XHTML validation JSTL tags

[Graeme Byers]

Is it possible to prevent http://validator.w3.org from flagging tags

<%@ taglib prefix="c"    uri="http://java.sun.com/jsp/jstl/core" %>

as XHTML transitional errors ?

Thank you

I don't know the answer to that, but why would you try to validate a JSP as XHTML?

[Graeme Byers]

Because I will be applying CSS to the XHTML part of the page many authors recommend prior validation for that reason.

No. JSP is not valid XHTML.

There is an XHTML syntax for importing tag libraries.

You include them as part of the <jsp:root> tag

<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page"
  xmlns:c="http://java.sun.com/jsp/jstl/core"
  version="2.0">

But even if you do write your JSP in such a way that it is well-formed XHTML, it's still possible for the JSP to generate output which isn't well-formed XHTML.

+1 to that. In my younger and more idealistic days I tried to do that. Not any more.

That's compliant with XML, but not XHTML.
