[Mauricio Salatino]

*java.lang.IllegalArgumentException: Unknown process ID: Number Guess


*That exceptions means that you probably don't add the process definition to
the current knowledgeBuilder.
To see these kind of problems you probably need to add something like this
after KnowledgeBuilder add calls:

if ( kbuilder.hasErrors() ) {
    System.err.println( builder.getErrors().toString() );
}
