Use of _LINK_TARGET_ in JSF

Hi,
We have a jsf page wherein we have used many textfields, dropdowns..in some scenarios we have to disable certain fields on some special cases and because of this the pagecode methods of some button actions were not getting invoked.
We have resolved this problem by forcefully submitting the page by using __LINK_TARGET__ in the javascript function. Below is the code snippet where "hdSearchbttnAction_" is the name of the button for which we have to call the pagecode method -
document.getElementById("__LINK_TARGET__").value=document.getElementById("hdSearchbttnAction_").title;
var id= document.getElementById("frm_").title;
document.getElementById(id).submit();
This worked but I need to understand why the page dont get submit properly when we disable some components in the jsf page..?? Why we have to forcefully submit the page and what is this LINKTARGET_ and how it works..??
Could anyone please explain this..
Thanks.
Regds,
Lipi

A simple <a> element cannot submit a POST form. That's what the Javascript does which is invoked by the generated <a> element.
Your problem is actually that you didn't knew that HTML input elements which have the 'disabled' attribute set won't send their values to the server side. Rather use the 'readonly' attribute, or use EL to influence the 'disabled' attribute per request, or rethink the approach.
And in the future, please don't be rude on public forums. Kicking a topic up after 2 hours and asking for answer from specifically someone isn't very kind.

Use of filter to JSF faces servlet

Hi
I have a JSF application which is secured by a custom security framework (similar to SITE MINDER). The security framework after authentication passes the authenticated user name within a in-memory session cookie.
The entire user information like his group and access restrictions (field / UI compoonent level) resides in the application database
I have used a filter to JSF Faces servlet to retrieve the user information from the database and storing in session.
Is this use of filter a good approach?

I would fetch such information only once and store it in a simple session scoped bean after a successful login, but I am weird for wanting to do things in a simple way.
A filter can work to validate if the user is still "logged in" (IE. his/her session didn't expire), but since this is JSF you could also use a phase listener for such a purpose.

How to use postback property for JSF to reneder a popup only once

Hi All,
I'm using java script function to show a JSF page as popup. I have called the javascript function on page load of another JSF page.
How do i make sure that the popup is getting rendered only once and not everytime the page is getting refreshed .
Can i use postback property in JSF page for this purpose ?
Thanks in Advance.

try postback..
        Boolean postBackValue = (Boolean)resolveExpression("#{adfFacesContext.postback}");
        Boolean defaultBooleanValue = new Boolean("false");
        if (postBackValue.equals(defaultBooleanValue)) {
public static Object resolveExpression(String expression) {
    FacesContext ctx = FacesContext.getCurrentInstance();
    Application app = ctx.getApplication();
    ExpressionFactory elFactory = app.getExpressionFactory();
    ELContext elContext = ctx.getELContext();
    ValueExpression valueExp = elFactory.createValueExpression(elContext,expression,Object.class);
    return valueExp.getValue(elContext);
}

Problem using javascript to submit jsf form, values not submitted

Greetings!
I have a t:selectOneMenu where I want the page to be submitted when they change the selected value. At this point, I am able to get the form to submit and reload the page, which is all fine. The problem is that none of the values from the page are not set in the backing bean. I have break points on the setter methods that are not being hit.
I have tried a number of things from searching multiple forums, but here are snippets from my latest version...
<h:form>
<t:commandLink id="hiddenLink" forceId="true" value="test link"
action="#{pc_PageX.doBtnHiddenLinkAction}"></t:commandLink>
<t:selectOneMenu id="pageList_top" forceId="true" value="#{pc_PageX.ValueX}"
     onchange="jspellSync(); submitPageX();">
     <f:selectItems value="#{pc_PageX.ListX}" />
</t:selectOneMenu>
</h:form>
function submitPageX(){
     var hiddenLink = document.getElementById("hiddenLink");
     hiddenLink.click();
}Note that the <t:commandLink> is not hidden, though it will be in the final version if I can get this to work.
If I click the commandLink myself, the page is submitted with all the page values as expected. If I change the list value, thus using javascript to fire the commandLink's click event, the page is submitted with NO values.
Can anyone come up with an explanation for this behavior? Or better yet, a solution?
A couple other things I've tried...
- Not using a commandLink and using jsf's submit function -> onchange="jspellSync(); submit();"
- Clicking the link using other ways -> hiddenLink.fireEvent('onclick');
If all else fails, I'll just add a button that they have to click to submit the form.

