JSF ADF Faces + database

We have to build a project where we use JSF technologie + database (select,insert,update,delete).
In the past it was very easy to use database + jsp pages. It was just drag - dropping from the data palette (JDeveloper 10.1.2) But with JSF (JDeveloper 10.1.3) it appears to be impossible to get a easy method of working with a database (concerning inserting,updating, deleting).
Who can help us. Because the info concerning database usage and JSF is or a total chaos or insufficient.
We only want an easy,simple working example or tutorial so that we can learn it step by step. (We have tried the examples on www.oracle.com but they appeared to be useless)
Any info or comment is welcome.

In the 10.1.3 preview version of JDeveloper Oracle ADF is missing. Oracle ADF is what allowed you to easily bind JSPs to data sources.
In the production version of 10.1.3 ADF will be there and you'll get the same experience as you get now with dragging and droping from the data control onto your JSP.
For now you'll have to build this manually.
Here is a short how-to to get you started with a JSF connected to a database table using TopLink:

JSF/ADF Faces - ADF-BC example/howto?

Hi,
Background:
==========
I know that ADF-BC databinding is not included in the JDev 10.1.3 preview.
I read and searched nearly all howto's, examples, blogs on ADF-Faces available on the net.
For the past months I learned how to use the ADF-BC with JClient.
This convinced me to use the ADF-BC and it's binding features (a fantastic framework!!!!) for my model layer.
I'm developping a web application.
Most of the examples on ADF-Faces/JSF are on the View Layer.
My question:
===========
I read somewhere that JDev 10.1.3 production with drag and drop of ADF-BC databinding will be available only in the summer.
Question 1:
==========
I suppose that meanwhile it is still possible to use the ADF-BC as the model layer for JSF or ADF-Faces, but the databinding must be done manually, is this correct?
Question 2:
==========
If answer to 1) is yes.
Where can I find a howto/best practice document that explains how to use ADF-BC with JSF/ADF-Faces in the backing beans?
My purpose is to develop my code so that it will be "standard" / "compatible" with the production version of JDev 10.1.3.
I prefer to use the de-facto JSF standard and code the bindings manualy instead of using Struts with available drag'n drop ADF-BC databinding.
Your advice will be apreciated
Frederic

There is no such document for (1) because we are in the process of delivering design time support for ADF BC integration with ADF Faces, as you mentioned.
Therefore, you could either continue with ADF UIX, ADFm, ADF BC for the time being, or else try out ADF Faces with session scope Managed Beans. In either case, you'll want to convert this later on, when JDev 10.1.3 completes its support for ADF Faces / ADF BC drag-and-drop integration.
Kind Regards.

Information about adf data model's state management in JSF/ADF faces?

Dear All,
i am developing an application with JSF/ADF faces + using
adf data model (EJB, not adf bc)...
i want to know more about state management of adf data model..
1. under what condition, will the data in the binding context
(methodIterator, variableIterator, accessorIterator..etc) be maintained accross
http requests? say browse pageA.jspx, pageB.jspx, pageC.jspx..then do data
in the corresponding pages saved somewhere else until session timeout?
2. how do the binding context data be saved ?? http session?
i can't find detail information in the adf bc dev guide and the adf dev guide..
could anyone give me more information about this?? any better document??
i have asked these question several times...but seem nobody can give me a
full picture about the adf data model's state management....it is quite important
in order to develop good application using adf data model.
my company have brought oracle's support service...can i get these information
through metalink (open a SR) ?? or actually no such information available ??
btw, after playing with adf data model for a few weeks, i do find it is very
hard to learn it... no complete document, information is just by providing example...
adf data model do make:
1. simple logic, supported by adf, more simple in coding
2. simple logic, not supported by adf, more complex in coding
3. complex logic, much more complex in coding...brain damage..
lsp

