Re: [rules-users] Eval0Invoker : java.lang.NullPointerException

Hi, I am new to Drools and I have read about it and not mastered yet. I have written some rules and junit to test it. The rules works good and passes the test if ran individually, but if ranned all at once with one junit test case with all the test cases in it, it is through this exception. Please find the stack trace. com.ge.energy.drms.smartgrid.datamodel.services.enddevicemanagement.pandeviceregistrationservice.PANDeviceRegistrationServiceFault: com.ge.energy.drms.external.integration.service.impl.Rule_PAN_Device_Smart_Device_Model_Device_Class_null_ruleEval0Invoker@1e87bc80 : java.lang.NullPointerException at com.ge.energy.drms.external.integration.service.impl.PANDeviceRegistrationServiceImpl.provisionPANDevice(PANDeviceRegistrationServiceImpl.java:108) at com.ge.energy.drms.external.integration.service.impl.test.ProvisionPanDeviceRequestValidationTest.testMACAdress(ProvisionPanDeviceRequestValidationTest.java:249) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) at java.lang.reflect.Method.invoke(Method.java:597) at junit.framework.TestCase.runTest(TestCase.java:168) at junit.framework.TestCase.runBare(TestCase.java:134) at junit.framework.TestResult$1.protect(TestResult.java:110) at junit.framework.TestResult.runProtected(TestResult.java:128) at junit.framework.TestResult.run(TestResult.java:113) at junit.framework.TestCase.run(TestCase.java:124) at junit.framework.TestSuite.runTest(TestSuite.java:232) at junit.framework.TestSuite.run(TestSuite.java:227) at org.junit.internal.runners.JUnit38ClassRunner.run(JUnit38ClassRunner.java:83) at org.eclipse.jdt.internal.junit4.runner.JUnit4TestReference.run(JUnit4TestReference.java:49) at org.eclipse.jdt.internal.junit.runner.TestExecution.run(TestExecution.java:38) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:467) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.runTests(RemoteTestRunner.java:683) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.run(RemoteTestRunner.java:390) at org.eclipse.jdt.internal.junit.runner.RemoteTestRunner.main(RemoteTestRunner.java:197) com.ge.energy.drms.external.integration.service.impl.Rule_PAN_Device_Smart_Device_Model_Device_Class_null_ruleEval0Invoker@1e87bc80 : java.lang.NullPointerException I have googled on this and found that, it might not be able to take all the rules, one by one, and execute it. As I said I am new to Drools, I am not able to work on this. Please help me on this.
