問題

  • ServletプラグインのdoGetメソッドにJSPを含めたいのですが、どうすればいいですか? 以下はNullPointerExceptionが発生します。
    この.getServletContext().getRequestDispatcher("index.jsp").include(httpServletRequest, httpServletResponse);

環境

  • Liferay DXP 7.1

解決策

  • Web-ContextPath を追加する bnd.bnd
  • のようにServletContextの@Referenceを追加します:
    @Reference(
    target = "(osgi.web.symbolicname=com.liferay.blade.samples.servlet)"
    )
    private ServletContext servletContext;
    doGet()メソッドでこのservletContextを使用して、ディスパッチャを取得します。
    RequestDispatcher dispatcher = servletContext.getRequestDispatcher("/welcome.jsp");
    dispatcher.include(request, response);
