How to create PSI entity

Hi All!
I don't want to use bc4j persistance in my entity. How to create PSI persistance entity.
Samples and documentation will be appreciated.
P.S.Is it diffrence in deployment only?
Mike

Hi!
Ok! Oracle have two implementation of cmp -
BC4J and PSI. I don't like BC4J in any way...
To change type of persistance You must change oracle deployment descriptor. Take as starting point oracle JVM samples (entities/customer)
Find in doc theme about deployment descriptors. It's contain all information you need. As I say, type of persistance depends on deployement only. Nothing changed in code.
Good luck!

How to create xml entity in sap

hi,
kindly tell me process of creating xml entity in sap.

Hi Vineet ,
You can use function module "SDIXML_DATA_TO_DOM" to convert the data in internal table to XML form. This function module is used to create the structure for XML document.
After this you use FM "SDIXML_DOM_TO_XML".
Hope this helps you!!!!

How to create dynamic entity beans at runtime (experts welcome)

Hi,
i have a question that i have been trying to figure out however i am still in search of an appropriate solution and thus ask you experts for guidance...
I am developing a system to house data using ejbs.. however a have a problem i am trying to make the system very dynamic and some of the data that i am trying to store is dynamic in its nature..
let me explain: i am searching for a solution that would allow a entity ejb to have a dynamic set of properties
e.g.
DataEntity could have one or many attributes but those attributes may be string, string, int, int
or could be int, int, int
or long, long
or double..... or any configuration
this DataEntity would linked to a TypeEntity that would act as a reference to know how to store and retrieve data..
I have just come across JMX and dynamic Mbeans, and at first glance this seemed like it may be able to help but after further research i think this handles a different problem than i am facing.. (however might be wrong?)
At the moment i am using toplink as the OR mapping but have also jsut started looking into hibernate..
So far all i have come up with is to have a FieldEntity as a mappedsuperclass and have sub classes such as IntFieldEntity, LongFieldEntity.... which simple contain one field i.e int value, or long value..
. and have DataEntity have a one to many relationship with the field superclass..
the problem with this is how this gets mapped
my ideal solution would be to have a dynamic DataEntity which could be generated at runtime and have all the required attributes for the particular type..
so DataEntity would be a mappedsuperclass and then at runtime new types of DataEntity's could get spawned, database table created and OR mapping created linking?
e.g.
DataEnity1
String attribute1;
String attribute2;
int attribute3;
DataEnity2
int attribute1;
int attribute2;
long attribute3;
Has anyone ever created a structure like this or seen anything like this before?
any advice would be appreciated
regards,
fg

You cant add controls to the visual tree a runtime which persist beyond the lifetime of the application. You will have to persist an indicator to your program which tells it to add the control. Adding a control is as simple as initializing
it and adding it to a parent already on the tree. Controls can be created programmatically or using the XamlReader.Load static method. You can find XamReader.Load in Windows.UI.Xaml.Markup in windows 8.1, Windows 8.1/Windows Phone unified
projects. For old windows phone ad just Silverlight I believe it is in System.Windows.Markup.
Hope this helps.

[ADF BC] How to create an entity association to get one child

I have two entities in a one-to-many relationship (say Employees and Employee_History). Each employee has one or more history entries.
What I would like to do is have an Employee view that contains all the attributes from the Employee entity and also an attribute (or many attributes) from the latest entry in the Employee_History entity.
Is there a way I can model this with ADF Business Components?
Things I've tried:
- adding SQL in the one-to-many association to ensure only one row is returned (does work, but affects other operations like creating a new employee record)
- creating a one-to-one association between the two entities (still returns more than one record)

Thank you Steve, that works great for the hire date, but what about when you need another column from the same record as that hire date.
Would you have to use a query like this?:
select DEPTNO, DNAME, LOC, (select max(firstname) from emp e where e.hiredate = (select max(hiredate) from emp where deptno = Dept.deptno) and e.deptno = Dept.depno)) as LAST_EMP_HIRED_NAME from dept DeptAt the moment I've been able to get it working like I want to (as far as I can tell) by referencing the child entity in the parent view and using a where clause in the view's SQL to reduce the rows returned, like this (using the example of departments and employees):
SELECT Dept.DEPTNO,
       Dept.DNAME,
       Dept.LOC,
       Emp.DEPTNO AS DEPTNO1,
       Emp.HIREDATE,
       Emp.FIRSTNAME
FROM DEPT Dept, EMP Emp
WHERE Dept.DEPTNO = Emp.DEPTNO AND Emp.HIREDATE = (SELECT MAX(HIREDATE) FROM EMP WHERE DEPTNO = Dept.DEPTNO)Testing this with the business components tester, it seems to work.

