Thank you:
This looks close to what I need. But I think I am missing something
here. I am setting an abject value in the Action. Where is this object
stored, on the ValueStack ? Basically I am setting a resuletSet in the
action and I need a tag to display it, so How can I access it from the tag.
I tried this:
ActionContext a = ActionContext.getContext();
Object value = a.getValueStack().findValue("results");
but it's not working.

"There is a simple, if not elegant, solution available in JSP 2.0 EL,
for exposing ValueStack to OGNL. It is possible to create custom
functions that can be called from EL expressions. Functions have to be
'public static' and specified in a TLD file.
To use a function, import the TLD in a JSP file where you've want to
use a function."

Subject: Custom component - custom tag
where do I find tutorial about writing my own UI component ?
I wrote a tag already to be used with JSP then when I tried it with
struts 2 it didn't work. Basically, because I am passing the object
as string and trying to retrieve it form the context in the custom
tag. This is not working because struts ( I believe passes it into a
valueStack). How do I rewrite my tag. Is there a tutorial ?
