– Message Body ——————————-

I included the following on a simple jsp page
<%@ taglib prefix=”c” uri=”http://java.sun.com/jstl/core&#8221; %>

standard.jar and jstl.jar are in the WEB-INF/lib folder
the tlds are in the WEB-INF folder.

jsp-api.jar, jstl.jar and standard.jar have been added to the project build path.

the following code is in the jsp file:
<c:if test=”${true}” >
<label>You have 2 rows</label>
</c:if>
Problem:
the <c:if tags are underlined and say “Unknown Tag”

Please Help,

Thanks

The TLDs are actually in the standard.jar file, you need to add that to your build path. Also the URIs you are using are for JSTL 1.0, so if you add standard and it’s STILL not working, expand the standard.jar file and go into the META-INF folder and open the c.tld file, look near the top for the <uri></uri> section and use that URI.

TIP: Your TLDs when using default URIs are resolved from the JARs, so you don’t need them in WEB-INF.

The taglib is now
<%@ taglib prefix=”c” uri=”http://java.sun.com/jsp/jstl/core&#8221; %>

the standard.jar file has been added to the project.

the <c:if tags still have the same error.

Try and restart MyEclipse then rebuild your project.

Also do you have any <taglib> entries in your web.xml file? These will override default URIs.

[sgadkari]

I have already removed references to taglib from web.xml.

Restarting eclipse and rebuilding did not help.

I need to clarify is this actually a web project or a Java project? Open project properties, go to MyEclipse-Web, what are your 2 values in the text fields there?

If this is not a web project, you can Add Web Project Capabilities to it from the MYEclipse sub-menu off of the root of your project (right-click).

That solved the problem.

Thank you for your help.
