Also double check that you are importing the right resin-pro-4.0.12/lib stuff, and don't have a reference to the older lib jar files -- I've been bitten by that a time or two.

Yes, that's exactly what I was doing that was failing in resin-pro.4.0.10, but not in resin-pro-4.0.12. Try deleting your entire WEB-INF folder and let resin-pro-4.0.12 reconstruct it, just to make sure you don't have old 4.0.10 compilations hanging around. There is definitely a behavior change in chaining imports from 10 to 12, and it's working for me in 12.

I am also doing a c:import on an xml document in the final c:import, so we are doing the same thing.

I just upgraded to resin-pro-4.0.12 and it is still happening...at least on OS X. It also happens for non JSPs. I have some pages that import XSL and XML files so I can parse them with the x tag library and those imports also fail. There is no chaining of imports that I can see.

What version of Resin 4.0 are you using? I can reproduce this easily on resin-pro-4.0.10 by doing this:

--  create test.jsp:
<%@ taglib uri="http://java.sun.com/jsp/jstl/core"; prefix="c" %>
<c:import url="test2.jsp" var="debug"/>
${debug}
--

-- create test2.jsp
<%@ taglib uri="http://java.sun.com/jsp/jstl/core"; prefix="c" %>
<c:import url="test3.jsp" var="debug"/>
${debug}
--

-- create test3.jsp
<%@ taglib uri="http://java.sun.com/jsp/jstl/core"; prefix="c" %>
Some output.
--

Then just call: http://localhost/test.jsp

And it will throw your error. It only happens when one c:import calls another one.

This behavior is completely fixed in resin-pro-4.0.12 though (and was working in resin-4.0.6, so it broke some time after that release).

I seem to have issues using JSTL c:import within Resin 4.0. Below is my code and the error. Any ideas? Does Resin 4.0 no longer support the import tag?

FYI...my:frame is a custom tag that eventually executes jsp:doBody.