you will have to create a sequence and a trigger
CREATE SEQUENCE <SEQUENCE NAME>
INCREMENT BY 1
START WITH 1
NOCACHE
/this sequence will guarantee that each requested number is unique
the trigger will select from this sequence and insert the obtained value in the new record
CREATE OR REPLACE TRIGGER <TRIGGER NAME>
BEFORE INSERT ON <TABLE NAME>
REFERENCING NEW AS NEW OLD AS OLD
FOR EACH ROW
    BEGIN
        select
            <SEQUENCE NAME>.nextval
        into
            :NEW.<COLUMN NAME>
        from
            dual;
    END;
[/CODE]
this will always take the value from the sequence, even if you already provided a value yourself
(otherwise you will first have to test if :NEW.<column name> is null, but I wouldn't do this for a key column.
if you need the generated key back for further processing (inserting it into a child table for example), you can use the returning clause on the insert statement
see the oracle documentation for more information about sequences, triggers and the returning clause

I am new to Oracle and need to know how to create a table that uses an automatic incrementation on a primay key for it's default. I need the uniqueness automatically managed by the DBMS.. This activity is know as setting the Column (primary key with identity) in Ms-SQL..
Your help would be appreciated greatly....

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).

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.

How to create index attributes in CAF Entity Service

When one creates an entity service with external persistency (local persistency on the persistency tab is unchecked) you have to create at least one "key" attribute. However, how do you create "index" attributes to improve performance. Currently, if you add custom key you must select "key" checkbox in attribute wizard when creating an attribute and this key field must be unique. This is not what I am looking for. I'd like to create a few custom keys that the contents allow duplicate.

Hi Tom,
This is a very valuable question. Yes, you can add an index for specific fields to the generated database table. You can do in the NWDS, navigate to the dictionnary view and open the corresponding database table. Now you can add an index and assign database field(s) to this index.
However: you must be aware that, if the entity is changed (i.e. new parameters are added), the database table is re-generated and the indices are lost.

Jan

BM,
If you want to import the utils package into your code, then the location of the utils package has to be in your CLASSPATH. JDeveloper uses libraries to define a project's CLASSPATH.
I'm not sure exactly what's going on here, but you might want to read the information about packages and class libraries in the online documentation. It's under:

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.

How to create entity for the table which is not having the primary key

Hi,
Is it possible to create an entity for the table which is not having the primary key.
I have to write a method in my session bean and that method must use this entity.
any websites for this.

If you are talking about processes launched from a JVM (running outside), Process is available.
If you are talking about processes already running outside of a JVM, you could roll-your-own class to provide similar functionality as Process. This approach would be platform dependent, backed by the platform's I/O scripting and therefore limited to what the platform supports for process manipulation, e.g. Linux/Unix capabilities far exceed Windows.

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

How to create 'Query Result Object' entity?

Hi Gurus,
I have come across a situation where i need to create an entity [not a value node] of object type 'Query Result Object', and set the values.
Its possible to create an entity of type 'Root object', but was not able to find a way to create other object types.
Please find below, the details of the query result object:
Component: CRMAUI
Object: AUIHANAQR
Object type: Query Result
Attribute Structure: CRMS_AUI_SRCH_RESULT_HANA
The above entity is part of the collection which in turn is the result set of a dynamic query search. Due to a particular requirement, we need to add some more entries of the same object type in the result in the 'search event' itself.
Please find below, the details of the corresponding dynamic query object:
Object: AUIQueryHANA
Object type: Dynamic Query
Kindly let me know if you have come across such situation before and please share the solution if you have any.
Your help will be much appreciated.
Thanks and regards,
Arun N K.

Hello,
In fact there is not really entities for query result object, it's entries in the result table.
So you need to modify the search to add more results, usually there are some badi to do so, or maybe you can extend the class used to perform the query in order to add some results.

Benoît
