[rules-users] BRMS Insurance Sample - Invalid Class Exception

Folks, Using BRMS 4.0.2 and examples 4.02 as downloaded from the 'official release' site. Working my way through the Drools Insurance Sample (on BRMS). I'm deploying BRMS successfully on JBoss 4.2.1 with Java 1.6.0_02. I can import the repository_export.xml ok and see the files. I leave this part of the sample running as per the instructions. When I go to the 2nd part of the example I have a problem running the unit tests: within /drools-examples/drools-insurance I run: mvn clean package. I get the error(1) at the bottom of this email. I do *not* get the output as per the documentaiton. I skip the tests, build and deploy the drools-insurance.war When deploying the war I see the following error (2) in the JBoss logs . However main drools insurance page loads ok as per the screenshot in the documentation): 22:43:13,576 INFO [WebappClassLoader] validateJarFile(C:\software\jboss-4-2-1\server\default\.\tmp\deploy\tmp26632drool s-insurance-exp.war\WEB-INF\lib\servlet-api-2.3.jar) - jar not loaded. See Servlet Spec 2.3, section 9.7.2. Offending class: javax/servlet/Servlet.class I enter some values in the web app (make sure there are no nulls) press 'continue' then get the same error (3) 22:48:55,294 ERROR [STDERR] java.io.InvalidClassException: org.mvel.AbstractParser; local class incompatible: stream cla ssdesc serialVersionUID = 256028721591955695, local class serialVersionUID = -7464517220700761297 22:48:55,310 ERROR [STDERR] at java.io.ObjectStreamClass.initNonProxy(ObjectStreamClass.java:562) As an aside , when I look for the latest BRMS , as mentioned in the docs (http://cruisecontrol.jboss.com/cc/artifacts/jboss-rules) - I get a 'Invalid File or Directory' Is there anything I should try to resolve this?