Hi,
actually, these pages don't explain the state management about the adf data model's iterators?
i want to know the state management of the iterators...for some iterators..it's
state is maintained across requests...
please see my previous post: ADF JSF data binding: why state maintained between requests? that Frank Nimphius said:
"in this case its the iterator that survives the page navigation"...
in the adf dev guide..section 5.5.5..it says: "Upon each request, the iterator bindings are refreshed to rebind them to the
underlying RowSetIterator objects. By default, the rowset iterator state and the
data caches are maintained between requests."
in dev guide, it seems state is maintained for request for the same page, but not
accross different pages. but in fact, the rowset iterator do survive...
any detail document that write down the actual behavior of the iterators?
thank you.

Consuming JSF & ADF Faces Components in Portal Page

I am totally new to Oracle Portal environment and doing some analysis of using Portal in our application.
I was reading that we can create JSP Portlets like adding scriptlets, expression and other JSP & HTML elements.
Is it possible to consume JSF & ADF Faces components in Portal page? I mean, is it possible to create JSF Portlets?

The WSRP provider, which is shipped with Portal 10.1.4, would provide this functionality through the JSF bridge. You need to install Webcenter to get the bridge. This makes me think whether you should use Oracle Portal or rather decide to go for Webcenter as development platform, especially if you have a J2EE background already.

Problems while deploying a JSF/ ADF Faces App to Apps Server 10.1.3.0.1

Dear All,
I built a JSF based application (Using ADF Faces Components) developed in JDeveloper 10.1.3.1.0 (Application Configuration: [JSF, ADF BC]. The application is running fine with the embedded OC4J intance (automatically aunch by JDeveloper).
I am now trying to deploy it on the installed Oracle Application Server (running on the same local machine). The details of the versioning for different components in this App server are as follows:
1. OracleAS J2EE 10.1.3.0.0
2. Oracle ADF 10.1.3.1.0
The deployment steps I followed (as given in Chapter 34 of 'Oracle ADF - Developer's Guide for Forms/4GL Developers') seems to be running smoothly. This is because the deploy process ends up showing no erros in the message window.
However when I tried to test the application with a browser using the Apps Server URL (HTTP://localhost:8888/<my-app>/<firstfile.jspx>), I am finding 'Page not found error'.
I also tried a manual deployment (using deploy to a WAR file then copy the resulting war & ear files and the xml descriptor file to the Apps server's http root) and gives the war file URL in the browser.
In this case now I am getting the following error page:
=====================================================
The XML page cannot be displayed
Cannot view XML input using style sheet. Please correct the error and then click the Refresh button, or try again later.
An invalid character was found in text content. Error processing resource
'http://localhost:8888/HousingWithADF.war'.
=====================================================
Any idea?
Regards,
Irfan Ilyas
PS: I am doubtful about creation of Deployment Descriptors step as the documentation is not very clear about exactly which descriptors we need to create. Using my own idea, I tried to create J2EE descriptor, and one tld (taglibrary) file. However, the manual war deployment generates only the tld file in the deploy folder.

Thanks for the hint.
OBSERVATION #1:
After looking through the administration console for OC4J instance, I found my application name with UP status. When drill-down further, the console gives me the URL which can be used to test the application.
While using the URL, a different error message was found:
URL: http://localhost:8888/KFUPMHousing/
Error:
====================
HTTP 403:(Forbidden)
================
You are not authorized to view this page
You might not have permission to view this directory or page using the credentials you supplied.
From my experience of Microsoft IIS, I know here I may need to configure the folder permissions for a web-user. But exactly which user and where it is defined (at OS Level or in AS), I am not much sure.
Can you elaborate?
OBSERVATION #2:
The log text for my application shows the following error (for the attempt I did with the URL shown above)
Log Text
07/01/05 22:43:38.62 HousingWithADF: JspServlet: unable to dispatch to requested page: Exception:java.io.FileNotFoundException: C
:\product\10.1.3.1\OracleAS_1\j2ee\home\applications\HousingWithADF\HousingWithADF\HosReqInfo.jspx (The system cannot find the file specified)
However, I can browse the file on my local disk in the path specified with a little change in the path. The file is found in 'pages' folder within the last folder,named HousingWIthADF. I tried to move the file in the exact path specified in the log and now finding the 'Page not found' error.
Any idea?

