    <p>I have programatically defined a Jetty server and added an instance of a HttpRequestHandlerServlet. I am trying to do all of this without a web.xml file. Here is a simplified version of my code:</p> <pre><code>import java.io.IOException; import java.util.Enumeration; import javax.servlet.ServletConfig; import javax.servlet.ServletContext; import javax.servlet.ServletException; import javax.servlet.http.HttpServletRequest; import javax.servlet.http.HttpServletRequestWrapper; import javax.servlet.http.HttpServletResponse; import javax.servlet.http.HttpServletResponseWrapper; import org.eclipse.jetty.server.Request; import org.eclipse.jetty.server.Server; import org.eclipse.jetty.servlet.ServletContextHandler; import org.eclipse.jetty.servlet.ServletHolder; import org.junit.Test; import static org.mockito.Mockito.*; import org.springframework.context.support.StaticApplicationContext; import org.springframework.web.HttpRequestHandler; import org.springframework.web.context.WebApplicationContext; import org.springframework.web.context.support.GenericWebApplicationContext; import org.springframework.web.context.support.HttpRequestHandlerServlet; public class TestServer extends Server { public TestServer() throws Exception { super(8888); final ServletContextHandler contextHandler = new ServletContextHandler(this, "/", ServletContextHandler.NO_SESSIONS|ServletContextHandler.NO_SECURITY); final ServletContext context = contextHandler.getServletContext(); StaticApplicationContext applicationContext = new StaticApplicationContext(); applicationContext.registerSingleton("testServlet", TestBean.class); applicationContext.refresh(); GenericWebApplicationContext webApplicationContext = new GenericWebApplicationContext(); webApplicationContext.setParent(applicationContext); webApplicationContext.setServletContext(context); webApplicationContext.refresh(); context.setAttribute(WebApplicationContext.ROOT_WEB_APPLICATION_CONTEXT_ATTRIBUTE, webApplicationContext); ServletConfig servletConfig = new ServletConfig() { @Override public String getServletName() { return "testServlet"; } @Override public ServletContext getServletContext() { return context; } @Override public String getInitParameter(String name) { return null; } @Override public Enumeration&lt;String&gt; getInitParameterNames() { return null; } }; HttpRequestHandlerServlet httpRequestHandlerServlet = new HttpRequestHandlerServlet(); httpRequestHandlerServlet.init(servletConfig); ServletHolder servletHolder = new ServletHolder(httpRequestHandlerServlet); contextHandler.addServlet(servletHolder, "/testBean"); start(); } @Test public void test() throws Exception { TestServer testServer = new TestServer(); Request baseRequest = new Request(); HttpServletRequest request = mock(HttpServletRequestWrapper.class); HttpServletResponse response = mock(HttpServletResponseWrapper.class); testServer.handle("/testBean", baseRequest, request, response); } } class TestBean implements HttpRequestHandler { @Override public void handleRequest(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException { response.getOutputStream().write("Steve".getBytes()); } } </code></pre> <p>If you run the test, the following exception (root cause) occurs:</p> <blockquote> <p>Caused by: org.springframework.beans.factory.NoSuchBeanDefinitionException: No bean named 'org.springframework.web.context.support.HttpRequestHandlerServlet-406774688' is defined at org.springframework.beans.factory.support.DefaultListableBeanFactory.getBeanDefinition(DefaultListableBeanFactory.java:570) at org.springframework.beans.factory.support.AbstractBeanFactory.getMergedLocalBeanDefinition(AbstractBeanFactory.java:1108) at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:278) at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:198) at org.springframework.beans.factory.support.AbstractBeanFactory.doGetBean(AbstractBeanFactory.java:270) at org.springframework.beans.factory.support.AbstractBeanFactory.getBean(AbstractBeanFactory.java:198) at org.springframework.context.support.AbstractApplicationContext.getBean(AbstractApplicationContext.java:1121) at org.springframework.web.context.support.HttpRequestHandlerServlet.init(HttpRequestHandlerServlet.java:58) at javax.servlet.GenericServlet.init(GenericServlet.java:241) at org.eclipse.jetty.servlet.ServletHolder.initServlet(ServletHolder.java:477)</p> </blockquote> <p>I am using Jetty 7.6.9.v20130131 (due to a dependency in my real project on Camel 2.12.1) and Spring 3.2.4.RELEASE.</p> <p>Any help is greatly appreciated.</p> <p>Steve Ardis</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.

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).
