Import POJO create Entity Object?

Is it possible to import a POJO and create an Entity Object + table from it?

Hi,
you cannot create Entity Object from POJO but you can use POJO based model to generate Data Control and work with it "like with Entity Object" in view layer.
example: http://www.oracle.com/technology/products/jdev/tips/fnimphius/pojopagination/index.html

Unable to create entity object in JDev 10.1.3(R12)

Hi,
I am Unable to create entity object in JDev 10.1.3(R12).Everything else works fine but not the EO creation.THe option for selecting table,synonym are disabled when I try to create new entity object.
Please let me know if you any of you had the same problem and resolved it.

Sudhakar,
The (R12) in the thread subject line leads me to believe that you are asking this question in the wrong forum. OA Framework has its own [url http://forums.oracle.com/forums/forum.jspa?forumID=210]forum that you should use.

Unable to create Entity objects for tables in TimesTen database using ADF

Hi,
I am not able to create Entity and View objects for tables in TimesTen database using ADF. I have installed TimesTen client on my machine.
I have created a database connection by using connection type as "Generic JDBC" and giving driver class and JDBC URL. I am attaching screen shot of the same.
I am right clicking on Model project and selecting New option after that I am selecting ADF Business components and in it I am selecting Business components from tables and there I am querying for tables.I am getting list of tables and when I am trying to create a Entity object from the table after clicking finish Jdev is closing by itself giving an error.
Can anyone please help me how to create Entity objects for tables using TimesTen as database.I might be missing some jars or the way I am creating connection might be wrong or any plugins required to connect to TimesTen.

What is the actual error being given by Jdev? Are you sure that the JDBC connection is using the TimesTen JDBC driver JAR and not some other JDBC driver or the Generic JDBC/ODBC bridge?
Is ADF even supported with TimesTen?

How to create Entity object for Non Database Object.

Friends,
I have a requirement something like, I will be getting some huge amount of data from external system via CORBA, I have to display the data in jsff page in <af:table>. My requirement is If User updates any of the row I need to identify what are all the rows user updated and Need to invoke again a CORBA call for only UPDATED Rows.
Basically here, I am not dealing anything with the Database, I assume using Entity we can find out a status of the row whether the row is updated/deleted/created .
How can I create an Entity object in this case.
Any help will be highly appreciated !!!
Thanks

The basics steps are described here http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/bcadveo.htm#sm0328
and here http://download.oracle.com/docs/cd/E14571_01/web.1111/b31974/bcadvvo.htm#sm0341
You need to change the underlying data source from pl/sql to meet your requirements (CORBA).

MySQL Jdeveloper 10.1.3 Create Entity Object problem

Hi,
when I try to add new Entity Object in model i get:

If i want to create bussines component from table everything is ok. But there is a
problem if I want to add some new Entity Object.
Any solutions?
Thnx.

This works ok for me so I don't think its a Jdev 10.1.3 issue - more likely a configuration / version issue.
I'm using MySQL 10.0.15; mysql-connector-java-3.3.11-bin.jar
Below are my configuration notes - I never encountered this error, but thought I would share my config notes to possibly help review a config that is working:
Oracle Jdeveloper Tools | Default Project Properties
1.     Set up MySQL User Library - Configure JDeveloper to work with MySQL Connector/J Download MySQL Connector/J 3.0.11 and copy the JDBC driver JAR file to a known location, such as /jdev/lib From the Tools menu, select Default Project Properties. In the tree view, select Libraries. In the right pane, select New. The Create Library dialog will be displayed. Name the library MySQL JDBC. Set the location to Users Libraries. Click Edit for the Class Path. The Edit Class Path dialog is displayed. Click Add Entry. The Select Path Entry dialog is displayed. Navigate to the JAR file for the MySQL Connect/J JDBC driver (it should be called something like mysql-connector-java- -bin.jar). Click on the .jar file and click Select. Click OK; Under Libraries, ensure MySQL JDBCchecked
2. To use MySQL with BC4J: Add the MySQL JDBC JAR file to <JDeveloper10.1.3>\BC4J\lib directory (note there are some other posts on this topic)
thanks
Tom
PS - also noticed in your message:
com.mysql.jdbc.Ststement
probabley should be 'Statement' - was this something you typed in your config - if so, could possibly be a type-o

