JSF and dependency injection
Hello..
I'd juste understand how JSF IOC container works..i tried to do something
like ..
<managed-bean>
<managed-bean-name>person</managed-bean-name>
<managed-bean-class>x.y.Person</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
<managed-property>
<property-name>adress</property-name>
<property-class>x.y.z.Adress</property-class>
<value>#{adress}</value>
</managed-property>
</managed-bean>
<managed-bean>
<managed-bean-name>adress</managed-bean-name>
<managed-bean-class>x.y.z.Adress</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
<managed-property>
<property-name>..</property-name>
<property-class>...</property-class>
<value>#{adress}</value>
</managed-property>
</managed-bean>
On the Person bean when I set adress value, it's not the same instance of
the adress on the session..I should do #{person.adress.xx} to get adress
values on the jsf pages..
how can i share identical instance for the bean..???
using annotation and seam we can write on the Person bean:
@In("adress")
private Adress adress;
thanks ..

Hmmmm... There really should be only one instance of each (Person and
Address) in the session. Have you tested this to make sure you're not
setting that value somewhere else?
As a side note, it'd probably make more sense to make Address a "none"
scoped object and just access it through the Person object. I think it makes
sense to keep the smallest number of objects in any given scope.

hii
I dont use seam for this project..
I tested sessionScope,on the debug mode, the adress bean values are not nul;
but, on the JSF page the EL expression #{adress.xxxx}, do not display
anything. it seems that it's not the same instance of bean..

Re: JSF and dependency injection
Posted by "Ulath (AKA: Murat HAZER)" <mu...@gmail.com>.
could you try to add sessionScope.address ?
<managed-bean>
<managed-bean-name>person</managed-bean-name>
<managed-bean-class>x.y.Person</managed-bean-class>
<managed-bean-scope>session</managed-bean-scope>
<managed-property>
<property-name>adress</property-name>
<property-class>x.y.z.Adress</property-class>
<value>#{sessionScope.adress}</value>
</managed-property>
</managed-bean>
and if you use seam why do u need bean definitions in faces-config.xml like
this?

Re: JSF and dependency injection

No it's not a singleton,
adress bean is a session bean, and I need to use it one the person bean..I
should have one instance of per session.
the purpose here is to set adress bean properties on the person bean
..using dependency injection..
JSF is an ioC container..so its not necessary to use spring just for that
!!!

I am thinking about understanding that what you need is that the bean person
is a singleton. I believe you need spring with jsf.
