README Shared Stubs JNI Example ----------------------------------------------------------------------- This directory contains an example demonstrating the use of shared stubs for calling native code from Java(tm) applications. For instance, we show how you could call the function printf from the standard C library with little work. A shared stub is a single JNI native method that can dispatch to many C functions that reside in some shared library (also known as dynamically linked libraries). This is the sample code of a JavaOne'*** presentation. The presentation was titled "Java(tm) Native Interface Technology Programming," and slides from the presentation can be viewed by following links from http://java.sun.com/javaone/index.html For more information about shared stubs, we encourage you to read the source code in this directory; this is an annotated example! Start with the file Main.java. At the time of this writing, we have implemented shared stubs for SPARC based Solaris(tm) and 32 bit Windows(tm) platforms. ---------------------------------------------------------------------- Contents ---------------------------------------------------------------------- We give a short description of the contents of this directory. If you are learning this example, and how it works, it might help to browse the files in the order listed here. Main.java Entry point to this example. Shows how you would call C functions such as printf, scanf, etc. makefile.unix Makefiles for compiling and running this nmakefile example on Solaris and Windows. CFunc.java An abstraction for a C funtion. Users will create an instance of class CFunc, and then do a "callXXX" operation on that instance to cause the real C function to be called. CPtr.java An abstraction for a C pointer that points to an arbitrary C type. Think of an instance of CPtr as a something that represents a "void *". CPtr provides methods that let you indirect the "void *" and get at what is pointed at as a Java data type. CMalloc.java Just a CPtr, but the CPtr represents a C pointer that has been malloc'ed on the C heap. Use this if you have to pass malloc()'ed memory to some CFunc. dispatch.c Implementation of the shared stub native methods. dispatch_sparc.s SPARC specific parts of dispatch.c. dispatch_x86.c Win32/x86 specific parts of dispatch.c. ---------------------------------------------------------------------- Requirements ---------------------------------------------------------------------- To build and run this example you will need one of the following operating systems: - SPARC based Solaris 2.4 (or higher) - Windows NT 4.0 - Windows 95 You will have to install JDK(tm) software, release 1.1 or higher. On Solaris you will need a C compiler (cc or gcc), and tools "as", "ld" and "make", available in /usr/ccs/bin. On Windows, you will need the utilities "nmake" and "cl" from the Microsoft Developer Studio suite of products; however, it should be trivial to create a makefile to run this example with other C compilers. ---------------------------------------------------------------------- Compiling and running ---------------------------------------------------------------------- On Solaris, if you have JDK software installed in /home/user/jdk, type: % make -f makefile.unix JDK=/home/user/jdk On Win32, if you have JDK software installed in c:\jdk, type: C:\JNI_Example> nmake -f nmakefile JDK=c:\jdk The default target runs the example, in addition to compiling it. If you wish to only compile the example, specify the target "build" explicitly at the make command line. ---------------------------------------------------------------------- Comments and feedback ---------------------------------------------------------------------- Please send comments about this example, and JNI in general, to the alias "jni@java.sun.com". We welcome your feedback! Folks on this alias are developers, and will not be able to provide support, but will read comments. For support, please visit the Java(tm) Developer Connection at: http://java.sun.com/jdc If you find any bugs in this example, please send email to the JNI alias. Please file JNI bug reports at: http://java.sun.com/cgi-bin/bugreport.cgi
