I want to write a simple web page in .jsp file. I need to use <c:if>
tag. but it is not recognized. eclipse said it is unknown tag.
I googled it and some said I need to include the standard lib (which is JSTL?).
I just want to use some basic tags in jsp file such as <c:if>
. Do I really need to include any libraries?
If so, what libraries do I need to include? And how to do that in Eclipse?
Please let me know step by step about how to import/include these libraries or build path so that I can use <c:if>
in my jsp file.
Make sure that you have a taglib declaration in your JSP file
<%@ taglib
prefix="c"
uri="http://java.sun.com/jsp/jstl/core"
%>
Also, make sure that you've added JSTL jar files to your project classpath.
