Why does my web page expire?

Why don't I see the home page in the browser in the following Spring web app?

• Here is the controller that I use @Controller public class ProjectController { @Autowired private ProjectService ProjectService; @Autowired public ProjectController(ProjectService ProjectService){ this.ProjectService = ProjectService; } @RequestMapping({"/","/find"}) public String getPersonList(@RequestParam("regNo") String regNo, ModelMap model) { model.addAttribute("ProjectList", ProjectService.getStudentProject(regNo)); return "find"; } } I have a page called find.jsp under WEB-INF/jsp folder. But when I hit localhost:8080/find I get HTTP status 400 error Following is my dispatcher-servlet.xml where I have made the mappings <?xml version="1.0" encoding="UTF-8"?> <beans xmlns="Index of /schema/beans" xmlns:xsi="Page on w3.org" xmlns:context="Index of /schema/context" xmlns:p="Page on springframework.org" xmlns:mvc="Index of /schema/mvc" xmlns:beans="Index of /beans" xsi:schemaLocation="Page on springframework.org Page on springframework.org Page on springframework.org Page on springframework.org"> <mvc:annotation-driven/> <context:component-scan base-package="com.MyAppName.www" /> <!-- Factory bean that creates the Mongo instance --> <bean id="mongo" class="org.springframework.data.mongodb.core.MongoFactoryBean"> <property name="host" value="localhost" /> </bean> <!-- MongoTemplate for connecting and quering the documents in the database --> <bean id="mongoTemplate" class="org.springframework.data.mongodb.core.MongoTemplate"> <constructor-arg name="mongo" ref="mongo" /> <constructor-arg name="databaseName" value="MyApp" /> </bean> <!-- Use this post processor to translate any MongoExceptions thrown in @Repository annotated classes --> <bean class="org.springframework.dao.annotation.PersistenceExceptionTranslationPostProcessor" /> <bean id="jspViewResolver" class="org.springframework.web.servlet.view.InternalResourceViewResolver" p:prefix="/WEB-INF/jsp" p:suffix=".jsp" /> </beans> This is how web.xml looks <web-app xmlns="Java EE: XML Schemas for Java EE Deployment Descriptors" xmlns:xsi="Page on w3.org" xsi:schemaLocation="Java EE: XML Schemas for Java EE Deployment Descriptors Page on sun.com" version="2.5"> <display-name>Spring With MongoDB Web Application</display-name> <servlet> <servlet-name>dispatcher</servlet-name> <servlet-class>org.springframework.web.servlet.DispatcherServlet</servlet-class> <load-on-startup>1</load-on-startup> </servlet> <servlet-mapping> <servlet-name>dispatcher</servlet-name> <url-pattern>/</url-pattern> </servlet-mapping> <context-param> <param-name>contextConfigLocation</param-name> <param-value>/WEB-INF/dispatcher-servlet.xml</param-value> </context-param> <listener> <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class> </listener> <welcome-file-list> <welcome-file>/WEB-INF/find.jsp</welcome-file> </welcome-file-list> </web-app> [/code/ This is how my server log looks like. I am using Tomcat 7.0 [code] The url I use is localhost:8080/find.jsp and I get 404 error. [/code]

• Answer:

  Following were the issues and corresponding solutions 1) The project doesn't have webapp folder. When you create a project using maven be mindful. You can follow the steps mentioned here http://blog.manishchhabra.com/2013/04/spring-data-mongodb-example-with-spring-mvc-3-2/ 2) Make sure you have the jsp files inside theWEB-INF folder and the path is properly mentioned all across the application. I got several other errors in between, but all those could be solved if you search in google and select the first stackoverflow result.
