== Packaging JAR files that use JNI ==
+=== Writing general spec file ===
+Keep in mind that your package should build under different flavors of Java. In order to achieve this, you have to instruct the C preprocessor to search for header file in the include subdirectories under <code>/usr/lib/jvm/java</code>, which is a symlink maintained by the <code>alternatives</code> system.
+(Though file <code>jni.h</code> is
+in the default gcc include path when gcj is used, it is not so for openjdk.)
+
+If the package uses Autoconf-generated configure script, follow this template:
+<pre>
+BuildRequires: java-devel
+[...]
+%build
+for i in -I/usr/lib/jvm/java/include{,/linux}; do
+ java_inc="$java_inc $i"
+done
+%configure CPPFLAGS="$java_inc"
+</pre>
+
=== Applicability ===
Java programs that wish to make calls into native libraries do so via the Java Native Interface (JNI). A Java package uses JNI if it contains a .so
