This is my original post.
I've have read the contents and tried multiple things.
I believe what's occurring is my JSTL has its own EL ${} tag, and my JSP has its own EL ${} tag. I feel like they are colliding making the memory space null or cleared.
Question: How can I configure Eclipse to accept one and disable the other?
Correct me if I'm wrong but isn't my current version 4.0 using Dynamic Web Project. Does this only work in Maven Projects?
Is jstl-1.2.jar using a strict version dynamic web project? Is this the issue? Should I go down to Dynamic Web Project 3.0? Or even 2.5? Should I get a different jar file?
Once again I'm a junior software developer trying to understand why my jar file isn't working properly in comparison to the JSP in my dynamic web project. Please be gentle :D
This is to show you what is happening when I run from the server.
