error Esper XML dom document

I have problems with Esper framework. After searching for a solution, I found an example from official website:

http://esper.codehaus.org/esper-4.11.0/doc/reference/en-US/html/examples.html#examples-autoid

The source code of this example can be found here: http://esper.codehaus.org/esper/download/download.html in the examples\autoid dir.

When I run this example I get the following error. Any help will be appreciated.
