Hi,

I have set all the jars file in the classpath, but still m getting the
same exception.
The exception is caused by : Null pointer exception.
I am not able to understand why it is giving me this exception, while in
the mailing list I didn't found anybody having this
exception, everyone else I found has 'Class Not found Exception'.

 
This is my code snippet :

KnowledgeBuilderConfiguration config =  KnowledgeBuilderFactory.
newKnowledgeBuilderConfiguration();
config.setProperty("drools.dialect.java.compiler", "ECLIPSE");
KnowledgeBuilder kbuilder =KnowledgeBuilderFactory.newKnowledgeBuilder(
config );

       //KnowledgeBuilder kbuilder =
KnowledgeBuilderFactory.newKnowledgeBuilder();
       kbuilder.add(ResourceFactory.newClassPathResource(
"shopingdiscount.drl"), ResourceType.DRL);



This is my exception:
Drools config: unable to use the drools.compiler property. Using default. It was set to:0
org.drools.RuntimeDroolsException: Unable to load dialect 'org.drools.rule.builder.dialect.java.JavaDialectConfiguration:jav

Am I missing anything that is to initialized , so that I can get through
this Null Pointer Exception.
