Creating business components programmatically

Hello,
I've been working with ADF 11g and JDeveloper for some time, and I've found very useful to be able to create programmatically view objects and child application modules without having to declare them "statically" in the application modules where they are used. This comes very handy when you have lots of business logic that shouldn't be exposed to the view layer of the application.
As I though that this could also be useful for other people, I've documented a technique for creating business objects dynamically (and easily!) in [url http://adftechniques.blogspot.com/2011/11/many-adf-projects-have-lots-of-business.html]my blog. There you will find a library and some source code that you can use in your projects, and a small demo.
I hope that you find this interesting and useful.
Regards!

Hi,
thanks for sharing

How to create "Business Components Package" in the Jdeveloper ?

Hi,
I installed and set up "Patch 7523554 10G Jdeveloper With OA Extension ARU for R12 RUP6"
I have ran out the test_fwktutorial.jsp and test_fwklabsolutions.jsp.
All links work properly on these pages.
I created HelloWorld page from "Oracle Application Framework Toolbox Tutorials".
Its works properly too.
Then I started to create "Search Page".
I created "Business Component project" in the toolbox.jws.
I was trying to perform step 2.1 "Create the BC4J Package for Client (UI) Objects".
But I didn't find "Business Components Package" in the context menu.
Could you give me advice how can I create package of this kind ?
Thanks.

I created "OA Workspace" and simultaneously with it created "Business Components Package" <yourname>.oracle.apps.ak.employee.
After this it i necessary to creates one more "Business Components Package" <yourname>.oracle.apps.ak.schema.server
I failed to create Package of this kind.
In the "BC4J Tutorial" It seems to me I found similr actions.
I suppose I may perform next step:
Figure 6-3 http://download.oracle.com/docs/html/A97671_01/wtgbc4j.htm#BABIAIEI
Figure 6-4 http://download.oracle.com/docs/html/A97671_01/wtgbc4j.htm#BABJIIII
But I failed to pass these steps.
Could you tell me, please, how to do this?
Thanks.

Associations and Links does not load when creating Business Components

Hi guys,
I am having a problem when I create my business components from table. Let's say that I start a new fusion web application. I then create my business components, enter the proper database connection settings. After everything is done, I am only getting my entities and my views, without any associations and links.
The thing is that it worked the first time. Everything loaded as it should. I then asked a collegue of mine to try on his computer. Surprise, everything loads perfectly just like it did the first time I did it.
I then tried on one of my linux virtual machine, via the same PC that I am having the problem. Again, the same problem, even if this is another JDeveloper instance (vm).
I have read the thread 2187263 that mentions to re-create the DB connection. Again, it is not working.
Associations and View Links missing in JDeveloper 11.1.1.3 and 11.1.1.4
I saw this under the "Messages - Log" tab in JDeveloper :
Aug 7, 2012 11:09:06 AM oracle.jdbc.driver
SEVERE: 3F794B56 Throwing SQLException: 3
Aug 7, 2012 11:09:06 AM oracle.jdbc.driver
SEVERE: 6C9DD8BE Throwing SQLException: ORA-00936: missing expression
I am using JDeveloper 11.1.1.6.
Any help would do, since I do not want to uninstall JDeveloper and reinstall it again and again...

Yes. In SQL Developer, when I click "Modify" on one of my tables, and then on "Foreign Keys", I can see them all.
Like I said, it worked on a different workstation, and it worked before on my computer.

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.

Can I create a foreign key when creating Business Components from Tables

Hi,
I would like to use ADF and JSF to create an application on our database. My problem is our database does not "conform". i.e. there are no foreign key constraints.
When I create a "Business Component from Tables" view, can I put in my own joins between tables so enabling the use of the generated views?
Jon L.

View object instances show up in the data control palette once you've added them to your application module's data model.
See these sections in the ADF Developer's Guide for more information:
Section 2.6.3, "Using View Objects in the Application Module's Data Model" talks about using view object instance in the data model as part of the overview chapter.
Section 4.5, "Understanding the Active Data Model" explains a little more about this
Section 5.3, "Using a View Object in an Application Module's Data Model" shows how to do this.
Chapter 10, "Overview of Application Module Data Binding" gives details on how the application and its view objects are exposed in the Data Control palette.
You can find the guide on the ADF Learning Center on OTN.

Business Components Programmatic Client Tutorial

Does anyone know why I get a :-
java.lang.NullPointerException
void bcbatch.Batch2.main(java.lang.String[])
Batch2.java:28
Exception in thread main
in the tutorial on the command >> Row[] customersFound = vo.findByKey(custKey,1);
The cust KEy contains the value 101
code as per tutorial
package bcbatch;
import oracle.jbo.*;
import oracle.jbo.client.*;
import oracle.jbo.domain.Number;
public class Batch2
public Batch2()
public static void main(String[] args)
ApplicationModule am_Ord = Configuration.createRootApplicationModule("OnlineOrders.OnlineOrdersModule", "OnlineOrdersModuleLocal", null);
ViewObject vo=am_Ord.findViewObject("CustomersView");
if (args.length==0) {
show("Customer ID is required.");
System.exit(0);
System.out.print(args[0]);
Key custKey = new Key(new Object[] {args[0]});
Row[] customersFound = vo.findByKey(custKey,1);
private static void show(String s) {
System.out.println(s);
} // end show()
}

Thanks,
I found the problem. The view is called CustomersView in the object navigator
but in the OnlineOrdersModule.xml the view is named CustomersView1 .You are providing the name for the ViewObject definition and not the usage/instance-name/member-name of ViewObject in an application module
Click on the application module node and in the structure pane you'd see a list of viewobject usages. CustomersView1 should be one of the ViewObject usages in the Structure Pane (as you have that name available as a member in the appmodule xml file).

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:

Reusing ADF Business components in a different installation

Hi,
I have a customer who's interested in creating Business Components, packing them in a jar file, send that file to another location where some developers want to develop JSF pages using those BCs. I know this is posible in 11g, but can that be done in JDeveloper 10g?

Hi,
yes and it is explained in the Developer Guide. In 10g you don't have ADF Library JAR files, but you can create JAR files from ADF BC to import in the new project

Nested Tables and Business Components

Hi,
We have developed a paradigm whereby all of our tables are of object types. In one example we haveL
create type addresslines_nt as table of varchar2(30);
We have another type:
create type address_ot as object(
lines addresslines_nt );
We create the TABLE off of address_ot with a nested table (store as) off LINES.
CREATE TABLE ADDRESS of ADDRESS_OT ....
In JDeveloper we want to create BUSINESS COMPONENTS and can not find a way for it (JDeveloper) to create a matching component for ADDRESS (the table) without it dropping a reference to the LINES property?
HELP!
Dave

BC4J version 3.2.x only supports VARRAY collection types.
BC4J 9i (which will come with JDeveloper 9i when it's release) supports both VARRAY and TABLE collection types.

Business components from multiple datasources

Hi All,
I want to create business components from multiple datasource. Please tell me if it is possible in ADF framework and Jdeveloper 11.1.1.4
I opened the Model.jpx and tried adding the two datasource but it is showing as a dropdown list from which I can choose only one.
My requirement is to have components from one datasource and read data from a second database to create a LOV
Please suggest how to go about it
Thanks

Hi,
There are many ways to achieve this.
If your requirement is just to read data from different database (and not to update it), then using a database link would be a better approach.
You could create a database link in the primary database (target database being the one you would like to query). Base your sql query for the vo using the db link.

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.
