Answer 1

When I got this I checked:
<class>package.name.DaoClass</class>
was defined in persistence.xml, this resolved the error. Also check
<property name="kundera.annotations.scan.package" value="package.name"/>
matches correctly to your package name.

Answer 2

"kundega.rules.Rule" package name is correct? Or is it "kundera.rules.Rule" ?