I recall this problem in one of the ancient JSF versions. Which JSF version do you use? Do you have any room to upgrade to latest? We're using an IBM implementation of JSF, which is at version 7.0. The IBM implementation appears to be built on the JSF base 1.1.That's not an IBM JSF implementation, they do not have any one, they just have some component libraries which runs on top of some JSF implementation. RAD/WSAD ships by default with Sun JSF RI. Try upgrading to at least 1.1_02 which you can download from the aforementioned link. There's a gap of 2 years (and inherently a lot of bugfixes) compared to 1.1. If the application server used supports Servlet 2.5, you could even upgrade to the latest 1.2.
We've had other issues with the IBM implementation, which could be the cause in this case too. We've been talking about switching to MyFaces, but there is one feature of the IBM version that we like. It's basically a script collector (hx:scriptCollector) that allows us to do pre-processing on the page.As said before, IBM does not have a JSF implementation. So replacing RI by MyFaces wouldn't make any difference.

2) demo.jsp is given below

<h:outputText value="Hello"/>
</body>
</html>
</ui:composition>
</jsp:root>
but when i run this application i get error as follows:
javax.servlet.ServletException: @15,48 <jsp:include> Tag Library supports namespace: http://java.sun.com/JSP/Page, but no tag was defined for name: include

You're mixing two view technologies with each other: JSP and Facelets. You cannot do that. Use the one or the other. In Facelets you can just use <ui:include>. Leave all of those legacy <jsp> tags out when using Facelets.
By the way, although the <f:subview> is superfluous in Facelets and only used in JSP, I wanted to tell you, this tag is better to be placed in the include file, not in the parent file. Otherwise you may risk "duplicate component ID" problems.

Using Business Components in JSF pages

I have several questions about using BCs in JavaServer Faces pages. I'm new to the JSF-BC development world.
Here's what I'm trying to accomplish: a salesperson gets a call from a customer requesting a quote. The salesperson selects the URL for my RFQ form and begins filling it out. If there is an existing customer record in the company's database, the salesperson wants to be able to load customer info into the form from the database, rather than typing it all in. Reasonable enough, and probably simply enough.
But it's kickin' my butt. I've created the domain objects (including one for the customer database, call it "CU") and the model objects (a View Object that filters out all fields but those needed on the form, an Application Module with a View Object Instance). Initially I am routing from the main form window to a dialog window where I am hosting the customer selection components, intending to return to the main window with the selection. On the dialog window I've dropped the VO and configured it to be an ADF Navigation List (which gets implemented as an af:selectOneChoice component). So far so good. The navigation to and from is working fine. The selectOneChoice list is being populated with the first range of returned records. Here's where I'm stuck.
First of all I can't figure out how to kick the iterator into sending additional records after it's first range. You can scroll down to the end of the list in the selectOneChoice component but nothing happens after that. I know I can set the iterator's range to 0 to get all of the records dumped in at once, but that takes way too long. Any ideas?
Secondly, when a selection is made, how do I access the selected data? I have set up a ValueChangeListener method in my dialog's backing bean that gets the NewValue() from the event object, but that value turns out to be the index into the collection of selectItems. How do I get the value of the data that shows in the list? Is that the label of the selectItem? If so, how do I access it? What I really want is to get the entire row of data represented by the returned index, but I'm lost as to how to do that. Any help would be much appreciated.
At some point I want to let the salesperson type in a partial customer name and then retrieve only records matching the query's where clause. I see where I can create a bind variable on the view object, but am not sure how to pass the partial name value from the main form to the dialog. Currently I use an EL expression in the Action attribute of an af:selectInputText component to navigate to the dialog and I don't think I can pass parameters with that. I guess I would have to switch to using a method binding to a backing bean, eh? But even if I can get the partial name value to the dialog, how do I bind that value to the bind variable of the VO? (the VO that is already bound to the af:selectOneChoice component in the dialog.)
And I am totally open to alternative suggestions for how to accomplish the original intention of all of this. Thanks for any guidance.
Johnny Lee

Thanks, Shay. That has gotten me a few steps further along. I modified my VO by creating a bind variable and modified the SQL to use this variable in it's where clause. I generated Java for my AppMod (which I hadn't done before, preferring to keep things simple) and created a method to supply a value to my VO's new bind variable. I need a little more hand-holding, though, to wire an input text field & button (or af:selectInputText?) to both the AppMod's new method AND the data component that will display the query results.
"...drag the exposed method as a button onto a JSF page." That's easy enough, but I haven't yet figured out from the examples how to associate the value of an input component with the parameter of the AppMod's new method. It's getting late, I'm starting to see cross-eyed so I will sleep on this and take another look in the morning. Thanks for your help.

