JUnit with Business Components

I'm trying to test how JUnit works with a business component project. I installed JUnit extension for JDeveloper 9.0.3.5 with OA Framework (for 11.5.10 CU2) and followed the associated help files to create a test suite for the Tutorial project and the CreateAM application module. Part of the setup is to create a Configuration file for the application module, which I did by right clicking on the AM and selectin Configuration and New.
When I run the test suite, all the tests error saying that it couldn't find the Configuration that I created for the application module. Has anyone run into this and know what the resolution is?
Thanks, Rob

Thanks for that link, it provides alot more detailed information on what is going on than the basic help pages provide.
I still have the problem though. In step 3 of that guide it says to select a Configuration. You create that by right clicking on an AM and selecting Configurations and New. When you click OK with the 9.0.3.5 build 1437 (JDeveloper with OA Extension for 11.5.10 CU2), the bc4j.xcfg doesn't get updated and when the JUnit test is run, it errors saying it can't find the Configuration. I tried creating one manually from an example Configuration I created using JDeveloper 10.1.2 (it works in that version) but the tags must be different because then JUnit gives a parsing error.
I opened a SR with Oracle to see if they can reproduce the test case.
Thanks, Rob

Jersey implemtation with Business Components

Hi,
I would like to implement a REST interface based on jersey for my adf application.
I my resource classes I want to return the data from my view objects.
What would be the 'best practice' for creating the application module inside the jersey resource class?
For example I have an App Module 'MainAppModule' with the view object CountriesView. (Based on the HR schema)
This is the Java class with the jersey annotations:
package be.glnd.view.jaxrs.resource;
import javax.ws.rs.GET;
import javax.ws.rs.Path;
@Path("countries")
public class CountriesResource {
@GET
public String getCountries() {
//instanciate App module en query view object?
PS: No authentication, empty project just for rest interface.
Thanks,
Gert

Business Components not available while using Model Configurator in ID

Hi,
In ESR:
I created a ProcessIntegrationScenario PIS_myScenario (and completed with sender and receiver components, actions etc)
In ID:
I created and activated two BusinessComponents: BC_A and BC_B
I created a new Configuration Scenario: CS_Test, and selected Type of ES Repository Model:"Process Integration Scenario".
and launched "Model Configurator".
Now in the step "Assign Components" i see a tab "Assign Business System Components for A2A Configuration" , in that for "Communication Component" value, when i tried to select from the value list, it is only showing the Business Systems and not the Business Components BC_A and BC_B.
By using the "Model Configurator" how can we create scenarios using the "Business Components" instead of "Business Systems".
as i am trying the test scenarios, i want to use Business Components, i.e business services in earlier versions.
I also opened the Business Components BC_A and BC_B and added the corresponding inbound and outbound service interfaces in the receiver and sender tabs.
after that also, the Business Components are not visible for selecting from within Model configurator.
let us know if its possible

thanks abhishek for your reply.
as mentioned in the reference link given by you, i edited the Process Integration Scenario in ESR, i ticked the checkbox "External Party with B2B Communication", and activated.
In ID, in Model configurator, i can now see and select the Business Components BS_A and BS_B.
but when i try to generate the configuration objects, it says: Not Configurable: Component view only contains external application components.
so cannot proceed with Model configurator with Business components, in my scenario.
seems i need to use only Business Systems.

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.

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.

BUG: Business Components using Datasources on Websphere - statement closed

Hi,
This is an unusual combinatation, we are deploying business components projects on websphere with a SQL Server database. This was originally deployed all to Oracle. We have managed to convert the project sucessfully (JDeveloper 10.1.3) and on Websphere, however when we moved our application module configurations (bc4j.xcfg) to use JNDI data sources which works in Jdeveloper, we are encountering problems using websphere with business components and datasources.
The statement closed error occurs when trying to calling executequery() method on the view object, not the first time the JSP page is accessed, but the second time. Refresh page all is good. Access page again error occurs. Very consistent.
Our code will often do applicationmodule.findViewObject("name"), if not found then create it, otherwise use the vo and kapow bombs out on the executequery method if reusing the view object.
ERROR
DSRA9110E: Statement is closed.oracle.jbo.SQLStmtException: JBO-27122: SQL error during statement preparation.

