Hi !
I use jsf-spring ( http://jsf-spring.sourceforge.net/ ) and it works
very well. See the quickstart tutorial on their homepage, very easy to
setup.
Besides the spring integration, maybe you should rethink your design ?
Use somthing like acegi security to perform authentification and
authorization instead of passing Session objects to the business layer...
At least consider wrapping the info you need (user id and roles) in an
object, instead of passing the session object...
As far as I remember (after quite some time using frameworks I guess
I've lost some basics :-)) there's no need to store the user's details
in the session ? Everything should be there, at least if you use
container (or tomcat) based auth ?
Hope that helps,
Tom

Hi Kito
Thanks for quick response. The reason Spring beans need direct access to
session object is to perform some business logic based on userId and user
Roles stored in session object. Hence the need to pass the session object
>from JSF to Spring. As you suggested i already implemented injecting Spring
beans into JSF managed beans via managed-property in faces-config.xml. And i
am able to successfully call Spring bean method i.e.
getUserSession(userSession) to pass the session object to Spring layer. But
this call is limited to single Spring Bean. How if i wanna use same session
object in other spring beans .
Here are the limitations of this approach
- Redundant code in each Backing bean calling Spring bean to pass session
object
- Is it recommended to pass HttpSession object to business (Spring) layer
- Is it recommended to store userId and user Role in HttpSession object
inside JSF Backing Bean. My requirement is all my Spring beans perform
business logic based on userId and user Roles
- The reason i put question mark on HttpSession object is even within JSF
backing beans session is lost. For example i construct session object in
LoginBean and when i try to retrieve session in other backing bean it
returns null. So i have to do something like this in the constructor of
backing bean
if(userSession == null){
System.out.println("Inside Manuf Constructor userSession");
userSession =
(HttpSession)
FacesContext.getCurrentInstance().getExternalContext()
.getSession(true);
Object sess = userSession.getAttribute("userId");
System.out.println("userId in Session="+sess.toString());
- Also the constructor of backing bean doesnt allow me to make a call Spring
bean and results in Null Pointer Exception. So not sure where exactly in the
backing bean i should make a call to getUserSession() method of Spring. For
test purposes i am making this call from register() method of backing bean
Overall i didnt have good success stories to share with by adopting this
approach. Any pointers/suggestions will be highly appreciated

Hello Bansi,
You can inject Spring beans into your JSF managed beans via the Spring
DelegatingVariableResolver. Given that, you should be able to call your
Spring bean methods and pass in the appropriate parameters. Why do your
Spring beans need direct access to the session?

Subject: How to Share Session between JSF(MyFaces) and Spring
Hi Gurus
Could you please tell me
What are the best practices to pass Session object from JSF to Spring.
For
example lets say LoginBean in JSF has to store userId and userRole in
Session object and then pass Session object to Spring Layer so that it
can
be accessible by any spring bean
- Do you recommend using Httpsession?
- Does OpenSessionInViewFilter provides a mechanism to store userId &
userRole in session & then pass it onto spring layer
OR
- Is their any other mechanism that you would recommend for storing
userId &
userRoles into Session object at JSF Layer and then retrieve the same
Session object at Spring layer so that it can be accessible by an
spring
bean
Any pointers/suggestions will be highly appreciated

Bansi
