I'm using Maven and Spring and my EL doesn't seem to be working on my JSP. I end up seeing this as a result.
The JSPs work and the GET and POST methods seem to be functioning fine. It just doesn't seem to recognize the EL. I have have tried using JSTL too but both the EL and JSTL expressions are read as static text. I've been trying every combination of dependencies I could find but to no avail. If anyone has had issues with this before please help.
