ADF Faces : Oracle Chooses Flex

hi
On the home page on http://flex.org/ it says "Check out how large companies like ... Oracle ... and others use Flex ...".
Which lead me to find ...
- "Oracle Chooses Flex (part 1)"
http://www.jamesward.org/wordpress/2007/11/12/oracle-chooses-flex-part-1/
- "Oracle Chooses Flex (part 2 - BI Publisher)"
- "Oracle Chooses Flex (part 3 - Enterprise Manager)"
- "Oracle Chooses Flex (part 4 - Siebel CRM)"
- "Oracle Chooses Flex (part 5 - Sales Prospector)"
- "Oracle Chooses Flex (part 6 - Sales Library)"
- "Oracle Chooses Flex (part 7 - Sales Campaign)"
Also, Frank Nimphius has commented on Flex before, "Re: JDev 11 - should we start to learn Flex and ActionScript ?".
Could someone from Oracle please remind us how all this fits in with the direction JDeveloper 11g is taking with ADF and ADF Faces?
many thanks
Jan Vervecken

The standard UI technology for the Fusion apps user interface is the ADF Faces Rich Client components. This hasn't change and is the way most of the teams are developing their new applications.
In an organization with 70,000 people it is a bit hard to make sure that all the project follow the guidelines. Unfortunately out of the about 150 projects we are building, there were a couple of projects that diverted from the standard recommended technology stack. Some of these projects are planning a migration to ADF Faces.
Oracle continue to believe that ADF Faces RC combined with the ADF framework back-end provides the most powerful development experience.
As far as adopting Flash - you can actually see that some of our components in 11 use Flash as a one of the possible rendering technologies - check out the graphs provided by ADF data visualization components for example.

ADF Faces: oracle.adf.view.faces.CHANGE_PERSISTENCE

Does anyone have any information about oracle.adf.view.faces.CHANGE_PERSISTENCE. This appears to be un-documented.

This may help explain the situatin. I originally had JDeveloper 10.1.3.2 installed when I started this tutorial. I then installed JDeveloper 11 version 4 and tried to work the WebCenter Protlet tutorial. When I did it tried to migrage my settings. However, when I attempted to do the tutorial I noticed that it did not have the same options for the WebCenter new applications that would create a Portlet folder. So, I went back to 10.1.3.2 to work the tutorial. No error was flagged at this point but that is when the problems started occuring. I browsed my working directory (C:\Oracle\jdevinstance) where I had my applications stored (C:\Oracle\jdevinstance\mywork) and I noticed that I had what appared to be possible conflicting system files. I had the following system files listed under the working directory: system, system11.1.1.0.17.45.24, system11.1.1.0.22.47.96, and system11.1.1.0.22.49.49. I don't know if this is the issue or not and any feedback about these extra files would be apprecaited?
In addition, I create a new application (using 10.1.3.2) with a different applicaiton directory (C:\Oracle\jdevinstance\MyWork_10.1.3.2) and started the tutorial over. This time I had no issues with the JSP page and all of my web.xml files are the same version (2.4).

ADF Faces showDetailItem seems to "load" child elements twice on tab select

Problem Summary:
Child elements of showDetailItem are being loaded/executed twice. The parent of the showDetailItem is a showOneTab, and the child of showDetailItem is an af:objectImage, which calls a servlet I have written that outputs an image.
The problem I am having is that when I click on a tab (showDetailItem) my servlet is called twice. It is as if the af:objectImage line of my JSP is executed twice.
I have proven this with breakpoints in the servlet and printing a message to the console. The doGet() method of my servlet is called twice. Using breakpoints in the JSP I see the JSP is executed/read only once.
Details:
I am requesting help with this problem as I cannot solve it one my own. I have tried the following, but have had no success.
1. Searched the web for a similar problem.
2. Searched this forum for a similar problem.
3. Consulted the ADF Developer Guide version 10.1.3.0
4. Upgraded my version of JDeveloper to 10.1.3.2.0, which has ADF Faces (oracle.faces.dt) version 10.1.3.40.66.
5. Debugging with print statements and stepping through JSP and servlet code.
6. Created the simplest JSP possible that I could still produce the problem with.
The Scenario:
My goal is to use the ADF Faces showOneTab and showDetailItem tags to create two tabbed panels that will contain a blank tab (tab one) and an image (on tab 2).
I have written a servlet, BrowserImage, which takes and ID as a parameter retrieves a BLOB from view object and then outputs a jpeg image to the browser. This is done by using the af:objectImage tag and specifying my servlet in the source parameter. The image is displayed fine, but I don't want the servlet to be called twice for performance reasons.
Here is the simplest JSP that contains the problem.
Note: I tried to simplify even more by calling the servlet in different ways (jsp:include etc..), but was unable to produce the problem. I think it is key that I call the servlet using an ADF Faces tag (af:objectImage).

