/**
 * This ejb3 bean does not implement the content service.
 * Repository services have been implemented through spring
 * The sole purpose of this class is to expose the content service as an ejb3 bean. 
 * It acquires the content service from JNDI where we have deployed a shared spring context with the beans that implement the repository services
 * Through the @Resource annotation we get the shared spring context from the JNDI and then we get the content service bean from the spring context.
 * The methods then use the spring bean to call the required functionality.
 * Another option would be to not separately deploy the spring context but have the ejb3 bean to bootstrap the spring and get the required beans.
 * This can be done through the following interceptor: @Interceptors(SpringBeanAutowiringInterceptor.class) and a refParentContext.xml file in repository module classpath that loads the 
 * spring bean files under a parent context.
 * We have chosen no to do so in order to allow applications to access the repository in both ways. Either as spring service beans or as ejb3 service beans.