Deploying JSF - ADF Faces (EA14) application to OAS 10.1.2

JSF 1.1.01 problem
I have an ADF Faces application that I have been working on in JDeveloper 10.1.3.0.2.223 and I thought that it was time to deploy it to an Oracle 10g AS (10.1.2) (WindowsXP SP2). A long time ago I did a test deploy of a sample program jsflogin and that works fine (although I now realize that this was a JSF 1.0 application) and my ADF application is, of course, JSF 1.1.
As I've already said, my JSF 1.1 / ADF application works perfectly in JDeveloper. The problem is that the first time the OAS 10.1.2 deployed instance of my application hits a <f:tag> it fails. When the first <f:tag> was <f:loadBundle> the error looked like this:
500 Internal Server Error

I've got all the jsf, jstl, standard, and other jars in my WEB-INF/lib folder and there are no other jsf or jstl jars in the OAS home so I can't be connecting to the "wrong" library.
Any hints? Has someone else out there successfully deployed to 10.1.2?
Thanks in advance, Mark

Okay, so my problem was that the URL I was using was the OC4J launch url (http://host/applicationname and my welcome-file-list was
<welcome-file-list>
<welcome-file>LoginPage.jsp</welcome-file>
</welcome-file-list>
I tried these two variations
<welcome-file-list>
<welcome-file>LoginPage.faces</welcome-file>
</welcome-file-list>
<welcome-file-list>
<welcome-file>faces/LoginPage.jsp</welcome-file>
</welcome-file-list>
and neither of these worked either. (I did restart the OC4J node between each attempt.)
I finally created an index.html file for the application with an automatic refresh content="0;URL=faces/LoginPage.jsp" and this is working.
Should the welcome-file-list have worked? Am I doing something wrong here?
Thanks for the help. Mark

URGENT: ADF Faces table updating issue.

I have a project that uses JSF, ADF Faces, EJB 3.0, and the ADF binding framework.
In this project, I have a page with a databound ADF Faces Table. The table has a number of read-only columns and two read-write columns. I also have an Edit button that allows the user to pop up a dialog box to edit the selected row of the table. When the user clicks OK in the dialog box, the data is passed back to the main page and the table is updated.
Everything works correctly for the read-only columns. For the read-write columns, however, the table data does not get updated following an edit. This is what I have found:
1. The table row data gets passed in to the Edit dialog correctly.
2. The data gets passed back correctly.
3. The model gets updated correctly (up to and including the database).
4. Looking at the iterator in the debugger shows the correct, updated data.
5. When the table row is getting redrawn, the getter calls for the read-write columns return the updated data.
6. As mentioned above, the read-only columns get updated correctly.
7. Updating the read-write columns directly from the table works correctly.
So, the problem appears to be in the GUI layer. I suspect that, somehow, the submitted values of the read-write columns are not getting set properly, but I cannot figure out how to do this.
Note that clicking on the Edit button results in a partial submit. In the return listener, I add a call to AdfFacesContext.getCurrentInstance().addPartialTarget(getRecipientTable()) in order to redraw the table (getRecipientTable() is the bound value of the ADF table).
Please help! We are so close to production and we need to fix this.
Thanks,
Ara

Hi,
I don't have a testcase for this, so I just come up with ideas to try
1. refresh the parent container of the table. It seems that the input text components are not triggered to refresh if the refresh is on the table.
2. If using ADF, make sure the update is performed directly on theiterator (which automatically is the case if you use a ADF bound form for this)
3. Check if executing the table iterator and then setting back the current row makes a difference

