spring integration 4.1.4. exception : Unable to locate NamespaceHandler for XML schema

Question

I used spring 2.2. and I have recently upgraded to spring 4.1.4.

My project uses the the following application context:

<?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:context="http://www.springframework.org/schema/context"
       xmlns:int="http://www.springframework.org/schema/integration"
       xmlns:int-file="http://www.springframework.org/schema/integration/file"
       xmlns:task="http://www.springframework.org/schema/task"
       xsi:schemaLocation="http://www.springframework.org/schema/beans
        http://www.springframework.org/schema/beans/spring-beans.xsd
        http://www.springframework.org/schema/task 
        http://www.springframework.org/schema/task/spring-task.xsd
        http://www.springframework.org/schema/context              
        http://www.springframework.org/schema/context/spring-context.xsd
        http://www.springframework.org/schema/integration
        classpath:com/alu/motive/smdm/mediation/process/orchestration/activity/spring-integration.xsd">

Note that I am using classpath to refer to the spring integration xsd file as I did not see the spring.shemas in the spring jar file. When I run the application, I receive the following exception: Exception in thread "Thread-8" org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/integration]

Likely, the root cause comes from the absence of the spring.handlers file. Could you tell me what is the best way to solve my issues?

Unfortunately your namespace config isn't full. You declare int and int-file nls, bu don't declare their schemaLocation. If you really are interested in the Spring Integration and have appropriate jars in the classpath, please, add their schemaLocation:

http://www.springframework.org/schema/integration/file http://www.springframework.org/schema/integration/file/spring-integration-file.xsd
http://www.springframework.org/schema/integration http://www.springframework.org/schema/integration/spring-integration.xsd
