Business Components Performance

We have big client server app that we are planning to migrate to Business Components and Java App. Has anybody suffered performance problems? Is it ok to migrate?

Type of Deployment? Fat Client? ( Java running in JVM on desktop with Swing? )
Startup times can be a bear. Particularly if you have lots of tables and lookup tables. Uh...persistent entity objects.
My current startup runs from 22 seconds ( NT/128MB/PIII-500) to 210 seconds ( W98/32MB/PI-133)... Depending upon app size, recommended a minimum of 64MB real memory committed to the application. As usual, your mileage will vary.
Once it gets running I've not seen performance problems, but your mileage will vary according to:
1. How good the SQL is
2. How well the database is tuned
3. Hardware on client
4. Hardware on server
5. Whether you do everything on the client, or have extensive stored functions and procedures to perform business tasks
grin Frankly, since we're replacing a custom legacy application, the resulting executable leaves the old app in the dust ( despite Java, bc4j, jdbc and all )
I am also starting to investing JAR optimizers and native EXE converters. Again, if anyone is further along than me on this I'd appreciate any input.

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.

Business Components for Java - Pooling

I need a little bit of clarification regarding business components for java...
I would like to create a jdbc connection pool for my application to avoid the overhead of creating new jdbc connections each time a client connects.
Since I'm using BC4J, and the jdbc connect is contained within the bc4j components, I connect to the database using:
session.getTransaction().connect("jdbc:oracle:thin:test/test@ccmain:1521:clincare");
Does the BC4J architecture do any connection pooling itself? My plan was to create a pool of ApplicationModules that could be easily and quickly accessed, but if bc4j already pools the jdbc connections internally, then I'm not sure I would gain any performance with my ApplicationModule pool.
Any input would be appreciated! Thanks!

<BLOCKQUOTE>quote:<HR>Originally posted by Steve Muench ([email protected]):
[b]Does the BC4J architecture do any connection pooling itself?
Strictly speaking, in JDev/BC4J 3.1, the answer is no. BC4J 3.1 offer Application Module pooling and since AM's are paired one to one with connections, using a pool of AM's is pretty much the same as using a pool of connections.
However, in JDev 3.2 we've dramatically improved the features for use in a high-throughput Web application scenario and in doing so have implemented a more flexible application module pooling mechanism as well as a connection pooling mechanism that work together to allow developers to exploit application module instances to retain pending state without "pinning" that pending state to a particular AM instance and without "pinning" a dedicated database connection.
Early customer previews we've done on our 3.2 features have been receving rave reviews, so we'll excited to get it out to a wider audience this Fall.
For now, you're best bet is to exploit the application module pooling mechanism.<HR></BLOCKQUOTE>
Is JDev 3.2 going to include a support for registering application module not from the property file, but using specific database username and password for the underlying connection ?

Can not see the menu of New Business Components Package in jdeveloper

I am just follow the developer guide.
and when I create the Business Components Package, the guide said that
========================================
In the JDeveloper Navigator, select the OA Project where you want to create your package.
From the main menu, choose File > New to open the New Object Gallery.
In the Categories tree, expand the Business Tier node, and select Business Components (BC4J).
In the Items list, select Business Components Package to open the Business Components Package Wizard. You can also right-click on the OA Project and select New Business Components Package to navigate directly to the Business Components Package Wizard.
=====================================
In fact I can not see the menu about Business Components (BC4J) in the File/new/buisness tier/Business Components (BC4J).
I can only see the File/new/buisness tier/ADF Business Components.
And can not find the "Business Components Package" under ADF Business Components either.
I am using the JDev Extension for OA (p5856648_R12_GENERIC.zip) and EBS 12.0.0.
And I create an OA Workspace and OA Project.
can anyone help?

Problem to deploy to a WebService interface for ADF Business Components to Weblogic Server

Hi,
I'm trying to deploy a custom application ,in which i have exposed ADF Business Components through a WebService interface, to a standalone weblogic server.
Application Module is configured with a Service Interface for ordinary ViewObjects.
Now I want to create a EAR file of this application to deploy it on the weblogic server.
But I got an error while deploying it.The error i am getting is shown below.
ERROR: No Java EE modules detected in EAR archive. Deployment aborted. == (oracle.jdevimpl.deploy.ear.WeblogicAssembler)
I have followed the steps mention in the below link :

Please suggest what i could be doing wrong.

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.

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.

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.

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:

How to load data from XML DOM into tables using Business Components


Hi,


I need to upload XML file (it's not a problem) an load data (DOM tree) from this file into relationan tables. This filelooks like this:


<Departments>
 <Department>
 <DepartmentName>OPERATIONS</DepartmentName>
 <Localization>BOSTON</Localization>
 <Employees>
 <Employee>
 <LastName>TURNER</LastName>
 <Job>SALESMAN</Job>
 <Manager>7698</Manager>
 <HireDate>1981-09-08</HireDate>
 <Salary>1500</Salary>
 <Commerce>0</Commerce>
 </Employee>
 </Employees>
 </Department>
</Departments>


Is there any Business Components support to obtain this ? What about primary and foreign keys values (there is no in XML file). How to place this XML data in appropriate tables ?


Kuba


Pl post details of exact OS and database versions, along with a sample of the XML file and description of the tables. What have you tried so far ?

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.

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?

Connecting to a database from Business Components JSP Application

Hallo All!
Can anybody give me an advice about connecting to a database from Business Components JSP Application? In all examples I see that Oracle user name and password placed in configuration file.
How can user provide his own name and password to start Oracle session and how then hi can close this session?

Dear Laura,
I mean first variant where the database would be the same:
scott/tiger@database1
foo/bar@database1
Of course I understand that we must register every user in database by "CREATE USER XXX" and it is unacceptable for Internet. But it may be very convenient for an Intranet because we can build access restriction based on set of views without any changes in applications.
Best wishes,

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.

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.
