Closed 5 years ago.
Although I have tried numerous ways to solve this problem, but did not succeed yet.
I am getting this error "cvc-elt.1: Cannot find the declaration of element 'beans'" in "dispatcher-servlet.xml" file.
<?xml version="1.0" encoding="UTF-8"?>

Can someone look in to my problem.

Answer 1

You're using an unprefixed name for the beans element, but you've bound the relevant namespace to a prefix
xmlns:beans="http://www.springframework.org/schema/beans"
You probably want to use a default namespace declaration xmlns="..." instead of xmlns:beans="...", or the alternative would be to prefix the element name
<beans:beans ...>

Answer 2

change xmlns:beans="http://www.springframework.org/schema/beans" in xmlns="http://www.springframework.org/schema/beans"
<?xml version="1.0" encoding="UTF-8"?>
<beans xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:context="http://www.springframework.org/schema/context"
xmlns="http://www.springframework.org/schema/beans"
xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd">
<context:component-scan base-package="com.b2b.controller" />
</beans>
