ADF and JPA question

I tried the example in 'Build a Web Application with JDev 10g Using EJB, JPA and JSF and it worked.
This example is based on two tables. Now I have 6 tables. Tables 1,2 and 3 are joined to populate an ADF table form and tables 1,2,4,5 and 6 are joined to populate another ADF form.
My question is: should I use JDev to generate all 6 entity EJBs or rather create two Oracle views for each of these joins and get JDev to generate EJB for each of these views?
Also, how can I customize the annotated queries generated by JDev? I would like to have all the native SQLs to be in separate XML files. Should I use XML files generated by JDev or create a new XML file? Is there an example of how to do that?

Hello,
I read somewhere JPA supports external XML native SQL queries and apparently these queries override named queries in entity annotations. Assuming this is true, would that be the preffered way (both queries, 1-2-3 join and 1-2-4-5 join have one input parameter each so the database views would have to be parametrized in that case)? And how should I access these XML based queries from inside the code?
Also, what queries are generated by JDev JPA when 6 tables are selected? Are all combinations based on foreign keys generated or just table (entity) and its directly related tables?
Thanks,
Sale

Clarify ADF BC and JPA

I am a Forms programmer, want to start learning Jdeveloper and java. I read many books and 11g tutorals. I am confused that are there 2 different methods in create database entities?
1. I want to clarify that ADF BC and JPA are 2 different things, is it?
2. if yes, which one is simple and easy to handle?
Thanks a lot !

ADF bc is simple and easy and has lot of features.
And most of all, ADF bc is vastly used in Oracle Applications ERP V1.
Features of ADF bc can be easily compared with forms world. like datablock to EO, LOVs etc

ADF and 100 tables

Hi
I'm new in ADF technology so I suppose my question is very simple.
How can I create ComboBox witch have a fields with all tables in databes??
I don't wont write manually, but I want that my application read all tables from database (JDBC connected)!!
Then if I choose one of them the NavigationBar will be for selected table..
If something is not clear pleas ask me, because my english is not very good :/
Thank you for help.

Shay:
Could you give me more details or links where this is explained??
Sorry but I'm new in ADF and Swing technology..
Frank:
I want to modify, add and erase rows in tables which someone select that table in ComboBox..
For example I want to do something like this:

but in ComboBox I must selected tables with my database!!

ERRORS in the Lab - Developer Day: Oracle ADF and Fusion Middleware Dev

I atteneded the Developer Day on Oracler ADF and Fusion Middleware Development on 11/19. I did the lab (following step by step instructions) and encountered the following errors:
1) Export to Excel (Step 4, actions 5-9) - Got run-time 500 error when run app. I had to skip these steps to be able to continue with the lab.
2) Click on Printable Page (Step 4, action 16) - I looks like it works, but nothing shown up on the browser or printing actually happened.
3) Click on Create Insert (Step 4, action 26) - Got Java.Lang.NumberFormatException
4) There is no lab for mobile application development. Where should I start? [getting mobile plug-in software, lab tutorials]
The instructor said that I could post any questions on the Forum. I hope that this is the correct Forum to post these types of questions. Thanks much in advance for your responses.

Perfect, I get the exact same page when I login, however, this page doesn't have any links to the actual sessions. If I remember correctly, after logging in another window used to open in which we could select the session to play.
Please let me know how I can access the session from the page that is displayed after logging in. Thank you for taking time to check, appreciate your help.

Best Practices for BI, ADF and Oracle Forms installations on Weblogic

Hi, I'm researching options on upgrading to Oracle 11g Middleware. My company currently has Oracle Forms 10g running on Oracle Application Server.
We are interested in using Oracle Forms 11g, ADF and Jdeveloper, and Business Intelligence with Oracle's Weblogic 10.3.5.
Is there any whitepapers or documentation on best practices for installing alll of these components together?
For instance, can ADF ( with JSF 2.x ) be installed in the same domain as Oracle Forms 11g but use different managed servers?
Will Business Intelligence need to be in a seperate Oracle Home with it's own weblogic installation? I spend a lot of time trying to get the JSF upgraded to 2.x in the Business Intelligence installation and could not get it to work.
I know it's a pretty broad question but thank you for any direction on this.