Ampooling is on. It appears the jdbc prepared statement is being closed but bc4j is expecting to still be open?
Any ideas on diagnosing the issue or app module config changes greatly appreciated.

Hi Steve,
This is not a composition association. Actually, this is an association from a table to an intersection (many-to-many) table. The code in my service is based on the SRDemo, see SRServiceImpl#updateSkillsForCurrentStaff(List) and is called on a save button from a shuttle page.
The current master is the master I want it to belong to. The link to the master gets correctly saved in the database (just as in the SRDemo). We can also navigate from the master view row to the find the detail view row using the generated RowIterator. However, this does not work from the master entity row to the detail entity row. The problem is really at the entity level.
Thanx
Olivier

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:

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?
Regards,
Romano

Hi,
since this appears to be a WebCenter related issue, I suggest to try the Webcenter forum WebCenter Portal or to log a bug

Also, report the problem on the JDeveloper forum on otn.oracle.com, or contact Oracle support, giving the information from this message.

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.

The major difference between Oracle BC4J with WebSphere Business Components

Hi BC4J/ADF experties:
who could help to explian the difference betweenn IBM WebSphere Business Components(San Francisco) with Oracle BC4J(ADF) ? , the both product to emphasize Component-based developemnt but WebSphere Business Components have been define some enterprise base component that can provide extend and customize. how do you look up on this product strategy for developer ?

I guess one difference is who can use it, for IBM components:
Available for ISVs and Technology Partners only, and requires that the ISVs and Technology Partners have either a SanFrancisco Technology License Agreement, SanFrancisco Version 2 Development License or a SanFrancisco Version 2.1 OEM agreement and an appropriate transaction document executed under the respective base agreement.
BC4J is for use by anybody who uses JDeveloper.
IBM's solution seems to lock you into using Webssphere, with BC4J you can use whichever application server you want.
I guess the problem is to find someone "who could help to explian IBM WebSphere Business Components" - I can't seem to find a good expenation of what it does, but it seems to be a set of functional components that do specific tasks.
This is not what BC4J is about.
IBM's solution forces you to use EJB. BC4J gives you a choice of deployment options.

New Business Components doesn't load with their foreign keys

Hi,
When your database schema has already been defined and nothing moves, the creation of Business Components in JDeveloper works pretty well.
When you are developing a real application and sometimes the customer changes his mind or something, you have to add some Business Components later in the process.
My question, why associations and links doesn't follow the creation of new business object?
Example 1
I load every database object I need. All associations and links are created.
Example 2
I have let say three tables. I create my new Business Components by selecting only 2 tables out of 3. If there are foreign keys, they are loaded.
Now, I want to create the last business components (table 3 of 3), and this table got foreign keys pointing to one of the two previous tables I just loaded.
Surprise, it won't load any foreign key.
I have tried multiples ways to synchronise object, I don't see it working. So I have to create every associations and links myself. Anybody knows a trick that they want to share for this kind of situation?
Thanks

Hi,
actuallly Chris Muir brought up the idea to make the entity wizard more intelligent of this. However, this is currently a suggestion by him and we work with the developers to get this idea validated and eventually in the product. Since then you will have to create relations manually. Note however that in this ADF BC behaves like the EJB entities from table wizard that also can only look up dependencies if the table is part of the selection. In your case, you select a single table and the table has a FK to another table. However, the other table is not part of the selection so why would ADF BC want to create the key relation ship. Before you say, it could parse your project, let me add that related objects may be saved in ADF libraries, which means we would parse the class path, which may be a long time waiting for you for the IDE to get back to you. So this requzrement - though valid - needs a different approach in the wizards. Until then you will have to build it manually.

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.
