    • getNextPathPart

      public static java.lang.String getNextPathPart​(java.lang.String path, java.lang.String lastPart) throws javax.servlet.ServletException

      lastPart - the previousPart of the path to search after.
      Returns:
      the next part of the path.
      Throws:
      javax.servlet.ServletException - if path does not contain lastPart
