gcjwebplugin is dead, it should have been removed, but nobody has done that.
Just don't enable it in configure.

Well then what replaces the Firefox plugin functionality - ie.
what happens when I include '--enable-browser-plugin' in configure args ?
A JVM environment and Java SDK is hardly worthy of the name unless it
can be used to run java applets embedded in webpages from the system
browser - how else is one meant to do this using only GCJ components ?

This problem appears to be the ONLY reason gcjwebplugin fails to build ;
are you sure rumors of its demise are not premature ?

It is what the gcjwebplugin authors told me when I reported it to them many
months ago.  The plugin is maintained as part of icedtea for openjdk, and
that's where development and maintainance occurs.

gcjwebplugin in gcj/Classpath is dead.  I actually suggested it be removed some
time ago, but there was resistance to doing so.  Current development on a Free
Software browser plugin takes place in the IcedTea-Web project, but this
currently supports only IcedTea as the JDK.  I'd like to see it eventually
support gcj too, but it would need work on both sides for this to happen.

As to your comment about a JDK being irrelevant without applet support, I think
most enterprise JDK users would take issue with this; there is plenty of use
for a JDK besides running applets.  OpenJDK itself (as provided by Oracle)
doesn't have applet support, hence the need for the IcedTea-Web project to
provide a Free implementation.

BTW, regarding the subject, isn't xulrunner 2.0 firefox 4.0, not 3.6?

IMHO, also hence the need to maintain gappletbrowser + gcjwebplugin in the
interim .  Why must I install yet another whole subsystem just to get 
a java applet displaying in my browser with GCJ + libjava, when it
used not to require one ?  
If gappletbrowser + gcjwebplugin is so thoroughly deprecated, then
gcc's configure should refuse to accept the '--enable-browser-plugin'
option, or, if it does accept it, something like the patch attached
to this bug must be applied to enable the browser plugin to compile.

Yes, I am building against firefox-4.0 / xulrunner-2.0 but the same problem 
will occur if user try to '--enable-browser-plugin' against firefox-3.6 SDK,
because as Comment #2 shows, they removed the nsIPluginTagInfo2 interface
in firefux-3.6 .
