNI or no JNI, you can't get it from the System properties. From Java's point
of view, endianess is a non-issue, and is handled internally, therefore, why
would it be in the System properties (and it's not you can print them out
yourself and see)? Basically, if you need to find out the endianess of the
system dynamically, you'll have to do it with native code.
Unless you meant look at the os.arch system property, which may or may not
be a reasonable solution depending on your needs. In general, there's probably
a simple way to find out on-the-fly endianess via native code, without depending
on the location of macros in the os header files (because in that case, you
might as well use os.arch).
