Answer 1

You must use ServletContext.getResourceAsStream() to load a file from a war. ClassLoader.getResourceAsStream loads a class from the classpath.

Answer 2

As far as I know the classLoader can only access WEB-INF/classes and WEB-INF/lib but not WEB-INF/resources. Try to put the file in the classes sub-folder.

Answer 3

I think you're confusing ClassLoader#getResourceAsStream() with ServletContext#getResourceAsStream(). The former only loads resources from the classpath while the later only loads resources from the webcontent (there where your /WEB-INF folder also is).

You need to put those resources in the classpath. If you're using an IDE, then most straightforward way is to just drop them in any package in the Java source folder. It'll end up in /WEB-INF/classes after build, which is part of the classpath.

Lets assume that you've a package com.example.resources.images and you've dropped logoemailtemplate.png file in there, then you can load it by the following fileName.

String fileName = "/com/example/resources/images/logoemailtemplate.png";

An alternative is to add /WEB-INF/resources folder to the classpath. In an IDE like Eclipse, you can do that by adding it as Source folder in project's build path. Then you can load it by the following fileName.

String fileName = "/images/logoemailtemplate.png";

This is however not the common practice.
