Hi Arthur, You're correct in assuming that there is an invisible instance of hosted mode running when running GWTTestCase on a continuous build system.
The solution is indeed to run the process with an Xvfb instance, as Manuel suggested. It's possible that the reason you're setup still isn't working is because of some missing configurations for the Xvfb instance to be able to run the tests properly. For example, you may want to double check that the DISPLAY environment variable has been set to 0:0, and if not, export it so that it is set appropriately on the next run of unit tests. Hope that helps, -Sumit Chandel On Fri, Oct 17, 2008 at 10:52 AM, Arthur Kalmenson <[EMAIL PROTECTED]>wrote: > Thanks for the reply.
