  1. The 'filmList' attribute is not set in the FilmServlet: Make sure that the 'filmList' attribute is set correctly in the FilmServlet before forwarding the request to the index.jsp page. Double-check the implementation of the QueryAllFilmServiceImpl and ensure that it is returning a valid List\u003cFilm\u003e object.

  2. The 'filmList' attribute is not being forwarded correctly: Verify that the req.getRequestDispatcher('/index.jsp').forward(req, resp) statement is being executed and that the request is being forwarded to the correct path ('/index.jsp'). Check for any typos or incorrect paths in the forward statement.

  3. The JSTL taglib is not properly imported: Ensure that the JSTL taglib is imported correctly at the beginning of the index.jsp file. The taglib declaration should be as follows:\u003c%@ taglib prefix='c' uri='http://java.sun.com/jsp/jstl/core'%3e

  4. The JSTL library is not included in the project: Make sure that the JSTL library (jstl.jar or jstl-1.2.jar) is included in the project's build path. If the library is missing, you can download it from the official Apache website and add it to your project.

  5. The JSTL core tags are not used correctly: Double-check the usage of the c:forEach tag in the index.jsp file. Ensure that the 'filmList' attribute is correctly referenced within the tag as '${filmList}'.

By addressing these potential issues, you should be able to resolve the problem and have the index.jsp page receive the 'filmList' request attribute successfully.
