Generate BC4J components from Designer

Oracle Designer 9.0.2.80.1 vers: 4.0.12
Oracle SCM RON: 9.0.2.80.1 vers: 4.0.12
Oracle Jdeveloper 9.0.4.0 (Build 1419)
I try to generate BC4J components from Designer definitions from SCM.
In Designer:
I make workarea (WA27) as rep_owner
and child application (AP27) below WA.
I create one table (TABLE1) and one (Java) module to that simple table (TABLE1).
I check in and out application table and module.
In JDeveloper:
I make connection to SCM Database as user rep_owner
Test succeed and I see below Connection1Functions tables , procedures .. of the repository.
I do not see among tables just created table (TABLE1).
I make workarea an project below that WA.
Then I right-click on new project and choose Business Tier/Designer Generation +
Designer BC4J and click OK
Designer BC4J Generator Wizard starts
Wiard continues and I choose to workarea: WA27 and next
In next phase wizard shows only workarea WA27 not application below that.
I designer too old or do I need changes to definitions of the repository.

Language of the module have to be Oracle Forms (not JAVA).
After change wizard will find that container (= application) AP27 and modude(s) below that. OK!!!!
Fine !

Generate SQL scripts from Designer 6

Hi all,
Does anyone know how to generate an SQL-script from Designer? I want to maintain the code in the repository, and also document usages against the script. I've found ways to document the script, but then I can't generate it....
Thanks in advance,
Ronald

Ronald,
How did you record the SQL script in designer? As undefined pl/sql module (type= "null")?
If so, you cannot generate the script with the ddl generator. To do so you could change the type to procedure and make post-generation changes to the script (cut of f the procedure header and trailer lines). An other way to generate it is to write your own SQL script generator as a headstart utility. You might take a look at the html help file generator utility which does a similar job (create a o/s file based on the repository contents).
Let us know if you succeed.

The CG$ASK_COMMIT alert is being generated from designer but from where??

I am generating oracle forms from designer and the generated form contains an ALERT called CG$ASK_COMMIT. My question is, which generator property, specifies this ALERT?? I have looked everywhere? I am trying to change the alert type, style, wording without modifying the form after generation.
Any help would be great.
Thanks in advance,
Terry

I don't know if there is preference for it. What we do is put this in the when-new-form-instance:
     l_alert_id := FIND_ALERT('CG$ASK_COMMIT');
     IF NOT ID_NULL(l_alert_id) THEN
        SET_ALERT_PROPERTY(l_alert_id,ALERT_MESSAGE_TEXT,'<your message>');
        SET_ALERT_BUTTON_PROPERTY(l_alert_id, ALERT_BUTTON1, LABEL, '<your label>');
        SET_ALERT_BUTTON_PROPERTY(l_alert_id, ALERT_BUTTON2, LABEL, '<your label>');
        SET_ALERT_BUTTON_PROPERTY(l_alert_id, ALERT_BUTTON3, LABEL, '<your label>');
     END IF;

Cfg61.dll - Cannot generate forms from Designer

Hi
When I try and generate a form from Designer 6i (i am using the tutorial app) i get the following error message :- CDD-23564 : The file "g:\orant\BIN\cfg61.dll" could not be loaded or does not exist. However the file does exist in the specified location. Ive looked thru the on-line documentation and checked the registry but cant see anything obvious. Ive got the following configuration on my machine :-
Windows NT 4 (service pack 3)
Oracle 8i (version 8.1.6)
Designer 6i (version 6.5.28.8.0)
Any advice would be welcome.
Thanks

The configuration looks ok except for Th eService Pack. Designer requires Service Pack 5 or 6 or Wondows 2000 Service Pack 1. Try changing the Service Pack.
All the best

Export from Designer to Erwin. Is it possible?

Hi all,
I need to create a Data Model and send to my customer in a Erwin format (ER1), but I don't have a Erwin licence.
Can I create this data model in a Oracle Designer, and export to a Erwin format?
Tx,
Everson

Hi Emerson,
I understand - I think it comes down what the requirement is and how much you're willing to spend!
Is the model you're creating a Logical or Physical Data Model (or both)?
If it's Logical, and you want to be able to view it in Erwin, you'll need to use a third-party product to convert it from Designer to Erwin (hence link to http://www.metaintegration.net/). I don't think this will be cheap :-(
If it's a just Physical Data Model, i.e. tables, FKs, etc, you can generate the DDL from Designer and this can be reverse-engineered into Erwin. I assume it will look the same as it did in Designer on the basis the tables will not have changed. If your Logical and Physical Model in Designer are very similar, i.e. entities map directly to tables 1:1, you could argue that what you reverse-engineer into Erwin closely resembles a Designer Logical Model.
Hope that helps.

Business Components from Any Device

Articles and sample code show how to use Oracle XSQL Servlet to access BC4J components from XML documents. Query the database and manipulate data from any Web-enabled device.
http://otn.oracle.com/sample_code/products/jdev/htdocs/x2vo/x2vohome.html
Regards,

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.

Generating BC4J from 9i Designer

I am impressed that Designer9i can generate BC4J Form integrated with JDeveloper after seeing the Designer 10g Online Viewlet Demo
http://www.oracle.com/technology/products/designer/demos.htm
Designer 10g can generate BC4J Forms in JDeveloper. I try to test it using Develeoper Suite 9i (Designer 9.0.2.4 and Oracle9i JDeveloper 9.0.2.829).
I follow the steps but I cannot find Business Tier>Designer Generator from within JDeveloper.
Does any one know whether Developer Suite 9i can support BC4J Form Generation in JDeveloper 9i? or these features are only available in Developer Suite 10g?

