Problems running headless under Xvnc [message #539698]

I have SWTBot tests that run fine headless on my F-12 system. I have the same tests set up to run in a Hudson instance under Xvnc on another machine (there is an exec that sets up everything). The tests fail; often right off the start in my beforeClass method. I am getting a missing widget when I try to access the Window->Preferences menu.

There are some screenshots that I got and in them, the main Eclipse window was not shown to be active (i.e. the title bar was grey). Is it possible that this is the cause of my problems?

The following is the start of my beforeClass method:

	public static void beforeClass() throws Exception {
		SWTBotPreferences.KEYBOARD_LAYOUT = "EN_US";
		bot = new SWTWorkbenchBot();
		// Close the Welcome view if it exists
		try {
		bot.viewByTitle("Welcome").close();
		} catch (Exception e) {
			// do nothing
		}
		bot.menu("Window").menu("Preferences").click();

The widget not found is generated for the last line above.

Is there something I must do to ensure that the main Eclipse window is in focus?

I should mention that I am using SWTBot 568-e36 and Eclipse Helios RC4. The same set of tests runs under Hudson with Galileo and a previous version of SWTBot.

A simple way to verify the VNC setup is if the failure screenshots
contain windows with titlebars. If the failure screenshots don't contain
a titlebar then there's something wrong with your setup.

Could you verify that your setup is as described here ?

Thanks for the pointer, it is good to know.

I found the problem. My script for Galileo doesn't work for Helios under XVnc, though it manages to work on my local system being run from the command line. I found that Eclipse can't find the SWTBot headless application, though the proper plugin is in the plugins folder. This is due to me using plugins rather than dropins. I guess it sort of works sometimes when in the plugins folder. Switching to using the dropins folder turned out to be the way to go.
