Simple Spring configuration

Spring configuration for use of a simple transaction manager (non XA). The data source must be defined in a JNDI repository (Tomcat in my case).

To start automatically the Spring Ccontext, add in your web.xml:

    <listener>
        <listener-class>org.springframework.web.context.ContextLoaderListener</listener-class>
    </listener>
