Schema selection changed in business components

When you edit the business components in 903 you cannot select specific schemas only you own, none or all. In 902 it was possible to slect a schema.
Why has this been changed? it makes it so much more difficult to find tables and view on the database.

Jeppe Jensen

Hi Jeppe-
Sorry for the slow response, we've been awfully busy around here lately. This appears to be only a problem
with the edit wizards, i.e. the create wizards will correctly display all the user names, but when you edit the objects the
usernames are not correctly displayed. I will log a bug against this and fix it for the 9.0.3 relesae.

Enable/select/change to Business rules from Calc Manager in App settings

Hi all,
Somehow we are Unable to Expand the Planning Node in Essbase Administration Services (EAS) Console When Creating Business Rules. I am not sure is it
I am not sure, is it because of one of the application has calc settings as calc manager in under application settings in dev environment, but in other environment all applications set it as Business Rules.
I was trying to change from Calc Manager to Business rules in App settings, but it is grayed out and not able to change to Business rule from calc manager.
Please suggest me.
Thanks,

If it say been set incorrectly then you may need to update one of the relational tables for the application.
Table - HSP_SYSTEMCFG
Field - CALC_ENGINE_OPTIONS
Values - 1=HBR, 2=CalcMgr
Restart the planning application web app service after making changes.
Cheers

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

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.

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:

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:

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....

Refresh ADF Business Components

I create view(ADF business components) with my sql statiment
select e.*,d.* from scott.emp e, scott.dept d where e.deptno=d.deptno
on my first page JSP I drop ReadOnly table
on my second page JSP i drop InputForm for edit.
and so
I run my project, on first page have the button "Edit" which is bound my JSF Navigation Case with second page.
I try edit emp.DeptNo and commit change. When I back on first page i see that emp.DEPTNO changed but dept.DNAME not changed.
How I can refresh my first page that see all changed?

Hi Frank!

Editing business components

Hello guys, how can edit my business components ??
lets say i have added a new column to the table in database and i've made a new foreign key with another table, what is the best way to update these changes to my entities and view objects ?
am using JDev 12.c , thanks in advance ^^

right click on a business component package and select synchronize with db. This will add the missing column and new or changes rules to the EO. The updates to the VO you have to to by yourself (e.g. add column to VO).
And the new FK doesn't automatically result in new association or viewlink. These you have to do yourself.
If you have not written too much code you can delete the business components and create new ones from the tables again.

Database objects not displaying in Business components wizard

I am trying to create new entity object based on a table using Entity Object Wizard. But I dont see that the tables,views,sysnonyms enabled and also do not get the list of tables in the dropdown
Following are the steps that I am following :
1] in the navigator, have right-clicked and selected the "New Entity Object " Wizard Option.
2] Entered the name and the package and in the schema object lov, do not see the list of all the tables at all and also the Database Schema is disabled.
I have connected to the database from JDeveloper using database connections, but do not while creating an Entity object. Can you pls help me resolve this.
Version of Jdeveloper is 11.5.10(CU3)

Select your project in Jdev, right click and select "Edit business components project". In the new window check the value used for connection.

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!

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.
JDev 11.1.1.6

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.

at oracle.jbo.server.ViewObjectImpl.executeQuery(ViewObjectImpl.java(Compiled Code))The datasource uses the connection pooling driver class com.microsoft.sqlserver.jdbc.SQLServerConnectionPoolDataSource.
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

AutoSubmit property in business components

Hello,
I see that AutoSubmit property can be set in business components. For a VO attribute (or EO) I ca set autoSubmit = true.
But, this autoSubmit property is not automatically set in UI components generated when drag'n'dropping the same VO in a fragment. I have to change inputs autoSubmit property manually.
So, I don't understand. What for is the autoSubmit property in business components?

Yes, It is used primarily for updating 2nd UI Component based on the 1st one's value. Suppose you have two different lists of Countries and States. You should display states of the selected country in the first list.
Here you can set AutoSubmit=true for the Country list and add States list's partial refresh to the Countries list.
In this way, when value in the Country list changes, the States list will get an updated. Obviously, you will have to write the method to pick the correct list of states.
regards,
Rajan

Sharing business components across projects

i have created a project in jdeveloper that contains all my required entity and view objects. this project has been placed on a central machine. during the development phase, all the team members need to use the same project and make changes to the entity/ view objects. but the changes made by one are overwritten when the same project is saved by the other member. is there any way to get around this problem.
also, i created an entity and view object on one machine and copied the xml and java files to another machine. here i tried to include them in a new project but got errors and was unable to do so. what are the steps to be followed to include existing entity/view objects in a new project.

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?
