Prefix

[rakesh sugirtharaj]

What is the need for prefix in custom tags?

[Bear Bibeault]

It is the means by which tags are associated with the specific library within which they are defined.

[Christophe Verré]

It is used to identity a library within a page. When you use a tag, you want to tell from which library it comes from. Imagine a scenario where you have two tags with the same name, but from from two different libraries. You need something to tell which tag is from which library, and that's what the prefix is for.

<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<%@ taglib prefix="mylib" uri="http://oioi.com/myLibrary" %>
 
<c:forEach start="1" end="5">
This is JSTL's forEach tag
</c:forEach>
 
<mylib:forEach start="1" end="5">
This is my own forEach tag
</mylib:forEach>
