Hello Paul,
First of all, we are working on a solution to a problem in this area where the binding calls to odaPassword, odaUser, odaURL and odaDriverClass are made in different orders and people end up seeing a dbparams undefined error. The quick, crude, fix to this for now is to add:
var dbparams = new GetDbParams("C:/Program Files/KonaKart/webapps/konakartadmin/WEB-INF/classes/konakartadmin.properties");
... in front of each of the 4 dbparams references. This isn't very efficient and means you have to declare the filename in 4 places, so we will look for a neater solution for the next release.
To your main question:
The jar you want in your classpath is called konakartadmin_reports.jar - you'll find it in /webapps/birt-viewer/WEB-INF/lib
Regards,
John
