Why do i get this error?The class exists, it is a default class of the activiti-engine-examples and is described in the user guide.

thanks a lot for help

The "<extensionElements>" should come before any other elements. So you should place it before the humanPerformer element.

Next time, paste the xml in a "code" block, so it more clear to the other users trying to read it.
