Oracle ADF

[deniss.parhomenko]

Hi

Is it possible to use Oracle ADF with Seam instead of myfaces ?

[jameswoodward]

I think this question should be "Is it possible to use Oracle ADF Faces with Seam". You still need an implementation of JSF (in this case MyFaces).

I am using ADF Faces EA19, MyFaces 1.1.0 on JBoss 4.0.3. I'm trying to replace my glue code with Seam, but not having much luck.

It looks like Seam doesn't like ADF, I think this is due to both ADF and Seam defining a PhaseListener and VariableResolver. Can someone confirm if this is the case?

Is it possible to remove the PhaseListener and/or VariableResolver from ADF?

The exception I get when trying to convert the Registration Demo to use ADF is:

This stack trace seems to show that the ADF variable resolver is being used instead of Seam's. Most certainly, Seam needs its variable resolver :)

[jameswoodward]

It looks like the problem lies in the adf-faces-impl-ea19.jar.

There is a meta-inf/faces.config.xml file in the jar, which contains:

<application>
 <view-handler>oracle.adfinternal.view.faces.application.ViewHandlerImpl</view-handler>
 <state-manager>oracle.adfinternal.view.faces.application.StateManagerImpl</state-manager>
 <navigation-handler>oracle.adfinternal.view.faces.application.NavigationHandlerImpl</navigation-handler>
 <variable-resolver>oracle.adfinternal.view.faces.el.AdfFacesVariableResolver</variable-resolver>
 </application>

 <lifecycle>
 <phase-listener>oracle.adfinternal.view.faces.context.AdfFacesPhaseListener</phase-listener>
 </lifecycle>

I'm guessing that this is to provide the processScope functionality.

I wonder if this variable resolver can be commented out as we need to use Seam's one?

Hi all,

I'm building a simple web app using ADF EA19, Seam, and JSF RI ( not Myfaces ). So far, I haven't any problem, ... yet. This is just a simple web app.

If you ask the ADF developers, they recommend referencing your processScope variables by #{processScope.varName} to avoid conflicts with other variable resolvers.

Actually, both JSF parts (ADF and Seam) are properly written, since ADF loads from the Jar, you just need to make sure that your faces-config.xml in your application follows the guidlines here:

HI all,

So far my attempt to use some of ADF component was succesful.
Except, when I tried the <af:table> component :

<af:table value="#{projectAction.findAll}" var="row" rows="10"
 binding="#{projectAction.table}" >

The backing bean associate is as follows :

@LoggedIn
@Name("projectAction")
public class ProjectAction {
 ...
 @Out(required=false)
 private List<Project> listProject;

 @In(create=true)
 private Session hibernateSession;

 public List<Project> getFindAll() {
 log.info("=== getFindAll ... ");
 if (listProject == null)
 buildListProject();
 return listProject;
 }

 public void setFindAll(List<Project> prj) {
 this.listProject = prj;
 }

 @SuppressWarnings("unchecked")
 public void buildListProject() {
 log.info("=== buildListProject ... ");
 List<Project> list = null;
 try {
 list = hibernateSession.createCriteria(Project.class)
 .addOrder(Order.asc("projectName"))
 .list();
 log.info("=== buildListProject has : " + list.size());
 } catch (HibernateException ex) {
 throw new SeamTestException("HibernateException raised : " + ex.toString());
 }
 setFindAll(list);
 }

 public UIXTable getTable() {
 return table;
 }

 public void setTable(UIXTable table) {
 this.table = table;
 }
 ...
}

Now, every time I deploy my war, and go to that page, I got the following error :

00:25:02,734 DEBUG [org.jboss.seam.contexts.Contexts] found in application context: org.jboss.seam.core.manager.component

I do have a getter/setter for findAll, but why it's still complaining ?
Or is it something else ?

Any help would be very grateful.

Thanks,
nusa

[deniss.parhomenko]

put

@Intercept(InterceptionType.ALWAYS)

to class declaration
bet then, i think, you receive another exception related to binding="#{projectAction.table}".

[gavin.king]

No, if he puts @Intercept(InterceptionType.ALWAYS) , I think it will work.

[nusa]

No, if he puts @Intercept(InterceptionType.ALWAYS) , I think it will work.

No Gavin, Deniss is right.
I got :

12:33:41,659 DEBUG [javax.faces.el.PropertyResolver] Error getting property 'table' from bean of type example.action.ProjectAction$$EnhancerByCGLIB$$f7a9cd13: org.jboss.seam.RequiredException: In attribute requires value for component: project

Any more sugggestions / help ?
Thanks

[deniss.parhomenko]

Try to define another bean

@Name("otherBean")
@Scope(org.jboss.seam.ScopeType.EVENT)
public class OtherBean{
 private ... table;
 public setTable(... table)
 public ... getTable()

then in your jsp put

binding="#{otherBean.table}"

this code gets table binding:

Contexts.getEventContext().get("otherBean");

[nusa]

Thanks Deniss,

Yes that works, except that I got a ClassCastException with this code:

UIXTable table = (UIXTable)Contexts.getEventContext().get("otherBean");

The 'otherBena' is defined as :

@Name("otherBean")
@Scope(org.jboss.seam.ScopeType.EVENT)
public class OtherBean {
 private UIXTable table;
 public setTable(UIXTable table)
 public UIXTable getTable()
 ...
}

Any idea ?

Thanks.

[deniss.parhomenko]

Try to put Object instead of UIXTable, and check which class are setted(use debugger ot System.out)

[jameswoodward]

Here is how I have modified the Registration sample, but I still get the above error. What else do I need to do/have I done wrong?
