How to call the backing bean method through javascript by closing window?

Hi all,
What I want to do is:
I open a new page by clicking <t:commanLink.../> from the first page. Then I close the new page. By closing the new page I will call a function in the backing bean such as myBean.doSomething() to do something. Such like:
<body onUnload=jsFunction()..../>
...

So far I understand, I should write following code
in my second page:
<html>
<head>
<script type="txet/javascript">
function jsFunction()
{>
ocument.forms[0].action="#{myBean.doSomething}";
document.forms[0].submit();
</scrip>
</head>
<body onunload="jsFunction()">
<ui:composition>
<h:form id="myForm">
<t:commandLink id="myLink" immediate="true"
action="#{myBean.doSomething}"
value=""></t:commandLink>
</h:form>
</ui:composition>
Is that right? I am not sure if I've the javascript
in the right position.I am sorry! That solution will not work. My Bad.
You can try this.
1) Have a invisible command button on your first page with the action attribute set to "#{myBean.doSomething}" as below
<t:commandButton style="width:0px;height:0px" id="myButton" immediate="true"
action="#{myBean.doSomething}"
value=""></t:commandButton>2) Your JS onunload method on the second page should look like
<script type="txet/javascript">
function jsFunction()
var buttonObject= window.parent.document.getElementById("formname:myButton");
buttonObject.click(); // This would help in submitting the first page
// to submit to the needed action method
</script>Karthik

Calling a backing bean method after load of fragment in adf

I needed to call a backing bean method after page load of fragment in adf.
I used the method suggested in:
https://community.oracle.com/message/11044570
only difference is im giving the if clause as:
if (refreshFlag == RegionBinding.RENDER_MODEL ) {
instead of
if (refreshFlag == RegionBinding.PREPARE_MODEL)
It was working fine, but page was not getting refreshed so used the code as mentioned in example:
public void refresh() {
          FacesContext facesContext = FacesContext.getCurrentInstance();
          String refreshpage = facesContext.getViewRoot().getViewId();
          ViewHandler viewHandler =facesContext.getApplication().getViewHandler();
          UIViewRoot viewroot = viewHandler.createView( facesContext, refreshpage);
          viewroot.setViewId(refreshpage);
          facesContext.setViewRoot(viewroot);
Now issue is once page is loaded and backing bean method is called, the refresh code refreshes the page and upon page load, refresh method is called again in recursive fashion.
please advise what to do in such scenario?
I tried to do selective refresh using some variable(also with static) but it does not help as page wont be refresh at all or page will keep refreshing recursively.

Use clientListener on the page load event
<af:document id=”d1″>
    <af:serverListener type=”onloadEvent”
                       method=”#{<managedbean name>.<method name>}”/>
    <af:clientListener method=”onLoadClient” type=”load”/>
    <af:resource type=”javascript”>
    function onLoadClient(event) {
      AdfCustomEvent.queue(event.getSource(),”onloadEvent”,{},false);
      return true;
    </af:resource>

How to call the form bean value on jsp withthe help of jstl tag

hi

i now how to retrive the value through jsp:logic
eg. <logic:empty name="userListForm" property="users">
NO USER FOUND
</logic:empty>
see * userListForm mean formbaen name.
* users means collection object.

You use the jstl core:if or core:choose combined with the EL:

NO USERS FOUND
</c:if>I suggest you lookup the jsp expression language (EL) using google, it's very powerful.

How to call the screen in methods could u please explain

hi,
how to call the screen in methods could u please explain clearly with example

HI ,
CALL SCREEN - Call a screen
Basic form
CALL SCREEN scr.
Addition:
... STARTING AT x1 y1 ... ENDING AT x2 y2
Effect
Calls the screen scr; scr is the number of a screen of the main program. You use SET SCREEN 0. or LEAVE SCREEN. to define the return from the CALL screen.
Note
Please consult Data Area and Modularization Unit Organization documentation as well.
Addition
... STARTING AT x1 y1 ENDING AT x2 y2
Effect
The coordinates x1, y1 (start column and start line in the window) and x2, y2 (end column and end line in the window) define the size and position of the CALL screen ("top left - bottom right"). Besides these coordinates, you can also see the contents of the primary window, but cannot perform any action there.
Note
If "ENDING AT ..." is not specified, suitable values are substituted for x2 and y2, taking into account the size of the called screen.
Exceptions
Non-Catchable Exceptions
Cause: No further screen level (call screen); the maximum number of nested screen levels is restricted to 50 at present.
Runtime Error: DYNP_TOO_MANY_CALL_SCREENS

Calling a backing bean method by clicking on an image.

