Spring 3.0 - Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/security]

java, maven-2, spring, spring-security

Solution

I needed to add an additional Maven dependency:

    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-config</artifactId>
        <version>3.0.1.RELEASE</version>
    </dependency>

Problem

Any ideas what could be the cause of this? Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/security] ``` org.springframework.web.context.ContextLoader initWebApplicationContext: Context initialization failed org.springframework.beans.factory.parsing.BeanDefinitionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/security] Offending resource: ServletContext resource [/WEB-INF/applicationContext.xml] ``` This is my applicationContext.xml: ``` <?xml version="1.0" encoding="UTF-8"?> <beans:beans xmlns="http://www.springframework.org/schema/security" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:beans="http://www.springframework.org/schema/beans" xmlns:context="http://www.springframework.org/schema/context" xsi:schemaLocation="http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-3.0.xsd http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-3.0.xsd http://www.springframework.org/schema/security http://www.springframework.org/schema/security/spring-security-3.0.xsd"> ... </beans:beans> ``` In my pom.xml I have: ``` <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-core</artifactId> <version>3.0.1.RELEASE</version> </dependency> <dependency> <groupId>org.springframework.security</groupId> <artifactId>spring-security-openid</artifactId> <version>3.0.1.RELEASE</version> </dependency> ```
