Resource file not found after war file deployed upon wildfly8

Question

I've created dynamic web project in Eclipse and added it to ear project.

Image resources are placed at src\resources\

Code use resources:

@GET
@Path("bank")
@Produces("application/json")
public String getBank(@Context HttpHeaders headers) {
  ClassLoader classLoader = getClass().getClassLoader();
  File file = new File(classLoader.getResource("/resources/alfa.png").getFile());
  String base64 = Utility.getBase64(file);
  return "{\"icon\":\"" + base64 + "\"}";
}

While debugging it's OK.

When ear deployed code throws exception: java.io.FileNotFoundException: C:\apps\wildfly-8.2.0.Final\bin\content\TimerService.ear\timer.war\WEB-INF\classes\resources\alfa.png

All resources are present in war-file contained in ear-file.

What is wrong?

You can't reference class path resources as java.o.File objects because they will often not exist file system as distinct file system objects. Modify Utility.getBase64 to take a java.io.InputStream instead. — Steve C, Jan 10 '16 at 10:32

this way it should work

@GET
@Path("bank")
@Produces("application/json")
public String getBank(@Context final HttpServletRequest request) {
  ClassLoader classLoader = request.getServletContext().getClassLoader();
  File file = new File(classLoader.getResource("/resources/alfa.png").getFile());
  String base64 = Utility.getBase64(file);
  return "{\"icon\":\"" + base64 + "\"}";
}
