Try adding the DSL before the DSLR:
<resource source='classpath:test/rules/testing.dsl' type='DSL'
/>
<resource source='classpath:test/rules/test.drl' type='DSLR' />

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' >
<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
