Comments on: Deploying Standalone JavaFX Applications Without Runtime Dependencies

@viktorn: No idea really. I have just run it on a legacy system (Celeron 2GHz/512MB RAM/Radeon 9550) with commit charge exceeding the physical memory size thanks to the memory pig called Firefox, and although it took almost forever to start it was responsive after that.

My only guess it that it may be JITting some classes on your system. You can check that as follows:

Modify the executable header to enable console. If you have Excelsior JET installed, just run
gui - JavaFX-1.2-samples.exe in the samples installation directory.

Run the sample using a bat file:
set JETVMPROP=-Djet.jit.loud JavaFX-1.2-samples.exe displayshelf.Main
On my system, it says:
JITCompiler: compile $Proxy0 JITCompiler: compilation finished in 31ms, classes: 1 *** JIT: $Proxy1 JITCompiler: compile $Proxy1 JITCompiler: compilation finished in 31ms, classes: 1 *** JIT: $Proxy2 JITCompiler: compile $Proxy2 JITCompiler: compilation finished in 16ms, classes: 1 *** JIT: $Proxy3 JITCompiler: compile $Proxy3 JITCompiler: compilation finished in 31ms, classes: 1 *** JIT: $Proxy4 JITCompiler: compile $Proxy4 JITCompiler: compilation finished in 32ms, classes: 1 JITCompiler: total compilation time: 141ms, classes: 5
I would say 141 ms is negligible.

@lukazb, Ole: That’s a very good question. It seems that I was a bit ahead-of-time (pun intended) with this announcement. For some reason, I assumed that the JavaFX Runtime license allows redistribution, just like the JRE binary license, especially given the Sun’s promises to open-source it. Now I see that it is not the case, in particular due to third-party code such as media codecs, and Sun has other things to do at the moment, so I do not see this resolving any time soon.

That’s cool!

Any idea why the DisplayShelf sample is so sluggish? The other samples run very smoothly (for being JavaFX)..

Sounds great! But I wonder the same as lukaszb; how is the javafx redistribution licensing handled?

regards!

This would be what I was looking for, for a long time. But how is the licensing of javafx jars handled? As far as I know, you cannot redistribute javafx jar(s), so the only option is to let them be downloaded on application start, via JNLP preferably. I run Mac OS X so I cannot see Excelsior JET at work my self.
