Jsf page components

Hi,
Iam a newbie to JSF. I want a know whether we can design a JSF page which contains Swing components? that means the look and feel must be like swing. It should not change from Os to Os or browser to browser.
Thanks..

You cannot use Swing components to draw a JSF page. JFC and JSF are different technologies aimed at different markets. JFC is useful for stand-alone application programming, where JSF is a web framework for web applications.
Therefore, JSF is dependent on how the browser decides to render the HTML JSF generates. You will get close to the same page across all OSes and all browsers, but there will always be some differences in the way each page outputs.

How to use Apache MyFaces components in JSF pages + Eclipse?

I've managed to write my JSF web app. in Eclipse jee, and test it on JBoss 4.2 GA, within Eclipse, but how to import Apache MyFaces components into Eclipse JSF plug-in?
If I can't import it nicely, how to use those components directly in JSF pages?

The Tomahawk component library provides MyFaces components. Install it as you would any other component library.

How to align the components in a jsf page?

Hi all,
In my use case I need to use three UI components like push down menu
a textbox and a button. when I dragged all the things on to my jsf page
I am getting one by one.( I mean to say that I am getting button beneath pushdown
and pushdown beneath the text box)
I want all these components adjacent to each other.Kindly come up with the suggestions.
Thanks,
Phani.

These three components surround with af:panelGroupLayout and set af:panelGroupLayout layout property to horizontal (you can find layout property in common section of Property Inspector).

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.

On JSF Page load UI components loading sequence

Hi All,
I have some questions about the UI components loading sequence on the JSF page load.
When a JSF page loads it loads its UI components which have a sequence of getters and setters declared in the backing bean of that jspx page.
Qustion 1: How these getters and setters in backing bean work in loading the jspx page?
Question 2: How this backing bean is related to the Page Definition file for the page loading?
Question 3 (main query): What is the sequence of the getters and setters. Means, if i drop 3 UI components, 1 input text, then a command button and then an output text, then they are accordingly declared in backing bean. On page load first i/p texts getter gets called, then setter, then command button's and theno/p texts, in these sequence.
But can i manipulate their sequence of loading. If yes then how it can be possible?

Answer 1: Getters and Setters in bean normally will be bounded to ui component's properties in jspx page, when jspx page loads these getters get called through introspection and setters gets called when a request is submitted.
Answer 2: Backing bean and page definition are two different entities and they are no way related unless you have a data control for the backing bean and have bindings for those methods in page definition file
Answer 3: The sequence of getters and setters depends on the order of the components they bounded to in jspx page. components in jsf page gets loaded from top to bottom so the getter bound to the top component gets called first and the getter bound to bottom component gets called last.
The only way to change the sequence of getter methods getting called is to just change the order of the components they bound to in jspx page.
Usually, it is not suggested to put business logic inside getters and setters, where you have action and actionlisteners for the same. If you follow that, you don't need to worry of the sequence of getters and setters execution

How to Use another JSF page that I load by XMLHttpRequest?

Hi everyone, I'm a newbie of JSF and curisous about how to load page content seperately by AJAX.
I saw example of Java Blue Print. It's load some data to use in page. What I want is to load another JSF page when click a link or button, (Like include another page). And work with functions privoided by loaded JSF Page.
My example is, In a main page. I request a JSF page and set it into a div layer.
var requestURL = "/admin/customer/customer-list-body.faces";
var content = postDataWithoutContent(requestURL); divContent.innerHTML = content;
All JSF components are required under <f:view>, thus action of form is set as "action='"/admin/customer/customer-list-body.faces'"
But my page is main.jsp. Each time I click command button in customer-list-body.faces, the url will change to customer-list-body.faces, I want to request and hold in main.jsp.
What can I do then? Any advices?

Hi,
the list doesn't seem to be your problem. You need to track down the illegal argument exception. Once you have that sorted out, expose the method on the AM so it gets shown as a method binding. The return values then could be picked up in a managed bean to create the select Item list

Unable to get the output when i run any jsf page in adf

Hi,
I have created one jsf page to access the business components which i had created earlier after that when i drop the another panel splitter into the second facet of the initial panel splitter we created , I was unable to see in the workspace (.jpx) window.can you suggest me on this.
after done all the steps if I tried to run that page it starts the WLS servier and createda URL but the url is taking long time approx more that two hour and still not getting the required output only the loading window I can see.
Please suggest me on this.
Thanks
Chetan

Hi,
the panelSplitter should at least show in the Structure Window. So check if it is there. The runtime issue can be caused by the proxy settings. Go to Tools / Preferences --> Browser and Proxy and add localhost to the list of exclusion
If you are new to ADF I recommend running a tutorial like this: http://www.oracle.com/webfolder/technetwork/tutorials/obe/jdev/obe11jdev/ps1/ria_application/developriaapplication_long.htm

How to populate a html table in a JSF page

Hi, I need help on the following issue:
My code calls an business layer API which returns me a string in html format which produces a html table. I have a JSF page with a bunch of other JSF components and I want to insert this html table at the bottom of this page. Is there a way to do it?

