从WEB-INF文件夹获取图像

Question

I trie to get an image from my image folder which is placed in the WEB-INF. But i get the NullPointerException.

   Image logo = Image.getInstance(this.getClass().getResource("/resources/img/auditweb.png"));

EDIT:

Have change the code as suggested

Image logo = Image.getInstance(this.getClass().getResource("/WEB-INF/resources/img/auditweb.png"));

But didn't work

Answer 1

neither the root folder of your webapp, not WEB-INF, are in the classpath. You thus can't load a resource that is located there with the ClassLoader, which looks into the classpath.

You need to use ServletContext.getResource() , or to put the images undere WEB-INF/classes .

Answer 2

You are getting NullPointerException because you are providing the wrong path.

Image logo = Image.getInstance(this.getClass().getResource("/WEB-INF/resources/img/auditweb.png"));
                                                             /\
                                                             ||
                                                             ||
                                                             ||
                        Path should start with WEB-INF  ------
