[rules-users] Drools 5 - Not sure why this simple DSL not working

[Vijay K Pandey]

Thanks, but I have gone through this before and I don't see any issue in the DRL & DSL file I wrote. Also within the eclipse plug-in, "Rete View" comes up fine for the DRL but while running as java application, "Unable to expand:" error comes.

Hi,



I am trying to get a very simple DSL working but all the time it gives the error of Unable to expand: If I take the DSL away everything runs fine, not sure whats going on.



So what I did is strip away all other stuff and just added a plain simple DSL -- but still the same error



Unable to expand:             LOGGING



DSLR file Contents:



package test.rules

dialect "mvel"



expander testing.dsl



rule "TestingCheck"



      when

      then

            LOGGING

end



DSL file content

[consequence][]LOGGING=System.out.println("hello");



ChangeSet XML file (test_changeset.xml)

<change-set xmlns='http://drools.org/drools-5.0/change-set'

             xmlns:xs='http://www.w3.org/2001/XMLSchema-instance'

             xs:schemaLocation='http://drools.org/drools-5.0/change-set drools-change-set-5.0.xsd<http://drools.org/drools-5.0/change-set%0Adrools-change-set-5.0.xsd>' >

   <add>

       <resource source='classpath:test/rules/test.drl' type='DSLR' />

       <resource source='classpath:test/rules/testing.dsl' type='DSL' />

   </add>

</change-set>



I am loading the changeset set via



KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();

kbuilder.add(ResourceFactory.newClassPathResource("test_changeset.xml"), ResourceType.CHANGE_SET);



Any hint what is going wrong?



Thanks

Vijay
