    <p>I have a simple class and would like to use @Autowired to trigger the method from numberHandler object. However the object is null. Any ideas? </p> <pre><code>@Component public class Startup implements UncaughtExceptionHandler { @Autowired private MyHandler myHandler; public static void main(String[] args) { startup = new Startup(); startup(args); } public static void startup(String[] args) { startup = new Startup(); } private void start() { ApplicationContext context = new ClassPathXmlApplicationContext("applicationContext.xml"); myHandler.run(); //NULL } </code></pre> <p>applicationContext.xml:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;beans xmlns="http://www.springframework.org/schema/beans" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:util="http://www.springframework.org/schema/util" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context.xsd http://www.springframework.org/schema/util http://www.springframework.org/schema/util/spring-util-2.0.xsd"&gt; &lt;context:annotation-config /&gt; &lt;context:component-scan base-package="com.my.lookup"/&gt; </code></pre> <p></p> <p>and the implementation class:</p> <pre><code>package com.my.lookup; @Component public class MyHandler implements Runnable { private static Logger LOGGER = LoggerFactory.getLogger(MyHandler.class); @Override public void run() { // do something } </code></pre> <p>Do I have to explicit define applicationContext.xml in main class with ClassPathXmlApplicationContext() or is there way for Spring to automatically recognize it in my classpath?</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
