Phase Listener in Subsystem deployed as BTF in Master - jdev 11.1.2.3

Hello:
We are using Subsystems with BTF's that are deployed as ADFLibs. These Subsystem ADFLibs are imported into a Master app and the BTF's are used as a region in the Master.
I tried to create Phase Listener that displays System.out.println msgs in the Subsystem that was then used as a region in the Master app.
But no messages from the Phase Listener appear on the console. What am I missing? Would the Phase Listeners have to be in the Master app?
What if I wanted the Phase Listener of just the subsystem? Is this possible?
Below is the code for adf-settings.xml and java class that implements PagePhaseListener:
<?xml version="1.0" encoding="UTF-8" ?>
<adf-config xmlns="http://xmlns.oracle.com/adf/config">
<adfc-controller-config xmlns="http://xmlns.oracle.com/adf/controller/config">
<lifecycle>
<phase-listener>
<listener-id>myListener</listener-id>
<class>com.xxxx.labs.madison.ptnr.phase.listener.MyPagePhaseListener</class>
</phase-listener>
</lifecycle>
</adfc-controller-config>
</adf-config>
package com.xxxx.labs.madison.ptnr.phase.listener;
import javax.faces.application.FacesMessage;
import javax.faces.context.FacesContext;
import oracle.adf.controller.v2.lifecycle.Lifecycle;
import oracle.adf.controller.v2.lifecycle.PagePhaseEvent;
import oracle.adf.controller.v2.lifecycle.PagePhaseListener;
public class MyPagePhaseListener implements PagePhaseListener {
public MyPagePhaseListener() {
super();
public void afterPhase(PagePhaseEvent pagePhaseEvent) {
System.out.println("inside afterPhase="+pagePhaseEvent.getPhaseId());
System.out.println("getDebugValue="+pagePhaseEvent.getDebugValue());
if (pagePhaseEvent.getPhaseId() == Lifecycle.PREPARE_RENDER_ID) {
System.out.println("Lifecycle.PREPARE_RENDER_ID="+pagePhaseEvent.getDebugValue());
FacesContext fctx = FacesContext.getCurrentInstance();
String viewId = fctx.getViewRoot().getViewId();
FacesMessage message = new FacesMessage("Hello Page no " + viewId);
fctx.addMessage(null, message);
public void beforePhase(PagePhaseEvent pagePhaseEvent) {
System.out.println("inside beforePhase="+pagePhaseEvent.getPhaseId());
System.out.println("getDebugValue="+pagePhaseEvent.getDebugValue());
}

First, ensure the phase listener is working in the subsystem app.
Second, after the master app consumes the child app (as adflib), define the phase listener in the web.xml (within the masterapp).
face-config and taskflow config files are combined but i dont think its the same case for web.xml.

Phase Listener buries exceptions

This is a JSF question sort of...
Can anybody hazard a guess why my JSF Phase Listener does not show exceptions when one gets thrown in a method within this PhaseListener?
I am using ADF/BC and JSF/ADF Faces within JDeveloper 10.1.3.4 and deploying to iAS 10.1.3.4.
I have not tried the same thing in an ADFPhaseListener...chiefly because I wanted a beforePhase() and an afterPhase() method to override, and Source-->Override Methods did not show these methods as being overrideable...so I just used the normal JSF Phase Listener.
My theory is that PhaseListener is perhaps accessed by many sessions?? So it has no way to know to where its stack traces should be directed. So I guess I should use logging with some sort of general catch clause for each method...any ideas will be entertained.
Thanks in advance.

Here's exactly what it says:
The beforePhase() method is called before the standard processing for a particular phase is
performed, while the afterPhase() method is called after the standard processing has been
completed. The JSF implementation must guarantee that, if beforePhase() has been
called on a particular instance, then afterPhase() will also be called, regardless of any
Exceptions that may have been thrown during the actual execution of the lifecycle phase. For
example, let’s say there are three PhaseListeners attached to the lifecycle: A, B, and C, in
that order. A.beforePhase() is called, and executes successfully. B.beforePhase()
is called and throws an exception. Any exceptions thrown during the beforePhase()
listeners must be caught, logged, and swallowed. In this example, C.beforePhase()
must not be called. Then the actual lifecycle phase executes. Any exceptions thrown during
the execution of the actual phase must not be swallowed. When the lifecycle phase exits, due
to an exeception or normal termination, the afterPhase() listeners must be called in
reverse order from the beforePhase() listeners in the following manner.
C.afterPhase() must not be called, since C.beforePhase() was not called.
B.afterPhase() must not be called, since B.beforePhase() did not execute
successfully. A.afterPhase() must be called. Any exceptions thrown during the afterPhase()
listeners must be caught, logged, and swallowedJohn

