[rules-users] Reading a Guvnor PKG from drools API
Hey,
I was trying to read a package(ResourceType.PKG), which i downloaded from
Guvnor, using KnowledgeBuilder, but I consistently get the following error
while trying to access the file.
Here's my code and the error,
**Code**
KnowledgeBuilder kbuilder = KnowledgeBuilderFactory.newKnowledgeBuilder();
kbuilder.add( ResourceFactory.newClassPathResource( "Goal Creation
Charges.pkg", getClass() ), ResourceType.PKG );
if ( kbuilder.hasErrors() ) {
System.err.println( kbuilder.getErrors().toString() );
}
kbase = KnowledgeBaseFactory.newKnowledgeBase();
kbase.addKnowledgePackages( kbuilder.getKnowledgePackages() );
**Error**

I have tried using both binary and source from guvnor, but neither of them
works. I get the same error. Is there something m doing wrong ?
Thanks,
Abhinay
