        PackageBuilderConfiguration conf=new PackageBuilderConfiguration();

        conf.setCompiler(PackageBuilderConfiguration.JANINO);

    

        //Building package builder with defined configuration

        final PackageBuilder builder=new PackageBuilder(conf);

        //Class ab=null;

        

        try

        {

            //FileInputStream fs=new
FileInputStream("C:\\jdevstudio10133\\jdev\\mywork\\ServletApplication\\Proj
ect1\\src\\project1\\Test.drl");

            //ab=Class.forName("project1.RuleTest2");

            //builder.addPackageFromDrl(new
InputStreamReader(ab.getResourceAsStream("Test.drl")));

            

            builder.addPackageFromDrl(new
InputStreamReader(getClass().getResourceAsStream("/Test.drl")));

        }

        catch(Exception e)

        {

            System.out.println("Error!"+e.getMessage());

        }

        

        //building rule base

        final RuleBase ruleBase=RuleBaseFactory.newRuleBase();

        ruleBase.addPackage(builder.getPackage());//adding package to the
rule base

        

        final WorkingMemory
workingMemory=ruleBase.newWorkingMemory();//creating new working memory

        

        final FactHandle fa=workingMemory.assertObject(taskObj);//asserting
received object from caller

        

        workingMemory.fireAllRules();//firing rules

 

This is my code snippet.

It gives me Null value Exception every time I run the code. Can any one help
me.
