    Development using Seam 3 in a large size project

    Jignesh Patel Newbie

      I am going to architect a large size project and because of the integration complexity required for the project, I inclined to use Seam framework. But before I finalize the approach I have few questions if JBoss team can answer them then it will be great.
      •     When will we have stable version of Seam3?


      •     We have complex requirement to manage Role based Authorization. How much support seam provides for the same?


      •     Integration with SOAP based web services?


      •     Support for creating and managing workflows?


      •     I know Seam is using java.util.logging will that be sufficient to support complex audiability requirement.


      •     At this time then intention to use JBoss however it may be possible we end using WAS. In that scenario Seam framework is equally efficient?

          While doing more research I found that Shane has following comment for Seam3 authorization functionality. However if Seam 3 is not going to be stable in few weeks we may not able to use Seam3. In that how Seam2.2 can provide same feature.
          Unified authorization architecture - in Seam, authorization checks are performed in a singular manner.  The Identity.hasPermission() method allows for a permission check to be carried out for the current user against multiple PermissionResolver implementations.  We have implementations for Drools (rule-based) and for persistent permissions (ACL-based).  A single permission check will invoke all registered PermissionResolver implementations to determine whether a user has the necessary privileges to execute a secured operation.

            Just wondering if you are aware that a relevant part of the JEE 6 infrastructure is not final 'in a few weeks'?


            As Seam 3 is based on Weld / CDI (which is final) and ships in separate modules, I would not expect too many problems there. Also: With CDI-SPI your are able to hack yourself into Javee EE 6, which can be an option for almost everything...


            The real issue might be your infrastructure / dependend libraries:


            Speaking of today, JBoss AS 6 has some major issues open and Richfaces 4 isn't final before the end of the year.


            Right now I'm on a stack with some Seam 3 modules, a JBoss AS Nightly Build and Primefaces.


            Most problems arise around JBoss AS and ... Eclipse

              Thanks Jan. Based on information you have provided it makes sense not to take risk of using Seam3 when containers are not ready.


              At present we are moving with WAS. I am not sure about the version at this time but we are going to use Hibernate. When I tried to find out deployment specification I found following chaper http://docs.jboss.org/seam/2.2.1.CR1/reference/en-US/html/websphere.html which talks about deploying with EJBs however I don't see any specification for deployment with Hibernate. Thogh there is a sample in 2.2.1 about deploying hibernate with WAS6.