Creating Entity Object from Service Interface - JDeveloper version 11.1.1.3

In our project, we don't intend to have any JDBC connection to a database and want to create all my entity objects using SDO web services deployed in a remote server. I could create an entity object based on a SDO web service deployed in the standalone WL server successfully. But at the time of Development,when I select ADF Business Component --> Entity Object, it always takes to a screen that prompts for a JDBC connection, if you have no connection defined in the project yet. To bypass this, I need to create a valid connection to a local DB and then I can go the next page that prompts me to to choose service interface and asks for a WSDL URL. How do I get around creating a JDBC connection and create a service interface based data source directly?
To get around this issue, I created a connection to a local DB by providing a wrong password to make sure that we don't need a valid db connection. The application module (Business Component Browser) works fine when the DB connection is broken. But when I create a JSF page and put the data control there, if we don't have the DB connection established it gives error during deployment.I tried deleting the unused connection, but that gives a lot of errors during deployment. My question is;
1. How can I create a service interface based data source by-passing the requirement for a connection?
2. If that's not possible - how can I cleanly delete the JDBC connection and all it's dependencies, so that, it deploys and runs without error

Frank,
Thanks for your response.
I have made some progress in last two days and solved some of the original issues. I deleted the fake JDBC connection from connection.xml that I had to use to go to the second screen that lets me select the WSDL for the service interface. After that, I checked off the "Auto Generate and Synchronize ..." option from Application --> Application Properties --> Deployment. (thanks to Steve Muench's blog post on this subject). After that, I could deploy the JSF page and the page shows up with no problem.
However, when I try to run the App Module that was created from the WSDL (service interface), it brings up a pop-up with heading "Password Required" that says "Enter the password for" and asks for a user name and password (not sure what they are as they take any value and takes me to the next screen). After that, I can open the View and navigate through it. When i change some data and try to commit - it makes the change to the data and stores in the DB but gives an error saying "(oracle.jbo.NotConnectedException) JBO-25200: Application module is not connected to a database."
Also, the data control created from the service interface had operations called Commit and Rollback. I used the Commit on JSF page and that does the exact same thing too. Any idea?
Also - when we consume a SDO WSDL to create the entity object - how can we access the SOAP Request and Response objects? We have to implement WS-Security by instrumenting the SOAP header and need to get a handle on that. Is there a mechanism similar to JAX-WS handler framework for SDO?

How to create entity object (Business Component) using service interface

Hi,
I have tried to create one entity object (ADF Business Component) in JDeveloper 11g using service interface option instead of database schema but getting Failed to read service WSDL URL: http://....?wsdl message.
I have tried with axis default service Admin & Version wsdl and got same error message.
Regards,
Devang

Hi,
+"Oracle ADF Business Components application modules offer built-in support for web services and for publishing rows of view object data as service data objects (SDOs). This means that you can use an application module both as a local component and as a remotely accessible service, thereby using the same component to support interactive web user interfaces and web service clients. Entity objects that you create in your local Business Components project can utilize SDOs that the service-enabled application module exposes on its service interface."+
This means that you don't use Axis services but ADF Business Components Services. I am not sure this functionality made it in Boxer, but surely will in the next

How to create Entity Object when connecting JavaDB in Jdev 11g

I use Jdev 11g to connect JavaDB. When I use the BC4J wizard to create EO and VO, I only can see VO, the EO is empty.
any ideas?
Thanks

In the Application Navigator, right-click the project in which you want to create the entity object and choose New.
In the New Gallery, expand Business Tier, select ADF Business Components and then Entity Object, and click OK.
If this is the first component you're creating in the project, the Initialize Business Components Project dialog appears to allow you to select a database connection.
In the Initialize Business Components Project dialog, select the database connection or choose New to create a connection. Click OK.
On the Name page, do the following to create the entity object:
Enter the package name in which the entity object will be created.
Click Browse (next to the Schema Object field) to select the table for which you want to create the entity object.
Or, if you plan to create the table later, you can enter a name of a table that does not exist.
If you manually entered a table name in the Schema Objects field, you will need to define each attribute on the Attributes page of the wizard. Click Next.
When you are satisfied with the table object and its corresponding entity object name, click Finish

