Security issue (Sharepoint)

[fkeller]

Hi,

 I am developing web parts for Sharepoint 3.0. When I shutdown the PSS Service, my chart are rendered, but when I start the PSS Service, then the chart image is no more rendered. When I check at the source <img> and try to access directly via the URL to the chart image I get a Security Exception...

 Since I am in Sharepoint my pages use the Windows Authentification method (Single sign-on).

How can I configure Chart FX and PSS ?

 
Thanky for your answers.

You are going to need to disable PSS in SharePoint. The following KB article shows you how to do this:
