83.81.144.51: /* Community ports OpenJDK 6 JRE (more info) */

Temporary entry to outline Brainstorm entry for ''Java support on Maemo 5'' [http://talk.maemo.org/showthread.php?t=32914 as result of discussion on t.m.o]. Also see [[Java]]; this wiki entry is permanent and not related to Brainstorm.

== Proposal 1: [http://java.sun.com/javame/ Java ME] ==

=== Nokia buys Java ME royalities and lets SUN port it ===

*+) Official implementation, official support
*+) [http://talk.maemo.org/showpost.php?p=351021&postcount=95 According to a member of the Java Runtime Team] at Nokia, some work on this port has already been done.
*-) Probably quite expensive
*-) Closed license

=== Community ports [https://phoneme.dev.java.net PhoneME] ([http://www.sun.com/software/opensource/java/faq.jsp#c more info]) ===

*+) GPL
*-) No team as of yet
*-) Not "official", so no advertising of MIDP capability
*-) No info as to how complete this implementation is

=== Nokia or the community ports a Java SE implementation, and we use something like [http://www.microemu.org MicroEmu] for ME compatibility ===

*+-) See above
*-) Might be a bit slower

=== Use the Google Android's Virtual Machine Dalvik ===

*+) Open source, fast, mobile phone optimized
*+) It would be great if the Maemo community could profit from all android apps.
*-) Google

== Proposal 2: [http://java.sun.com/javase/embedded Java SE] ==

=== Nokia buys Java SE embedded royalities and lets SUN port it ===

*+) Official implementation, official support
*-) Probably quite expensive
*-) Closed license

=== Community ports [http://openjdk.java.net OpenJDK 6 JRE] ([http://www.sun.com/software/opensource/java/faq.jsp#b more info]) ===

*+) GPL
*+) OpenJDK Port of [http://www.camswl.com/openjdk Cambridge Software Labs] seems to work quite good on N900: [[OpenJDK 6.0_0 (Cambridge Software Labs) on N900]]
*-) No team as of yet
*-) Not "official", so no advertising
*-) No info as to how complete this implementation is

=== Community ports [https://wiki.evolvis.org/jalimo/ Jalimo] ===

*+) GPL
*-) Not much activity lately
*-) No advertising, maybe incomplete

=== Community or Nokia builds [http://icedtea.classpath.org/wiki/Main_Page Iced Tea] ===

*+) True GPL, no binary components
*-) No team so far
*-) No official advertising

== Todo ==

Following is not taken into account in above proposals.

*?) Compatibility of open source implementations with the official one. Certified YES/NO. If no, please link to what is missing.
*?) Browser plugin is not covered in discussion.
