   Inbox

Hi,

I‘m trying to work the decision table supported by Drools.
I can run the supplied example in drools-example successfully.

But, if I try to create my own application package and run it, I‘m getting the
following error :

-----------------------------------------------------------------
(null: 1, 292): cvc-elt.1: Cannot find the declaration of element ‘rule-set‘.

Would appreciate if anyone can help me out.

Thanks.

Off the top of my head, this looks like your classpath is missing one of the
Drools JARs when running LimitManagement‘s main(). The ‘import‘ declaration
should be part of drools-base.jar, IIRC.

Thanks for your mail,Geoffrey.
Actually, I have figured out the problem.
The ‘rules.xsd‘ file was not present in the META-INF folder.

Cheers.

It should be present in the META-INF of drools-base.jar; are you adding it
explicitly to your own application?

Yes. Otherwise, I‘m getting that error.
