I'm having an error like this:

<h3>Validation error messages from TagLibraryValidator for f in /user/ace/branch/activeComments.jsp</h3>

null: Validation error. The following JSF tags are required to contain IDs:"hutputLink hutputText "





The error happens when I place this code to the page. Please help. Thanks.

I don't know why JSF is insisting on putting IDs on those tags. It doesn't normally do that. You should be able to satisfy it by coding 'id="xxxxxx"' attributes on the indicated elements, where "xxxxxx" is a different and unique ID for each element so identified.

But you're not using JSF very gracefully. JSTL should almost never be mixed with JSF. In most cases, JSF has a better-integrated way of doing the same thing. Likewise, you should avoid raw HTML, which, depending on the version of JSF you're using may disappear or get relocated to the wrong part of the display.

edited: I'll leave this here though i totally missed the point or was replying to something else with the wrong page open at the time.

<c:if test="${param.something == true}"....

is JSTL Java Standard Tag Library.

you nees this
<%@ taglib uri="http://java.sun.com/jsp/jstl/core" prefix="c" %>
at the top of the page and the JSTL .jar files for the
WEB-INF/lib
in your application.
And you can hot fix it too if you want by using e.g. winrar archiver that shows folders not a list
and take all the .tld files out of the .jar files that have any in there META-INF and put them(.tld) in
the /WEB-INF of your app.
