Calling managed bean method using ajax on jsp page loading

Hello,
I am using jsf1.1 i want to call managed bean method when page gets loaded using ajax.
Thanks
K.Ramu

Use an ajaxical JSF framework, for example Ajax4jsf (part of RichFaces).
But why don´t you just use the constructor of the bean class to do some stuff prior to page loading?

Call managed bean function using javascript

Any one help me how to call managed bean function through Javascript onload() event.

Manage bean methods not able to call application module methods

Hi,
I have an ADF application where in my managed bean method needs to call AppModuleImpl methods. I use the code as below:
public void getSummary() {
DCBindingContainer binding = (DCBindingContainer)BindingContext.getCurrent().getCurrentBindingsEntry();
OperationBinding op = binding.getOperationBinding("getVOData");
op.execute();
The code works fine when I run the application in my IntegratedWeblogicServer and I am able to get the data on my .jsp pages.
I have installed weblogic server on another machine and I need to deploy and run my application on that server. But when I try doing that, the above code is not able to call the AppModule method and I see no data on my page (Also there is no error or exceptin thrown). Seems that the ViewController project is not able to interact with the Model project.
Is there any extra configuration to be done on the newly installed weblogic server to get this work? Or will some change in the application code help?
Please suggest.
Thanks and regards,
Ansh

Hi,
While creating the weblogic domain, we had the following checkboxes checked:
1. Basic weblogic server domain [wlserver_10.3]
2. Oracle JRF [oracle_common]
I hope this is what we need.
Yes, I also have the adf runtime installed.

Is it possible to call any Managed Bean method from af:goLink

Hi,
I am using RichGoLink component.
Is it possible to call a managed bean method on click of the af:goLink? I want to provide some validations when user clicks on the goLink.
There is no any actionListener provided.
Thanks in advance.

Hi,
I am able to resolve my second problem also.
i wanted to set the "destination" of the goLink on the fly. To do this I created a custom componnt by extending the RichGoLink and I override the encodeBegin method in that class. In this method i check my condition and then set the "destination" property.
I am still using the clientListener and the serverListerner to do some further testing that i wanted to. Here one thing you have to keep in mind that. In the javascript function that we are calling in the clientListener should not do the "cancel" on the event object, if you do so it will not navigate to the required position.
Thanks for the way you showed to resolve my problem. Hope you understand the way i worked for this solution.

How to call different managed bean methods on a page template button

Dear All,
Use Case:
I have a Page Template and inside this page template is a popup screen which is common to all my
pages. My popup has OK and Cancel button only.
My question is this, there are lots of pages that uses this template.
How is it possible to invoke a managed bean methods dialoglistener when say for example the user clicks the OK button?
One thing common among the pages is that they are included in some kind of a taskflow and I have configured
a managedbean in a pageflowscope variable in each taskflow and I just wanted to pass the
My Template
     - TaskFlow 1 (ManagedBean1.dialogListener)
     - TaskFlow 2 (ManagedBean2.dialogListener)
     - TaskFlow 3 (ManagedBean3.dialogListener)
Each dialog listener does different things.

How to call a bean method in the faces-config file?

Hi,
I would like in my menu to call the method of a bean (it initialize some properties before opening the page) instead of opening directly the page, by I can't find how to do that.
I tried :
<managed-property>
<property-name>viewId</property-name>
<value>#{listInformationsController.listInformations}</value>
</managed-property>
And :
<managed-property>
<property-name>outcome</property-name>
<value>#{listInformationsController.listInformations}</value>
</managed-property>
With no success...
Can someone help me?
Thank you and merry christmas !

Hi,
a managed property only gives you a anlde to a bean or property, it doesn't execute it. To execute a bean, you can use a custom JSF PhaseListener that calls a bean method. The reference to the bean is achieve through value binding
ValueBinding vb = FacesContect.getCurrentInstance().getApplication().createValueBinding("Name of Managed Bean);
TypeOfBean theBean =(TypeOfBean) vb.getValue(FacesContext.getCurrentInstance());
.... theBean.theMethod() ...

