Hot to modify and refresh context at runtime

[Ciccio17]

Hello everybody,
I'm having some troubles understanding the way I can modify and reload/refresh the context at runtime(without re-deploying my app).

I need to add some bean definition to the context, depending from user behaviour (read: when a user submit a form, i have to add some bean to the application context, depending from user submitted data), then I (suppose) have to refresh the context to get my new beans available for any kind of operation (in detail: scheduling with Quartz).

How can I do that?

At the moment I tried to do something like this:

in my ApplicationContextAware implementing class....

XmlWebApplicationContext ctx = (XmlWebApplicationContext) context; 
System.out.println("bean count before"+ctx.getBeanDefinitionCount());
registerBean(f); //f is my data Object-see below
ctx.refresh();
System.out.println("bean count after"+ctx.getBeanDefinitionCount());
CronTriggerBean c= (CronTriggerBean) ctx.getBean(f.getNome()+"Job");

and here's the registerBean(Fonte f) definition

private void registerBean(Fonte f){
		try {
			XmlWebApplicationContext ctx = (XmlWebApplicationContext) context;
			DefaultListableBeanFactory beanFactory = (DefaultListableBeanFactory) ctx.getBeanFactory();
			BeanDefinitionBuilder simpleTriggerBeanBuilder = BeanDefinitionBuilder.rootBeanDefinition(org.springframework.scheduling.quartz.CronTriggerBean.class);
			simpleTriggerBeanBuilder.addPropertyValue("cronExpression", "0/10 * * * * ?");
			beanFactory.registerBeanDefinition(f.getNome()+"Job",simpleTriggerBeanBuilder.getBeanDefinition());
		}catch(Exception e){e.printStackTrace();}
		
	}

The output is:

bean count before43
bean count after43
org.springframework.beans.factory.NoSuchBeanDefini tionException: No bean named 'ffffffffJob' is defined

-bean count is always the same. Should be incremented by 1, doesn't?
-'ffffffffJob" is the user submitted data

What's wrong with that?
Is this the right way to do what I'm trying to do(modify and refresh the context) ?
Any suggestion?

Thank you in advance.

Regards.
