SWT Browser requires a compatible xulrunner version installed

SWT Browser requires a compatible xulrunner version installed

error:

GWT Designer uses the SWT Browser widget to render the GWT UI. SWT
Browser requires a compatible xulrunner version installed: it should
be 1.9.1.x or 1.9.2.x version and meet the current environment
architecture. See http://www.eclipse.org/swt/faq.php#whatisbrowser and
related topics for more information. 

solution:

1 - Download eclipse from eclipse.org. 

http://www.eclipse.org/downloads/packages/eclipse-classic-372/indigosr2
(DO NOT USE UBUNTU REPOSITORY.)

Install GWT according to the guide:
https://developers.google.com/eclipse/docs/download

2 - After installation, start Eclipse and disable the option

 "Use webkit rendering window for GWT UI if available", at Window, Preferences, Window Builder,

 GWT

3 - Install the following two libraries in the following order, which will replace the webkit: 
sudo dpkg-i packagename.deb

download and install:
https://docs.google.com/file/d/0B9KWSpNWygKAYW1yeDhBa2xaRlU/edit# 

(filename: libhunspell-1.2-0_1.2.11-1ubuntu1_i386.deb ) 

download and install:

(filename:  xulrunner-1.9.2-ubuntu-i386.deb )

 Or look for xulrunner!

4 - Restart eclipse. GWT Designer is already running again.
