Can i use Oracle 8i 8.1.5 for the deployment of Oracle Business
Components for Java or must i wait at 8.1.6 for support of EJB
1.1 (V I don't want use an application server such as OAS 4.0.8)

Oracle 8i's JServer will support Java 2 in the next release
8.1.6.

Is Oracle Business Components supported by IAS 10.1.3 ?

I have an application that uses JBO (also known as Oracle Business Components) for the persistance layer.
I am doing an evaluation of this technology and I want to find out if this will be supported by Oracle App Server 10.1.3 as well ?
thanks,
Amogh

No, I am not referring to the BC tester.
There is actually a UI available in 10.1.2 that I use for Oracle Business Components (JBO) that creates the XML and Java interface classes for the VO's and other aspects of the JBO framework automatically.
I was unable to find this UI in JDev 10.1.3. That was what I was referring to.
Has Oracle Business Component (JBO) now been renamed ADF Business Component ?
thanks,
Amogh

Oracle Business Component Browser won't connect to a SQL Server db

I have a System DSN called Northwind on my machine that uses a new login id called NorthwindUser and its password to access Northwind db on my sql server instance.
I am trying to use the Oracle Business Components Browser to test the data thru my application module but it wont connect. ( I have created a connection in JDeveloper 9.0.3 that uses JDBC-ODBC bridge and I can view all the tables just fine through this connection. )
When I right click on the app module and select test, it brings up a uid/pwd box in which i enter my credentials. Once I enter the credentials and hit enter it shows me the browser. There is no indication whether I was connected or not at this point. It shows me the view objects in the left pane but when i double click on one of the views it throws a JBO-25200 application module not connected to the database error.
I have trying various uid/pwd combinations incl. admin. I am running everything locally on a Windows Server 2003 build 3790 release and the sql server instance uses mixed mode auth. I am logged in as the Administrator on my box.
Any ideas?
Thank you in advance.

Business Components and OAS 4.0.8

I have several projects running in JDeveloper - one of them being a BC4J project, the others a mix of servlets and classes that make use of the BC4J project to interact with the database.
I have successfully managed to deploy the Business components application to OAS, but I get stuck after that.
How do I make use of this deployed BC4J application through a JServlet application?

Hi,
A colleague of mine mentioned that one may encounter problems deploying to OAS 4.0.8.
I understand that OAS 4.0.8.1 has major bug fixes and may make deployment substantially easier. Having not attempted either, I cannot verify his statement.
Hope you have success!

I have created an application using Oracle Business Components and Oracle InfoSwing controls.

Please let me know if its possible or not and any document detailing how to do it. To be more specific:
1) In the properties dialog for the Application Module, in the remote tab, there are options for Oracle8i EJB, CORBA and VISIBROKER, but nothing for OAS. So what to choose there?
2) If I run Deployment Wizard on the Business Components project with OAS option (selecting nothing in the Remote Tab), it fails (says nothing to parse in the source JAR file)
3) In the property pallette of the InfoProducer Session object, what to give in the remote proerties for OAS EJB.
4) It seems that no manual code change is required if they are deployed in Oracle8i or VisiBroker whether they are deployed in Local or EJB or CORBA(the deployment wizard takes care of it). Is it same for OAS EJB deployment also?
Please help. It's Very Very urgent.<HR></BLOCKQUOTE>

MapViewer: how to manage user selections in business components Java class

Hi list,
I'm a GIS developer with experience on Mapserver and Mapguide. Buit I'm totally new on Oracle Mapviewer and I'm doing a feasibility study on a project where I basically have a very simple GIS use case, but I don't know if it is possible to manage by use Oracle ADF Java API and Oracle Mapviewer.
I would like to use JDeveloper / ADF Business Components / ADF Faces.
This is the use case:
- Mapviewer should display a polygon layer from Oracle Spatial
- Mapviewer should display a polygon layer from WFS
- User should be able to select a polygon on Oracle Spatial layer and another polygon in WFS layer
- ADF Face map control should:
a) hilglight these two polygon
b) execute my buiseness component Java function passing the user selection (id?... coordinates?... or anything useful to get these two polygons in the business Java function) as parameter.
Is it possible?...
Any suggestions (or samples) for point b)?...
Thanks in advance for any help

