Subject dynamic attributes
Date Thu, 23 Nov 2000 05:06:25 GMT
Hi,

Is there any way to dynamically create attributes for JSP taglib elements?

Eg, how would I do the following:

<util:include
url="/servlet/MyServlet?q=<%request.getParameter("param");%>" />

? I'd like Tomcat to first evaluate <% request.getParameter("param"); %>,
and then feed that to <util:include url="..."/>.


Cocoon (http://xml.apache.org/cocoon) handles the above as follows:

<util:include>
  <util:url>
  /servlet/MyServlet?q=<xsp:expr>request.getParameter("param")</xsp:expr>
  </util:url>
</util:include>

So every attribute also has an equivalent "nested element" form. That's
possible because Cocoon XSP taglibs are written in XSLT, whereas JSP has a
more rigid API-based model.

Is any general way of doing this?

thanks,

--Jeff
