<%= %> [and others like <% %>] are JSP tags which wrap Java.
gui.displaySex is Java.
I'm skating a little fine with the definitions, but the basic problem is
that you have JSP code where the system expects Java code.
Would you expect:
<img src="http://example.com/index.html";> to work?
No, because an image doesn't expect a html page, it expects an image, be
in png/jpeg/gif etc. Same thing here. <% %> <%= %> effectively mark the
entry into a different type of context, similar to how " marks the exit
from Java syntax and entry into String syntax.
ie) "if {" is different to if {
The rtexpr bit means that you could do:
<c:out value="value--[<c:out value="foo"/>]"/> or some such
ie) a c:out in the attribute of another c:out [or other tag].
