Can Harmony compile into Native Executable

I have my Application developed in Swing and would like to compile into Exe?

Are following classes supported in Harmony
java.awt.FocusTraversalPolicy 
MouseInputAdapter

Thanks in advance

yep, and sometimes you do not want your users to know that you are
using java for development. But this should be avoided, IMHO :)

Harmony does not have an AOT compiler. You can try to use other AOT
compilers with Harmony classlib, but this should be a challenge.

P.S.: I am not sure implementation of FocusTraversalPolixy and
      MouseInputAdapter are complete in Harmony, to me they look like
      placeholders..

As an aside, AOT does not guarantee improved performance, it really
depends upon the application.  Modern JITs use profile directed feedback
to guide performance improvements based on runtime information - so in
some cases JIT compiling the code may well improve the execution time.

I'd like to know what you mean exactly.  Do you mean AOT native code
compilation, or just having a stand alone application executable? or
something else?

Tim

Like GCJ does?

java.awt.FocusTraversalPolicy


Yes.

javax.swing.event.

> MouseInputAdapter


Yes.

No, Harmony does not compile Java classes to standalone binaries
today. This technique have
more limitations to Java developer then benefits.

You can use code obfuscator if you want to protect sources.

What do you need exe file for? To avoid "java -jar dfdkjdskhskd.jar
blablabla.Main" command line string or to hide your sources?
