As you have noticed, the EL syntax is not up to the task you're after (of
course, <bean:write> is not going to be, either). But, I suggest you
consider a completely different approach.
When you execute an EL expression like this:
${foo.bar}
what's really happening is that a bean named "foo" is found, and then it's
getBar() method is called. So, why not write a getBar() function on some
bean class that returns the entire set of argument names and values for
you? In other words, do the looping in Java code rather than JSP. If this
method were on the same class that contains the list or array being iterated
over, it should have everything it needs to calculate the appropriate
parameter values.
As a general principle, I believe that manufacturing URLs in the JSP code
(as you are attempting here) is working too hard ... and it is really mixing
elements of the controller into the view in undesireable ways. Much better
to write code in the controller that can calculate all that stuff for you,
and then let the view code pull it out with a simple EL reference.
