public class LocalSlsbInvokerInterceptor extends AbstractSlsbInvokerInterceptor
Caches the home object, since a local EJB home can never go stale.
See JndiObjectLocator for info on
how to specify the JNDI location of the target EJB.
In a bean container, this class is normally best used as a singleton. However, if that bean container pre-instantiates singletons (as do the XML ApplicationContext variants) you may have a problem if the bean container is loaded before the EJB container loads the target EJB. That is because by default the JNDI lookup will be performed in the init method of this class and cached, but the EJB will not have been bound at the target location yet. The best solution is to set the lookupHomeOnStartup property to false, in which case the home will be fetched on first access to the EJB. (This flag is only true by default for backwards compatibility reasons).

Alternatively, override getSessionBeanInstance() and
releaseSessionBeanInstance(javax.ejb.EJBLocalObject) to change EJB instance creation,
for example to hold a single shared EJB instance.
