<p>Can you explain more about the setup of your application? I've not seen this error before?</p>

<p>Hi Michael,</p><p> </p><p>I'm developing against the eclipse IDE, so I defined a target platform with all the needed plugins including Birt.</p><p>If I run the new eclipse application (including Birt), everything seems working (I can make a new report, edit it and so on), except for the report preview function. Trying to use it, gave me the mentioned Exception.</p><p> </p><p>[color=rgb(0,0,0);font-family:Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif;font-size:13.63636302947998px;]By now, I fixed it. I'm not sure how. By intuition I just added the [/color]<strong><em>jetty</em></strong>[color=rgb(0,0,0);font-family:Arial, 'Liberation Sans', 'DejaVu Sans', sans-serif;font-size:13.63636302947998px;] plugin to my target-platform (dependencies). This was enough to fix this opaque exception. The Birt Preview is no fully functional.[/color]</p><p> </p><p>best regards,</p><p>Said</p>
