I do not see the icon to configure GreenPepper

The icon is only available if you have administration right.

I got a NoSuchMethodError error :

If you have this error :

java.lang.NoSuchMethodError: org.picocontainer.MutablePicoContainer.addComponent(Ljava/lang/Object;)Lorg/picocontainer/MutablePicoContainer;
        	at org.codehaus.waffle.context.pico.PicoComponentRegistry.<init>(PicoComponentRegistry.java:75)
        	at org.codehaus.waffle.context.pico.PicoWaffleContextListener.buildComponentRegistry(PicoWaffleContextListener.java:19)

                ...

You need to remove the file WEB-INF/lib/picocontainer-1.2.jar. We already have a newer version of PicoContainer in the GreenPepper plugin and it is compatible with version 1.2. Most of the time, both can co-exist but sometimes, class loader issue will throw this type of error.
