    copied!<p>I'm moving my knowledge to spring and I dont really get how this is working. I'm trying to make a very basic example to make it work, but I couldn't make it work :-(( </p> <p>ApplicationContext.xml</p> <pre><code>&lt;bean id="serviceTest" class="es.mov.jose.agenda.ServiceTest"&gt; &lt;/bean&gt; &lt;bean id="serviceMovility" class="es.mov.jose.agenda.ServiceMovility"&gt; &lt;property name="serviceTest" ref="serviceTest" /&gt; &lt;/bean&gt; &lt;bean name="/jose/req1.do" class="org.springframework.web.servlet.mvc.ParameterizableViewController"&gt; &lt;property name="viewName" value="jose/req1" /&gt; &lt;/bean&gt; </code></pre> <p>ServiceMovility.java</p> <pre><code>package es.mov.jose.agenda; public interface ServiceMovility { public String callTest(); } </code></pre> <p>ServiceMovilityImpl.java</p> <pre><code>package es.mov.jose.agenda; import es.mov.jose.agenda.ServiceMovility; public class ServiceMovilityImpl implements ServiceMovility { private ServiceTest serviceTest; public String callTest() { return serviceTest.getValue(); } } </code></pre> <p>ServiceTest.java</p> <pre><code>package es.mov.jose.agenda; public interface ServiceTest { public String getValue(); } </code></pre> <p>ServiceTestImpl.java</p> <pre><code>package es.mov.jose.agenda; import es.mov.jose.agenda.ServiceTest; public class ServiceTestImpl implements ServiceTest { public String getValue() { return "OK"; } } </code></pre> <p>and finally my req1.jsp </p> <pre><code>&lt;?xml version="1.0" encoding="ISO-8859-1" ?&gt; &lt;!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"&gt; &lt;html&gt; &lt;head&gt; &lt;%@ page language="java" contentType="text/html; charset=ISO-8859-1" pageEncoding="ISO-8859-1"%&gt; &lt;%@ page import="es.mov.jose.agenda.ServiceMovility"%&gt; &lt;%@ page import="es.mov.jose.agenda.ServiceMovilityImpl"%&gt; &lt;%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core"%&gt; &lt;%@ taglib uri = "http://java.sun.com/jsp/jstl/functions" prefix="fn"%&gt; &lt;%@ taglib prefix="sp-forms" uri="http://www.springframework.org/tags/form"%&gt; &lt;%@ taglib prefix="spring" uri="http://www.springframework.org/tags"%&gt; &lt;meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1"&gt; &lt;/head&gt; &lt;body&gt; &lt;jsp:useBean id="serviceMovility" scope="request" class="es.mov.jose.agenda.ServiceMovilityImpl" /&gt; &lt;div class="main" &gt; &lt;% String result = serviceMovility.callTest(); out.println(result); %&gt; &lt;/div&gt; &lt;/body&gt; &lt;/html&gt; </code></pre> <p>It call serviceMovility perfectly but fail calling serviceTest inside callTest method, it says java.lang.NullPointerException ¿Should I include the bean serviceMovility in that way in jsp file? ¿Why spring doesn't inject serviceTest initialized on serviceMovility?</p> <p>I spent 2 days on this but I failed on all my solutions. I don't know what to do.</p> <p>Thanks in advance. </p>
