Java SE (Java Platform, Standard Edition)

Not a complete JavaFX system for openjdk, only parts of it like the ui controls.

----------

If you want to build openjfx with openjdk, use version 8 (as that branch of openjfx includes most of the javafx 8 code) and following the build instructions at:

https://wiki.openjdk.java.net/display/OpenJFX/Building+OpenJFX

for the code at:

http://hg.openjdk.java.net/openjfx/8/master - forest root
http://hg.openjdk.java.net/openjfx/8/master/rt - sub-repo

For version 8:
- there is active ongoing development
- there are comprehensive build instructions
- there is a new gradle based build system
- almost all of the javafx code is open source
- many bugs have been fixed since 2.2
- significant new features have been added since 2.2
- development can use new and desirable java8 features like lambdas

On the drawback side:
- java8 won't be stabilized for a few months
- java8 won't have an official release until march next year
- some tools (such as NetBeans 7.3) don't support java8 well

-----------

The openjfk branches dealing with JavaFX 2.2, which works with java7 are:

http://hg.openjdk.java.net/openjfx/2.2/master
http://hg.openjdk.java.net/openjfx/2.2/master/rt

Building using JavaFX 2.2 with Java 7 is not advised because, for the 2.2 branch:
- the code has hardly changed in 8 months
- only contains a relatively small portion of open source code for javafx project
- there is no significant active development on it
- there are no published build instructions for it anymore

thanks a lot
then I will have a try . javafx2.2 ~