ADF:How to use NavigationHandler in Phase-Listener with adfc-config.xml

Hi,
in our application a user should be navigated to the login-page, when he tries to navigate directly to a page where he has no right for or if the session is expired.
Our navigation is complete in the adfc-config.xml. So I created a phase-listener, which is called by the adf-settings.xml.
Inside the phase-listener I'm checking the rights. If the user doesn't have the needed rights, he should be linked to the login page. But how can I do that?
Some days ago our navigation has been complete in the faces-config.xml. But now we moved the navigation to the adfc-config.xml, because we are sure that it's better. E.g. for using the dialog framework.
In the face-config.xml we had also the call of the phase-listener. There we did the forwarding like this and it worked:
FacesContext facesContext = FacesContext.getCurrentInstance();
facesContext.getApplication().getNavigationHandler().handleNavigation(facesContext, null, "login_page");But now I think I have to use the ADFContext somehow, or?
So how can I do that with the adfc-config.xml?
Thanks a lot for your help,
Bastian
I'm using JDeveloper 11g Release 1 (11.1.1.3.0)

Hello Frank,
thanks for your answer, but it doesn't really help me, because I'm a newbie, sorry.
Does your answer mean, that I should leave the call of the phase-listener in the faces-config and then I would also have access to the login-page, which is in the adfc-config?
Or does it mean, that I call now my phase-listener by adf-settings but don't have to change the phase-listener itself and can still use my code (FacesContext...)? But that's not working. I get no error but he is also not redirecting.
Maybe my problem starts on an earlier point.
Is it better to create all pages in the adfc-config or faces-config? (Maybe you have a good reference for reading about such a basic discussion)
I thought adfc-config would be the better one. But there I'm not able to redirect to another page (login) if somebody calls a special page without rights for example.
So my second basic question would be about the relation of adfc-config, faces-config and ADFContext and FacesContext.
Because I think it's not a short answer I hope you could give me also for this a reference so that I can read these basics myself.
Thanks a lot for helping a newbie becoming better :-)

How do I set a Phase Listener to only run for a specific page?

How do I set a Phase Listener to only run for a specific page?
I understand that a Phase Listener runs for ever page in the application, however I want a phase listener to only run for one page at the beginning of the application.
I discovered I can't use a Filter, because the JSF Application instance always returns null.
Thus, I thought a Phase Listener would be a good approach.
Thoughts?
Thanks,
--Todd

I have moved forward with checking the requested URI...

Hi how to use phase listener in jsf

hi
i have a scenariao were the data have to fetched form database before the page gets loaded . so i came abt phase listeners . so can anybody give some example for phase listener.....
thanks

This is just basic Java knowledge, but anyway ..public class SomeClass {
    static {
        // static initialization block, this is executed only once per runtime, before the first instantiation.
        // Initialization block, this is executed before the constructor on every instantiation.
    public SomeClass() {
        // the constructor, this is executed on every instantiation.
}

Popup + before phase listener + commandlink issue

All,
I have a before phase listener configured on a page to open a popup and it works pretty well i.e. the popup gets opened when the page is loaded. Now i want to show the same popup when the user clicks on the commandLink. So i configured the commandLink to have a showPopupbehaviour as its child. The issue is when i click on the command link the popup is not getting opened. However if i remove the call to the before phase listener (), the popup is getting invoked from the command link.
Please advice whats wrong in this case ? Ideally both should be working independently.
I tried setting the immediate and auto submit also but no effect.
thnks
Jdev 11.1.1.5

Hi,
using af:showPopupBehavior issues a request to the server, which then also is handled by your phase listener. So you need to add some logic to your phase listener to not process its action when the command button is pressed. You can e.g. set the command button to partialSubmit = true and then check if the request is a partial request AdfContext.getCurrentInstance().isPartialRequest(facesContext) This way the phase listener opens the popup when a page loades but no longer after.

Trouble with Phase Listener?

I am having a problem getting my page beans' "init", "preprocess" and "prerender" methods to fire. My page beans are inherited from "com.sun.jsfcl.app.AbstractPageBean" which do have these methods defined. From what I've found, it appears that my problem is a lack of a "phase-listener" in my faces-config.xml file. How should this be configured? If I put in:
<lifecycle>
<phase-listener>com.sun.jsfcl.app.AbstractPageBean</phase-listener>
</lifecycle>
I get an error that the phase listener can't be instantiated (which makes sense, it is abstract). How do I configure my application so that the "init", "preprocess" and "prerender" methods fire?
Thanks,
Lonnie

I have absolutely no idea what you're talking about. This is not JSF specific.
Maybe you're using some additional JSF component library which offers this stuff. I guess that it is Woodstock again. In any way, you should consult the documentation which come along with the component library for answers on this kind of questions.

What are the steps to define a phase listener in JSF 1.1?

Hello everyone...
Implementing a page listener in JSF 1.2 (the one that comes with JDeveloper 11g) is very straight forward, you implement the methods getPhaseID, beforePhase,afterPhase, and then add the class into the JSF configuration file. It works like charm.
However, doing the same thing with JDeveloper 10.1.3.4 (it comes with JSF 1.1) never works... so I was wondering... Am I missing something? What are the correct steps to do it?
thanks in advance.

