Hi,

I'm trying to use the BIRT WebViewer in an Eclipse 4.2.1 RCP. So It seems pretty easy to use, but it doesn't work, anyway. I use WebViewer.display(path, browser, map));. Where map is the map from the post: http://www.eclipse.org/forums/index.php/m/834817/?srch=WebViewer#msg_834817
It always ends up in:

Furthermore the WebViewer opens and shows another error message, if I click on "show exception stack trace":

The .rptdesign file is just a dummy file that contains nothing but a label (no data sources).
What do I have to do, to make the WebViewer work?

Best regards

Are you getting this error when launching through a debug configuration? I just tested that code in my 4.2.1 env and it worked.

Hi Jason,

that was a stupid mistake by myself: I just forgot to add a plugin to the manifest. Actually this was quite obvious... sorry for this false alarm.

Best regards
Bastian
