No, I'm afraid not. If I read the requirement correctly, Ben wants a way to evaluate a custom action that's not in the requested page but rather in a String available to the page at runtime. There's nothing in the JSP specifaction that allows you to dynamically invoke the tag handler for a custom action at runtime. That said, everything is possible. You could use a custom tag that parses the string, locates the tag handler matching the custom action so some means (no support for doing this generically in the spec), and calls all setters and doXXX() methods according to the rules defined in the spec. I strongly discourage such a solution, though. Ben, if you tell us what the end goal is, maybe we can suggest an alternative solution.