Hi Arnd,
Thanks for answer.
Can you adreess me to some ADF project that include ADF Geographic Map control?
I've carefully studied what explained in manuls contained in JDeveloper Help. I've made something, but I have some issue I can't solve.
Here you are in details what I've made:
1) I've installed Mapviewer Quick Starter Kit
2) I've configured themes and base map by use on MapBuilder
3) I've built an ADF application with separated business and model-view-controller projects
4) I've created entities and views in ADF business project
5) I've created a JSF page in model-view-controller project
6) I've put inside page an ADF Geographic Map assigning my base map and his related toolbar.
Up to now it worked fine. My problems started at this point, on the attempt to add themes to be exposed to user interaction.
PROBLEM 1
I've seen that there are basically two options to add theme for user interaction:
a) add a predefined themes
b) add a color/point/graph bindable themes
Option b) seems not fit for my needs.
Color theme is only for regions and forces me to set a range of colors (I want to set exatctly two different color for two different table attribute value).
Lines seem not covered from any of them.
So the solution should be option a), predefined themes. But predefined theme seems not selectable and I don't know how to attach a selection listener.
Please note (about selection listener) that in JDeveloper Help, book "Web User Intercace Developer Guide", "Using ADF Geographic Component" there is a code sample, but the explaination on how to enter the backing bean method is truncated (it says "For example," and stop, nothing else).
My questions are: predefined theme can be selectable? And how can I attach the selection listener?.
PROBLEM 2
Up to now I've made no test on WFS themes, but of course, also these themes should be exposed to user interaction in the same way of predefined layers.
Is it possible?...
PROBLEM 3
Legends activated by ADF Map Toolbar seem not working for predefied themes, they display nothing.
Is it possible to fix or workaround in some way?...
PROBLEM 4
Are there any way to print maps?...
Best regards
Francesco

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.

How execute pl/sql command from Oracle ADF Business Components

can't find examples for how execute pl/sql command from Oracle ADF Business Components and how call pl/sql package procedure from ADF Business Components.
insert,update,delete rows in view object instance cache is good but if i must do some complex operations while insert,update,delete rows..it's more better for me to call
pl/sql procedure from oracle db.Am i wrong ????

Roman,
this should be similar to how it worked in JDeveloper 9.0.3. hava a look at <JDev903 Home>\BC4J\samples\StoredProc for a code example.

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.
To understand what BC4J give you read:

Resolving errors during Oracle 8i Corba Deployment for Business Components Project

Are these known errors, are they likely to cause problems? Was the deployment "successful"? The process did continue after summarizing the number of errors during the resolution process and eventually terminated.

Hi Peter,
The process of resolving the transitive closure of a large set of java classes (like the BC4J framework) can be quite memory intensive in JServer for the resolution phase.
You can alleviate this problem by turning the verifier (-noverify option) off.
That will speed up the resolution process a bit.
Also in your init.ora file check the java pool size and if it is less than 50 MB, do increase it to 50 MB or larger (The higher the better.)
Hope this helps,
-Kishore

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?

Oracle Objects / Domain / Business Components JSP App

Hi,
I use JDev 3.1 with Oracle 8.1.6
I would like to customize a Business Components JSP Application to be able to edit or add new row of a table containing one or more columns of type Object; like this :
create or replace type O_VALUE as OBJECT
TYPE_VALUE NUMBER,
STRING_VALUE VARCHAR2(30),
FLOAT_VALUE NUMBER(10,2),
BOOL_VALUE NUMBER(1),
INTEGER_VALUE NUMBER(10)
create table T_VALUE (
ID_VALUE VARCHAR2(20),
MIN_VALUE O_VALUE,
MAX_VALUE O_VALUE
I have created a domain for the type O_VALUE to incorporate in the entity created for T_VALEU by the wizard.
Is there a Wizard for editing an attribute of type Object of an entity ? If not how programmaticaly do that ?
Thanks a lot...

You can use the DataTags to display/edit objects types. In our next release we will update the DataWebBeans to support this.

