Business Components from Tables

Hello to all.
I'm new on Oracle ADF.
I have a question: I create the objects froma DB by wizard Business Components from Tables.
Model: Project.xml
View: ProjectView.xml
Data Control: ProjectView
I created a jspx page, and I add ADF Table by data control.
Now I want to manage the current row seleted by java code. How can I do this? I haven't any java code for my models....
Thanks,
Cristian

Ok,
In a table a select a row after that I click on a edit button.
Now I have to take from the select row the field XML data (it's a XML DATA TYPE) parse it and add dinamically to the page ADF Components. The XML is like:
<root>
<template>
<inpuTextComponent title="Project title" creator="lucas" description="Some text"/>
<dateComponent title="Date" creator="lucas" description="Some text"/>
<fileComponent title="File of project" creator="lucas" description="Some text"/>
</template>
</root>
I've create the code for adding dinamically the components on page ( [on this thread|http://forums.oracle.com/forums/message.jspa?messageID=4085681#4085681] ) but I need to accesso to the selected row for read and also update the data.

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.

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:

ADF Business Components from Tables - adding more tables

Hi.
I have already created a ADF Business Components from Tables and added tables from the Oracle database.
My question is:
Is it possible to add more tables to the same Business Components model?
Not as a new Component Table, but with the same tables so i can use the same relations and mappings?

Hi and thanks! Yes, I am talking about recreating a the same View Object that i already has created. In my first model i had the tables Name and Address. I want to add a new table called zipcode to the same View som i can choose colums from the zipcode-table in the same View as Name and Address.
I'm not shure what you mean by Data Model tab? Can you spesify?
Thanks!

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.jdevx.ui.pkg.XPKComponentWizardEntityThread.createObjects(XPKComponentWizard.java:454)
     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.

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.
http://www.oracle.com/technology/products/adf/learnadf.html
Look for the ADF Developer's Guide for Forms/4GL Developers.

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.

What happened to annotations? building components from tables

File > New > Business Tier > ADF Business Components > Business Components from Tables]
there are no longer Entity Beans beign generated.. just useless views.
no java files to modify for complex foreign key relationships..
how to go about this?

Just like in 10g, you can use drag & drop. However, the data control palette was moved and is no longer a fully fledged independent palette, but rather a sub component of the Application navigator, check the data control accordion element of the Application navigator to see all your data controls, and view object. You can drag them in page or on task flow for actions.
As for session bean specifically, do you mean EJB session beans (that wouldn't make much sense since you're using BC4J) or JSF managed bean in session scope? if the latter, you can always evaluate the ValueExpression #{bindings} at any time in your code to get access to the current binding container.

Integrating ADF Business Components from heterogenous data sources

Hi all,
has anybody experience in integrating ADF Business Components from heterogenous data sources like ViewObjects from a DB2 database as LOV in a ViewObject from a Oracle 11g?
What is the best practice approach to integrate such different ADF Business Components in declarative and programmatic ways?
Thank you!

thank you for the answer! We already updated out BC according to http://www.oracle.com/technetwork/developer-tools/jdev/multidatabaseapp-085183.html
The DB2 ViewObjects are exported as ADF Libraries and imported in the BC of the project with Oracle DB ViewObjects. In the root AM I created instances from the imported DB2-ViewObjects as well as from the Oracle-ViewObjects, but when I start AM test environment it takes the preconfigured Data Source of the root AM. So I probably will pesneed to create two AMs for the different ViewObject types and for the two connection types. My question is what will be best practices to use data from the DB2-VO of AM_DB2 in the OracleDB-VOs as part of AM_Oracle? Should it be done only programmatically or can it be done also declaratively and any suggestions how to proceed?
Thank you!

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 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.

How to deploy Business components from DEV to QA and PROD

I developed Business components in my development database using JDEVELOPER and would like to port it to QA and then production. Because XML files have all your constraint names in there, which will be different in my QA and Prod., how do I make if work. Should I be playing with my XML files...???

The constraint names are not used at runtime, only at design time. They would be used if you decided to forward-generate the DDL for your tables.
Not to worry.

Business Graphics from Table and Series UI Element

Hallo experts,
i try to provide a business graph, but have some problems with functionality of Series UI Element as i suppose.
At design Time i don't know how many series i have, it's depend on data wich i get from table. So as i found for this i can use Series UI Element instead of SimpleSeries.
So i in Layout i have following structure:
Categorie
Series(List)->SeriesPoint->Numeric Value
In Context:
MainNode with following children:
                 Date attribute (String)
                 SeriesNode with following children:
                                    Name(String)
                                    PoinNode with attribute:
                                         (Integer) Summe
I set singelton of PointNode and SeriesNode to false;
Date Attribute is mapped to Catergorie
(Integer)Summe to Point Value
SeriesNode to to Series(List)
Here is part of code how i generate elements of some Node:
for(int m=0;m<allCodelineNames.size();m++){
String name=(String)allCodelineNames.get(m)

elem2.setChangelistSum(changeLists);
wdThis.wdGetChangeListController().wdGetContext().nodeSeriesPoint().addElement(elem2);
wdThis.wdGetChangeListController().wdGetContext().nodeSeries().addElement(elem);
The problem is so that i still don't see different series i see only the first one.
Also it's not clear how the mainNode knew which nodeSeries elemnts it had
i also tried to implement this way;
statElem.node().getChildNode("Series",i).addElement(elem);
where statElem is element of mainNode, but it makes no difference
Have you have any ideas, could it be that i make something generell wrong with this UI Element?
Thank you in advance!!

Hi Daria
Good news so far: layout structure is correct

However the context structure should be a little bit different (if I understand your structure correctly)

This is how it should be:
<ul>
<li>MainNode (for categories, singleton=true)</li>
<ul><li>Date attr (String)</li></ul>
<li>SeriesNode (for series, singleton=true)</li>
<ul>
<li>Name attr (String)</li>
<li>PointNode(for points, singleton=false)</li>
<ul><li>Summe attr (Integer)</li></ul>
</ul>
</ul>
Mapping should be done like this:
<ul>
<li>Date attr to Category->Description</li>
<li>SeriesNode to BusinessGraphic->seriesSource</li>
<li>PointNode to SeriesList->PointSource</li>
<li>PointNode to SeriesPoint->ValueSource</li>
<li>Summe attr to Values->Value</li>
</ul>
That's it for design time. As for code it should generate series like this:
        ISeriesNode nodeSeries = wdContext.nodeSeries();
     for(int j =0; j<seriesAmount; j++){
          ISeriesElement seriesElement = nodeSeries.createSeriesElement();
          nodeSeries.addElement(seriesElement);
          seriesElement.setName("Test "+j);
          IPoint2Node nodePoint2 = seriesElement.nodePoint2();
          for(int k=0; k<pointsAmount; k++){
               IPoint2Element point2Element = nodePoint2.createPoint2Element();
               nodePoint2.addElement(point2Element);
               if(k==4 && j==0)continue; // skip fifth element
               point2Element.setValue(""+(1+j*10 + k));
Set seriesAmount=allCodelineNames.size() and pointsAmount=amountOfCategories to get what you want.
I know that it's not very easy to understand but it works

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.
