Editing GNU Classpath (section)

== Uses ==
GNU Classpath is used by many [[Free Java implementations|free Java runtimes]] (like [[Kaffe]], [[SableVM]], [[JamVM]], [[Jikes RVM]], and VMKit) because every full-featured Java virtual machine must provide an implementation of the standard class libraries.

Some other uses include:
* The [[GNU Compiler for Java]], which is capable of compiling Java code into native standalone executables.
* GCJAppletViewer<ref>{{Citation | title = GCJ applet viewer | publisher = Koders | url = http://www.koders.com/java/fid00976F58DD49540480F81EB78F2C2492A3393CD1.aspx | access-date = 2009-09-14 | archive-url = https://web.archive.org/web/20090918100934/http://www.koders.com/java/fid00976F58DD49540480F81EB78F2C2492A3393CD1.aspx | archive-date = 2009-09-18 | url-status = dead }}.</ref> for launching [[Java applet]]s from command line if they are not supported by the browser in use.
* [[IKVM]], which integrates Java with the [[.NET Framework]]
* JNode, an operating system for running Java applications. This system is written in Java and assembler only.
* Specialised virtual machines such as [https://web.archive.org/web/20080316045633/http://www.oberon.ethz.ch/jaos/ Jaos] for integration with the [[Oberon programming language]], and [[JamaicaVM]] for embedded systems with real-time guarantees.
* Virtual machines for distributed computing with clusters, having up to 128 processors on [[Myrinet]].<ref>{{Citation | url = http://www.eecg.toronto.edu/jupiter/ | title = EECG | publisher = U Toronto | contribution = Jupiter}}.</ref>
* The [[IcedTea]] project used GNU Classpath as a replacement for proprietary elements of [[OpenJDK]], prior to their replacement upstream.
