Can you share your directory structure here ? This issue may be just resolved by correctly referencing your JSP page . Also Keep in mind that all URL paths starting with a backslash "/" means they are relative to context root the and the context will not get pre-pended.
Java docs wrote: The pathname specified may be relative, although it cannot extend outside the current servlet context. If the path begins with a "/" it is interpreted as relative to the current context root. This method returns null if the servlet container cannot return a RequestDispatcher.

The source directory structure and deployment directory structure may be different. Its the deployment directory structure that really matters.
Here your path to the JSP starts with "/" meaning you are referring this JSP from the ROOT of your web-app.
Your WEB-INF structure should reflect this.