ADF Faces (Trinidad?) & Facelets Support

This is long, but help and advice is very much needed.
My programming team is facing a migration from UIX to JSF (ADF Faces) for future applications and we have hit a road block in regards to a template structure that is easy to use and maintain. We had gone through official Oracle training with JSF, however the trainer's answer to templates was to "create a template and copy and paste for every new file". For our team this is unacceptable so I've been charged with figuring out how to simply templates for our team. Not only do we need to make this easy for our application developers but we need to keep it simple for web developers to create "simple" survey-like applications.
From what I've come across the answers seems to be either Facelets or Regions.
Working with Regions seem to be over-complicated, requiring too much replication (basically back to copy/pasting an entire template) or passing the panelPage's content as a java object (bad for our web developers). I presented the combinations to my team and supervisor and it was agreed that Regions are impractical for our development practices.
So it seems the answer is with Facelets. The problems I have with this is that:
1. JDeveloper doesn't appear to natively handle Facelets, or include the libraries.
2. From what I've learned, the ADF Faces library that comes with JDeveloper doesn't have Facelets support either.
3. Looking into Trinidad, Facelets support exists but there is a lack of the Oracle skin.
Facelets support is really what my team needs, as it's the closest thing to the old UIX templates I've seen so far.
I've followed instructions/examples on several posts here, but I've yet to come across an example that works. I've Googled countless pages and examples, but when it comes down to ADF Faces and Facelets, it seems I'm at a dead end.
So, can anyone help me with this?
Thanks in advance,
Rick
PS:
Using JDeveloper 10.1.3.2.0.4066 with stock ADF Faces
External libraries used:
Facelets 1.1.11
Trinidad 1.0.1-incubating

It just so happens that not long after I posted, I catch the "adf-facelets.jar" on the facelets site.
dvohra, I had seen the links you've pasted however none of them described the actual process to get it to work, it's all been segmented copy/paste instructions. This doesn't really help someone who is struggling.
So... I'll paste what my solution was, hopefully this will help others:
1. Download and install the Facelets 1.1.11 library
https://facelets.dev.java.net/servlets/ProjectDocumentList?folderID=3635&expandFolder=3635&folderID=0
2. Download and install the ADF Facelets library
https://facelets.dev.java.net/servlets/ProjectDocumentList?folderID=3990&expandFolder=3990&folderID=0
3. In web.xml add the following:
<context-param>
<param-name>oracle.adf.view.faces.ALTERNATE_VIEW_HANDLER</param-name>
<param-value>com.sun.facelets.FaceletViewHandler</param-value>
</context-param>
4. Make sure your project's libraries have loaded your Facelets and ADF Facelets, as well as ADF Faces Runtime.
5. Begin using UI Components as desired.
Example: http://eugeneciurana.com/pastebin/pastebin.php?show=1308
Extra notices:
I had to comment out the following in my faces-config.xml as it conflicted with the web.xml setting:
<view-handler>com.sun.facelets.FaceletViewHandler</view-handler>
This is what worked for me, I hope this helps others out there.
Thanks,
Rick

ADF/ ADF Faces reading or tutorials

Hi all,
I've been doing Java SE for a couple of years (and would say that I'm pretty good on language fundamentals). J2EE however is pretty new to me. I would like to get up to speed in development with ADF/ADF Faces. I've been looking for some tutorials, but most seem to be ADF and Struts, and I get lost when the instructions get struts specific.
Could anyone recommend any ways I should go about learning and any tutorials that they have found useful?
I've done the walkthrough here http://www.groundside.com/blog/content/SueHarper/, which was a good tutorial, but I could do with a little more detail to help me understand whats actually happening behind the scenes.
Thanks in advanced
Tim Williams

