"Importing Business Components" Question

I see no way of updating Imported Project paths through jdeveloper. For example updating the current project which imported common-bc4j-code-2.0.0.jar to common-bc4j-code-3.0.0.jar. The only way we were able to do it is by going behind the scenes and updating the jpr and jpx files. Am I missing something? It would be nice if there were a screen that showed all "Imported Business Components" which gave the ability to modify the path.
Another problem our team has ran into is the way classpath and libraries are stored in the metadata file. It would be nice if you could define "classpath variables" in jdeveloper so that all developers on the team could create a variable say "EXTERNAL_JAR" and they could have that path point to whatever file directory on there operating system they chose. Maybe jdeveloper has another way to manage this?
Thanks,

JDev 10.1.3.3 - issues with imported Business Components

Hi,
I have got some issues with importing Business Components in JDev 10.1.3.3.
I cannot discover/use the imported components.
What I did is the folowing:
1. In a existing project I extended the default base-classes to create our own layer
2. created a project called ModelShared
2a. configured the project to use the base-classes I created in step 1
2b. created an entitybased-viewobject (RefCodesByDomain)
2c. created bc deployment-descriptors
3. created a project called RelatieModel in the same workspace as ModelShared
3a. added dependencies to the deployment-descriptors as well as the project created in step 2
3b. configured the project to use the base-classes I created in step 1
3c. imported business components
Although I did not recieve any errors during the import of business components, I am unable to add the vo (RefCodesByDomain) to a service.
I do see the package which contains the vo but is has no entries.
Importing the business components to a new BC Project in a seperate workspace did succeed (I could reuse the vo).
I tested a little further and the folowing occurred:
4. I created a new vo in the ModelShared Project
5. I deployed the ModelShared
6. Restarted JDeveloper
7. Got the folowing error message in the console window when expanding a service in my datacontrol pallette:

8. In my other "fresh" bc project I was able to use the newly created vo.
9. When I added a VO to my shared project, all projects that are refering to the shared project loose their vo's in the data-controlpannel
Do you have any suggestions?

JDev10.1.2: Importing business components problem

Hi guys, I hope someone could help me here:
I have a business components project; from it I created a business components archive (deployment profile), and this profile generates two jar files. One jar file contains the business components and the other one just contains the application modules' interfaces.
Then I imported the business components into another model project (in another workspace) from the jar files using File / Import / Business Components and selecting the package's xml file.
Then I have a third View project which will have bindings to the last model project. The problem is that in the Data Control Palette the application modules appear with no interface methods (just Commit and Rollback).
What should I do to make the View project's Data Control Palette aware of the application modules' interface methods so I can bind them to Data Actions?
Thanks very much!

Unable to import package. This file is not a Business Components XML file

Hi,
I am using Jdeveloper 9.0.3(Build 1325) and trying to extend a VO. Project > Import Business Components and select the VO, AM or EO xml because Sourcing Negotiation creation does not have a server.xml and I am getting the following message "Unable to import package. This file is not a Business Components XML file.". Should I make something else to enable extension?? Does a patch required to make extensions. Any help would be appreciated.

What I know is that server.xml is not a must. This is the easiest way to import appropriate xml files. My question is, when I am trying to Project>Import Business Components > xxxVO.xml I am getting the above error although the xxxVO.xml is a Business Component. I wanna know that should some patch be applied to Jdeveloper (Build 1325)?? (by the way at first I tried with Build 1312 and the same error raised)

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")

Business Components Import problem

Hi,
I am having trouble using the Imports option in the Project Properties of my Model project (Project Properties -> Business Components -> Imports). I have a jar that I want to import to the project. However, when I click the Import button, locate my file and click Open, nothing happens. It doesn't import the jar, nor does it close the Import File dialog.
Is this a bug? I am able to get around it for now by modifying the Model.jpr and Model.jpx files but this isn't a long term solution.
Thanks,
Tracy

If you are attempting to import ADF BC objects packaged in a jar/adflib this is a known issue in the preview that has been resolved in more recent builds.

We have not been able to reproduce the exact same error, there would be a problem if we were trying to write to the library file, as those objects are read only, of course. Can you tell me, the entity object that you are referencing, has it ever appeared on a diagram? An easy way to tell, if you don't know is by looking at its XML file and see if it has an ID=some long string entry.

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?

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!

