Talk:Java
J2ME and JavaME
Now called JavaME... all this work on the language since the GPLing of Java has gotten Sun to realize how bloated their version is.
CDC and CLDC
The CDC is ~10M that implements all the key parts of Java. Getting an existing Java package (that might use Swing, for instance, which is not in CDC) to run under it should be much much faster than a port to Python. CDC implementation: phoneME.
GCJ and Eclipse
GCJ can compile eclipse. It's an AOT rather than a JIT... it makes hacking less interesting, but a crosscompiling toolchain could be most useful.
SWT
Eclipse is built on this. Many people bring in SWT bindings for their platform (like GTK on Linux).
OSGi
Remote fetching of functionality, allowing that to start/stop services and export this. You can manipulate dependencies between them... including calls out to find the start/stop routines. Talking to CDC about how to make lightweight apps and use cases (and libraries?) work together in a 'just in time' environment.
See this n800 page for more on implementing OSGi and CDC at once.
Graphics acceleration
See OpenGL ES and what the n800 w/CDC is doing.

Java IDE for OLPC?
Does anyone know here of a Java IDE that would be light for OLPC?
Drop GCJ
I would say, if there is no space, lets drop GCJ and that is done. I likely have right to say so after two years of contributing to GNU Classpath when Java was not free. Sun's implementation is now FOSS and we should benefit from it. We must also realize that Java is no longer pushed by Sun as it used to be and if we do not push themselves we will miss the opportunity to have use of one of the most serious contributions ever made to the Free World.
Java is bundled with many tools and some of these seem not required in OLPC. Surely we need runtime environment and for the sake of Free Software we need a compiler. To produce .jar archives for applets, etc we need a zip tool that is likely already included. I suggest to drop all the rest.
About one third of standard Java classes can also be dropped if we do not violate any law by doing this. CORBA is not seldom used even by the most advanced developers, for instance. 82.130.71.234 08:17, 3 November 2009 (UTC)
