Error

The web application fails to start due to the following error

org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/mvc]

Solution

You need to have the JAR file: spring-webmvc-3.1.0.RELEASE.jar (or a newer version if available – check from here) in your web application classpath. If you are using Maven, simply add the following to your dependencies.

<dependency>  <groupId>org.springframework</groupId>  <artifactId>spring-webmvc</artifactId>  <version>3.1.0.RELEASE</version></dependency>

Make sure you also have the following dependencies in your classpath, as otherwise the web application may not start due to missing classes:

• Spring Web JAR file: spring-web-3.1.0.RELEASE.jar

  <dependency>  <groupId>org.springframework</groupId>  <artifactId>spring-web</artifactId>  <version>3.1.0.RELEASE</version></dependency>

• Hibernate Validator JAR file: hibernate-validator-4.3.0.Final.jar

  <dependency>  <groupId>org.hibernate</groupId>  <artifactId>hibernate-validator-annotation-processor</artifactId>  <version>4.3.0.Final</version></dependency>
