Getting Null Pointer Exception while calling Droole rules

[praveen...@gmail.com]

hi team,

i developed one rule using declarative model.Now i need to use that rule in java code.I developed standard alone java project.Have alook at my code.

package anil.com;

import org.drools.RuleBase;

import org.drools.WorkingMemory;

import org.drools.agent.RuleAgent;

import org.drools.definition.type.FactType;

public class DroolGuvnor {

public static void main(String[] args) throws InstantiationException,IllegalAccessException{

RuleAgent ruleAgent = RuleAgent.newRuleAgent("/Guvnor.properties");

RuleBase  ruleBase = ruleAgent.getRuleBase();

FactType  factType = ruleBase.getFactType("anil.com.Number");

Object obj = factType.newInstance();

factType.set(obj, "numberone", 2);

factType.set(obj, "numbertwo", 2);

WorkingMemory workingMemory =  ruleBase.newStatefulSession();

workingMemory.insert(obj);

workingMemory.fireAllRules();

System.out.println(factType.get(obj, "message"));

}

properties file:

Guvnor.properties

url=http://localhost:8080/guvnor/org.drools.guvnor.Guvnor/package/anil.com/newsnap

enableBasicAuthentication=true

username=admin

password=admin

name=kitesystems

Now when i run my java class i am getting following exception.

Exception in thread "main" java.lang.NullPointerException

at java.util.Properties$LineReader.readLine(Unknown Source)

at java.util.Properties.load0(Unknown Source)

at java.util.Properties.load(Unknown Source)

at org.drools.agent.RuleAgent.newRuleAgent(RuleAgent.java:273)
