Problem on Business Components

Hi,
i repost this problem because i didn't succeed on resolev it. See below :
Business Components: Unable to find referenced object
Object: easyges.commercial.eos.affaires.
Owner: easyges.eos.GdaDemandeAffectationPFk1Assoc2
BC Project: easyges.view.ViewController
This appears in he message log window on opening the application.
What can i do to correct this issue?
Thanks for any help,
DAVID

Sounds like the association GdaDemandeAffectationPFk1Assoc2 references an invalid (missing, renamed) Entity Object. Open the association file in the Source view and observe for warnings/errors indicators - these are the yellow/red indicators on the scroll bar. Alternatively selecting View | Status should produce a "No issues".

Problems Customizing Business Components

Hello, I have BC4T aplication, and i want to customize it. I have created a new extended entity from the old ones, and his view, the problem is I don4t know if I could inset new rows, because always says me that the view is read only and it doesn4t, i supose that if is extended i can4t insert new rows?
Can anyone help me and tell how can i do to solve the problem?
Thanks.

You can insert new rows into the extended View Object or a View Object created on top of extended entity.
Make sure that the entity is not marked as Read Only.
select the extended view object and right mouse on that to select edit view object
In the Entity tab make sure that the Read Only check box is not selected.

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!

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 :

I'm using Jdeveloper 11.1.2.4 on windows.
Please suggest what i could be doing wrong.

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.

Problems with Logical Components

Hi All,
I am having problems with Logical Components with our project. We are implemeents SAP HCM and we have defined a logical component Z_ERP for the ECC server. now when you look at the transaction from SOLAR02 it seems they also have a logical Component SAP Learning Solution that is assigned to them. what could be the cause of this???

Hi Trevor,
If you brought them in from the Business Process Repository, the logical component is going to be the default one. If you want to use your own, you need to replace the default one with yours.
You can do this in SOLAR_PROJECT_ADMIN by going to the System Landscape tab > Systems tab > highlight the SAP Learning Solution logical component row > press F4 > replace it with Z_ERP.
If for some reason SAP Learning Solution isn't listed as a logical component you may have to add it, you can also just go to SOLAR02 > Edit > Replace Log. Comp > Enter SAP Learning Solution in the top box and Z_ERP in the bottom one > click Save.
regards,
Jason

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.

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 ?

JBO-25001 Business Components Error

Hi to all,
I am experiencing some VERY STRANGE behaviour in JDeveloper ADFBC.
I am using Jdeveloper 10.1.3.1.0.3984 to build an application using ADF and Business Components.
I have four tables, JAAS_USERS, JAAS_ROLES, JAAS_REALMS and JAAS_MAPPINGS. The only associations are that JAAS_MAPPINGS have JAAS_USERS_ID, JAAS_ROLES_ID and JAAS_REALMS_ID.
I created my entities (package: datamodel.entities) and i have specified that JAAS_USERS entity use a DBSequence for USER_ID. Please note that i included control hints for every entity.
Then i created my first view (package: datamodel.views), called JaasUsers
that simply selects all attributes of the entity.
I then created an application module (package: datamodel) and i included the view. When i test the application module everything is fine!
I created a jsf and i dragged the view as a table -> read only table and everything was fine.
I then run the page and again everything is fine.
I then realized that i needed to change the control hint for some columns. Instead of changing the control hint of the entity (JAAS_USERS) i changed the object view (JAAS_USERS).
From this point and on NOTHING WORKS!!!!!!!!!!!!!!!!!!!
Here is the error message:
(oracle.jbo.common.ampool.ApplicationPoolException) JBO-30003: The application pool (.110255D7D2E) failed to checkout an application module due to the following exception:
----- LEVEL 1: DETAIL 0 -----
(oracle.jbo.JboException) JBO-29000: Unexpected exception caught: oracle.jbo.JboException, msg=JBO-29000: Unexpected exception caught: oracle.jbo.NameClashException, msg=JBO-25001: Name JaasMappings of object type Attribute already exists

----- LEVEL 3: DETAIL 0 -----
(oracle.jbo.NameClashException) JBO-25001: Name JaasMappings of object type Attribute already exists
Please help me becuase i don;t know hot to fix this BUG!

Hey ppl , I got an exact similar error when trying to migrate from a 10g R2 to R3 version in Jdeveloper. Quite irritating this error,
Well i guess most would have figured this out , but for benefit of all , theres a slightly easier way to tackle this ( JDEV Release 3)
in the Application Navigator view Double click your Association , within association properties un-check your expose accessor checkboxes for both the source and destination .Apply changes and do a compile. If it is required , jdev will throw an error. Simply follow the process again and check the Expose accessor boxes again. This solves the problem most of the time.
Main advantage being , you can avoid the tedious task of manually changing the xml information on Notepad or the kind.
Hope this helps....

Error loading business components

Hi,
When I start JDeveloper I get message "Error loading business components".
Does it have any impact on further activities ?
How to correct this ?
Mark

I have similar problems in latest JDev 10.1.3 update 3.
In JDeveloper 10.1.2 this happened on VO based on entities from different packages.
In this version it seems to happen after the garbage collection does its job (I'm supposing).
What's more annoying is that in JDev 10.1.2 I had a workaround (open a simple VO when entering the IDE) and even when the error occured, you could stll enter all model component and their classes in edit mode.
In JDev 10.1.3 it's a blocking error, ALL model components become read-only + their classes (EntityImpl) are NOT reachable and the Data component palette is unusable??
The only workaround is to reopen the IDE??
Thanks
Fred

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. Now I want to deploy the Business Components as EJB to OAS 4.0.8 and want to run the front end as an Applet which will connect to those EJB Session beans stored in OAS. 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>

Business Components Load Error

Hi.
I'm using JDeveloper 11.1.2.1.0 and I can see the following message in the Message log;
Business Components: Load error - (null)
Business Components: Load error.
Object: (null)
With a reference to the Model jpr file for the project.
The application runs ok despite this message, but I'm concerned there may be problems lurking. I'm guessing this may be a hangover from attempting to remove a View Object definition from the Model project - which itself seems quite problematic (running into caching problems etc).
So, does anybody:
a) know how to resolve this load error issue and / or remove the null object reference
b) know of any problems it may cause if it cannot be removed
Thanks for your help.

Do you have a source control system (svn, git,...) you use with the application?
The Model,jpr file is corrupt which may cause trouble later. Right now everything looks working, but there might some display problems when you open e.g. the application module or VO.
Save the current (corrupt?) jpr file and try to restore it from the repository until you find one which loads without the problem. Once you have on select the project in the application navigator and click on refresh (ctrl-r). This should add missing content back again.
