Business components wizard still querying

Hello,
I'm running JDeveloper 10.1.2. and have following problem. I had setup new connection to my database(Oracle 9i) and everything looks ok. I can see all schemas and tables. But when I run Business Components Wizard and choose setuped connection then wizard still querying database objects and find nothing. I can only see schemas but no tables. Could somebody please help?

Business Components Wizard and Turkish Characters

Hi,
JDeveloper Business Components wizard produces source code which includes turkish characters. For example entity class created for table named TIP is Tıp. Actually in Turkish lowercase for I is ı but I would like the source code to be produced with i instead of ı("Tip"), since we develop our code in English. Is there any way of doing this. Making wizard work with english language.
Thanks in advance...

Creating Business Components from Teradata tables

I'm trying to use the "business components from tables" wizard using a connection to a Teradata database. The business components get created without attributes. I'm getting an error where JDeveloper thinks that the Teradata table doesn't have a primary key. But I explicitly created the primary in the table (not be confused with a primary index, which is a different object from a Primary Key in Teradata). Am I really not supposed to use ADF to deal with Teradata data stores? I was hoping ADF would be able to work with databases other than Oracle. Is there maybe something special that needs to be done for the business components wizard to be able to recognize the primary key in the Teradata table? If we need to create all Teradata business objects manually then ADF isn't a goo option for Teradata.

I'm connecting via JDBC Generic. I'm using Teradata's JDBC driver. From a connection perspective everything works fine. I have the Teradata connection both as an IDE resource as well as an Application resource. When I expand the application connection it shows all schemas. I then expand my personal schema where I created the table with which I'm testing. It shows my table, all the table's columns, and under constraints it shows the table's primary key. But when I try to create the business components is when it somehow doesn't seem to recognize the table's primary key.

Intermittent bug: Business Components from Tables wizard exception

Hi JDev team
Just to flag an exception I periodically get in JDev 11g TP with the Business Components from Tables wizard, once I've pressed Finish in the wizard:
java.lang.NullPointerException
     at oracle.jbo.dt.ui.pkg.PKEntityThread.createRelatedViewLinks(PKEntityThread.java:1085)
     at oracle.jbo.dt.ui.pkg.PKEntityThread.createTableViews(PKEntityThread.java:966)
     at oracle.jbo.dt.ui.pkg.PKEntityThread.createObjects(PKEntityThread.java:424)

     at oracle.jbo.dt.ui.pkg.PKEntityThread.run(PKEntityThread.java:396)It is raised when the dialog displays showing the work JDev is doing after completing the wizard to create my business components.
I'm not able to consistently reproduce this issue, though I've encountered it several times. Don't quote me, but it appears to happen the first time I use the wizard in a new JDev session, but is not reproducible again in the same session. However it doesn't always happen when I restart JDev and I'm sorry I can't be more precise.
Hopefully the exception trace will give you enough information to track this issue down.
Regards,
CM.

Hi Ric
Unfortunately not really, it's a basic schema we use to test new software. One unusual thing is a hierarchical fk on the same table. But as I said the exception doesn't always occur, but annoyingly does seem to occur when I'm demoing the 11g TP version to clients. I was just hoping the stack trace would help out.
I'll keep an eye on it and if I can work out why it's occurring I'll update this post.
Thanks for following this up.
Cheers,
CM.

QST: Business Components from AIA Enterprise Business Service

Hi,
I'm new in ADF context. Ordinary I work with Oracle SOA Suite and AIA. We have a use case for customer with system integration over AIA. Now we will build a ADF Web Application and I found the "Business Components from AIA EBS".
- Will this wizard work with AIA 3.0 aka 11g?
- How to use this wizard? I save WSDL of EBS to local directory, but can't continue the wizard.
- Is it more compliant to use "normal" was of ADF and invoke Requester ABCS?
Bye
Marcel

Hello Robert,
I know this thread is quite old but I'd like to know whether anything has changed since then regarding the AIA Composite Application Framework extension? I've installed the extension (v 2.4) from a local zip archive (as installing through the update center failed - said it was installed but there was no new options under the Business tier) in Jdeveloper 11.1.1.1.5, had to change extension's paths to modules but still a wizard doesn't want to go to the next step, no error popup, no error in logs, nothing. Does it mean it's still not ready? According to the below site my environment fulfill all the requirements:
http://www.oracle.com/ocom/groups/public/@otn/documents/webcontent/131167.xml
What is the preferred approach for an UI integration then? A requester ABCS seems to be an overhead and misconception to me but maybe I'm wrong :)
Thanks,
Piotr

