Neo4j 2.2.3 ClassNotFoundException: org.neo4j.kernel.impl.transaction.XaDataSourceManager

This is my Maven config for Neo4j:

    <properties>
        <neo4j.version>2.2.3</neo4j.version>
    </properties>

    <!-- neo4j -->
    <dependency>
        <groupId>org.neo4j</groupId>
        <artifactId>neo4j-enterprise</artifactId>
        <version>${neo4j.version}</version>

        <version>${neo4j.version}</version>
    </dependency>

During the application startup I have a following exception:

I can't find where XaDataSourceManager is located.

Xadatasource is present in the neo4j-kernal jar, but with jar version before 2.2.2. Since you are using 2.2.3, you will not find the class in the jar. I think the jar versions you are using are not compatible. Try adding the parent jar and let it reference to the compatible ones.
