There is no API for this. Indeed, in JSP 2.0 if you use simple tags there is no pooling of tag instances either.

What you need to build forms like this dynamically is a component model like the one provided by JavaServer Faces or Tapestry. The Shale framework[1] (also part of the Struts community), built on top of JSF, has an example of building views dynamically that is somewhat different than your use case (it lets you do SQL Browser queries, and dynamically decides what columns to show in the output table based on which database columns were returned in response to executing the query), but illustrates the principle. It would be straightforward, for example, to dynamically generate a set of field labels and input fields based on the columns in a database, or the properties of a JavaBean. Trying to dynamically construct JSP code and then "re-evaluate it" is not the right approach to this kind of problem.