I have several HtmlGraphicImage (h:graphicImage) objects on a page. I would like to be able to call a method inside the backing bean for the JSP page where the images are located when the user clicks on one of the images, and have a parameter sent to that method in the backing bean that will tell it which image was clicked on.
How can this be done? Unlike buttons that have an action that gets listend to in the backing bean, HtmlGraphicImage objects do not have actions. I know that you can intercept clicks by an onClick Javascript method, but how can you call a mehtod in the backing bean using the Javascript onClick?
For example, part of my JSP looks like this:
           <body style="background-color: rgb(255, 255, 255); -rave-layout: grid">
                <h:form binding="#{InitialReport.form1}" id="form1">
                    <h:graphicImage binding="#{InitialReport.frontalImage}" height="204" id="frontalImage" style="left: 144px; top: 240px; position: absolute" width="242"/>
                    <h:graphicImage binding="#{InitialReport.profileImage}" height="198" id="profileImage" style="left: 432px; top: 240px; position: absolute" width="244"/>
                    <h:graphicImage binding="#{InitialReport.smileImage}" height="198" id="smileImage" style="left: 720px; top: 240px; position: absolute" width="244"/>If my backing bean (InitialReport.java) had a method that looked like this:
public void setCurrentImage(String imageName)what would the javascript look like in order to send a name to setCurrentImage?
Thanks!

you can use the <h:button> with type='image'Thanks for the reply, but I cannot use that. The thing is, the images are read at run time from a database and are not present in the resources. The button's image only takes String file names, not URLs.
There should be a way to do this using onClick.

Urgent: calling my backing bean method.

I have a menu option implemented as a <h:commandLink> component and I want to call a MailBoxBean's method call checkMailBox(). This method checks some information on a database and returns a "success" String if everything is ok. The Bean is "configured" so that redirects to a mailbox.jsp if the "success" String is thje outcome. The information is shown on mailbox.jsp.
The problem is that I can't get to the checkMailBox() method through the <h:commandLink> component although I have written the action attribute like this: <h:commanLink action="#{mailbox.checkMailBox}">.
What's wrong with this?

Thanks for answering so quickly. The fact is that I have my Bean declared and the navigation rule setted both in my faces-config.xml file.
The firts problem I am having is that the menu option implemented with that <h:commandLink> component is not correctly rendered as I get some kind of javascript error, but I can see much more cause I'm using MS's Explorer.
<h:commanLink action="#{mailbox.checkMailBox}" immediate="true">
<h:outputText value="Check mailbox"/>
</h:commandLink>
Is these correct??

How to execute a backing-bean method before loading JSP Page?

Hi everybody.
Scene:
An AdfForm, with
-SelectChoice, referenced to a <list> of pageDef, which is referenced to an ADF BC.
Goal:
-Executing the query of the ADF BC before load the SelectChoice, to load the correct values.
A good question to know:
Exists any way to execute a method of backing before loading a JSP Page?
Any similar to onload method of javascript. It could be fantastic.
Thanks in advance,
Jaime

hi Jaime
If I understand correctly, you are using the ADF Model for data binding.
Because your goal is "Executing the query of the ADF BC ...", maybe you can also consider to refresh an executable in your Page Definition.
See also "10.5.5 How to Use Refresh Correctly for InvokeAction and Iterator Bindings"
at http://download.oracle.com/docs/html/B25947_01/bcdcpal005.htm#BJECHBHF
It says "... You can use the Refresh property on iterator bindings and invokeAction executables in your page definition to control when each are evaluated during the ADF page lifecycle, either during the prepareModel phase, the prepareRender phase, or both. ...".
Although you have posted your question in a structured way, which is a good thing, I think it would help to understand your question if you can explain how you determine "the correct values" for your list, what is varying?

Somehow ejbCreate method of an Entity EJB is not inserting a record into the database. I'm using BMP and calling the Entity bean method from a servlet. I'm using NAS 4.0 sp5 on Win 2k.

Also if I call the insert query from within the servlet it works fine. I have disabled global transactions. Am I missing something out ? Please
any help would be greatly appreciated.

May be your servlet is not able to lookup the EJB. You can use some print statements and see whether lookup ok or not.
Just a guess.
Plese get back, if any queries.
Thanks,
Rakesh.

Can I pass a param to the backing bean method?

For example:
<h:dataTable id="recentUpdateTable" var="video" value="#{VideoListBean.recentUpdated}">
I want to pass a param to VideoListBean.getRecentUpdated(). The param can not be a request param
How to do it?
Thanks in advance.

Maybe I should describe my question more clearly.
For example:
<h:dataTable id="foo1" var="list" value="#{test.list">
<h:dataTable id="foo2" var="video" value="#{test.subList}">
</h:dataTable>
</h:dataTable>
The subList is determined by a property of list but how can I pass the property to test.getSubList() ?
Thank you!
