Java application stack
A Java™ application uses the Java class libraries that are provided by the JRE to implement the application-specific logic. The class libraries, in turn, are implemented in terms of other class libraries and, eventually, in terms of primitive native operations that are provided directly by the JVM. In addition, some applications must access native code directly.
The following diagram shows the components of a typical Java Application Stack and the IBM JRE.
![]()
The JVM facilitates the invocation of native functions by Java applications and a number of well-defined Java Native Interface functions for manipulating Java from native code (for more information, see The Java Native Interface (JNI)).
