Can a custom tag return a jsp tag?

[John Pritchard]

Hi all-
I am fumbling through the correct implementation of the Composite View pattern using custom tags to may runtime determinations of JSP content. I have a custom tag that evaluates the username/password of the user at login and performs a set of :

out.println("<jsp:include page=\"blahblah.jsp\" />");

statements among others. The problem is that all of the html tags that appear in my out.println statements get evaluated fine by the JSP. None of the jsp:includes do however. The statements do end up in the source returned to the browser however. For example if I do a view source on the resulting webpage, I see all the <jsp:include> tags it's just they were not interpretted. I've been through the Professional JSP text but are unable to find a definitive answer if you can return jsp tags in a custom tag. I'm using Weblogic 7.0.
hmmm

No, the JSP tags are evaluated at translation time, and your custom tags execute at run time -- long after the JSP tags have been evaluated.
For your particular problem, remember that the value of the page attribute on the jsp include tag can be a run-time value, and you can perform an include operation from within the custom tag code.
