Jython programs can import and use any Java class. Except for some standard modules, Jython programs use Java classes instead of Python modules. Jython includes almost all of the modules in the standard Python programming language distribution, lacking only some of the modules implemented originally in C. For example, a user interface in Jython could be written with Swing, AWT or SWT. Jython compiles to Java bytecode (intermediate language) either on demand or statically.
Jython was initially created in late 1997 to replace C with Java for performance-intensive code accessed by Python programs, moving to SourceForge in October 2000. The Python Software Foundation awarded a grant in January 2005. Jython 2.5 was released in June 2009.
Status and roadmap
The most recent release is Jython 2.7.0. It was released on 2 May 2015 and is compatible with Python 2.7.
From version 2.2 on, Jython (including the standard library) is released under the Python Software Foundation License (v2). Older versions are covered by the Jython 2.0, 2.1 license and the JPython 1.1.x Software License.
The command line interpreter is available under the Apache Software License.
Jython is one of two scripting languages (with Jacl) used in WebSphere Application Server. It is used in IBM Rational development tools, where Jython projects can be created using wizards. It is used as the main programming language for the DataMelt scientific computing. The usage of Jython for scientific applications was discussed in the book "Scientific Data analysis using Jython Scripting and Java" by S.Chekanov.
