Bascially something like:
<html-el:${obj.value.type} property="${obj.value.content}" />
There's no way to that in JSPs; there's no 'eval' mechanism.
Of course a dirty way would be printing out plain html like <input
type="text" :)
Yes, you could do that. Another possibility would be to write a JSP 2.0
tag file containing something like
<c:choose>
<c:when test="${type eq 'text'}">
<html-el:text property="${property}" ...
</c:when>
<c:when test="${type eq '...
and invoke it with
<tag:mytag type="${obj.value.type}"
property="${obj.value.content}" ...
It's cumbersome (and there are some caveats about calling the HTML tags
from a tag file if you want to support optional attributes, which I can
describe if you're interested).
The other way would be write a traditional custom tag in Java and have
it call into the existing HTML tags to do its work.