OA Framework problem to create Entity Objects

Hello my friends!!!
I´m starting to work with OA Framework and I have a problem somewhat complicated.
When adding a new entity Object Database the option Database Objects is disabled can not select the table.
View the link:
https://plus.google.com/photos/105051623226021373169/albums/5727536008728326817?authkey=CPf33qfkz-jUqgE

Before you come to the above screen, it might have asked you for database credentials. There you need to provide the username and password. Then in the following screen(the screenshot you gave), just above the Tables, views etc checkboxes you can see a poplist called Database Schema with available schemas in the selected db.
If the EO wizard didn't ask for any db then you first needs to create a connetion in JDev with connections manager.

Can we create entity object based on a text file on the OS?

I understand you can interface with files using webDAV. Can we just create a entity object with source to a text/xml file on the OS instead of a table?

Have a look at the URL data source (under new->business tier->web services) - it allows you to create a data control based on an XML or csv file.
http://technology.amis.nl/blog/?p=1592
You can also create a data control based on a Java class that interact with a file.

There is nothing 'urgent' in this forum. We are all volunteers spending our spare time helping out other users. If you have an urgent matter, you have to open an SR with sopport.oracle.com
If it's urgent, then why don't you provide information needed to answer the question.
Which jdev version do you use?
What is the use case?
To answer your question: A look into the docs http://docs.oracle.com/cd/E35521_01/web.111230/e16182/bcadvvo.htm#sm0341 and http://docs.oracle.com/cd/E35521_01/web.111230/e16182/bcadvvo.htm#sm0338 holds the answer to it.

Create Entity Object from Service interface?

An option for creating an EO is to use a "Business Components service interface". Is this referring to a App Mod service interface, web service WSDL or what? Am having a real problem attempting to decipher this and cannot find any mention of how to do this in the doc. Any help is appreciated.
Thanks for a quick response - or for that matter any response - Casey

Additional info:
Created a simple AM - Emp and Dept for VOs in the data model. Added a simple service method to the AM - input String, return String and is exposed via the client interface.
Followed the following steps as per the doc (Fusion Developer's Guide for Oracle Application Development Framework) to create a service interface:
To create the web service:
+1. In the Application Navigator, right-click the application module and choose Open+
AppModule.
+2. In the application module overview editor, select Service Interface from the+
navigation list.
Problem - I do not have a 'Service Interface' in the navigation list.
So how do I create a service interface - what have I missed?????
BTW - Using JDev 11.1.1.0.1
Thanks - Casey

How can we create an entity object using multiple tables?

Hi All,
I'm a newbie to OAF.
I'm trying to create a simple page using OAF.
While creating Entity object, there is an option to add the database objects from which we can create our Entity Object.
There we can enter only one database object.
If suppose I need to create a Entity object by using mutiple data base objects, how can I add other database objects?
Is there any option for multiple selection of database objects there?
Thanks in Advance

User,
a). You should use the [url http://forums.oracle.com/forums/forum.jspa?forumID=210]OA Framework Forum for this question.
b). Entity objects always correspond to a single table. I think you want to create a View object instead.
c). Really, you want to be using the OA Framework forum.

Dynamic Creation of Entity Objects (ADF Business Components)

Hi All,
We have a requirement to create Entity Objects for the dynamically generated tables in our application and at the same time bind them to different views.
Our product create multiple tables at runtime with some sort of naming convention, and we couldn't find a way in JDeveloper to generate entity objects for the tables created dynamically.
Please provide some pointers if you have experienced or worked on similar requirement.
Thanks,
Nikhilesh

Thanks for the help Sudipto.
The link which you have shared, describes the creation of an entity object and then modify the operations like Delete Update and Insert etc to be performed on the entity object by creating IMPL classes and implementing certain interfaces.
But I need to create Entity objects dynamically. My application creates new tables for some functionality at the run time and I have to create Entity objects for those new tables as soon as the new tables are created.
I was just wondering if, there is any API available for creating the entity object from Java code instead of invoking the wizard in the Jdeveloper.
