Example:

if(age == 18) {
//some action
}
else {
//some other action
}

In Struts:
<logic:equal name="age" value="18">

</logic:equal>
<logic:notEqual name="age" value="18">

</logic:notEqual>

Cheers,
Aj

Holy crap. Why do they even bother?

I'm sorry, it's not your fault, but why on Earth would anybody bother
using taglibs for this sort of thing when it makes the whole thing so
much more obscure? Scriptlets aren't something to be ashamed of - they
work well, they're efficient, and they're perfectly readable to anybody
who knows Java.

Sorry to vent, but I really, really, REALLY dislike Struts.

Whenever I see something like this, I'm praying that it's some kind of
auto-generated thing, and that the input to the generator is simpler
than the output.

Clearly there is a type of person that enjoys declarative programming
syntax using XML constructs, and there are lots of that type out there,
but I've never been one of them, and I hope I don't have to become
one...

It's not a taglib issue, it's a Struts issue. I like Struts mostly, and I
use Struts, but the lack of an "else" clause *is* just stupid.

But again, why bother? For something that is so readily available via
scriptlets? It just leads to a splintering of standards so that I can't
read your code, because you employ a taglib that I don't know. Struts is
the major player, but there are other such. I honestly fail to see the
need for them.

I employ my own custom Javabeans quite frequently, but of taglibs I have
none, and I plan to keep it that way.
