# - Find JNI java libraries.
# This module finds if Java is installed and determines where the
# include files and libraries are. It also determines what the name of
# the library is. This code sets the following variables:
#   
#  JAVA_AWT_LIB_PATH     = the path to the jawt library
#  JAVA_JVM_LIB_PATH     = the path to the jvm library
#  JAVA_INCLUDE_PATH     = the include path to jni.h
#  JAVA_INCLUDE_PATH2    = the include path to jni.h
#  JAVA_AWT_INCLUDE_PATH = the include path to jawt.h
#