If you are trying to display total number of pages in a report, Add the below formula in the column of the report and hide that column in the report.
FX = sum(count(1))/25
You can then reference the column in the narrative view like this: "Total pages in the report are @5" and out put may be "Total Pages in the report are 30".
Or
You can also use something like the below:
To calculate them use fi:
CEILING(CAST(RCOUNT("FactColumn In the Report (Sum All)") as DOUBLE)/ 25) for the page number
CEILING(CAST(COUNT("FactColumn In the Report (Sum All)") as DOUBLE)/ 25) for the total pages
Put the above formula in the column and reference it in the narrative view like I mentioned in the previous example.
If you are report view is pivot, then please refer to this link: http://oraclebizint.wordpress.com/2008/01/17/oracle-bi-101332-pagination-in-pivot-tables/
Hope this helps.

How to use HTML tags inside JSF pages

Can some one help me, how do i use HTML tags inside <h:dataTable>.
Or is their any other way i should form my Menus, to fully utilize to HTML tags.
Thanks
Ravi

Hello,
You can embed the verbatim elements in your datatable, ie,
<h:dataTable value="#{menuItem.breadCrumb}" var="bread" >
<h:column>
    <f:verbatim><li></f:verbatim>
    <h:outputLink id="crumbID" value="#{bread.menuLink}">
      <h:outputText id="crumpName" value="#{bread.menuLabel}" style="width: 165px;"/>
    </h:outputLink>
    <f:verbatim></li></f:verbatim>
</h:column>
</h:dataTable>

How to use web services in JSF app

I am unsure if this is the right forum for this question. Let me know if it is not - and where I should go.
Anyways, I'm building a JSF web app, in which there is a datatable page displaying some business data. The app is going to be deployed and run in the customer's web server, but the data to be displayed is from the business solution provider's database. Currently the provider supplies web services to retrieve the data. So, my task is to call these web services from my JSF page, get and display the data.
I've never used web services before. Can someone give me a quick start, as what I need to know to use these web services, and how to use them in coding terms. I googled the web quite a bit and finally decided to turn to SDN forum.
Thanks!

Using Java constant in JSF

Hello!
I�m new in JSF and I want to use a constant into a jsf tag but I don�t know how to do it. I know in JSTL but not in FSF.
This is what I want:
     <h:outputText id="test"     value="<%Constantes.DOCUMENT%>"/>     I have tried so many things to use my constant in the value element but I don�t know the way
Thanks.

first off Scriplets are bad practice in JSF and should be avoided.
I use this workaround for constants in jsf. Create a my constant as properties on a FacesConstants class, which is defined as a Managed Bean with scope of none and having getters for each property.
public class FacesConstants implements MyConstants{
public String document = DOCUMENT;
public String getDocument(){
return document;
<managed-bean>
     <description>used to get faces constants for refereing in EL Expresssions</description>
          <managed-bean-name>constants</managed-bean-name>
          <managed-bean-class>com.myproj.faces.util.FacesConstants</managed-bean-class>
          <managed-bean-scope>none</managed-bean-scope>
</managed-bean>
so in the jsf code just say #{constants.document}
Not sure if this is best practice? in fact I'd prefer a more elegant solution

Can I use grid layout in JSF visual page designer ?

Hello dears...
I am using Jdeveloper 11 g and 10 g .
When I tried to use JSF visual editor (from the component palette), and when I drag any control to the page I found that the control go to the top left of the page
and I even can not move the control to another place in the page by the mouse.
the JSF visual designer seems to use flow layout for the page . (the same as using flow layout in the swing applications).
The question is Can I change the page layout to be grid layout instead of flow layout ?????? (to be able to move any control to anywhere in the page.)
Note that in netbeans 6.1 , when u design JSF page , you have 2 options for the page layout, grid layout and flow layout and u can choose as u like.
Is this feature found in jdeveloper 11 ?????
if not , Can anybody tell me any workaround to design JSF pages without using flow layout ????
Thanks in advance
Samy
Edited by: user10653280 on Nov 29, 2008 1:30 PM

We don't provide absolute positioning for JSF application - this is a bad practice since it fills your JSF page with CSS code and create applications that are not portable between different screen/monitor resolutions - so we use flow layout instead and provide a much richer set of layout components.
