Hi th...,
that's a thing which is on my list for longer time, too. Maybe I'll create a
patch within the next weeks/month.
One thing you've to mention is the required application layout of CEF
(https://code.google.com/p/chromiumembedded/wiki/GeneralUsage#Application_Layout
). Especially for Mac it isn't that easy going.
Regards, Kai

Hi Kai,
I'm glad to hear this already is on your list. My customer is currently
thinking about replacing his Swing-GUIs with HTML-GUIs that need to run in the
old application Frame. Since the Java FX Web View has an awful JavaScript
Performance the JCEF seems to be the only way to realize this.

I had to do this for our app embedding JCEF. This is something other libraries
such as SWT and JOGL do as well. In our app, we extract to a temp folder, whose
location is persisted by the application. We have a cb-win64.jar, cb-win32.jar,
cb-macosx64.jar with all the appropriate resources.
Here's that code below. You'll probably come up with something optimized for
your build scripts. A few interesting notes:
1. Notice the Mac is a bit special. There's also a list of resources that need
the executable bit to be set.
2. The temp folder must be a location with full privileges on Windows. I'm
saying this because we're using Javawebstart and some of its api's were
pointing to a Windows folder with lower permissions (LocalLow folder, can't
link to dll's outside of this folder, so could not link to jawt.dll).
The app calls extractToLibraryPath on startup. Then it can assumes the jcef/cef
libraries are available to be loaded.
I also used System.loadLibrary with absolute paths instead of relative paths as
JCEF currently does today. This way, we don't need to rely on external
properties, we just need to know where we extracted the libs.
If this doesn't help, please ignore this comment... It's working well for us.