      </af:form>
    </afh:body>
</afh:html>
</f:view>Note: The Java Script code included in the JSP is used to get an application module instance and pass it to my servlet in the session scope, so my servlet can access a view object, which contains the BLOB to output. I thought I should explain this as it may look confusing.
Any help would be appreciated.
Thanks,
Mark

I don't think adding a flag to my servlet will work. I left out some details in the original posting that will likely make the flag solution unusable.
It is true that when I click on a tab that my servlet is called twice. My main goal is to ensure that the BrowserImage servlet only called when truly needed. The part I left out of the original posting is that if I click on a tab for the first time I can see my messages in the console indicating it was called twice.
. BrowserImage severlet called (doGet)
. BrowserImage servlet called (doGet)
The key is if I click on the tab again I only see the message appear once.
. BrowserImage severlet called (doGet)
At first I thought this was the correct behavior, but I now feel this is wrong as I think the image is being cached locally on the client browser by ADF Faces, so the first call to BrowserImage is not made, but for some reason on the second "load" of the panel the BrowserImage servlet is called.
To summarize the new details, I still think the showDetailItem is "loading" twice, but BrowserImage is only being called once, because the first loading used a locally cached image. This is my best guess, I did not prove this 100%. I did prove that the image is shown on the page before my servlet outputs it this made me start thinking about the client cache. Also I think it is an ADF Faces specific cache because if I use the "img" tag I don't think caching is used and the image is output by the call to my servlet. I don't want to use img for two reasons, 1 I would d like to use the client cache, 2 the img tag will not stay inside the showDetailItem, showDetail Item needs af: components as children it seems.
So the reason I feel this problem can't be solved with a flag is because I think the image will be cached on the client side and if the showDetailItem is loaded twice it seems my servlet is called once, but it was not required to be called to render the image. I can't use the concept of checking for the servlet being called by the same session in very quick succession, because the real problem I am trying to solve is the servlet should not be called at all, if the client cache had been used.
Perhaps there is a way for my servlet to determine if the client cache was used, but I have no idea how.
I should also point out I am displaying images in a table instead of a showOneTab using the same servlet and technique and the client cache is always used correctly, the BrowserImage is only called if the image is not cached on the client. This is why I think this is a showOneTab problem.
Sorry for leaving out these details, but I did not want to confuse the original posting with too much info. I figured if the tab was only loaded once, the cached image would be used and all would be good.
Again if you can provide more help I really appreciate it.

How to set the target of af:commandLink in Oracle ADF faces ( af:menuTabs )

I try to use tabbedpane component from Oracle ADF...As I found, they stated that only <af:commandLink> can be child of <af:menuTabs>
I want to press the tab then the result can be show at the bottom of that tab...as same as the jsf demo from SUN.
<af:menuTabs binding="#{editor.component}">
<af:commandLink text="Quick-Info" action="#{action.qinfo_page}"
selected="true" />
<af:commandLink text="Vertrieb" action="#{action.vertrieb_page}"/>
<af:commandLink text="Wichtig" action="#{action.wichtig_page}"/>
<af:commandLink text="Kontakt" action="#{action.kontakt_page}"/>
<af:commandLink text="Notizen" action="#{action.notizen_page}"/>
</af:menuTabs>
Now when i press to each tab, it will redirect to new page as i define (such as the code in welcome.jsf...then it redirect to qinfo.jsf when i press at Quick-Info tab).
Pleas help me to solve this problem...I need to show the result at that page (area below the tab). Thank you in advance.

