    It will be empty if you deployed the webapp on ROOT. See also its javadoc (emphasis mine):

    getContextPath

    java.lang.String getContextPath()

    Returns the portion of the request URI that indicates the context of the request. The context path always comes first in a request URI. The path starts with a "/" character but does not end with a "/" character. For servlets in the default (root) context, this method returns "". The container does not decode this string.

    Are you sure that you did deploy it on a context path? Note that the context path doesn’t contain the scheme/domain part of the URL, it’s a domain-relative URL.
