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.

and imported the example projects to my eclipse workspace but the
examples run with error.
The two example projects are namely drools-examples-drl
& drools-examples-fusion.

Does anyone experience the similar issues and know how to fix that?
