Opa Pessoal beleza?
Estou com uma duvida em implementar uma function TLD que recebe um param
Essa function é simples, recebe um nome e mostra ele no console.
Meu método:
package foo;
public class PrintName {
public static String getStart(String name){
return name;
}
}
TLD
<?xml version="1.0" encoding="UTF-8"?>
<taglib xmlns="http://java.sun.com/xml/ns/j2ee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/j2e.xsde/web-jsptagLibrary_2_0"
version="2.0">
<tlib-version>1.2</tlib-version>
<uri>PrintLibrary</uri>
<function>
<name>printName</name>
<function-class>
foo.PrintName
</function-class>
<function-signature>
java.lang.String getStart(java.lang.String)
</function-signature>
</function>
</taglib>
JSP:
<%@ page language="java" contentType="text/html; charset=ISO-8859-1"
pageEncoding="ISO-8859-1"%>
<%@taglib prefix="p" uri="/WEB-INF/tld/PrintLibrary.tld" %>
<html>
<body>
${p:printName(${param.name})}
</body>
</html>
