      >

      my project deploy under weblogic11,and when i run hbase mapreduce,it throws a NullPointerException.i found the method TableMapReduceUtil.findContainingJar() returns null,so i debug it, url.getProtocol() return "zip",but the file is a jar file,so the if condition:
      if ("jar".equals(url.getProtocol())) cann't run. so i add a if condition to judge "zip" type
