Building Cascading Lists for Query with ADF Business components and JSP

I build Cascading Lists for Query Screens with ADF Business Components. When I to select master list first Ok, but when I to select master list second returned error : JBO 25013 : Too many objects match the primary key oracle.jbo.key[CN]. CN dependences with key to detail list (Countries in this case). Please help me.

Why ADF Business Components and TopLink

Hi All,
Why are there two types of components in Businses Tier? (ADF Business Components and TopLink). Even through there are other types, I can visualize the use of other components but ADF Business Components & TopLink seems to serve the same requirement.
Can some one provide me information on what is the difference between these two and when to use which one?

ADF Business Components (aka BC4J) are different from Toplink from approach point of view. Basically if you are more comfortable with SQL and want fine grain control over what and how SQL are run against the database, BC4J is the way to go, because, it's you who write the queries(in ViewObjects)
If you are from more of java backgroup and can visualize things in term of Object and relationships among objects, so on and so forth then Toplink would be the right choice.
Pls see the post by Shay in his blog:

ADF business components and scalability ?

Hello,
I am new to the ADF Framework, I come from an open source background.
I have a limitation to use Oracle technologies for an internet banking design.
My concern is the large number of users accessing the system and how we scale up through clustering.
Do you recommend ADF business components for this application, can ADF be simple POJOs handlers or EJB 3.0 session facades ? if that is the case, would you recommend EJB 3.0 for clustering and scalability for an internet banking system.
Any guidance is appreciated.
Thanks.

Thanks for the reply, I will read the document, however,
If I try to compare ADF to other frameworks, creating BCms as POJOs would take advantage of the Apache clustering(web tier, same as Tomcat clustering in Jboss), there is no need for OC4J services of the 10gAS, on the other hand, if I go with EJB3 stateless session beans BCms then i would need 10g OC4J container and its clustering capability(AS clustering).
Your time is appreciated and please respond only if you time, i will go through the doc.

How to Develop with ADF Business Components for Multiple Databases

Hi,
I developed business component by http://www.oracle.com/technetwork/developer-tools/jdev/multidatabaseapp-085183.html tutorial. it was work on mysql and oracle database. In mysql , Set Up Primary Key Generation is only one sequence share betweeen tables. How to make another sequence each mysql table?

juddi,
As that article states, the built-in capability of ADF BC uses that single table for all entities (tables) - since it's just a surrogate key, it should not matter. If you wanted different sequences for different entities (tables), that is something you'd have to code for yourself.
Best,
John

Concurrence with ADF business components

I need know, how do I do the concurrence control (connection of several users ) on business components

Hi,
concurrency is handled internally within ADF BC. Each user will have their own instances of Application Modules which represent a transaction and implicitly handle row locking and state management.

Best Practices ADF Business Components

Hi all,
I'm reading the Dev Guide of ADF Business Components, and I've some questions:
a) In the business tier, Which is the best way to create new rows in the db? I've found two ways: Using a ViewObject and then call create and insert or using the EntityDefinitionImpl object and call the createInstance2 function.
b) In the business tier, which is the best way to search for a row in the db? I've found two ways: Using findByKey on the ViewObject or using the findByPrimaryKey on the EntityDefinitionImpl object.
Thanks!

Hi,
a) use a ViewObject
b) also I would think its the ViewObject

How execute pl/sql command from Oracle ADF Business Components

can't find examples for how execute pl/sql command from Oracle ADF Business Components and how call pl/sql package procedure from ADF Business Components.
insert,update,delete rows in view object instance cache is good but if i must do some complex operations while insert,update,delete rows..it's more better for me to call
pl/sql procedure from oracle db.Am i wrong ????

Roman,
this should be similar to how it worked in JDeveloper 9.0.3. hava a look at <JDev903 Home>\BC4J\samples\StoredProc for a code example.

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 - Cascading Tables

I am using Oracle Jdeveloper 11.1.1.4.0
I have tried an approach to cascade two tables using ADF Business Components.
A single column is declared as Foreign key.
I have used 2 drop downs. During the value change of the first drop down, the values of second sholud be populated from data base.
How to achieve this using cascading tables.
Kindly help.

Multiple ADF Business Components projects for one ADF project

I have an ADF project where I have my own ADF Business Components Model, with View Objects, etc. Can I add another ADF Business Components from another project - they access a different database than I do with queries that I could use.

I see two options:
1. rename one of your Model.jpr to somthing else and then try again to add a dependency.
2. create a jar out of the second model project and import the applcation module out of the jar into the other project. To import use file->import and select 'Business Components' from the list. Check tho docs ("Importing Business Components Created by Someone Else")

ADF Business Components with SQLITE db connection

Dear Experts,
I just started exploring JDev+ADF. I tried to create business components from a SQLITE db connection, but it seems that the Wizard windows stuck at the first steps even though I have successfully tested the SQLITE db connection.
Has anyone tried to create ADF Business Components from sqlite db connection using the wizard windows? Do I have to code this manually?
JDev: 11.1.1.6
JDBC Driver: sqlitejdbc-v056.jar
SQLite: 3.6.0
Thanks

Since ADF BC are just java classes and jars - I don't see a reason why not.
But I would be interested to know what specifically are you going to build with velocity.
