[news.eclipse.birt] Re: Using Viewer In RCP

[Jason Weathersby <jasonweathersby@xxxxxxxxxx>]

Anup,

I believe this is a problem with the classloader.  You may be able to do 
this by adding a JSP page to the viewer plugin that sets the 
PARENT_CLASSLOADER key
http://wiki.eclipse.org/Adding_an_Object_to_the_Application_Context_for_the_Viewer_%28BIRT%29

or

BEFORE calling the WebViewer.display () method, call the 
WebappAccessor.start () method, as shown here:

WebappAccessor.start (
ViewerPlugin.WEBAPP_CONTEXT,
YourPlugin.PLUGIN_ID,
Path.EMPTY
);

You will see yourplugin.PLUGIN_Id will cause the viewer to use your 
plugins classloader.  You will have to copy the BIRT directory of the 
viewer into your application though, so the first solution may suit you 
better.
