    <p>I'm trying to learn annotations. I currently have a webapp that runs an init() when the app is started in Tomcat.</p> <p>The following code works...</p> <p>web.xml:</p> <pre><code>&lt;?xml version="1.0" encoding="UTF-8"?&gt; &lt;web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_3_0.xsd" version="3.0"&gt; &lt;servlet&gt; &lt;servlet-name&gt;MainServlet&lt;/servlet-name&gt; &lt;servlet-class&gt;com.company.Main&lt;/servlet-class&gt; &lt;load-on-startup&gt;1&lt;/load-on-startup&gt; &lt;/servlet&gt; &lt;/web-app&gt; </code></pre> <p>Main.java:</p> <pre><code>import java.io.IOException; import javax.servlet.*; import javax.servlet.annotation.WebServlet; //@WebServlet(name="MainServlet", value="/main.jsp", loadOnStartup=1) public class Main extends GenericServlet { public Main() { } @Override public void init() { System.out.println("Hello!"); } @Override public void destroy() { System.out.println("Bye!"); } @Override public void service(ServletRequest req, ServletResponse res) throws ServletException, IOException { } } </code></pre> <p>However, when I uncomment the @WebServlet annotation and comment out the servlet entry in web.xml, the init method doesn't run.</p> <p>Am I missing something obvious?</p> <p>In case this will help, this is my pom.xml:</p> <pre><code>&lt;project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd"&gt; &lt;modelVersion&gt;4.0.0&lt;/modelVersion&gt; &lt;groupId&gt;...&lt;/groupId&gt; &lt;artifactId&gt;...&lt;/artifactId&gt; &lt;packaging&gt;war&lt;/packaging&gt; &lt;version&gt;1.0-SNAPSHOT&lt;/version&gt; &lt;name&gt;Name&lt;/name&gt; &lt;url&gt;http://maven.apache.org&lt;/url&gt; &lt;build&gt; &lt;plugins&gt; &lt;plugin&gt; &lt;groupId&gt;org.apache.maven.plugins&lt;/groupId&gt; &lt;artifactId&gt;maven-compiler-plugin&lt;/artifactId&gt; &lt;version&gt;2.0.2&lt;/version&gt; &lt;configuration&gt; &lt;source&gt;1.6&lt;/source&gt; &lt;target&gt;1.6&lt;/target&gt; &lt;/configuration&gt; &lt;/plugin&gt; &lt;/plugins&gt; &lt;/build&gt; &lt;dependencies&gt; &lt;dependency&gt; &lt;groupId&gt;junit&lt;/groupId&gt; &lt;artifactId&gt;junit&lt;/artifactId&gt; &lt;version&gt;3.8.1&lt;/version&gt; &lt;scope&gt;test&lt;/scope&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;org.springframework&lt;/groupId&gt; &lt;artifactId&gt;spring-core&lt;/artifactId&gt; &lt;version&gt;3.0.5.RELEASE&lt;/version&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;org.springframework&lt;/groupId&gt; &lt;artifactId&gt;spring-tx&lt;/artifactId&gt; &lt;version&gt;3.0.5.RELEASE&lt;/version&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;org.hibernate&lt;/groupId&gt; &lt;artifactId&gt;hibernate-core&lt;/artifactId&gt; &lt;version&gt;3.6.6.Final&lt;/version&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;org.hibernate&lt;/groupId&gt; &lt;artifactId&gt;hibernate-annotations&lt;/artifactId&gt; &lt;version&gt;3.5.6-Final&lt;/version&gt; &lt;/dependency&gt; &lt;dependency&gt; &lt;groupId&gt;javax&lt;/groupId&gt; &lt;artifactId&gt;javaee-web-api&lt;/artifactId&gt; &lt;version&gt;6.0&lt;/version&gt; &lt;scope&gt;provided&lt;/scope&gt; &lt;/dependency&gt; &lt;/dependencies&gt; &lt;/project&gt; </code></pre>

    2. CONo, it's not registering the servlet with the container at all. I have a few other servlets that extend HttpServlet and their service methods, which have content, are not run either.

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.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