Business components Clob

I tried to modify a query for a View Object. The modification is just adding a property in the SELECT. I tried to modify the query manually or by using the Query Builder. I have an exception that I don't understand:
Business Components: Java type java.sql.Clob referenced by TopDescrEn is currently not supported.
and the associated SDO schema file is now empty.
I checked in the database and the data type is Clob.
JDev 11.1.1.6

The Standard Entity Beans are a component (JavaBean) that can be a small piece of the ultimate application needs.
Oracle Business Component for Java is a complete framework that has numerous features that make developing COMPLETE applications easy.
Please download the white paper on Business Components, try your hand at creating an application with Business Components (using the wizards) and you will see that Business Components for Java is much more than a simple (/complex) reusable component, it is a complete framework which maked developing N-tier applications almost trivial by allowing you to focus on writing your business logic while the framework takes care of all the application infrastructure and the necessary plumbing.

Can not see the menu of New Business Components Package in jdeveloper

I am just follow the developer guide.
and when I create the Business Components Package, the guide said that
========================================
In the JDeveloper Navigator, select the OA Project where you want to create your package.
From the main menu, choose File > New to open the New Object Gallery.
In the Categories tree, expand the Business Tier node, and select Business Components (BC4J).
In the Items list, select Business Components Package to open the Business Components Package Wizard. You can also right-click on the OA Project and select New Business Components Package to navigate directly to the Business Components Package Wizard.
=====================================
In fact I can not see the menu about Business Components (BC4J) in the File/new/buisness tier/Business Components (BC4J).
I can only see the File/new/buisness tier/ADF Business Components.
And can not find the "Business Components Package" under ADF Business Components either.
I am using the JDev Extension for OA (p5856648_R12_GENERIC.zip) and EBS 12.0.0.
And I create an OA Workspace and OA Project.
can anyone help?

NO Links or Associations created with the "Business Components From Tables"

Hello,
I have a strange problem. I'm working on a Fusion Web Applicaiton. In the Model project, I try to create some Business Components from Tables with the help of the provided wizard.
I select one of my IDE Connections, and I choose two of my tables as Entity Objects (*PATIENTS* and COUNTRIES - more details about them bellow), and also as Updatable View Objects. For Read-Only View Objects I select some other tables, afterwards I choose to create a default Application Module, and I press Finish without creating a Business Diagram. Everything works perfectly except of the fact that the wizzard has created everything but the Links and the Associations between my tables.
To be more precise, COUNTRIES is a simple table, only two columns - ID and NAME, and PATIENTS has some columns like ID, NAME, ADDRESS, DATE_OF_ADMISSION, COUNTRY_ID, where COUNTRY_ID is a foreign key to the COUNTRIES table. Both columns, PATIENTS.COUNTRY_ID and COUNTRIES.ID are NUMBERs. I was expectig the wizard to create a Link and a Association for this foreign key constraint I have between this two tables.
On the other hand, following one of the tutorials I've found, *"Developing RIA Web Applications with Oracle ADF"*, I've noticed that when I was creating Business Components from Tables based on the HR schema, all the Links and Associations were created as they were expected. I've also tried to create the same Business Components from Tables in my own project, and all the Links and Associations were in place. Somehow, it's not working for my particular schema (the one that contains PATIENTS and COUNTRIES).
Is there something I do wrong? I've made sure that all the FK constraints are enabled, alive and kicking. From my point of view, the tables are working and behavig as they should, but I can't understand why that feature of automatically creating the Links and Associations works on the HR schema but not on mine.
Please help!
Bogdan.
PS: I am using Oracle JDeveloper Studio Edition Version 11.1.1.1.0, Oracle SQL Developer Version 1.5.5, and Oracle 10g Express Edition installed on localhost.

Hello John,
Of course I can post the scripts.
The schema name is "TEST". But you should know that there are some extra columns in the PATIENTS table, I've not mentioned before. As you can tell from the scripts bellow, the PATIENTS table has the following columns: ID (number), NAME (varchar2), COUNTRY (number), GENDER (number), ADMISSIONDATE (date), DIAGNOSTIC (number), FIRSTNAME (varchar2), SALARY (number). There are actually 3 FK constraints, I've only mentioned one for the simplifying the example. The first FK constraint is towards COUNTRIES, the second one is towards GENDERS, and the final one is towards DIAGNOSTICS. All this 3 tables have only two columns (ID as number, and GENDER as varchar2). I will post the scripts for all.
Here is the output of the Export DDL to Clipboard from SQL Developer for the COUNTRIES table:

