When making the call:

WebViewer.display(path, WebViewer.HTML, browser, "run");

I get the following:

I am using Eclipse RCP and have the core runtime plugin (which contains CoreException.class) installed. Any help is greatly appreciated.

Do you have the birt framework plugins in your launch configuration? It
looks like it is not finding org.eclipse.core.runtime plugin.
