Recently began using Jtwig and have no idea how to easily obtain session, servletrequest, remote user and so on. In Thymeleaf, for example, it can be done that way:
<span th:text="${#httpServletRequest.remoteUser}"></span>
...
<p th:text="${#httpSession.getValue(...)}"></p>
Documentation nor Google was not able to answer my question. Probably, this is not implemented (yet?) and i always must put necessary objects manually into the ModelMap?
