Hi,
I am using NetDiagram version 3.1.1 in asp page which contains OverviewApplet / DiagramApplet / ShapeListBoxApplet object, data can be shown normally without using membership 2.0 in ASP.NET, however I got errors below when using control in authenticated folder.


error:

I found the similar problem http://mindfusion.eu/Forum/YaBB.pl?board=netdg_disc;action=display;num=119304781...

I am not sure is it better to put jar file out of authenticated folder.

Is there any suggestion?

Many thanks
