"EL" are the JSTL expression language tags that you're
using.
"RT" are the JSTL runtime tags that can be used with
scripting expressions (<%= ... %>).
Perhaps you want to be using the RT tags.
If you've downloaded the JSTL library from Jakarta,
you've already got both the EL and RT tag libraries.
They come as a set.
Shawn Bayern's "JSTL In Action" book explains all this
very nicely.