Oracle ADF Business Components Vs PL/SQL Application

Hi,
Has anybody used Oracle Application Development Framework's Business Components (ADF BC)? What are the disadvantages and issues that you faced? Can anyone compare PL/SQL with ADF BC?
Would like to know the advantages and dis-advantages of both the technologies(PL/SQL and ADF BC).
Can anybody help on this?

Hi,
Not sure what exactly you are looking for.
But let me explain so that you can get some idea of their working and ofcourse difference.
ADF BC which are nothing but the Entity Objects (EO) and View Objects (VO) which are the Java representation of the DB.
EO is like database table and is a 1-o-1 representation of the underline database table as a Java class file.
VO is like database view and is always based upon some custom SQL or combination of one or more EOs.
For developing a Database based application you always layer where you can handle the database objects and can also write the business logic or validation for the
data entered at the UI.
PLSQL is straight forward is the language to write business logic at the database level.
I hope this will give you some details.
Thanks,
KKCHOPRA

Business components based on Oracle views

I am trying to create business component objects in a master-detail relationship based on Oracle views rather than on the underlying tables. The wizard does not create associations or links since the views have no foreign keys. I created the associations and links myself, but I am unable to add them to the data model. I am using the beta v5.0, but I had the same problem in v3.23. Can anyone help?
Thanx in advance

Here are the steps I just tried with JDevi 9i Beta:
[list]
[*]SQLPLUS SCOTT/TIGER
[*]CREATE VIEW DEPT_VIEW AS SELECT * FROM DEPT;
[*]CREATE VIEW EMP_VIEW AS SELECT * FROM EMP
[*]On my workspace: Right-mouse / New / Empty Project
[*]On my new project: Right-mouse / New Business Components...
[*]Next, to the connection panel
[*]Set the connection, and next
[*]Pick a package name and next
[*]Tick the [x] Views checkbox, and select EMP_VIEW and DEPT_VIEW
[*]Uncheck the "View Objects and View Links" box, since we don't want these created automatically.
[*]Click (Finish)
[*]In navigator, select my "DeptView" entity and edit it (the view is called "DeptViewView").
[*]Click on the "Attributes" tab
[*]Select "Rowid" in the attribute list
[*]Click the (Remove) button
[*]Select the "Attribute Settings" tab, and select the "Deptno" attribute.
[*]Check the [x] Primary Key checkbox for "Deptno"
[*]Click (Ok).
[*]Repeat steps above on "EmpView" entity to remove Rowid attribute and make "Empno" attribute the primary key. (NOTE: Since views don't have constraints, we couldn't detect the primary key constraint, so we default the ROWID to be the primary key in the wizard).
[*]In navigator, select my "DeptView" entity, and right-mouse / New Association...
[*]Using the wizard I create a association based on the "Deptno" attribute, and with a 1 to many cardinality.
[*]I right-mouse on "DeptView" entity and select New Default View Object... to create the "DeptViewView" view object.
[*]I right-mouse on "EmpView" entity and select New Default View Object... to create the "EmpViewView" view object.
[*]I right-mouse on the DeptViewView view object and select New View Link...
[*]I create a new view link between DeptViewView and EmpViewView
[*]On the "Source Attributes" panel, I select the "Dept2Emp" association I created above, and click the ">" to shuttle it to the selected list.
[*]Click next and notice that by selecting the association, it automatically picked the right attributes for both sides for the view link automatically.
[*]click next, then (Finish)
[*]I right-mouse on my package and select New Application Module...
[*]On the datamodel panel, I see a tree view of "Available View Objects like this:
+ Project 3
|
+---[-] Package3
|
+---[SQL] DeptViewView
| |
| +--[SQL] EmpViewView via MyViewLink
|
+---[SQL] EmpViewView[*]I select DeptViewView in the available list and click ">" to shuttle it to the selected list in my data model
[*]In the SELECTED list, I select the DeptViewView that I just added, to make it the current view in the selected list.
[*]Back in the available list, I select the "EmpViewView via MyViewLink" and shuttled it to the selected list as a detail of the current view in the selected list.
[*]I click finish
[*]I right-mouse on my AppModule and select "Test..." to build and test my appmodule.
[*]I click (Connect) on the tester start page
[*]In the tester, I right mouse on "MyViewLink" and select "Show".

After these steps, I see data correctly.