OK
Here is an example
Drag an outputText component on to the Page. Check the properties of outputText and uncheck the escape property. Write this some where in the code when you want to display the HTML table on the page.
String s = "<HTML><BODY><TABLE BORDER=2><TR><TD>No</TD><TD>Name</TD><TD>Age</TD></TR><TR><TD>1</TD><TD>John</TD><TD>30</TD></TR><TR><TD>2</TD><TD>Michael</TD><TD>20</TD></TR></TABLE></BODY></HTML>";
outputText1.setValue(s);
I am using the hardcoded value for String but in your case you get the string from some API.
Hope this helps
Thanks

Calling a method in the Custom ADF component from JSF page

HI.
I have created some custom compoents by extending the core ADF Components. Like i have a ComboBoxDefault component with it's ComboBoxDefaultTag.java and Controls.tld file.
Now my requirement is i want to bind my label to this component from the JSF page. like
<fwcontrols:label binding="#{listComponents.comboBoxDefaultLabel}" id="label1"/>
<fwcontrols:comboBoxDefault binding="#{listComponents.cmbLocales}"
value="en_GB" id="comboBoxDefault" autoSubmit="true" label="label1">
<f:selectItems value="#{listComponents.locales}"/>
</fwcontrols:comboBoxDefault>
In my JSF page the label will have an id, and that id will be specified in the label tag of the component.
In Tag.java file i have overrided the setProperty(FacesBean facesBean). In this method i have bind all my properties. In core JSF the setProperty method is provided with the UIComponent parameter, so i can call my method in component also. Which is not in case of ADF Faces.
My main point is how i can call my method setLabel() which is in ComboBoxDefault.java so that i can set the label.
Thanks in Advance.

Thanks for all your replies. I want this kind of a functionality because Im trying to invove a DC (Child DC) from a Parent DC such that the Child DC's view is displayed onto the view container of the Parent DC. I have embedded using 'interface view of a component instance' in the Parent Window and am able to create the component and set usage though the onPlugDefault of the Child View.
But I observe that when i make a call from the parent, the flow is like this:
1. The wdDoInit of the Child Component Controller gets triggered first.
2. Then the wdDoInit of the Child's <b>VIEW</b> gets triggered
3. and <b>THEN</b> the onPlugDefault of the Child Component Interface View
What I had actually wanted was to Fire onPlugDefault where Im calling a method LoadData(), after which the Child DC's view must be triggered so it can display the fetched data.
What is actually happening is the view gets displayed, but no data is displayed in the view.
Right now I have just given a work around where Im triggering <b>LoadData()</b> of the <b>COmponent COntroller</b> from the <b>wdDoInit</b> of the <b>VIEW</b>.
Is there a better way to do this? I find it strange that I have to load the Data from the view.
Thanks

Embedding a declarative component written in JSF 1.2 in a jsf page

Hi ,
I have a declarative component written in JSF 1.2 . I want to embed this declarative component in an ADF application which is using JSF 2.0.
On creating a jspx page in JSF 2.0 & embedding decalrative component it just works fine but I have to embed it in a JSF page instead , which is not working.
Any suggestions ?
Thanks
Vinit

Hi,
for JDeveloper 11g R2 you will need to know before whether the application you build uses JSPX page documents or Facelets. The technologies are different (introduced with JSF 2) and declarative components thus need to be build for the document type used by teh application

How to fire an event dynamically in JSF Page

Hi All
How to fire an event dynamically in JSF Page?
Thanks
Sudhakar

Hi,
Thanks for the response. I mean to say, if I create the components dynamically then how can I fire events for those components.
In otherwords,
If I create the Button dynamically with particular ID being set to that component, then how can I call button action event when the button is clicked??
Hope you understand
What is the role of MethodBinding mechanism here??
Thanks

Catching an exception in an JSF page

Hi,
I have made the following example:
In my jsf page I have:
<a4j:commandButton id="save" action="#{settings.save}"
reRender="attributes" />
<h:outputLabel value="Save" for="save" />
<table width="100%" cellpadding="0" cellspacing="0">

