Directorio que aloja todos los archivos JAR que no contienen o usan código nativo y no dependen de una versión estándar de Java concreta. Los archivos JAR se pueden situar directamente en este directorio o en uno de sus subdirectorios. Con frecuencia los paquetes crean sus propios subdirectorios allí, en este caso el nombre del subdirectorio debería coincidir con el nombre del paquete.

Directory where architecture-specific JAR files are installed. In particular, JAR files containing or using native code (Java Native Interface, JNI) should be installed there.

Root directory where all Java API documentation (Javadoc) is installed. Each source package usually creates a single subdirectory containing aggregated Javadocs for all binary packages it produces.

Directory where Project Object Model (POM) files used by Apache Maven are installed. Each POM must have name that strictly corresponds to JAR file in %{_javadir} or %{_jnidir}.

Directory where ivy.xml files used by Apache Ivy are installed. Each XML must have name that strictly corresponds to JAR file in %{_javadir} or %{_jnidir}.

Root directory where different Java Virtual Machines (JVM) are installed. Each JVM creates a subdirectory, possibly with several alternative names implemented with symbolic links. Directories prefixed with java contain Java Development Kit (JDK), while directories which names start with jre hold Java Runtime Environment (JRE).

Directories containing configuration files for Java Virtual Machines (JVM).

Directories containing implementation files of Java Virtual Machines (JVM). Describing them in detail is out of scope for this document. Purpose of each directory is commented briefly in macros.jpackage file in /etc/rpm. More detailed description can be found in JPackage policy.

Directory containing Java configuration files. In particular it contains main Java configuration file — java.conf.
