thanks edson
your hints helped me search in the right direction.
i resolved the problem although i do not know what
exactly was the problem..
i did have this antlr dependency in my pom:
<dependency>
<groupId>org.antlr</groupId>
<artifactId>antlr-runtime</artifactId>
<version>3.1.1</version>
</dependency>
<dependency>
<groupId>org.antlr</groupId>
<artifactId>antlr</artifactId>
<version>3.1.1</version>
</dependency>
which is the same dependency drools uses.
when i removed these two dependencies from my pom
everything worked.
anyway: it works, i am happy! thanks, tim

You need antlr-runtime jar in your classpath, although maven should get
it as a transitive dependency.
Try running:
mvn help:effective-pom
That will show you what maven is using as pom after resolving
dependencies. If antlr-runtime jar is not there or if you have the wrong
version, that would be the problem.
