 Using the Java Native Interface with C++
Native.java This is the public interface that Java uses to interact with the native C++ functions.
There is basically one Java file that implements the interface to the native C++ code and one C++ file that implements all of the examples.
Programming with the Java Native Interface This is a tutorial that shows how to use C++ with the Java Native Interface on Linux, Solaris, and Windows NT.

 Java Native Interface - Wikipedia, the free encyclopedia
The Java Native Interface (JNI) is a programming framework that allows Java code running in the Java virtual machine (VM) to call and be called by native applications (programs specific to a hardware and operating system platform) and libraries written in other languages, such as C, C++ and assembly.
The JNI framework lets a native method utilize Java objects in the same way that Java code uses these objects.
A native method can create Java objects and then inspect and use these objects to perform its tasks.

 Java AWT Native Interface - Wikipedia, the free encyclopedia
In fact, the Java 3D API extension to the standard Java SE JDK relies heavily on the AWT Native Interface to render 3D objects in Java.
Java AWT Native Interface is an interface for the Java programming language that enables rendering libraries compiled to native code to draw directly to a Java Abstract Windowing Toolkit (AWT)
It's interesting to note that the AWT Native Interface requires the "jawt.dll" (or "jawt.so") to run with the application, so the easiest way to do that is copying the "jawt.dll" (should be in the.../jre/bin file path of the JDK's installation path.)

 JNI - Java Native Interface
When executing in native methods you are a long way from the protections of the Java environment (security manager, byte code verifyer, etc) so the overall program may be less reliable.
For example, a Java program that relies on a native Windows' method doesn't need to be altered or recompiled to run on a Solaris machine.
The environment pointer passed to a native method refers to an array of JNI functions for interfacing between the JVM and native code.

 Gamasutra - Features "Dirty Java: Using the Java Native Interface Within Games" [06.11.99]
In both cases, it is the interface to native code that you end up dealing with the same glue that is required to make Java work on your PC in the first place.
Java CPUs have not yet conquered the market, so software must translate Java instructions into the language the PC hardware can understand.
Technologies like Java's just-in-time compilation and HotSpot optimization originate in the Java technology mainstream, and they are powered by more resources than a single game company could ever command.

 A Brief Introduction to Java Native Interface
Native methods are functions written in a language other than Java.
Due to this, many organizations are currently evaluating how to integrating Java efectively to their existing software processes.
The last two things to do are filling in the functionality for Java_sample_sum which you need to write in native code and compiling the source file to a shared library.

 Enhance your Java application with Java Native Interface (JNI)
The solution, of course, is to use Java Native Interface (JNI) extensions.
Admittedly, Java has other benefits: the language is easy to learn and use, the code is simple to maintain and debug, and by using it you leave open the possibility of migrating to other platforms in the future -- if you design your application with such migration in mind.
Although the functions assume C-calling conventions, the header files are C++-aware, and are easier to work with in C++, which, like Java, is an object-oriented member of the C family.

 CIOL : Java : Calling functions using Java Native Interface
A Java file, Java header file, C file and DLL need to be created.
Note that the two arguments are not there in declaration in the Java file, instead they are there in the header file for every function.
Java code can also be invoked from C or C++ but you need to load the Java Virtual Machine in C or C++ program.

 CodeNotes® - Article Display
The Java Native Interface (JNI) provides a way to break out of the interpreted code environment of the JVM and into the fully-compiled world of either C or C++.
In other words, Java saves you the trouble of trying to figure out if a Java int is equivalent to a GNU CC int on a Linux platform.
The various header files in the jdk1.3\include and jdk1.3\include\OS directories define the correct mapping of the Java primitive to the C or C++ equivalent for that operating system.

 Go native with Java Native Interface
The native method signature must provide a header file that satisfies some specific rules, so it's usually easier to generate it using the javah tool instead of building it by hand.
However, any native code must be declared with the native keyword and must be a member of a Java class.
In the former case, jclass represents a reference to the class object, while in the latter, it’s a reference to the object for which the method was invoked.

 Virtual machine - Wikipedia, the free encyclopedia
PVM (Parallel Virtual Machine) and MPI (Message Passing Interface) are two common software packages that permits a heterogeneous collection of Unix and/or Windows computers hooked together by a network and used as a single large parallel computer.
In general terms, a virtual machine in computer science is software that creates a virtualized environment between the computer platform and the end user in which the end user can operate software.
Virtual machines can also perform the role of an emulator, allowing software applications and operating systems written for another computer processor architecture to be run.

 The Java Community Process(SM) Program - JSRs: Java Specification Requests - detail JSR# 40
The Java Metadata Interface specification will address the need for a pure Java metadata framework API that supports the creation, storage, retrieval, and interchange of metadata.
These interfaces (the Meta-Object Facility, or MOF) are specified in IDL, and although the OMG has defined an IDL-to-Java mapping, the resulting Java code produced is neither intuitive or stable.
The existing metadata APIs are either proprietary or are not Java-based.

 Java programming language - Wikipedia, the free encyclopedia
Java is an object-oriented programming language developed by James Gosling and colleagues at Sun Microsystems in the early 1990s.
Java can be considered a less pure object-oriented programming language than for instance Ruby or Smalltalk because it makes certain compromises (such as the fact that not all values are objects) for performance reasons.
Java was intended to serve as a novel way to manage software complexity.