<tr>
<td><ui:include src="/attributes.xhtml">
<ui:param name="parent" value="#{settings}" />
</ui:include></td>
</tr>
</table>
In SettingsBean.java
public void save() throws exception
try
doSomething();
catch(Exception e)
// catch the exception here and send it back to the jsf page????
I want to be able to catch the exception when it occurs in my jsf page. If the exception arrises I want to add some extra buttons.
Any ideas how to resolve this?
Thanks in advance

JSF does not work like JSP, even when using JSP with JSF, in that the execution is decoupled from the page being processed. So you cannot catch exceptions in JSF views.
Assuming I have sufficiently confused you now, let me give you some ideas as to how to handle your situation. The usual way this is handled is to register a message when an exception occurs which are then displayed by <h:messages> or <h:message> components.
However, this does not appear to be suitable for your purpose as you require specialized output when the exception occurs. So you could store a flag (or even the exception itself) in a backing bean and use the rendered property of all components to conditionally display your buttons. BUT you will need to take care that the dynamic value of the rendered property will be the same on the subsequent request or the actions for the buttons will not be queued.

Jsf page not rendering in Jdeveloper

Hello. I am using jdeveloper 11.1.2.2. I was working on an application this evening, and added a new jsff page. When I opened the page, I got the "waiting for designer to render" then it stopped, and all I see is white.
I am able to add components to the page via the structure window, but I cannot see what the form looks like in the design view. The the problem started hitting the other jspx form I have in the application.
I read somewhere about someone having the same problem and I tried renaming the windowinglayout.xml, and re-opened jdeveloper, but it did not solve the problem.
This has happened before. I wiped out the system directory, and that works, but wiping out the system directory is painful. Are there any intelligent solutions?
Thank you,
Stuart

I tried renaming the system directory, opening jdeveloper, opening the jsf page -- it rendered. So I then went to the system directory and found the windowinglayout.xml and backed it up.
then I deleted out the new system directory, and the renamed back the old system directory. Found the windowinglayout.xml and replaced it with the good file.
Opened Jdeveloper and the jsf page. Did some work and soon the render failed again.
I am not sure if this is relevant...but the log shows this:

Execute Logic Before JSF Page Is Processed

In my task flow, I have two view activities. When a user executes a specific operation, e.g., click on Submit command, in View A, the JSF page in View B is displayed. View B's JSF page has three ADF components(2 forms and a table) that were created from different view objects in the Data Control section. Before the JSF page is loaded, a method will execute the necessary logic for the three ADF components. Is this possible?
I am using JDeveloper 12.1.3. I am not able to determine where I can specify the name of the name of the method that will be invoked before View B's JSF page is invoked.

You can add a method call in between when you navigate between A to B in your Task Flow.
You can get some idea from this link :
Johny's Tips: ADF: How to execute the ViewObject with a ViewCriteria on the PageLoad in ADF Web Application

Same JSF page is being displayed after submitting form

I have a situation where some of my JSF pages occassionally misbehave. For example, sometimes when I click a <h:commandButton/> (which is located within a <h:form> tag) the action which the button is wired to is not executed. Instead the same page is displayed.
Please note that this glitch happens intermittently with no fixed pattern.
It is also interesting to note that the data which the user enters (prior to clicking the button) on the JSF form is also lost and has to be re-entered again by the user.
Functionally, this is only a minor problem however from a usability perspective this is a major major problem!
I have tried:
Adding <h:messages /> components to jsp pages in order to see if there are any errors.
Verified the spelling of the outcomes ("success", "cancel") in my navigation rules and in the action methods.
Verified the spelling of my bean in the definition as a managed bean in the faces-config.xml file and in the jsp page.
Verified the name of my action method, in the jsp and in the backing bean.
Checked by logging if the action method is reached.
Used the jsf phase tracker to print life cycles phases. However, when the page "misbehaves" this misses out all the application level phases i.e only phases restore view and render response are actually passed.
Created getters and setters for all bean attributes
I am desperate to fix this. Has anybody found a solution to this problem? Please let me know!
Thank you.

I am using JSF version 1.1 and the application server I am using is BEA WebLogic Server 9.1.
The page is one in a series like a "bread crumb" trail or in the style of a wizard if you like. The user goes from one page to the next and can go back if he so wishes.
I have a user form. One part of the form requests the user to enter an email address and then click an "Add" command button. However, sometimes instead of adding the email address to the data table the same JSF page is displayed when the button is clicked and all the data is lost, resulting in the user having to re-enter all the information on the form again!
Hope this helps.