Thanx for the reply! I read through the documents and they are very good at explaining how to install the different components individually. I still can't find much on installing them together. I hope it's not just going to be a trial and error thing.
So far I've installed done the following successfully:
Installed 10.3.5 weblogic
Forms and Reports 11g on top of 10.3.5
I've created an additional managed server for our ADF applications.
My next step is upgrading the JSF to 2.x. I would have to stage patches 12917525 and 12979653. I'm afraid it will break the forms and reports though. Any ideas?

ADFS and BYOD in azure

Hello ,
We are in the process of moving all servers into azure , and deploying BYOD infrastructure hence no need for clients machine to be joined to the domain “obviously”
My question is , if my clients are non-domain joined ? why do I need to deploy ADFS in azure at all ? since no on premise servers anyways

Avoiding Federation Now That Password Hash Sync Is Available
A key driver for federation deployments with ADFS used to be that it enables users to use a single password across on-premises and cloud sessions. However, federation deployments take some effort due to the additional servers and network implementation.
The on-premises servers also have to be Internet accessible through any corporate firewalls in a secure way, and they also have to be highly available since logins are not possible if they or their Internet connectivity are offline. Because password hash sync
is a feature of directory synchronization, it is initiated from the on-premises server and doesn’t incur many of the infrastructure requirements and costs of federation. It only requires a single server and whilst that server requires outgoing access to the
Internet in order to connect to Azure AD there is no requirement for inbound connections, custom firewall openings or highly available configurations.
There are still some reasons why some customers will still prefer ADFS and directory federation over DirSync and password hash synchronization. These include:
ADFS can be configured such that users who are already logged on to a domain joined and connected machine do not require any password re-entry to sign in at Office 365. This gives you true single sign-on since re-entry of the password is not required. With
DirSync and password hash synchronization a user must still re-enter their password, although it will be the same password as they use on-premises.
ADFS allows for client access filtering, which restricts access to Exchange Online to users based on their IP address.
ADFS will honor Active Directory configured login time restrictions for users.
ADFS can include web pages for users to change their passwords while they are outside the corporate network.
With ADFS the authentication decision is always made on-premises and no password hashes are synchronized to the cloud. This may be obvious but can be sometimes a security policy requirement.
With ADFS an administrator can immediate block a user to remove access where-as DirSync synchronizes these changes every three hours. Only password changes are synchronized by DirSync every two minutes.
ADFS permits use of on-premises deployed multi-factor authentication products. Note that Azure AD supports multi-factor authentication but many third party multi-factor authentication products require on-premises integration.
Where Microsoft Forefront Identity Manger (FIM) is required for some other FIM capability. FIM directory synchronization does not include password hash synchronization so ADFS will still be required for SSO login.
Some on-premises to cloud hybrid scenarios require ADFS such as hybrid search.
If you need any of these then Active Directory Federation Services is still the best option.

ADF And/Or JSF : A Shift to Future

Hi All,
I am using Oracle Forms since 1996 and worked in different versions of it. Now there is a move away from Forms to J2EE based solutions like ADF/JSF to name a few. Even Steve is writing a book for Oracle ADF Development for Forms Developers. I have few questions in mind, that
1. What is the best way of learning these technologies means following the book Steve / Grant is writing will help us.
2. One must know ADF before he could learn JSF, Is it a prerequisite ?
3. For a Forms Developer what is a right tool (ADF/JSF) which is closed to form concepts he knows so that the shift could be easy and smooth and after that he can learn more.
Thanks In Advance

You got is a little mixed up - JSF is one technology that the ADF framework uses.
So it is not two options - it is one option.
A great way to start learning development using JDeveloper ADF and JSF is visiting the special center we built for people just like you - Forms developer who want to move to Java.
http://www.oracle.com/technology/formsdesignerj2ee
Try for example the hands-on scripts there.
Then you can continue with the rest of the resource on the JDeveloper home page on OTN.

Jdeveloper, adf and xmp

Dear sirs, i belong to a company that have one ERP, developed using oracle forms.
We are in the process of remake it using JDEV ,ADF, and ADF_BC.
I have a real need, ours ERP costumers have the need to change a lot of the aplications reports, including data fields, well personalize it , etc.
We are thinking of using the XMLP and the JDEV and doing the reporting of ERP by XMLP. My question is can i do the reports (basic ones) combining both technologies, to allow later my costumers to be able to change (if they need) the layout of the reports using XMLP Desktop or any other very basic (easy) technologie).
Well Thanks in advance.
Paulo J. Costa

Paulo,
of course you can do using the Java APIs of XML Publisher. Furthermore there are plans to make XML Publisher the reporting framework for ADF.

