GWT + Flash + Ubuntu

I've been trying to use Flash components in a GWT project running under Ubuntu, and I've been having a devil of a time getting flash to work. Flash works fine in my Firefox install, but not in the GWT hosted-mode browser. I've just found a fix, so here it is for Google & the world to find:

The trick is simply to copy¹ the flash plugin that Firefox is (successfully) using to the right directory, so that GWT can find it.

  # Find the plugin
  $ locate libflashplayer.so
  /usr/lib/flashplugin-installer/libflashplayer.so

  # Find the Mozilla directory.
  $ find $ECLIPSE_HOME/plugins -type d -name 'mozilla*'
  /home/kris/eclipse/plugins/com.google.gwt.eclipse.sdkbundle.linux_1.6.4.v200904062334/gwt-linux-1.6.4/mozilla-1.7.12/

  # Copy the plugin to the mozilla-1.7.12/plugins directory.
  cp /usr/lib... /home/../mozilla-1.7.12/plugins/

Restart the GWT hosted mode task, and Bob should be your uncle.

¹ Or symlink, or a bit of mucking about with LD_LIBRARY_PATH would probably do it too, but I'm just going for a straight copy here.
