I've been looking into Java (getting a feel for it's build process and I've 
determined that the CMAKE_Java_LINK_EXECUTABLE should possibly look 
something like this:

IF(NOT ${CMAKE_Java_LINK_EXECUTABLE})
  STRING(REGEX REPLACE "\/" 
    CMAKE_Java_ENTRY_POINT "<TARGET>")
  SET(CMAKE_Java_LINK_EXECUTABLE 
    "<CMAKE_Java_ARCHIVE> -cf <TARGET> -e <CMAKE_Java_ENTRY_POINT> -C 
<OBJECT_DIR>")
ENDIF(NOT ${CMAKE_Java_LINK_EXECUTABLE})

I know I'm using the STRING() macro incorrectly and was wondering if there 
was a good example of its usage.  This should allow us to get the main 
method into the jar's manifest for a pseudo static linked executable.  I'm 
sure there are other problems with this idea but I'm open to suggestions at 
this point.
