Spring, JMS - Unable to locate Spring NamespaceHandler for XML schema namespace - spring

Question

Over and over I'm getting this error:
10:37:21,270 ERROR DispatcherServlet:466 - Context initialization failed
org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://activemq.apache.org/schema/core]
Offending resource: ServletContext resource [/WEB-INF/mvc-dispatcher-servlet.xml]
I've tried many pom.xml and spring configurations, but none of them worked so far.
Here are dependencies in my pom.xml:
<dependencies>
<dependency>
<groupId>org.springframework</groupId>
<artifactId>spring-core</artifactId>
<version>${spring.version}</version>
</dependency>
<dependency>

</dependency>
<dependency>
<groupId>com.networkwatcher</groupId>
<artifactId>NetworkWatcherJMS</artifactId>

</dependency>
</dependencies>
And here is my servlet config:
<beans xmlns="http://www.springframework.org/schema/beans"
xmlns:amq="http://activemq.apache.org/schema/core"
xmlns:jms="http://www.springframework.org/schema/jms"

</jms:listener-container>
<bean class="org.springframework.web.servlet.view.InternalResourceViewResolver">
<property name="prefix" value="/Views/"/>
<property name="suffix" value=".jsp"/>
</bean>
Could anyone tell we what is wrong in here and how to fix it?

Answer 1

You are missing the entry for activemq-spring
<dependency>
<groupId>org.apache.activemq</groupId>
<artifactId>activemq-spring</artifactId>
<version>5.8.0</version>
</dependency>

Answer 2

I don't know why, but maven didn't download dependencies, however they were specified in pom.xml. Making mvn clean from command prompt solved the problem.