Business Components for Java & XML

In the application I am currently developing, I am using XML metadata to communicate between a web browser and servlets (the xml is parsed by a servlet using an XSL stylesheet to output plain html). To build the XML, I am using the XML SQL utility and the following code:
try{
dset = new OracleXMLDataSetExtJdbc(conn, (Reader)sqlStr);
dset.refreshDataSet();
}catch (Exception ex){}
OracleXMLDocGen doc = (OracleXMLDocGen) new OracleXMLDocGenString();
OracleXMLQuery qry = new OracleXMLQuery(dset);
qry.setRaiseException(true);
qry.getXML(doc, qry.DTD);
My question involves Oracle's Business components for Java. We have recently been doing more research into this technology and the features of it are quite appealing. However, as far as I can tell, there is no way to use the Oracle XML Utilities in conjunction with the BC4J. ie. XML is created based on a view object, not a SQL query to the Database.
Does anyone know of any way of acheiving this XML generation based on a BC4J foundation?

A BC4J View Object is effectively a Java component that represents a database query.
The key difference is that the view object exposes a rowset API to work with which is
fully updateable, fully scrollable, and automatically coordinated with underlying business logic which you have encapsulated into your companion entity objects (another BC4J Framework building-block component). View objects can also be used to create any interesting hierarchy of master/detail/detail queried database information using "View Links" to link the View Objects together. This allows you to effectively work with a "tree" of data that is perfectly shaped and filtered to the needs of the task at hand -- including self-referential "parts-explosion" kind of view links.
In JDeveloper 3.1, BC4J ships with a utility class called oracle.jbo.xml.XmlRowSetRenderer which automatically supports rendering the results
of any view object (and its "tree" of view-linked view objects) as XML, either in DOM format or into a Writer.
In JDeveloper 3.2 (the next major release) the B2B XML features of the BC4J framework are further enhanced by supporting true, bidirectional XML-in and XML-out for any view object. This means that an XML message can be "fed" to any view object and it natively knows how to handle inserts, update, deletes and (most importantly) enforcement off all shared business logic from the underlying, related entity objects.

How do we use our .jar file of Re-Usable Business Components in 11g?

Hi All:
We have developed a library of re-usable Business Components in 10g utilizing the instructions found here:
http://download-west.oracle.com/docs/cd/B31017_01/web.1013/b25947/bcadvgen007.htm
We are now planning on migrating to 11g, so we need to know how to implement this re-usable business component library.
Is it possible to use it as it stands created in 10.1.3.3?
Or do we have to migrate it over? And how is this done since we still have applications that use it in 10g?
Your input is very appreciated since this is an important step in our migration plan. Doing this correctly is crucial to our shop. We have been trying a few things, so far with no luck.
Thanks very muich.

Shay:
My colleague that received the errors is going to unexpectedly be off for a few days, so I tried to re-create the errors so that I could get back to you. What was essentially happening was that on certain tables, the first column was missing from the EntityImpl. These tables MIGHT be those that had a primary key that when JDev removed the underscore, had the same name as the Oracle table. For example the table name was ResidenceCode and the primary key of that table was Resident_Code and was found as the first column in the table. HOWEVER, when I tried migrating our reusable business components libarary .jar file, using 11.1.1.2.0, I did not experience the same errors, so I'll get back to you. She was perhaps using an older version of 11g?
But I do have one question. Can we use a .jar file of reusable business components built in 10g in 11g? As you can imagine, this library is being used in other applications, and we'd like to prevent having two copies, if at all possible. Because of all the structural changes, I am guessing we can't, but I'd really appreciate your reply.
I have found the documentation *36.7 Working with Libraries of Reusable Business Components* at http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974/bcadvgen.htm#CHEFECGD with respect to 11g. If you know of any other 11g considerations with respect to this task, that would be great as well.
Thanks Shay, I really appreciate hearing from you.

How to use an existing data model using Business Components in OEPE

I am a beginner in ADF. I am working on a project with an existing data model that uses Business Components (EO, VO and AM). I know that OEPE does not handle the creation of BC, so if I want to modify them, I will have to do that in JDev. That's fine.
OEPE can create pages with drag and drop like in JDev. In my eclipse ADF projects, I would like to use the existing BC, to be able to use the bindings with ADF Faces. So far I have nothing in the Data Controls tab.
How to import the BC into the Data Controls tab?
JDev 11.1.1.6
WLS 10.3.6
Eclipse Kepler

We currently don't support DataControls based on the ADF BC technology. We will consider such support if there is a strong interest in that use case.
Independent of the IDE's you use, there are ways to expose services based on ADF BC that can then be consumed by the view layer. A Google search will point you to some of the approaches.
HTH. Thanks for your interest in OEPE.

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.
