BasicDataSource not finding postgresql or postgis jdbc drivers

I'm trying to add a BasicDataSource to a new LocalContainerEntityManagerFactoryBean. When I create the new dataSource like so:

<bean id="dataSource" class="org.apache.commons.dbcp.BasicDataSource" destroy-method="close">
    <property name="driverClassName" value="org.postgresql.Driver" />
    <property name="url" value="jdbc:http://postgresql_postGISlocalhost:5432/database" />
    <property name="username" value="XXXXX" />
    <property name="password" value="XXXXX" />
</bean>

And add it to the entitiyManagerFactory

<bean id="entityManagerFactory" class="org.springframework.orm.jpa.LocalContainerEntityManagerFactoryBean">
    <property name="dataSource" ref="dataSource"/>
</bean>

The error I'm getting is that it's can't find the JDBC driver:

[org.hibernate.engine.jdbc.internal.JdbcServicesImpl.configure] HHH000342: Could not obtain connection to query metadata : Cannot load JDBC driver class 'org.postgresql.Driver'

I have the jar being loaded via maven:

<dependency>
    <groupId>org.postgresql</groupId>
    <artifactId>postgresql</artifactId>
    <version>9.3-1103-jdbc3</version>
</dependency>

and mavens added to my classpath

<classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
    <attributes>
        <attribute name="maven.pomderived" value="true"/>
        <attribute name="org.eclipse.jst.component.dependency" value="/WEB-INF/lib"/>
    </attributes>
</classpathentry>

So I'm wondering what am I missing? I can see that the driver is available from the maven dependencies library, but it never finds it when starting up. Any ideas would be much appreciated.
