Are there any plans/timeline for support of the newest release of
XULRunner in SWT?  There are several changes in 1.9.3 I'm eager to get
my hands on.  I know it's still in beta, but I was just wondering if
integration or testing efforts start before the release.

Cheers,
Ryan Levering

Hi Ryan,

I don't think there will be a XULRunner 1.9.3 release, the next
release that I can see is 2.0.  XULRunner 1.9.3 was previously
proposed but I think has been discontinued.

XULRunner 2.0 will have significant API changes compared to pre-2.0,
with no frozen C++/Java interfaces (new policy), and will not ship
with JavaXPCOM jars .  SWT is not planning support for xulrunner
versions >= 2.0, since WebKitGTK+ is available as an alternative for
SWT.NONE-style Browsers.  Support (bug fixes) for xulrunner versions <
2.0 will continue, so swt clients using JavaXPCOM will be supported,
but must continue to prescribe a XULRunner version < 2.0.

Yeah, my apologies on the version.  The bug fixes I was looking at are
still are listed as 1.9.3, but they renamed it to 2.0.

This is very disappointing news.  Is there any equivalent to JavaXPCOM
with WebKitGTK+?  There were a lot of things that could only be done
easily with the Browser using JavaXPCOM (header listeners, etc).

sounds disappointing that mozilla is not supported. but looking
forwarding webkit. It's said webkit is much faster

Hi Ryan,

Unfortunately WebKit does not provide something similar to JavaXPCOM.
I agree that JavaXPCOM provided very useful functionality, and was the
main push for porting the Browser's mozilla implementation from its
original Linux-only form to also run on Windows and OS X as of
eclipse/swt 3.3.  The motivation for switching to use WebKitGTK+
whenever possible for SWT.NONE-style Browsers as of eclipse/swt 3.7 is
for the interface and functional stability that it will bring.
Mozilla's new policy of zero frozen interfaces reinforces this change
even more strongly going forward.

That being said, the example you mention brings up an interesting
point.  Although JavaXPCOM is out of the picture as of xulrunner 2.0,
at least some functionality that JavaXPCOM enabled can be done in JS
instead.  For example, the headers observer could be implemented with:

String string =
   "var httpRequestObserver = {observe: function(subject, topic, data)
{alert('called!');}};" +
   "var observerService =
Components.classes[\"@mozilla.org/observer-service;1\"].getService(Components.interfaces.nsIObserverService);"
+
   "observerService.addObserver(httpRequestObserver,
\"http-on-modify-request\", false);" +
   "observerService.addObserver(httpRequestObserver,
\"http-on-examine-request\", false);";
browser.execute(string);

This has me wondering if there could be value in continuing to work
with xulrunner versions >= 2.0 (SWT.MOZILLA-style Browsers only).
This is not a 3.7 plan item, but I've created a feature request to
investigate this, time permitting (
https://bugs.eclipse.org/bugs/show_bug.cgi?id=327696 ).  I don't think
this is critical at this time because as I previously said, support
will be continued for JavaXPCOM users for xulrunner < 2.0.  However as
time passes it may become desirable for some clients to use JS instead
if they can realize the benefits of xulrunner >= 2.0 in return.
