Problem Description:

    1. Use jsp to use the four domains of the domain (pageContext, request, session, application), and simply access data to the domain.

    2. There is no problem with removing other domains from the pageContext domain. prompts can appear. At the time of writing this article, the pageContext still cannot prompt

problem solved:

    I searched on the Internet, and there was a person who also had the same problem, but it was caused by missing a }. And I double checked the syntax and there are no errors.

    Then visited a few more times and suddenly it was no problem again.

Summarize:

    It should be a compiler problem. Try turning it off and turning it on.

     Hope this article is useful to you! ! !
