[JBoss-user] [JBoss Seam] - Re: @In vs. @EJB

2006-07-10 Thread bambata
So, in case of a stateless Bean Seam uses for Injection via @In a common
 JNDI-lookup to the containers registry(ENC) ?

[JBoss-user] [JBoss Seam] - @In vs. @EJB

2006-07-01 Thread bambata
Hello,

when I have a stateless service-bean which contains several stateless 
dao-beans, where is the difference between the two relevant annotations @In and 
@EJB for injecting the dao.
Is it correct that @EJB means the EJB-Container manages and injects the dao and 
that @In means the Seam-framework manages and injects the dao?
Or if I use @In does Seam recognise the dao as a stateless EJB3.0-Bean and 
delegates the Injection to the EJB-Container?

thanks in advance

hans

[JBoss-user] [JBoss Seam] - SFSB: Seam-State / EJB3Container-State

2006-07-01 Thread bambata
Hi,
the Seam-reference documentation says, Seam provides deep integration with EJB 
3.0 and fully supports EJB3.0 session-beans.

It is clear that Seam manages state of components that are put into the 
seam-context using @Out and fetched from the context using @In. 
However if I have a stateful session bean, which contains components using 
@In/@Out, and also components without using @In/Out which are only used within 
the stateful bean but not in the weblayer. My question is, does seam manage the 
state of these components not using @In/@Out or is this complete responsibility 
of the EJB3-container? 

My 2nd question: The serverside state of the components using @In/@Out is also 
managed by the EJB container, right? I understand that the container isn´t able 
to manage the state between client and server(which is seams task), however, if 
the container saves the state of seam components using @In/@Out then the state 
is partly duplicated because its in the seam-context and in the ejb-container. 
Do I understand this correct?

thanks

hans

Ok, and state-management of [EMAIL PROTECTED]/@Out-fields is not subject to 
Seam, right?

[JBoss-user] [JBoss Seam] - Re: SEAM context questions

2006-06-22 Thread bambata
Its better to use the conversation-context, because then you can exactly 
control how long the state exists and you don´t have to remove it manually from 
the context. If you have a long message-list with a lot of data the session 
context is not appropriate. The session-context should be used only for data 
needed for the whole session, like user date for example.

Anyhow, you can access the session-context with:

Contexts.getSessionContext().remove(...);

import org.jboss.seam.contexts.Contexts;

[JBoss-user] [JBoss Seam] - Re: Client-State Saving - which technique is used?

2006-06-21 Thread bambata
Well, the UIViewRoot is the container for all controls on the Page and its the 
root element of the component tree. 
However I actually wanted to know where the data is physically stored. I looked 
into some JSF books and found that client-state-saving puts the state into the 
rendered markup that is sent to the client, usually by using a large hidden 
html-input-field.

So, Seam puts the state information into the JSF ViewRoot Container and then 
delegates the responsibility for state-saving to JSF, and JSF is from that 
point on fully responsible for state-saving, is that correct?

[JBoss-user] [JBoss Seam] - Client-State Saving - which technique is used?

2006-06-20 Thread bambata
Hello,

I am writing my master thesis about Jboss Seam/EJB3/JSF and I am looking for 
some information about how the client-state saving takes place. In the Seam 
reference documentation is written the state is saved within the client 
browser. But where is the information exactly, is it in the cache of the 
browser, in a cookie or perhaps embedded in the html code as encoded 
information? How is that place in the browser accessible?

thanks in advance

hans