We're sorry, but this isn't supported. One rationale is that it's not generally sufficient to simply reload the target page; you also have to reload the tab control itself to show the new selection. We generally recommend not using frames in this circumstance, instead putting the menuTabs and the content on one page.
(BTW, "target" isn't really supported on <h:commandLink> either)

Oracle ADF Faces Components, Early Access Release 8 is now available

Oracle ADF Faces is a rich set of user interface components based on the new JavaServer Faces JSR (JSR-127). Oracle has been actively involved in this JSR since its beginning. The Oracle ADF Faces Components provide various user-interface components with built-in functionality - such as data tables, hierarchical tables, and color and date pickers - that can be customized and re-used in your application.
ADF Faces also includes many of the framework features most needed by JSF developers today:
* File upload support is integrated at a component level.
* Client-side validation is automatically derived from Validators and Converters for an improved user experience.
* A pageFlow scope makes it easier to pass values from one page to another.
* A new hybrid state saving strategy gives developers the best of both client and server-side state saving.
ADF Faces ensures a consistent look and feel for your application, allowing you to focus more on user interface interaction rather than look and feel compliance. The components support multi-language and translation implementation as well as accessibility features. ADF Faces Components use Partial Page Rendering (PPR) offering superior runtime interactivity. PPR allow the browser to just render a piece of a page instead of the entire page.
The intention with this early access release is to give developers/architects an opportunity to evaluate JSF and Oracle's JSF component offering.
Oracle ADF Faces Components can be used in any IDE that support JSF, including Oracle JDeveloper 10g.

Oracle ADF Faces integrated in Oracle JDeveloper: Freebie?

Hi room, I'd like to ask if Oracle ADF Faces, the version integrated in Oracle JDeveloper (this is a freebie) is a Freebie also, any1 knows, do share. Thanks a lot.

Hi,
no, it isn't. If you are looking for free software, have a look at MyFaces Trinidad, which is the open source - and thus free - version of ADF Faces

Oracle Maps and ADF Faces integration

Hello,
Developing ADF Faces application with integrated JavaScript Oracle Maps I came across a problem.
I have Search Form on my JSF page that searches for some object. I want to pass the object's ID to a backing bean that connects to database, uses Oracle Spatial function to locate object via ID and calculate X,Y position for Oracle Maps.
On the page I want to use setCenter(X,Y,srid) but I don't know how to get those parameters from backing bean or how to access JavaScript object on the page from backing bean.
Any help?
Branislav

You can probablly write a reusable javaScript setCenter() function that takes the x,y as parameters. Note your setCenter() function will need to set the center and also call mapview.display() so that the map will be actually refreshed in the current preview release (this will be made easier in the next preview release of MapViewer).
Then, during the render-response stage of your search form, where you are creating the result table to be displayed to the user, you can add a click button to each row that says 'center the map on this feature'. Then prewire the 'onClick' function of each button to invoke the setCenter() function above, using the corresponding (x,y) that is in the backing bean of your search results.
thanks

Deserialization in Oracle ADF Faces

Hi, All,
is there any algorithm for deserialization (creating components from markup in string) in Oracle ADF Faces? Most part of UI is created dynamically in PL/SQL functions, so I'm not enthusiastic to develop a parser.
AFAIK in Bindows framework they use such code pattern (javascript):
try {
var d = new BiXmlDocument;
d.loadXML( "<root>" + server_create_markup() + "</root>" );
} catch( ex1 ) {
alert(ex1.toiString());
if( d.parseError.errorCode != 0 ) {
alert( "parse error" );
return;
try {
Bindows_component.removeAll();
var de = d.documentElement;
var cs = de.childNodes;
var rp = application.getAdf().getXmlResourceParser();
for( var i = 0; i < cs.length; i++ )
Bindows_component.addXmlNode( cs, rp );
} catch( ex2 ) {
alert( "Error loading markup from DB-server function" );
return;

Hi,
not that I am aware of. However, since ADF Faces is nothing else than JavaServer Facse UI components you can Google for such a parser. If you find one you will be able to use it with ADF Faces too.
Frank
Ps.: Maybe APEX (Application Express) is the better technology for you to use. Its PLSQL based and knows how to create Ajax style applications out of the database.

