Create a custom tag that uses struts HTML tags?

[John Averty <jo...@hotmail.com>]

Hi,

I'm a new struts user, and I couldn't find any information that helped;

I'd like to create a custom tag which represents a super-componant such as a "properties list" tag.

The idea would be to:
1) dynamically specify which fields to be renderered
2) at the same time ensure that the rendering of such list of properties is consistant accross different pages of the application, without having to rely on "low level" HTML (such as tables, etc) on each page.

So the question is: 

How can I reference Struts tags from withing my tag
 - without having to put a lot of snipet code in the jsp page (I'd like just the tag and a definition name)
 - still having the struts built-in validations mechanism work.

I'm assuming I might be able to get to the struts tags by some sort of introspecion mechanism, but I'm not clear on how to have the validation perform.

Any help grandly apprecitated.

Chheers,

John.

Have you discovered the <tiles:insert> tag yet?  Sounds to me like this 
is what you're wanting ... no need to re-invent the wheel if you don't 
have to.  (you said definition - that's tiles nomenclature - that's why 
I made my assumption ... ).  If you're not looking at tiles, you may 
want to.  It's conceivable it may suit your needs (defining reusable 
"chunks" which can be rendered at any given point).

Of course, if I _totally_ missed your point, just repost with more 
information.

Regards,

Eddie

Could you explain this a bit further.

I've written a few tags myself, but I'm not exactly sure what you are trying
to do.
