+README.txt
+Roger B. Dannenberg
+16 Jun 2009
+updated 2021
+
+This directory implements a JNI library so that Java programs can use
+the PortMidi API. This was mainly created to implement PmDefaults, a
+program to set default input and output devices for PortMidi
+applications. Because it is rarely used, PmDefaults was dropped from
+PortMidi starting with v3. I recommend you implement per-application
+preferences and store default PortMidi device numbers for input and
+output there. (Or better yet, store device *names* since numbers can
+change if you plug in or remove USB devices.)
+
+Even without PmDefaults, a PortMidi API for Java is probably an
+improvement over other Java libraries, but there is very little MIDI
+development in Java, so I have not maintained this API. The only thing
+probably seriously wrong now is an interface to the
+Pm_CreateVirtualInput and Pm_CreateVirtualOutput functions, which are
+new additions.
+
+I will leave the code here, and if there is a demand, please either
+update it or let your needs be known. Perhaps I or someone can help.
+ 
+==================================================================
+
+BUILDING Java EXTERNAL LIBRARY
+
+You must have a JDK installed (Java development kit including javac
+(the Java compiler), jni.h, etc.
+
+Test java on the command line, e.g., type: javac -version
+
+Enable these options in the main CMakeLists.txt file (run CMake
+from your top-level repository directory):
+     BUILD_JAVA_NATIVE_INTERFACE
+In my Ubuntu linux with jdk-15, ccmake was unable to find my JDK, so
+I have to manually set CMake variables as follows (type 't' to see
+these in ccmake):
+    JAVA_AWT_INCLUDE_PATH  /usr/lib/jvm/jdk-15/include
+    JAVA_AWT_LIBRARY       /usr/lib/jvm/jdk-15/lib
+    JAVA_INCLUDE_PATH      /usr/lib/jvm/jdk-15/include
+    JAVA_INCLUDE_PATH2     /usr/lib/jvm/jdk-15/include
+    JAVA_JVM_LIBRARY       /usr/lib/jvm/jdk-15/lib
+Of course, your paths may differ.

+---- old implementation notes ----
+
+For Windows, we use the free software JavaExe.exe. The copy here was
+downloaded from 
+
+http://software.techrepublic.com.com/abstract.aspx?kw=javaexe&docid=767485
+
+I found this page by visiting http://software.techrepublic.com.com and
+searching in the "Software" category for "JavaExe"
+
+JavaExe works by placing the JavaExe.exe file in the directory with the
+Java application jar file and then *renaming* JavaExe.exe to the name
+of the jar file, but keeping the .exe extension. (See make.bat for this 
+step.) Documentation for JavaExe can be obtained by downloading the
+whole program from the URL(s) above.
