Unhandled event loop exception "Unknown Mozilla path" with Eclipse 3.7.1

Question

I installed the Tizen SDK 2.0 which uses Eclipse 3.7.1 as an IDE on Ubuntu 12.10 64bit. When trying to create a Tizen Web Project I got the following error message from Eclipse:

Unhandled event loop exception No more handles [Unknown Mozilla path (MOZILLA_FIVE_HOME not set)]

The problem is that Eclipse is configured to use Xulrunner as a headless browser inside the IDE. Xulrunner is not in the repositories for Ubuntu 12.10 any more, therefore Eclipse is not able to find the libraries.

Answer 1

The current Tizen IDE is based on Eclipse 3.7.1, and Eclipse SWT faq page page lists the required Xulrunner versions for Eclipse:

Eclipse 3.7.x/4.1.x: Mozilla 1.4 GTK2 - 1.7.x GTK2, XULRunner 1.8.x - 1.9.x and 3.6.x (but not 2.x), WebKitGTK+ 1.2.x and newer

There are two solutions to this problem:

1. Manually install XULRunner and install it
2. Configure Eclipse to use Webkit instead of XULRunner

Manual installation of XULRunner
A compatible version of - XULRunner 3.6.x - can be downloaded from Mozilla's ftp server at http://ftp.mozilla.org/pub/mozilla.org/xulrunner/releases/3.6.28/runtimes/

Extract the xulrunner folder into your home directory, e.g. /home/username/opt/xulrunner.

Configure Eclipse to look for XULRunner in that folder by adding the following line to the tizen-sdk/ide/eclipse.ini file:

-Dorg.eclipse.swt.browser.XULRunnerPath=/home/raju/opt/xulrunner

Restart Eclipse and everything should work as expected.

Use Webkit instead of XULRunner
Install the package libwebkitgtk-1.0-0 and configured Eclipse / TizenIDE to use Webkit instead of Xulrunner by adding this line to the eclipse.ini:

-Dorg.eclipse.swt.browser.DefaultType=webkit

Restart Eclipse and you are ready to code.
