EL Functions x Scripting Elements

[Rafael Pereira]

I really don't get what is the big deal of EL funcions when comparing
to invoking methods directly.

For example, to call the sin() method of Math class, you can:

- Just use a JSP expression:

<%= Math.sin(1.0) %>

- Use it within an EL expression

<%@ taglib prefix="math" uri="WEB-INF/tags/example.tld" %>
${math:sin(1.0)}

(BUT you have to declare it in the example.tld):

<function>
    <name>sin</name>
    <function-class>java.lang.Math</function-class>
    <function-signature>double sin(double)</function-signature>
</function>

So, I think using EL functions is too much work, and using scripting elements are a lot more easier. Am I wrong?

That's weird... Didn't I answer this one already?

Ah ha... I did answer it. There is a problem with the forums and a lot of messages are missing. Someone started a topic for it here.
