HTTP Status 404 with Spring MVC

[Alejandro Barrero]

I created a web application that runs fine in STS, but after I created a war file and installed it in Tomcat I get a 404 error. The web.xml document is:

<?xml version="1.0" encoding="UTF-8"?>
<web-app version="2.5" 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_2_5.xsd">

	</context-param>

	</servlet>
		
	<servlet-mapping>
		<servlet-name>appServlet</servlet-name>

	</servlet-mapping>

</web-app>

I don't know how it can work on STS, because web.xml does not have <welcome-file-list>. For some reason the JSP is in folder views, but STS finds it. I added:

	<welcome-file-list>
		<welcome-file>/views/home.jsp</welcome-file>
	</welcome-file-list>

But I still have the same 404 error.

try to use /* in servlet mapping instead /

Thank you, but that doesn't work.

I did more digging on the Internet and found that I had to have <packaging>war</packaging> in pom.xml, but it is already there. I am totally confused.

[Alejandro Barrero]

STRANGE. You must have

<plugin>
    <groupId>org.apache.tomcat.maven</groupId>
    <artifactId>tomcat7-maven-plugin</artifactId>
    <version>2.2</version>
</plugin>

in pom.xml

so is it working now?