Help required building ADF-Swing/ADF-Faces using ADF Business Components

My question is in regards to how you can go about building a light swing application to an ADF model?
In particular if I were to say that we were developing a 3-tier project whereby we had a database tier, a series of EJB-ADF façade session beans to the database (middle-tier), and a swing client communicating with the session beans (view-controller tier), how would you go about developing these screens?
In particular can we develop these screens using ADF-Faces and also ADF-Swing?
The EJB session façade beans of course are ADF app modules with customised methods. The methods would return back customised DTO objects. These DTO objects are wrappers to row objects ADF would create. This would be mainly due to making these facade beans web service enabled (Oracle state that these methods cannot return oracle.jbo objects if they are to be web service enabled).
This would be typically deployed to an app server, like Oracle App Server 10G.
Could you please have a look at this, as I am doing a lot of research into this.
eg. Taking example from oracle magazine sept/oct 2006
with slight enhancements
package oramag.frameworks.example.common;
import oracle.jbo.ApplicationModule;
import oramag.frameworks.customdto.EmployeeDTO;
public interface HRService extends ApplicationModule {
void deleteCurrentEmpAndCommit();
EmployeeDTO findEmployee(int employeeId); // new method
import oramag.frameworks.customdto.EmployeeDTO;
public class HRServiceImpl extends ApplicationModuleImpl {
public void deleteCurrentEmpAndCommit() {
Row empRow = getEmpView().getCurrentRow();
if (empRow != null) {
empRow.remove();
getDBTransaction().commit();
public EmployeeDTO findEmployee(int employeeId)() {
EmployeeDTO employeeDTO = null;
EmployeesImpl employees = getEmployees();
employees.setNamedWhereClauseParam("EmployeeId", employeeId);
employees.executeQuery();
if(employees.hasNext()) {
EmployeesRowImpl employee = (EmployeesRowImpl)employees.next();
employeeDTO = new EmployeeDTO(employee);
return employeeDTO;
public EmployeesImpl getEmployees() {
return (EmployeesImpl)findViewObject("Employees");
Now given the above code snippet, how could you turn this into an ADF-Swing/ADF Faces application so that if a user using the swing application enters an employee id, then the application will execute the query on the app server, the app server in turn returns the results to the client, and the client finally display the results. Typical MVC example.
Cheers
Rodney

The tutorial is for ADF BC used with JavaServer Faces.
While the tutorial doesn't cover it, we also support drag and drop development for Swing and visual WYSIWYG layout for Swing panels and windows, too. For a very simple example, watch screencast #4 on my blog here:
http://radio.weblogs.com/0118231/stories/2005/06/24/jdeveloperAdfScreencasts.html
One thing I have noticed is that when using ADF business components, when the app module returns a custom DTO object like the above example, it returns the data in a element structure according to the data control palette.
You don't generally ever need to create your own custom DTO's when working with ADF for use by client UI's. The only situation where can be necessary -- until we simplify this in the JDeveloper/ADF 11g release -- is when you desire to expose custom methods that can return sets/arrays of typed row structures through a web service. However, web services are not involved/required in building 3-tier Swing applications.
When dropping onto a page it does so like a string and doesnt give option to display the data in a read only form etc. Is there anything we need to do, to get the functionality.
It's more of what you don't need to do :-)
Just leverage the active data model that the ADF application module provides. You can read more about it in section 4.5 "Understanding the Active Data Model" of the ADF Developer's Guide for Forms/4GL Developers on the ADF Learning Center at http://www.oracle.com/technology/products/adf/learnadf.html). Your UI's bind to view object instances in the data model, and your UI's are automatically kept up to date without needing to write methods that return data. I short article I wrote that preceeded my writing the ADF Developer Guide content on this topis is here:
http://radio.weblogs.com/0118231/stories/2006/01/26/theAdfBusinessComponentsActiveDataModel.html
I know that when dropping a view object you get this functionality. Also was wondering if we were to pass an object of thios type back to the model it might not give us the rich functionality like input forms, like what Oracle provides if we were to drop a enitity view object.
Just use the active data model and everything becomes totally easy, with no changes required to switch between local or three-tier deployment configurations.
Trying to do everything with hand-coded DTO beans is really going the hard way.
Could you help us regarding this?

Adf business components n Ejb Concepts

peoples. sorry for asking this silly doubts.
reason behind this question.
most often use the adf business components i doesnt know it. but now i am learning with help experts blogs. In some blogs, peoples using Ejb concepts.
but ,some what i know ejb.
My doubt:
for desiging an transaction oriented projects. and multiple peoples work on my form.
what should i use.
ejb or adf business componets. which is suitable for the transaction orientation.
please guide me.....

Either is suitable for transaction semantics.
Which one you choose would likely depend upon your background. If you are already well versed in EJB/JPA, then you would follow that approach. If you are already versed in ADF BC or Oracle Forms, then ADF BC would be a logical choice. I will also say that Oracle seems to have invested more effort in the ADF BC side of things, so if you are still undecided, then maybe that observation can sway you to the ADF BC side.
