Could not load "Polls for Confluence" plugin

[Björn Hempel]

Hello,

we have a problem installing the "Polls for Confluence" plugin.

The error message is as following: "The Addon could not load. It has one or more failures which prevent activation."(translation from German)

Confluence version: 5.3.4

Polls version: 1.3.1 (also tried 1.3.2)

Thanks for your help!

SOLUTION: We have installed Tomcat7. Now we installed Tomcat6 and it works.
