Not able to load Drools through knowledgeBase/ksession

[niteshjain132]

does anyone know why sample drools project is working when run via main() Method ,

and when invoked via camel processor, i'm getting the following error wile trying to create the knowledge base (KnowledgeBase kbase = kbuilder.newKnowledgeBase();)

Any idea why the KnowledgeBuilderImpl   not able to load message class(Message class is a static class).

Hi

Can you point us in the direction where you found this sample project, and also what versions of products you are using? Are you use JBoss Fuse, or something else?

[niteshjain132]

yes, i'm using JBoss Developer studio, where there an option to create a "Sample Drool Project" (under New > Drools Project).

Jboss Fuse 6.0 is the Server

and now it works fine when changed the Drools version from 6.0.0.Final to 6.1.3.Beta3, had wrong version of drool in pom.xml

<dependency>

  <groupId>org.drools</groupId>

  <artifactId>drools-core</artifactId>

  <version>6.1.0.Beta3</version>

</dependency>

Thanks,

Nitesh