Dear Mr. John...
thanks for your kind reply... however, I already was able to implement the Phase Listener successfully in JDeveloper 11g with JSF 1.2 specs. And it works just fine...
what am I asking is that I am doing exactly the same steps under JDeveloper 10.1.3.4 under JSF 1.1 specs, but it does not work at all... so what is the problem? any idea?
best regards

How to get an event programmatically from a phase listener

Hi all,
does anyone know how I can get the component which generated the postback from a phase listener? I need this information because, in my application, I need to log into the database all the buttons and/or options the user clicked.
Thanks in advance,
Monique

Best what you can do is to get all map keys of the ExternalContext#getRequestParameterMap(), those are client ID's of the input elements involved in the form submit, then use UIViewRoot#findComponent() to get the component by client ID and finally determine if it is an instance of UICommand.

ADF Faces: Phase listener

hi folks,
In phase listener can we get which is a last action fired .I
have command links in page with action associated with it ,in phase listener i want to know which action is fired that is which commandlink is clicked
Thanks
Pravin

ok! i know for initial requests (when a user requesting the page for the first time ) the "JavaServer Faces implementation creates an empty view during restore View phase and the life cycle advances to the render response phase".
so i think it is impossible to change Uicomponent state in phase listener !!!! but how can i change Uicomponent attribute before page send to user's browser ?!!

Invoking an ADF Phase Listener

Hi,
I've created and configured an ADF Phase Listener, following Frank Nimphius's instructions from https://blogs.oracle.com/jdevotnharvest/entry/how_to_configure_an_adf_phase_listener_and_where_to_put_the_file
But the listener code apparently never gets accessed when I'm running my application. Is there something else I need to do (other than what is mentioned in the above link) ?
Regards,
Andreas

Hi Vinod,
Thanks for your reply. It turns out that the problem was that I had managed to get adf-settings.xml and adf-config.xml mixed up because I was too tired when I wrote the code. With a proper adf-settings.xml file I can now see my listener code being accessed.
Regards,
Andreas

Ajax component, phase listener and findComponent help

Hello,
I have a component that issues an Ajax Request. This request is collected by a phase-listener and then processed, however I am having difficulties finding the component that I want to re-render.
Is there a common approach for getting hold of components from a PhaseListener ? My scenario is:
When the user clicks and drags inside my component, I want to register the X-axis drag with a ValueChangeListener. (The component has a valueChangeListener="" attribute).
I am able to get the X-axis drag amount sent via Axis and into the PhaseListener, but at this point I am stuck. I now need to get hold of my component, and tell it how much to move the X-axis.
Any help is very much appreciated!

Use of JSF Phase Listener?

There are many many examples of how to 'access' the six phases of the JSF Life Cycle.
I have a simple page that has two input text fields and one command button.
I would like to be able to access the contents of the text fields on the page in Phase 2 (APPLY REQUEST VALUES), or other phases. After quite a bit of time I am posting this in the hopes that someone could point me in the correct direction to do this or perhaps someone has a simple example.
Thanks - Casey

Code for phase listener, backing bean and output are at the bottom of this note.
The text field has a Id property of lname. I assume you are referring about using findComponent() against the backing bean that has a corresponding property (RichInputText) for the text field?
When I run the app I am getting a null for the objReference for the backing bean (line 16 in the output) - see output which then causes a NullPointerException.
Suggestions on how to get the reference to the backing bean, or the component that will contain the data for the input text field?
Thanks again - Casey

Which component fired phase listener ?

Hi,
- I have a custome PagePhaseListener and I would like to know which component of a page fired the listener. Something like:
public void beforePhase(PagePhaseEvent event) {
// log the event.getSource().toString()
- However the code event.getSource().toString() returns the controller object itself and not the object which fired the lifecycle.
Thank you in advance.

I could get which component fired an adf page lifecycle inspection the resquest. Here is the code:
ExternalContext externalContext = FacesContext.getCurrentInstance().getExternalContext();
Map requestMap = externalContext.getRequestMap();
Set set = requestMap.entrySet();
Iterator i = set.iterator();
while(i.hasNext()) {
Map.Entry me = (Map.Entry)i.next();
ILogger.log(this.getClass(), ILogger.TRACE, "request map entry: " + "key: " + me.getKey() + " value: " + me.getValue());
Inserting this code on my custom phase listener I could verify that my master detail implementation was fireing two many requests and what component was responsible of that. Look for keys oracle.adfinternal.view.faces.event.rich.ClientEvents key and oracle.adfinternal.view.faces.renderkit.newStreamingRecords

Phase Listener

Hi everyone,
I need to set up some value bindings and actions listener by code, but i cant find the right phase to do it. I need to setup this bindings before the page is actually in use since the first request. the thing is that putting them after the 1st phase when looking the object by its id, is not found; it is found at the end of the render response, but then is too late.
any ideas?

I have a fragment which contains a subview. this jsp has its own bacinkg bean, but contains two buttons that the action and action listeners should be setted by another backing bean, and the same for an inputText and its value binding.
the main jsp makes an include of the fragment at the end of it, so the main's backing bean constructor is over before the fragment's one has began, so i can`t put there the necesary bindings and behavior i need this 3 elements to have. i can't put this in a method afetr everything has loaded because i need this functionality from the begining since they validation buttons.