How to achieve context passing between ADF and OAF?

Hi,
I have a requirement where I need to access OAF application from ADF application.
Do the necessary transactions in ADF and if needed the results should be displayed back in OAF page, How can we acheive this? Assuming that ADF is SSO enabled and EBS is integrated with SSO/OID. which eliminates user authentication while accessing different frameworks/applications.
Thanks and Regards
Sridhar

Hi,
they don't share the same context, so your options are
a) passing values as a request parameter going from one application to the other
b) storing context information in the database that both share
This question is also better asked on an Apps forum

Difference bw ADF and OAF

Hi,
Can anybody explain to me in simple words, what is the differene between ADF and OAF?
thanks and Regards

What is OAF? What is ADF? Difference between OAF and ADF?
To answer these questions satisfactorily lot of space is required.
In Simple terms for a newbie:
OAF - Java based framework for building html pages in Oracle Apps. Currently being used in R12.
You'll need OAF for extending existing functionality build in R12.
ADF - Java based framework for building html pages in next generation of ERP suite from Oracle, FUSION.
ADF is generic and is also being used for custom development.
ADF is not based on proprietary technology.
ADF can also be used for building custom modules for current oracle apps release R12.
From my personal experience, while learning ADF, then don't treat this as advance version of OAF. Start fresh as if its a new framework. Continuous comparison makes it tough to pick up ADF in initial stages.

Prince

Performance issue and functional question regarding updates on tables

A person at my site wrote some code to update a custom field on the MARC table that was being copied from the MARA table. Here is what I would have expected to see as the code. Assume that both sets of code have a parameter called p_werks which is the plant in question.
data : commit_count type i.
select matnr zfield from mara into (wa_marc-matnr, wa_marc-zfield).
update marc set zfield = wa_marc-zfield
     where werks = p_werks and matnr = wa_matnr.
commit work and wait.
endselect.
I would have committed every 200 rows instead of every one row, but here's the actual code and my question isn't around the commits but something else. In this case an internal table was built with two elements - MATNR and WERKS - could have done that above too, but that's not my question.
            DO.
              " Lock the record that needs to be update with material creation date

Here's the question - why did this person enqueue and dequeue explicit locks like this ? They claimed it was to prevent issues - what issues ??? Is there something special about updating tables that we don't know about ? We've actually seen it where the system runs out of these ENQUEUE locks.
Before you all go off the deep end and ask why not just do the update, keep in mind that you don't want to update a million + rows and then do a commit either - that locks up the entire table!

The ENQUEUE lock insure that another program called by another user will not update the data at the same time, so preventing database coherence to be lost. In fact, another user on a SAP correct transaction, has read the record and locked it, so when it will be updated your modifications will be lost, also you could override modifications made by another user in another luw.
You cannot use a COMMIT WORK in a SELECT - ENDSELECT, because COMMIT WORK will close each and every opened database cursor, so your first idea would dump after the first update. (so the internal table is mandatory)
Go through some documentation like [Updates in the R/3 System (BC-CST-UP)|http://help.sap.com/printdocu/core/Print46c/en/data/pdf/BCCSTUP/BCCSTUP_PT.pdf]

I have purchased music with my old apple id, old computer and old email. My old email and computer are not available anymore and I dont remember my password and securtiy question anymore. How can I authorise my old apple id to authorise the new computer?

Hi, I have a new computer and new apple id. I've purchased music with my old computer, email and apple id.
I cant access now the previously purchase music, because it wants to authorize the new computer to play the
music. I cant remember password and security questions for my old id and the old email doest exist anymore.
What can I do?

Hi, Carmen.
Thank you for visiting Apple Support Communities.
If you need to reset you security questions, do not know the answers and no longer have access to that email account, see the last sentence under Note in step 5.
You'll be asked to answer 2 of your 3 security questions before you can make any modifications. If you are unable to remember your answers, you can choose to send an email to your rescue email to reset your security questions.
Note: The option to send an email to reset your security questions and answers will not be available if a rescue email address is not provided. You will need tocontact iTunes Store support in order to do so.
