-> JSP Standar Tag Library
-> Library : JSTL 1.2.2
-> mudah membuat kode program dan lebih menghemat baris program
-> ex :
<c:forEach var="i" begin="1" end="5"> item <c:out value="$(i)"> </c:forEach> -> JSTL
<%for(int i=0; i>=5; i++) {%> -> JSP
item <%=i;%>
<%}%>
Jenis-Jenis JSTL :
1. core(http://java.sun.com/jsp/jstl/core, prefix c) : program java biasa
2. xml processing(http://java.sun.com/jsp/jstl/xml, prefix x) : manipulasi dokumen xml
3. sql(http://java.sun.com/jsp/jstl/sql, prefix sql) : relational database
4. function(http://java.sun.com/jsp/jstl/functions, prefix fn) : manipulasi String
5. formatting(http://java.sun.com/jsp/jstl/fmt, prefix fmt) : format dan tampilan date, time, text, number
Langkah-Langkah JSTL :
1. tambahkan file .jar dari package library
2. tag<%@taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%>
3. gunakan tag lain sesuai kebutuhan
Tag lain :
* General Purpose
inisialisasi -> <c:set var="" value="">
print hasil -> <c:out value="$()">
hapus yang di set -> <c:remove var="">
* Iteration
<c:forEach var="" begin="" end=""> </c:forEach>
<c:forToken item="" delims="" var=""> </c:forToken>
* Conditionals
<c:choose> </c:choose>
<c:when> </c:when>
<c:otherwise> </c:otherwise>
