You can either add the support in your tag to handle the OGNL yourself (it's
not too hard, but then again it ain't easy either). Or you can use the
"var" (or "id") attribute support that most of the struts tags have to move
the value from the OGNL stack to the page scope where the JSTL EL tags can
see it, then use the ${} notation to pass the values into your tags.
If you decide to go the first route, let me know and I may be able to point
you in a workable direction (I can't say for sure that it's the right
direction, but it works well for me)
