Jboss Seam: Enabling Debug page on WebLogic 10.3.2 (11g)

Question

SKIP TO UPDATE 3

I want to enable the Seam debug page on Weblogic 10.3.2 (11g). So, I have done the following:

I have the jboss-seam and jbo

Answer 1

You get the following exception

No phase id bound to current thread (make sure you do not have two SeamPhaseListener instances installed)

But you said you have installed an ejb and web maven project. Maybe both includes a SeamPhaseListener when you deploy your application. It, maybe, explains why you get your exception (Two SeamPhaseListener instances installed).

My advice is (And if you want to avoid a lot of headache)

Always generate your project by using Seam-gem

See here why

A nice article, besides Seam in Action book, about JSF/Seam can be found here

Added to original answer

See what Seam in Action book talks about it

In Seam 2.0, the Seam phase listener is declared in a facesconfig.xml descriptor that is included in the core Seam JAR file, jboss-seam.jar. Thus, the phase listener is available as soon as you include this JAR file in your application.

So, you do not have to worry about SeamPhaseListener. Seam will.

UPDATE

First of all, you have a ear application. Before going on

1º Each EJB and war module should be declared in application.xml (The file that describes your ear)

So your ear application should looks like this one (Let's call your ear application pureCharger)

pureCharger.ear

    META-INF
        application.xml
    pureCharger-ejb.jar
        META-INF
            ejb-jar.xml
            persistence.xml
        lib
            // libraries ONLY USED by your EJB module goes here
    pureCharger-war.war
        WEB-INF
            web.xml
            components.xml
            faces-config.xml
            pages.xml
        lib
            // Here is what you want
            jboss-seam-debug.jar 
            jboss-seam-ui.jar
            jsf-facelets.jar
            // other libraries ONLY USED by your war module goes here
    jboss-seam.jar
    lib
        // JBoss Expression Language is used by both EJB and war module
        jboss-el.jar
        // libraries SHARED by all of your modules goes here

ejb-jar.xml is shown as follows (It enables @In-jection by your EJB components)

    
        
            org.jboss.seam.ejb.SeamInterceptor
        
    
    
        
            *
            org.jboss.seam.ejb.SeamInterceptor
        
    

2º jboss-seam.jar is an EJB module

So it should also be declared in application.xml file. And more, as said above, you do not have to define SeamPhaseListener because of jboss-seam.jar includes SeamPhaseListener. So avoid to see this nice message

Two SeamPhaseListener instances installed

So your ear application.xml should looks like this one

    pureCharger
    
        pureCharger-ejb.jar
    
    
        jboss-seam.jar
    
    
        
            pureCharger-war.war
            pureCharger
        
    

ok. Let's go

3º You want to enable debug page

The Seam debug page will be available if this jar is deployed in WEB-INF/lib, along with the Facelets, and if you set the debug property of the init component

So your components.xml should looks like this one

See as shown above i have defined global JNDI address (I suppose you are using JBoss and your ear application is called pureCharger) in order to Seam retrieve its EJB component

And finally, our web.xml file

    
        facelets.DEVELOPMENT
        true
    
    
        javax.faces.DEFAULT_SUFFIX
        .xhtml
    
    
        javax.faces.STATE_SAVING_METHOD
        server
    
    
    
        Seam Filter
        org.jboss.seam.servlet.SeamFilter
    
    
        Seam Filter
        /*
    
    
    
        org.jboss.seam.servlet.SeamListener
    
    
        Faces Servlet
        javax.faces.webapp.FacesServlet
    
    
        Faces Servlet
        *.xhtml
    
    
    
        30
    

And our faces-config.xml

    
        en
        en
    
    com.sun.facelets.FaceletViewHandler
    
        XX.XXXX.XXX.prs.web.messages.messages
        msgs
    
    
        XX.XXXX.XXX.prs.web.messages.validation
        val
    

A couple of notes

You do not need to declare org.jboss.seam.el.SeamELResolver in faces-config.xml because it is bundled with jboss-seam.jar.

Now, what is missed ?

We need to call our debug page (Do not forget starting up JBoss and deploy your ear application)

http://127.0.0.1:8080/pureCharger/debug.xhtml

And again

If you really want to avoid a lot of headache, use seam-gem

UPDATE

Is your ear project AS SHOWN ABOVE ??? MAKE SURE your war lib folder DOES NOT CONTAIN any jboss-seam.jar file. You said

I opened the .ear and the following jboss jars are in:

• jboss-seam-debug-2.2.0.GA.jar (wrong) It must be placed inside war file WEB-INF/lib folder
• jboss-el-1.0_02.CR4.jar (wrong) It must be placed inside ear file lib folder
• jboss-seam-2.2.0.GA.jar (right) But it must be declared in ear META-INF/application.xml file
