I am seeing the same issue. My configuration is slightly different in
that I am using Drools 4.0.3 and JBoss 4.2.2GA with Java 5. I have been
searching very hard to find where these two different version of
AbstractParser are coming from. This class comes out of the MVEL. The
jar in the drools-jbrms is mvel14-1.2.10.jar. I only see this jar
within the deployment.
My thought is that a serialized version of the class is stored in a file
somewhere in the demo project or the BRMS itself, and that it is from an
older version mvel.

--Original Message-
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\tmp2

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:

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?
