[rules-users] Drools examples don't run

[Bruno Freudensprung]

Hello,

I think you have to add the xstream jar to your classpath.
Here is the Maven dependency :

    <dependency>
      <groupId>com.thoughtworks.xstream</groupId>
      <artifactId>xstream</artifactId>
      <version>1.3.1</version>
    </dependency>

Best regards,

Bruno.
