error as Cannot find the declaration of element 'beans' - spring-mvc

This is my dispatcher servlet. I am getting the error as declaration of beans although I have added the spring.beans.jar.
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:context="http://www.springframework.org/schema/context"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="

<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/WEB-INF/jsp/" />
<property name="suffix" value=".jsp" />
</bean>
</beans>
What am I doing wrong?


A shot in the dark but try this unversioned declaration:
<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"

Try to declare a bean by following;)
<bean id="webContentInterceptor" class="org.springframework.web.servlet.mvc.WebContentInterceptor">
<property name="cacheSeconds" value="0"/>
<property name="useExpiresHeader" value="true"/>
<property name="useCacheControlHeader" value="true"/>

Or add beans namespace xmlns:beans = "http://www.springframework.org/schema/beans" like following;)
<?xml version="1.0" encoding="UTF-8" ?>
<beans xmlns="http://www.springframework.org/schema/beans"

Make sure that the xml schema of you xml file is corresponding to your spring version, so for spring 3.0 should be something like
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

http://www.springframework.org/schema/mvc http://www.springframework.org/schema/mvc/spring-mvc-3.0.xsd">
the stacktrace issue saying
Configuration problem: Cannot locate BeanDefinitionParser for element [resources] Offending resource: ServletContext resource [/WEB-INF/spring-servlet.xml]
appears as though you're having a mistmatch between your jars and the included schema
UPDATE
Better yet, include the XSDs without the version, that will match the schema's with the schemas you're using in your app. So something like
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"

Issue with accessing css, js files in Dynamic Web Project

I have an issue trying to access css & js files from a jsp file (WEB-INF/jsp/index.jsp). I read through some of the similar issue faced by other people at Stack Overflow.
I added this line of code to my SpringMVCProj-servlet.xml and it made things a lot more complicated.
