Dear Drools community:Being new to rule-based systems, I've read some introductory materials on this paradigm's concepts where I was led to some rule engine Java implementations, your product seeming the most interesting to me at the moment. Concerning RBMSs, in general, and Drools, in particular

All,
The MBeans in Drools where designed to be used out of the box, so no
facilities where implemented to make it easier to re-implement them (of
course you can do that, just saying, try out of the box first and see if it
matches your needs or not... :) ).
To enable the mbeans:

Did you make a backup of Guvnor's repository *before* the upgrade? It seems
to me that it was corrupted (or at least updated) by Guvnor 5.1.1.

You could use Drools-Verifier to check things like Range Validation, Missing
equality, Redundancy, etc.
Here you have some kind of documentation:

would update it some time ago...)

Hello Laun,
Thanks for the reply.
Well there is nothing wrong with the listeners. The requirement is such that
we need all the information only after firing the rules. The
KnowledgeSession itself should provide all the information rather than going
through each and every events and logging the i

Valid point, but you can't move JDKs if it is not supported by the
application server.
Main platform over here is Oracle.10g, i.e. JDK5.

All who stick with JDK 1.5 should realize that
- JDK 1.5 has officially reached "end-of-life", i.e., no more maintenance
- JDK 1.6 has a far better optimized JVM
There is no good reason to stay on JDK 1.5 - once you have left JDK 1.4 ;-)

Your can use the various EventListeners like ProcessEventListener to
collect statistics about rule execution while your tests are executing.

I am now using Cobertura to evaluate the test coverage on my Java
application.
However, Drools rules are not counted by Cobertura, because classes for
rules are dynamically created and therefore not instrumented by Cobertura
for static analysis.
How can we automatically analyze the test coverage

Thank you for so much explanation on the internal. I will ask more on the

Hi Mark,
these last 2 years I worked for 2 major european banks and a well-known
international phone directory company.
All these clients are still using the JDK 5.
So IMHO, it is not a good idea ;-)
Furthermore the added value of the JDK6 against JDK5 sounds limited to me
(Stax maybe..)

Thanks for the options, Bruno and Wolfgang.
But is there a more 'generic' way to do the matches ? The problem I have is
that the # of instances that might match could vary. And I have to provide a
means for the business users to be able to provide that 'option's code'
using a decision table. Bas
There is an implementation of the interface
KnowledgeSessionMonitoringMBean,see
./drools-core/src/main/java/org/drools/management/KnowledgeSessionMonitoring.java.
Looking at this implementation will show you that the information
about firing rules, fact operations is collected by the object acting
