Looks like you need to update your Java version on the server - red power isn't loading and when CC is trying to check if redpower is loaded its getting the error message.

it´s not the Newest Update from Java?


root@euve3745:~# sudo java -version
java version "1.6.0_20"
OpenJDK Runtime Environment (IcedTea6 1.9.13) (6b20-1.9.13-0ubuntu1~10.04.1)
OpenJDK 64-Bit Server VM (build 19.0-b09, mixed mode)

No. It seems like redpower requires Java version 7 - go to their site and download it.

or simply type apt-get install java-7-openjdk

hi,
Thank you both Unfortunately,
this does not work with "apt-get" there I had already tried I get the following message

root@euve3745:~# apt-get install java-7-openjdk
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Couldn't find package java-7-openjdk
root@euve3745:~#

I had it on this page Try http://alexander.holbreich.org/2011/11/java-7-on-debian/ However, I get this error there looking not so slow on I ^ ^ http://pastebin.com/ey305WSw

I'm not trying to be awful here, but Java installation is way beyond the scope of this forum - and CC works fine with Java 1.6, its RedPower that doesn't.
