No No No.
It's simple to 'out' the value of a variable.
What I'm looking for is to 'out' a tag-lib component itself. Say, I have
some components that can be rendered as:
<tag_prefix:xyz/>
<tag_prefix:abc/>
<tag_prefix:pqr/>
I want 'xyz'/'abc'/'pqr' to be dynamic. If you don't understand, here's
what I mean:
----------------------------------
Vector v; // contains a list of components, eg: v.add(abc), v.add(xyz),
v.add(pqr)
// abc instanceof MyComponent1
// pqr instanceof MyComponent2
// xyz instanceof MyComponent3
<c:forEach var="i" items="${v}">
<tag_prefix:${i}/>
</c:forEach>
----------------------------------
This is a summary of what I want.
I hope that makes things clearer.
Or am I still unable to express myself? :(
Cheers,
Gaurav
