spampana / drools Goto Github PK

Hi colleagues, i have just started working with Drools on Net beans. I am having challenges when invoking the drl file in code , for instance in Main.java , when i compile the code i am getting this error continuously.

Exception in thread "main" java.lang.NullPointerException
at DroolsTest.Main.initialiseDrools(Main.java:74)
at DroolsTest.Main.main(Main.java:58)

The following code snippet might give you a hint:

42 private static final String DRL_FILE = "/DroolsTest/testrules.drl";

public static void main(String[] args) {
58 initialiseDrools();

}

try {
Reader reader;

74 reader = new InputStreamReader(Main.class.getResourceAsStream(DRL_FILE));

pbuilder.addPackageFromDrl(reader);
}