Does Studio Creator support Oracle ADF Faces and other components?

Hi everyone
According to:
http://www.oracle.com/technology/products/jdev/htdocs/partners/addins/exchange/jsf/doc/faq.html
"Although ADF Faces is "vanilla" JSF we have not been able to run with Java Studio Creator Build 04.06.2. We are working with Sun to resolve the issues in Java Studio Creator."
Does anyone know if Oracle ADF faces now work with Studio Creator and if so which version.
In addition I am also looking for JSF visualization components. In addition to advanced 3-D graphs (send as PNG to client) I am also looking for components to visualize the structure of a website. These all need to work with Studio Creator.

Importing 3rd party libraries used to be complicated. The .complib stuff was added precisely to make it easy.
It does make packaging slightly harder for third party -vendors-, since there's one extra step, but this makes everything easier for (the much larger number of) users of the third party components, since the packaging format specifies a bunch of stuff that we used to have to ask of users when trying to add the jar and associated metadata into the IDE.
The complib stuff is documented, so if you're producing a 3rd party JSF library, or if you really want to use one that hasn't yet been packaged, you can do the steps yourself.
See http://wiki.java.net/bin/view/People/EdwinGoei -- the first couple of links describes the process. Yes, we're working with third party vendors to get this done for their component sets, and yes, there's talk with other IDE vendors to standardize all this.

ADF Faces: !-- ERROR: could not create stylesheet for oracle-desktop.xss

Hi,
I'm using ADF Faces EA6. Sometimes when I create the EAR, it doesn't include the file "oracle-desktop-ea6-ie-6-windows.css" which muest be present in the "adf/styles/cache" directory. If I check the source code from the browser, it starts like this:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"><html dir="ltr" lang="es-ES">
<head><title>Sistema de Seguridad</title><meta name="generator" content="Oracle ADF Faces"><script type="text/javascript" src="/fmv/adf/jsLibs/Commonea6.js"></script><script type="text/javascript">_defaultTZ()</script></head>
Please note the comment: 
Does somebody know the reason?
TIA,
Brian

If everything is set up properly the css will get generated if it doesn't exist. You do not have to be running in the IDE for the css to be correctly generated. Running the app first is generating the css before you deploy, so you've taken away the symptom but not solved the problem. If you try running on another browser, for example, you'll probably run into the same problem.
Does your ear get unzipped when you deploy? Do you have a writable file system for the css to get written to? There is a known issue with WebLogic where it doesn't expand the EAR.
Please check to see if there are errors in the logs.

Oracle.adf.faces.STATE compressed?

Dear all,
i have a question about how adf faces saving its view sate.
in jsf (1.1_02), i can specify a context-parameter com.sun.faces.COMPRESS_STATE=false to avoid compressing the state information.
adf faces seem store the view info in a hidden form field "oracle.adf.faces.STATE"
is there any similar parameter in adf faces?
or adf faces don't compress the state info?
thank you.

Latest version of Oracle ADF Faces?

What is the latest version of Oracle ADF faces? Is there a single place where you can always download the latest and greatest?
I have the API and Impl libraries (and the adfshared too) from JDeveloper. They are part of Early Access 19 I believe. But what version of ADF is used in this demo (link below) that is included with the adffaces-skin.war file? Would EA19 be more recent and work with it?
http://www.oracle.com/technology/products/jdev/101/howtos/adfskins/index.html

Oh, and I will mention, in the version that comes with the skins demo, the manifest file says
Implementation-Version: 10_1_3_0_4
In the version that comes with JDeveloper, the manifest file says
Implementation-Version: ea19
Which one is later?
