Hi,
I have been trying to write the following code to automatically deploy any
changes made to the rules. However i am getting nullpointerexception errors.
I see many posts regarding this topic and have tried different options but
the error won;t go away.
public static void main(String[] args) {
try {
FileInputStream file = new
FileInputStream("C:\\Users\\folderabc\\workspace\\Drools
Sample\\bin\\Guvnor.properties");
Properties p = new Properties();
p.load(file);
RuleAgent agent = RuleAgent.newRuleAgent(p); *<-- this is where
it is failing* RuleBase rb = agent.getRuleBase();
WorkingMemory ksession = rb.newStatefulSession();
Car c = new Car("yellow", 2100);
Driver d = new Driver("Isha", 18, c, "lets try it" );
ksession.insert(d);
ksession.fireAllRules();
//logger.close();
} catch (Throwable t) {
t.printStackTrace();
}
}
/Here are the errors i am getting on my console:/
java.lang.NullPointerException
at org.drools.agent.RuleAgent.refreshRuleBase(RuleAgent.java:384)
at org.drools.agent.RuleAgent.configure(RuleAgent.java:368)
at org.drools.agent.RuleAgent.init(RuleAgent.java:268)
at org.drools.agent.RuleAgent.newRuleAgent(RuleAgent.java:208)
at org.drools.agent.RuleAgent.newRuleAgent(RuleAgent.java:168)
at kijanowski.GuvnorTest.main(GuvnorTest.java:43)
Any help will be greatly appreciated. Thank you
