Unable to locate Spring NamespaceHandler for XML schema namespace [http://www.springframework.org/schema/data/neo4j]

Question

I am trying to add spring data for neo4j to an existing project. I can't solve the following error.

ERROR: org.springframework.web.context.ContextLoader - 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/data/neo4j]

My pom is rather big, but the neo4j and/or spring data dependencies are below.

<dependency>
    <groupId>org.neo4j</groupId>
    <artifactId>neo4j-kernel</artifactId>
    <version>2.2.3</version>
</dependency>

<dependency>
    <groupId>org.neo4j</groupId>
    <artifactId>neo4j</artifactId>
    <version>2.2.3</version>
</dependency>

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-neo4j</artifactId>
    <version>3.3.2.RELEASE</version>
</dependency>

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-neo4j-tx</artifactId>
    <version>3.3.2.RELEASE</version>
</dependency>

<dependency>
    <groupId>org.springframework.data</groupId>
    <artifactId>spring-data-neo4j-rest</artifactId>
    <version>3.3.2.RELEASE</version>
</dependency>

The app-confiv.xml contains the namespace definition and the bean instantiation:

<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:jdbc="http://www.springframework.org/schema/jdbc"
xmlns:jee="http://www.springframework.org/schema/jee"
xmlns:neo4j="http://www.springframework.org/schema/data/neo4j"
xsi:schemaLocation="
    http://www.springframework.org/schema/beans http://www.springframework.org/schema/beans/spring-beans-4.0.xsd
    http://www.springframework.org/schema/jee http://www.springframework.org/schema/jee/spring-jee-4.0.xsd
    http://www.springframework.org/schema/jdbc http://www.springframework.org/schema/jdbc/spring-jdbc-4.0.xsd
    http://www.springframework.org/schema/context http://www.springframework.org/schema/context/spring-context-4.0.xsd
    http://www.springframework.org/schema/data/neo4j http://www.springframework.org/schema/data/neo4j/spring-neo4j-3.0.xsd
    ">

<neo4j:config graphDatabaseService="graphDatabaseService" base-package="my.example.package.model"/>
<neo4j:repositories base-package="my.example.package.repository"/>  

<bean id="graphDatabaseService" class="org.neo4j.rest.graphdb.CypherRestGraphDatabase">
   <constructor-arg index="0" value="http://localhost:7474/db/data" />
</bean>

Looking at similar questions it seems that there is a dependency missing that causes this error. However, I could not figure out which dependency is missing neither how to spot the missing one in the other cases.

There is no `spring-data-neo4j-tx` anymore in 3.3.2. I would just add `spring-data-neo4j-rest:3.3.2` — Michael Hunger, Aug 06 '15 at 20:24
I have gotten past this error before seeing your comment by changing the spring data version from `3.3.2` to `3.3.1`. I now tried to remove the `spring-data-neo4j-tx` and I didn't get the error back even after upgrading to `3.3.2`. I'm not sure if it was the tx dependency or a maven/eclipse issue, thus +1 on your comment instead of asking to post it in a reply which I could accept. — ilinca, Aug 07 '15 at 13:14

Remove the version here:

http://www.springframework.org/schema/data/neo4j/spring-neo4j-3.0.xsd

that one was probably removed (outdated) you can either leave the version off or use 3.2 or perhaps 3.3

I had already tried that. 2.0, 3.0, 3.2 or 3.3 neither made any change with respect to the error I get. – ilinca Aug 07 '15 at 08:39
