Remove the cached session bean instance, if necessary.

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 component instance.

 protected Object getSessionBeanInstance() throws NamingException, InvocationTargetException 
{
		if (this.cacheSessionBean) {
			synchronized (this.beanInstanceMonitor) {
				if (this.beanInstance == null) {
					this.beanInstance = newSessionBeanInstance();
				}
				return this.beanInstance;
			}
		}
		else {
			return newSessionBeanInstance();
		}
}

Return an EJB component instance to delegate the call to.

The default implementation delegates to #newSessionBeanInstance .

 protected  void refreshHome() throws NamingException 
{
		super.refreshHome();
		if (this.cacheSessionBean) {
			synchronized (this.beanInstanceMonitor) {
				this.beanInstance = null;
			}
		}
}

Reset the cached session bean instance, if necessary.

 protected  void releaseSessionBeanInstance(EJBObject ejb) 
{
		if (!this.cacheSessionBean) {
			removeSessionBeanInstance(ejb);
		}
}

Release the given EJB instance.

The default implementation delegates to #removeSessionBeanInstance .

 public  void setCacheSessionBean(boolean cacheSessionBean) 
{
	                                         	 
		this.cacheSessionBean = cacheSessionBean;
}

Set whether to cache the actual session bean object.

Off by default for standard EJB compliance. Turn this flag on to optimize session bean access for servers that are known to allow for caching the actual session bean object.
