Check for EJB3-style home object that serves as EJB component directly.

 protected Object getSessionBeanInstance() throws NamingException, InvocationTargetException 
{

Return an EJB instance to delegate the call to. Default implementation delegates to newSessionBeanInstance.

This implementation "creates" a new EJB instance for each invocation. Can be overridden for custom invocation strategies.

Alternatively, override #getSessionBeanInstance and #releaseSessionBeanInstance to change EJB instance creation, for example to hold a single shared EJB instance.

 protected Object newSessionBeanInstance() throws NamingException, InvocationTargetException 
{
		if (logger.isDebugEnabled()) {
			logger.debug("Trying to create reference to local EJB");
		}
		Object ejbInstance = create();
		if (logger.isDebugEnabled()) {
			logger.debug("Obtained reference to local EJB: " + ejbInstance);
		}
		return ejbInstance;
}

Return a new instance of the stateless session bean. Can be overridden to change the algorithm.

 protected  void releaseSessionBeanInstance(EJBLocalObject ejb) 
{
		removeSessionBeanInstance(ejb);
}

Release the given EJB instance. Default implementation delegates to removeSessionBeanInstance.

 protected  void removeSessionBeanInstance(EJBLocalObject ejb) 
{
		if (ejb != null && !this.homeAsComponent) {
			try {
				ejb.remove();
			}
			catch (Throwable ex) {
				logger.warn("Could not invoke 'remove' on local EJB proxy", ex);
			}
		}
}

Remove the given EJB instance.
