+# - 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:
+#
+#  JNI_INCLUDE_DIRS      = the include dirs to use
+#  JNI_LIBRARIES         = the libraries to use
+#  JAVA_AWT_LIBRARY      = the path to the jawt library
+#  JAVA_JVM_LIBRARY      = the path to the jvm library
+#  JAVA_INCLUDE_PATH     = the include path to jni.h
+#  JAVA_INCLUDE_PATH2    = the include path to jni_md.h
+#  JAVA_AWT_INCLUDE_PATH = the include path to jawt.h

+# This file provides functions for Java support.
+#
+# Available Functions:
+#
+#   add_jar(TARGET_NAME SRC1 SRC2 .. SRCN RCS1 RCS2 .. RCSN)
+#
+#   This command creates a <TARGET_NAME>.jar. It compiles the given source
+#   files (SRC) and adds the given resource files (RCS) to the jar file.
+#   If only resource files are given then just a jar file is created.
+#
+#   Additional instructions:
+#       To add compile flags to the target you can set these flags with
+#       the following variable:
+#
+#           set(CMAKE_JAVA_COMPILE_FLAGS -nowarn)
+#
+#       To add a path or a jar file to the class path you can do this
+#       with the CMAKE_JAVA_INCLUDE_PATH variable.
+#
+#           set(CMAKE_JAVA_INCLUDE_PATH /usr/share/java/shibboleet.jar)
+#
+#       To use a different output name for the target you can set it with:
+#
+#           set(CMAKE_JAVA_TARGET_OUTPUT_NAME shibboleet.jar)
+#           add_jar(foobar foobar.java)
+#
+#       To add a VERSION to the target output name you can set it using
+#       CMAKE_JAVA_TARGET_VERSION. This will create a jar file with the name
+#       shibboleet-1.0.0.jar and will create a symlink shibboleet.jar pointing
+#       to the jar with the version information.
+#
+#           set(CMAKE_JAVA_TARGET_VERSION 1.2.0)
+#           add_jar(shibboleet shibbotleet.java)
+#
+#        If the target is a JNI library, utilize the following commands to
+#        create a JNI symbolic link:
+#
+#           set(CMAKE_JNI_TARGET TRUE)
+#           set(CMAKE_JAVA_TARGET_VERSION 1.2.0)
+#           add_jar(shibboleet shibbotleet.java)
+#           install_jar(shibboleet ${LIB_INSTALL_DIR}/shibboleet)
+#           install_jni_symlink(shibboleet ${JAVA_LIB_INSTALL_DIR})
+#
+#        If a single target needs to produce more than one jar from its
+#        java source code, to prevent the accumulation of duplicate class
+#        files in subsequent jars, set/reset CMAKE_JAR_CLASSES_PREFIX prior
+#        to calling the add_jar() function:
+#
+#           set(CMAKE_JAR_CLASSES_PREFIX com/redhat/foo)
+#           add_jar(foo foo.java)
+#
+#           set(CMAKE_JAR_CLASSES_PREFIX com/redhat/bar)
+#           add_jar(bar bar.java)
+#
+#
+#   Variables set:
+#       The add_jar() functions sets some variables which can be used in the
+#       same scope where add_jar() is called.
+#
+#       <target>_INSTALL_FILES      The files which should be installed. This
+#                                   is used by install_jar().
+#       <target>_JNI_SYMLINK        The JNI symlink which should be installed.
+#                                   This is used by install_jni_symlink().
+#       <target>_JAR_FILE           The location of the jar file so that you
+#                                   can include it.
+#       <target>_CLASS_DIR          The directory where the class files can be
+#                                   found. For example to use them with javah.
+#
+#    find_jar(
+#             <VAR>
+#             name | NAMES name1 [name2 ...]
+#             [PATHS path1 [path2 ... ENV var]]
+#             [VERSIONS version1 [version2]]
+#             [DOC "cache documentation string"]
+#            )
+#
+#    This command is used to find a full path to the named jar. A cache entry
+#    named by <VAR> is created to stor the result of this command. If the full
+#    path to a jar is found the result is stored in the variable and the search
+#    will not repeated unless the variable is cleared. If nothing is found, the
+#    result will be <VAR>-NOTFOUND, and the search will be attempted again next
+#    time find_jar is invoked with the same variable.
+#    The name of the full path to a file that is searched for is specified by
+#    the names listed after NAMES argument. Additional search locations can be
+#    specified after the PATHS argument. If you require special a version of a
+#    jar file you can specify it with the VERSIONS argument. The argument after
+#    DOC will be used for the documentation string in the cache.
+#
+#
+#    install_jar(TARGET_NAME DESTINATION)
+#
+#    This command installs the TARGET_NAME files to the given DESTINATION. It
+#    should be called in the same scope as add_jar() or it will fail.
+#
+#
+#    install_jni_symlink(TARGET_NAME DESTINATION)
+#
+#    This command installs the TARGET_NAME JNI symlinks to the given
+#    DESTINATION. It should be called in the same scope as add_jar()
+#    or it will fail.
+#
+#
+#    create_javadoc
+#
+#       Create jave documentation based on files or packages. For more details
+#       please read the javadoc manpage.
+#
+#       There are two main signatures for create_javadoc. The first signature
+#       works with package names on a path with source files:
+#
+#       create_javadoc(
