6:21 a.m.
I'm still having problem unfortunately.. :(
i get a strange error that i didn't got before turning to maven:
when running:
*kbuilder.add(ResourceFactory.newClassPathResource("src/main/rules/sample.drl"),
ResourceType.DRL);*
this errors occurs:
java.lang.RuntimeException: java.io.FileNotFoundException:
'src/main/rules/sample.drl' cannot be opened because it does not exist
at
org.drools.compiler.PackageBuilder.addKnowledgeResource(PackageBuilder.java:559)

... 3 more
i see a difference between the .classpth and .project files in both projects
(Drools project vs Maven Project).
could this be the reason?

OK, the eclipse maven plugin added those deps type as 'pom'
instead of
'jar',
so the drools jars weren't included.
fixed that.
thanks.
