scope=quot;sessionquot; xml, example, problem, simple

amy

I'm trying to run some simple example that use scope=quot;sessionquot;. But it doesnt work. I think with this type of scope each user session create a new bean, but this not work in my example. The controller uses the same bean to all application. What is the problem? I'm using RC2.

Thanks to all

public void setObjetoSessao(ObjetoSessao objetoSessao) {
this.objetoSessao = objetoSessao;
}

@Override
protected ModelAndView handleRequestInternal(fromServletRequest arg0,
fromServletResponse arg1) throws Exception {

objetoSessao.valor++;
HashMap m = new HashMap();
m.put(quot;valorquot;, objetoSessao.valor);

return new ModelAndView(quot;index.jspquot;, m);
}

}Isn't quot;singleton=falsequot; what you are looking for?

In Spring 2.0 that is a new attribute scope. I think this is the correct.

But, if I use singleton=quot;falsequot;, like this:Code:
lt;bean id=quot;objetoSessaoquot; class=quot;ObjetoSessaoquot; singleton=quot;falsequot;/gt;
lt;bean name=quot;/hello.tstquot; class = quot;DependeSessaoquot;gt;  lt;property name=quot;objetoSessaoquot; ref=quot;objetoSessaoquot;/gt;
lt;/beangt;
why this create just 1 time the quot;objetoSessaoquot;?

I tested putting  lt;igt;System.out.println(quot;creating object...quot;)lt;/igt; at constructor, and print it just 1 time !!!!!!Where is my wrong?

i'm also new to spring, so dont bother with me

thinking a little bit, try to set scope=quot;sessionquot;  or singleton=false on the bean named quot;/hello.tstquot; instead of objetoSessao.

thnking like spring, it would just call objectoSessao when creating ref to DependeSessao. I dont know...

Hope i could help... Thus im learning too.

I tested this, but I dont want this. I like that the object quot;DependeSessaoquot; must created 1 time, and the quot;ObjetoSessaoquot; depends on the request.

Adilson

and what error do you get when using scope?
When I'm trying to use a bean from jsf I get

Code:
javax.el.ELException: /view.xhtml:
Error creating bean with name 'abean': Scope 'session' is not active;
nested exception is java.lang.IllegalStateException:
No thread-bound request: use RequestContextFilter
And of course I have

Code:
lt;listenergt;
lt;listener-classgt;
org..web.context.scope.RequestContextListener
lt;/listener-classgt;
lt;/listenergt;There arent message errors. But the ObjetoSessao creates just 1 time.