Hi,
This facility was only available in JDeveloper 9.0.4 onwards.
Thanks,

Why not generating adf bc projects and components from offline database

I imported offline database objects from my production database that is big. I would like designing some business components without necessarily the database running and be connected.
Is it a reason why an adf bc project may necessarily connect to an on line database ?
Why it is not possible to generate adf bc components from off line database objects ?

The ADF BC design time has always required a database connection, to be able to test the validity of expert-mode SQL statement for one reason, but not the only one. We have not lifted that requirement in the 11g release.
I filed ER# 6056701 to track your request. Thanks.

ERROR WHEN USING JHEADSTART TO GENERATE ADF BUSINESS COMPONENT FROM DESIGNE

Use JDeveloper to generate a ADF Businness component using Jheadstart from

Yes, this is a known issue. We will fix this for the next release.
Having said that, the next release will contain the JHeadstart Forms2ADF generator which directly reads Oracle Forms .fmb files to ADF, without the need to use Oracle Designer, avoiding problems like this alltogether.

Urgent: Forms generated from Designer not loading on 9iAS

HI,
I have generated a form using designer 2000, when I try to run
the form on the web it says that the ofgcall library is missing,
though the form runs when executed from the form builder.
other question is.
when I copy the .fmb file to any other destination, and try to
run, it refuses to create the .fmx of the file saying cannot
create the .fmx ( error: frm-30087 ) , I checked the error but
unable to find the described error, as I am logged into the
system and Administrator and the directory in which I m working
is fully accesible and there is sufficient space.
any please help.
Sreekant

Even I faced the same problem. This code works on Windows 95 but gives error "User Defined Exception" when running the same form on Windows NT. May be the API function behined this function call is a primitive one.

Generating forms from Designer... bug?

Sorry for offtopic....
I'm trying to generate form from designer. The form has 1 data module with base table & one lookup table usages. One field from lookup table is displayable. When I set "Display type" property of this field "Text" disigner says: "CDI-21600: A running utility.. etc." BUT when I set "Display type" property of this field "PopList" - everything goes well! I don`t even need to restart designer. This is .log from designer

The CDI-21600 error message means that the generator is hitting an unhandled

masks the underlying exception error. To see the real error do the following:
1. Go into the Registry Editor (REGEDIT).

Hi,
Of what i gather from ur scenario...this is what i did in one of my reports.
I had to use two subreports and they had to occupy one cell each, in line with other fields.
To obtain that,all the fields required in the subreport i put them into a text box.Therein restricting the fields to the txt box only...
Then import that sub-report as it is.
It worked for me....
try out...
All this only if've understood u right...

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.

JClass components from KLGroup

Does it make sense to integrate these classes framerwork in a JDevelopper 3.1 project ?
Is it a complementary or a concurrent framework ?
KL propose JClass SwingSuite and JClass Field. Is it possible to easily integrate (link with) these classes with business components generate by JDeveloper 3.1 ?
Do you know project with both JDeveloper 3.1 and KL Classes ?
KL offer integration for JBuilder but not for JDevelopper 3.1. The installation wizard doesn't recognize JDeveloper 3.1 as a valid JBuilder platform. Do you know it is possible to integrate the KL classes into JDeveloper 3.1 ?
Thanks

Does it make sense to integrate these >>classes framerwork in a JDevelopper 3.1 >>project ?JDeveloper supports all types of JavaBeans.
If you need any particular component / set of components from any vendor, you can install it onto JDeveloper's component palette (Tools | Configure Palette...).
Is it a complementary or a concurrent >>framework ?The JClass components provide GUI controls -
Not what we call a framework.
Oracle Business Components for Java is an
integrated XML & Java based framework for
creating business applications. Business Components are meant for middle tier deployment and as such do not have any UI.
The UI comes from the Business Components clients.
As for is it "complementary or a concurrent",
I would say possibly complimentary to the
InfoSwing components, but definitely not
at all related to Business Components.
KL propose JClass SwingSuite and JClass Field. Is it possible to easily integrate (link with) these classes with business components generate by JDeveloper 3.1 ?Read Above.
Business Components have NO UI.
Clients of Business Components have the UI.
JDeveloper provides wizards to create
Thin client JSP based UIs and InfoSwing based UI's. You can code / design any UI you need using any GUI components you need.
Do you know project with both JDeveloper >>3.1 and KL Classes ?I know some people use components from the KL Group, but no details.
KL offer integration for JBuilder but not for JDevelopper 3.1. The installation wizard doesn't recognize JDeveloper 3.1 as a valid JBuilder platform. JDeveloper is NOT a JBuilder platform.
Do you know it is possible to integrate the KL classes into JDeveloper 3.1 ?Yes, you can integrate any set of JavaBeans into JDeveloper by selecting the menu:
Tools | Configure Palette...
I am not sure what JClass install does, so there may be more steps required. Please request JDeveloper integration from the KL Group.
I hope this helps,

Sharing BC4J components

In JDeveloper, I created a project that contains a business component package called "common". This package will contain reusable BC4J components that I want to be used by other projects. What's the best way to do this? Would I just deploy this "common" business component package to a JAR file? Would I deploy it to a JAR file and then bring it into other projects? If so, how can I have an application module in another project recognize these reusable BC4J components so that I can use them? Any best development practices are welcomed.
--Quoc

Sharing components is a good design pattern to follow. And from your description, you are already on the right track. Put your shared components in a single project, then deploy the class files to a jar file. In your other projects, add a library containing the jar file(s) that you just created containing your shared business components. Then in the context menu for either the jpr or jpx file, there is a menu item called "Import Business Components..." In the file dialog that comes up, navigate to your jar file and select the package xml file and click ok. This should bring the shared components into your new project, which you can now use freely.
Hope this helps.
