I'm under ubuntu 11.04 and I'm trying to run GWT on it via eclipse but
when i go to the code design I get this:
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.
I tryed everything to solve this with no success. Is there any way to
easily fix this? By the way I can't install the eRCP eclipse's plugin.
When I try to install I get this:
Cannot complete the install because some dependencies are not
org.eclipse.wb.ercp.feature.feature.group [0.9.0.r36x201105051047]
cannot be installed in this environment because its filter is not
Please help me, thank you.

Hi, I had the same problem. I fix it as follows:
1) install xulrunner-1.9.2 (the version i've installed is
2) start eclipse using this command: eclipse -vmargs -
Dorg.eclipse.swt.browser.XULRunnerPath=/usr/lib/xulrunner-1.9.2 (use
the exact path to the lib)

Hope this help.

The eRCP Designer plugin is Windows only.

I know this is about a year old, but I am getting the same error in Indigo. My platform is slackware. I don't have xulrunner installed as a package separate from firefox et al.

I was wondering a few things,

1. Which version of xulrunner should I install for Indigo,
2. I thought eclipse was cross-platform, and (at least as of Indigo) eRCP is a core package. If it is indeed MS Windows (versions?) only, is there a list of at least core packages online somewhere that aren't really cross-platform?

The rest of the problems (org.eclipse.wb.ercp being an id that doesn't show up at all in the package list in the "install software" wizard and only shows up in error messages, suggesting linking to a compatible xulrunner, org.eclipse.wb.ercp appearing to be a WindowBuilder subclass, et al) are things I should take up with eclipse on their mailing list, but if anyone is still reading this and could clarify these two things it would be appreciated.
