3GNU Classpath, Essential Libraries for Java is a project to create a
4free software implementation of the core class libraries for the java
5programming language.

7Additionally, GNU Classpath includes a sub-project called GNU Classpath
8Tools whose goal is to provide a number of free replacements for standard
9Java development tools like javadoc, javap, and others. A sub-project
10called GNU Inetlib, can be used as an extension library to provide extra
11network protocol support (ftp, finger, gopher) for GNU Classpath. It can
12also be used as a standalone to ease adding http, imap, pop3 and smtp
13client support to applictions. These subprojects are normally released
14independently from the core libraries.

16This is a development snapshot release only and is not for general
ac1ed908
MW
17purpose use. GNU Classpath needs to be combined with a proper
18development environment to be useable for end users. Eventually,
f911ba98
TT
19these essential libraries for java will work with as many free
20compilers and runtimes as possible.
21
22Complete development environments known to be based on GNU Classpath
23include (recommended for end users):
24
25 * GCC with GCJ (http://gcc.gnu.org/java/)
26 * Kaffe (http://www.kaffe.org/)
27
28Smaller environments (runtime only, no compilers, no tools) which work
29with this GNU Classpath releases include
30(tested by and recommended for GNU Classpath hackers):
31
4f9533c7 32 * CACAO (http://www.cacaojvm.org/)
f911ba98 33 * JamVM (http://jamvm.sourceforge.net/)
ac1ed908 34 * Jikes RVM (http://jikesrvm.sourceforge.net/)
f911ba98

35
36In general the latest releases of the above VMs will work out of the box
37with the latest GNU Classpath release (and in most cases directly with the
38development sources from CVS).
39
40Besides combining GNU Classpath with the runtimes and compilers above
ac1ed908
MW
41you might want to add support for additional extension libraries (mail,
42activation, infobus, servlet) check out the GNU ClasspathX project
43(http://www.gnu.org/software/classpathx/).

45Some tools come with their own customized version of GNU Classpath.
ac1ed908
MW
46Please check if there is a customized version available for the tool you
47use before trying the bare bones GNU Classpath release. We are working with
f911ba98 48the tool creators to keep the differences between the core classes as small
ac1ed908 49as possible. Please tell us if you make GNU Classpath work with a new tool.

51Active projects which use modified versions of the Classpath libraries
52some of which synchronizes with the Classpath CVS head every couple of weeks:
53
54 * IKVM.NET (http://www.ikvm.net/)
55 * JC (http://jcvm.sourceforge.net/)
56 * JNode (http://jnode.sourceforge.net/)
