Hi Rajesh,

	You MUST use the org.drools.util.BinaryRuleBaseLoader to load a  
precompiled binary package into your RE classes.

     public void testLoadAndExecBinary() throws Exception {
         Person p = new Person();
         BinaryRuleBaseLoader loader = new BinaryRuleBaseLoader();
         loader.addPackage( this.getClass().getResourceAsStream( "/ 
RepoBinPackage.pkg" ) );
         RuleBase rb = loader.getRuleBase();
         StatelessSession sess = rb.newStatelessSession();
         sess.execute( p );
         assertEquals(42, p.getAge());
     }
