The above code throws warning on the development machine,but it creates the correct path and eventually opens the file correctly. But, in case of production environment, where the platform os is Windows, it throws a null pointer exception on the following line--->

上面的代码在开发机器上抛出警告,但它会创建正确的路径并最终正确打开文件。但是,在生产环境中,平台os是Windows,它会在以下行--->上抛出空指针异常

URL helpDocument=NewCellTrenderGUILauncher.class.getClass().getResource("/G1-G2Help.doc");
