Tomcat 7 web-services, where should i put my image folder and how can i get my images?

Question

My project structure look like this:

Project structure I would like to return a base 64 image took directly from my images folder (in this case, BLUE-CAM1.png).

there is the code where i try to return the image:

@GET @Path("getImage")
public String displayImage()
{
    BufferedImage image;
    try {
         image = ImageIO.read(new File("/images/BLUE-CAM1.png"));

        return image.toString();
    } catch (IOException e) {
        e.printStackTrace();
    }

    return "nothing";
}

But i got this error:

 javax.imageio.IIOException: Can't read input file!

Where should I put the image folder?

Thanks.

我看不到您的项目结构的图像，但是，servlet容器将自动提供META-INF / resources文件夹中存储的资源，因此，如果您将图像打包到此位置的jar文件中（例如META- INF / resources / images / BLUE-CAM1.png），然后从浏览器中访问图像，而无需像上面那样创建rest控制器方法。
