c/.h files adds the include paths to jni.h and jni_md.h: In the "VM arguments", we add "=jni"so that Java can find the '.so' library. To run a Java file, the run time configuration of the Java file has to be updated.To compensate, the makefile defines a CLASS_PATH variable (./bin), which is used by vpath and javah. If the above doesn't make any sense, read chapters 1 and 2 from the book. The project layout has the following files: However, the makefile target 'all' does both in one step if you didn't add any extra native calls in Java.So when you add java native methods, you need to re-generate your header first (HelloJNI.h makefile target), then use the function prototype in your C file.

h header file contains the glue code between Java and your C file.

You can install the "Eclipse for Java development" and from the market place install the "CDT" plugin ( Tutorial).But you can add additional languages via plugin installation. Eclipse comes in packages designed for certain languages.dnf install groups install "C Development Tools and Libraries".dnf install java-1.8.0-openjdk-debuginfo.x86_64 # for C debugging.dnf install java-1.8.0-openjdk-src.x86_64 # useful to view Java source code.dnf install java-1.8.0-openjdk-devel.x86_64 # contains jni.h.Java Development tools (JDK as oppose to JRE).You require the following packages for JNI development: Eclipse for C development (See ' getting started' from User Guide).Eclipse for Java development ( Tutorial).You don't need to have JNI knowledge as this project can be used to learn about JNI, but reading introduction chapters 1 and 2 from the book first would help you a lot.makefiles ( Tutorial 1, Tutorial 2, Tutorial 3, and quick reference).I shall assume you have some familiarity with the following: Please post comments if you have questions/feedback. This combined with the JNI literature and other tutorials listed at the bottom of this article should help you getting started with JNI development. In this tutorial I will provide a sample project that I glued together based on various tutorials (see further readings) and explain each of the components. Developing, and especially debugging this custom code can be difficult and cumbersome, but it doesn't have to. Further, sometimes you may have custom 'C' code in your Java applications. An example of this is Eclipse's own interface, which on Linux is drawn by a native C library "GTK", thus the native Linux look. JNI is useful in many situations, for example if your Java applications needs to interface with a native C library. This article is focused on the configuration of Eclipse rather than explaining JNI itself, however there are links to JNI literature at the end.

I.e, you can have a single project that can be both Java and C at the same time, and support a full code navigation and debugging of both languages.

In this tutorial style article I'll discuss how to configure Eclipse for Java Native Interface (JNI) development based on a sample project that you can copy and modify. Cross language development in one project
