JSP cannot parse the solution of the EL expression

The reason: by default, Servlet 2.4 / JSP 2.0 supports EL expressions.
There are two solutions:
1. Modify the beginning definition of web.xml.
This configuration represents Servlet 2.4 / JSP 2.0.
2. Add a line of code to the beginning of the page where the EL expression is used.
So far, however, I have only tried the second method. If there is any other method, please let me know.
