Java Spring address of page - spring

Question

I am really confused how does the address of my spring application come from.
I followed the tutorial, but now I am trying to change the address, but I can't find the spot.
At the moment address is this : http://localhost:8080/HelloWorld/
Where can I change HelloWorld to something else?
I will provide you with any code you need. I have two conf files : web.xml, spring-servlet.xml, but there is nothing in them that contains HelloWorld.
<?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:p="http://www.springframework.org/schema/p"

xsi:schemaLocation="http://www.springframework.org/schema/beans

http://www.springframework.org/schema/context
http://www.springframework.org/schema/context/spring-context-3.0.xsd">
<context:component-scan base-package="hello.spring3.controller" />
<bean id="viewResolver"

<property name="viewClass"
value="org.springframework.web.servlet.view.JstlView"/>
<property name="prefix" value="/WEB-INF/jsp/"/>
<property name="suffix" value=".jsp" />
</bean>
</beans>
and web.xml
<?xml version="1.0" encoding="UTF-8"?>

Answer 1

Actually this is not issue unless you deploy it on production environament.
When you deploy it there you should create new HOST in TOMCAT_HOME/conf/server.xml file
it should look something like:
<Host name="www.mysite.com" appBase="www"
unpackWARs="true" autoDeploy="true"
xmlValidation="false" xmlNamespaceAware="false">
</Host>
Second option is to deploy your war file in ROOT directory, but in my opinion the first option is more suitable.
Update: No problem, If you are using eclipse, please click right mouse button on your project, Select Properties - > Web Project Settings.
and change name of your "HelloWorld" directory.

Answer 2

It's the name of your war file.
