<p>I'm trying to build an application using Spring MVC 3.0 within Eclipse using the Dynamic Web Project. I'm able to get to the initial page, but I can not navigate to any other pages from there w/out getting a 404 error and I'm not hitting any of my breakpoints in the controller class. Please let me know if there's something I'm missing. Thanks!</p> <p>applicationContext.xml Code:</p> <pre><code><?xml version="1.0" encoding="UTF-8"?> <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:mvc="http://www.springframework.org/schema/mvc" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">  <context:annotation-config />  <context:component-scan base-package="src" />  <mvc:annotation-driven />  <import resource="hibernate-context.xml" /> </beans> </code></pre> <p>spring-servlet.xml Code:</p> <pre><code><?xml version="1.0" encoding="UTF-8"?> <beans xsi:schemaLocation=" http://www.springframework.org/schema/beans ... xmlns:mvc="http://www.springframework.org/schema/mvc" xmlns:aop="http://www.springframework.org/schema/aop" xmlns:context="http://www.springframework.org/schema/context" xmlns:p="http://www.springframework.org/schema/p" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://www.springframework.org/schema/beans"> <bean class="org.springframework.web.servlet.mvc.annotation.DefaultAnnotationHandlerMapping" /> <bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter" />  <bean id="viewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="viewClass" value="org.springframework.web.servlet.view.JstlView"/> <property name="prefix" value="/WEB-INF/jsp"/> <property name="suffix" value=".jsp"/> </bean> </beans> </code></pre> <p>web.xml Code:</p> <pre><code><?xml version="1.0" encoding="UTF-8"?> <web-app id="WebApp_ID" version="2.4" 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/j2ee http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"> <servlet> <servlet-name>spring</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <init-param> <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/applicationContext.xml </param-value> </init-param> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>spring</servlet-name> <url-pattern>/SpringHibernateExample/*</url-pattern> </servlet-mapping> <welcome-file-list> <welcome-file>/jsp/personspage.jsp</welcome-file> </welcome-file-list> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> </web-app> </code></pre> <p>MainController.java Code:</p> <pre><code>package controller; import java.util.List; import javax.annotation.Resource; import org.apache.log4j.Logger; import org.springframework.stereotype.Controller; import org.springframework.ui.Model; import org.springframework.web.bind.annotation.ModelAttribute; import org.springframework.web.bind.annotation.RequestMapping; import org.springframework.web.bind.annotation.RequestMethod; import org.springframework.web.bind.annotation.RequestParam; import service.PersonService; import domain.Person; /** * Handles and retrieves person request */ @Controller @RequestMapping("/main") public class MainController { protected static Logger logger = Logger.getLogger("controller"); @Resource(name = "personService") private PersonService personService; /** * Handles and retrieves all persons and show it in a JSP page * * @return the name of the JSP page */ @RequestMapping(value = "/persons", method = RequestMethod.GET) public String getPersons(Model model) { logger.debug("Received request to show all persons"); // Retrieve all persons by delegating the call to PersonService List<Person> persons = personService.getAll(); // Attach persons to the Model model.addAttribute("persons", persons); // This will resolve to /WEB-INF/jsp/personspage.jsp return "personspage"; } /** * Retrieves the add page * * @return the name of the JSP page */ @RequestMapping(value = "/persons/add", method = RequestMethod.GET) public String getAdd(Model model) { logger.debug("Received request to show add page"); // Create new Person and add to model // This is the formBackingOBject model.addAttribute("personAttribute", new Person()); // This will resolve to /WEB-INF/jsp/addpage.jsp return "addpage"; } /** * Adds a new person by delegating the processing to PersonService.

Guidance

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.