I've been struggling with this as well. I'm trying to use EJB3, JSF (ADF Faces) along with ADF Binding to speed things along but due to lack of documentation I'm unable to progress beyond simple uneditable master/detail pages. There's lots of documentation on JSF, a reasonable amount on EJB3 but none (that I can find) on how JSF and the ADF Binding layer work together (I was expecting the binding stuff to show up as a managed bean or something that I could access programmatically.) There is one short tutorial that uses drag n' drop to create a master/detail app with an EJB3 backend with ADF Faces / Bindings but it doesn't connect all the dots by showing how to perform the updates (ie. hook up a "Save" button to a method on the session facade bean.)
There seem to be two camps generating tutorials at Oracle right now. One camp that does J2EE-only (EJB, JSF/ADF Faces) and another camp that does ADF BC/Faces (Oracle-proprietary) but there are none that do EJB, JSF & ADF Binding (though the docs I can find say that ADF binding is persistence-agnostic.) Thus there are tutorials that cover using Business Components and Binding with JSF (mainly targeted at the Forms folks) and tutorials that cover using EJB3 with JSF but using backing beans to manually connect back to the EJB rather than using the Binding layer provided with ADF.
Does anyone know of a document or tutorial that goes integrates these pieces together? The closest I have found is this one (http://www.oracle.com/technology/products/jdev/tips/muench/1013eabinding/index.html) titled "Selected Highlights of ADF" but it assumes indepth knowledge of previous versions of the ADF so it left me with more questions than answers.

ADF Faces and BI Graph?

Is it possible to use BI Graph with ADF Faces?
So far I was using BC4J/JSP/Struts and to put Graph (<graph:Graph/>) into JSP page was easy - using Data Control Palette. Now I want to migrate to JSF (ADF Faces) but when I create JSF JSP - it is impossible to insert some ViewObject as Graph from Data Control Palette.
Thanks for any clue.
brano

My current solution is:
The ADF Faces main page:
<af:showOneTab position="above">
<af:showDetailItem text="Graph Include" disclosed="true">
<f:verbatim>
<jsp:include page="${pageContext.request.contextPath}/graphs/Graph.jspx"
</f:verbatim>
</af:showDetailItem>
The Graph page:
<?xml version='1.0' encoding='windows-1252'?>
<jsp:root xmlns:jsp="http://java.sun.com/JSP/Page" version="2.0"
xmlns:graph="/webapp/graph.tld"
xmlns:adf="http://xmlns.oracle.com/adf/ui/jsp/adftags">

</head>
<body><graph:Graph data="${bindings.EmployeesView1}"

</html>
</jsp:root>
When I try to run this, I get the following error:

Could you please post the solution?

Validation messages in JSF (when not using ADF faces)

I've spent some time with JDeveloper 11 and would like to use it on an upcoming project. I have to target IE 6, so I won't be able to take advantage of ADF Faces. Instead I'd like to use the ADF Business Components with a standard JSF interface so it can be used by people still running IE 6.
I've created a Business Component from a database table and can bind a JSF HTML Creation Form by dragging the appropriate view from the AppModule in the Data Controls pane. However, when I attempt to submit the page without all the fields being valid I get the following validation error message:
j_id__ctru2:j_id__ctru6: Validation Error: Value is required. j_id__ctru2:j_id__ctru6: Validation Error: Value is required.
I've tried making this more descriptive, but editing the error message in the Validation Rules section of the Business Component has no effect. What's the best way to convey a meaningful validation message to the user when not using ADF Faces?
Also - I'm still very new to JDeveloper. Since I won't be able to rely on my users having Internet Explorer 7, would you recommend I stay with JDeveloper 10? The examples and documentation I've seen so far for JDeveloper 11 appear heavily biased towards using ADF Faces so I'm starting to wonder how much support is there for using plain old JSF.
Thanks for your time!

Hi,
if you are completely new to this then I suggest to use JDeveloper 10.1.3 and ADF Faces in there. Its good to use with IE6 as well. Currently we do have more tutorials available for this release than for 11, which for this reason is a better choice for someone new to this