Rendered Property calling managed bean Multiple Times

Hi
We have a problem within a command button in a jspx, which includes a rendered tag which references a managed bean method via EL.
e.g.
rendered="#{PERUserInfo.trainee}"
When I debug the jspx, the PERUserInfo.trainee method is called 4 times instead of once.
We have noticed similar findings when using managed bean methods via the rendered property. i.e. calls getters multiple times.
Any idea why this is happening?
We are using JDeveloper v10.1.3, JHS v10.1.3 SU1.
All comments appreciated.
Cheers
Denis

Denis,
There can be many reasons why your bean method is called multiple times; but I would consider this perfectly normal in any JSF application considering all the lifecycles and (possible) Partial Page Rendering that happens.
The question is, by the way, more appropriate on the JDeveloper forum since it is not directly related to JHeadstart itself.
Hope this helps,

af:fileDownloadActionListener not calling the bean method

Hello,
I am using Jdev 11.1.1.6.
I have a page where user can generate the report and download it. I am using <af:fileDownloadActionListener> for this on my jsff (implemented as region using BTF).
The commandbutton with <af:fileDownloadActionListener> is calling a backing bean method. When user clicks the "Print" button, it is supposed to generate the report and allow user to download it.
The issue here is that the control never goes to bean method after button press. The browser keeps showing busy but no control passed to bean method. Interestingly, after you close the browser, it immediately goes to bean method.
I have tried waiting for long time (some times 15-20 min) but it never goes there during execution.
What could be going wrong here?
Code snippet from my jsff:
<af:commandButton id="cb1"
                  textAndAccessKey="Print"
                  partialSubmit="false"
                  clientComponent="true">
               <af:fileDownloadActionListener method="#{someMethod}"
                                              filename="#{someName}"/>
</af:commandButton>This is really frustrating as I have no clue what is going wrong here. The similar code works in other page but not here.
I would highly appreciate help here.
Thanks,
Jai

Like I said, it is working fine on my other pages and I tried on new page, just like yours, and it worked. It is not working where I need it.
I know the issue is somewhere with my page [child or parent, explained later] and I am looking for help on finding the root cause. Some direction/tip which I can follow and figure out the issue.
Other buttons are working fine on the page but <af:fileDownloadActionListener> does not work. The page seems to go in loop as it keeps printing generic messages that are generally printed when page is submitted.
This will continue until you close the page/browser and then the control goes to bean method.
Let me explain page structure:
My application is based on UIShell and is basically based one page application. Every page (jsff) is implemented as region using BTF. When user clicks on menu, MainPage is opened. This MainPage represents main structure using layout components like panelGroupLayout, panelTabbed, showDetailItem etc. These layout components contains <af:region> implemented using BTF.
The MainPage which has this issue is large page with almost 100+ BTF af:regions implemented under panelTabbed+showDetailItem combination.
<af:fileDownloadActionListener> has been implemented on one of the <af:region>, which is part of this MainPage.
Few Observations:
1. If I move this button [with <af:fileDownloadActionListener>] to any of the af:region under current MainPage then it does not work.
2. If I move this button [with <af:fileDownloadActionListener>] to any independent page or any <af:region> which is part of some other MainPage, then it works.
3. Other MainPage where it is working fine is also a fairly large page with almost 150+ BTF af:regions
4. All our MainPages are based on template, so there is very high level of consistency in behavior and other handlings.
For whatever reason, it is not working on my current page and I would highly appreciate any input based on above info [or otherwise] to find a root cause for this issue.
If I need to debug, where should I start? What could be causing that looping behavior, specially with <af:fileDownloadActionListener>.
Thanks,
Jai

How to call a bean method from javascript event

Hi,
Basically, I would like to call a method that I have written in the page java bean, or in the session bean, or application bean, or an external bean, from the javascript events (mouseover, on click, etc...) of a ui jsf component.

Calling a bean method on select of Combo box item

Hi
On select of Combo box item in a form, text fields in the same form should be populated
dynamically.Is it possible to call a bean method which does this,by calling onSelect() method
of combo box ?
Thanks in advance,
Sridevi

Uff, sorry!
I ment that you write some code for the "onSelect" event which sends a request to the server with the selected value: onSelect="self.location.href='<%= request.getRequestURI()%>?selectedVal= ' + this.selectedIndex;"
