Entity object with Step by step explanation

Dear friend,
i want to make entity object using ADF framework anyone can give me the PDF or URL

Are you talking about ADF BC entities:
http://www.oracle.com/technology/obe/obe11jdev/bulldog/ria_application/developriaapplication_long.htm
Or JPA entities:
http://www.oracle.com/technology/obe/obe11jdev/bulldog/ejb_jpa_jsf/ejb.html
Both and other tutorials are linked from the tutorials link here:

  • Best way to validate multiple entity objects with each other

    I have the following scenario.
    There is one entity object with the following fields.
    Name
    Start Date
    End Date
    My requirement is to validate the dates in the entity do not overlap.
    What is the best way to achieve the same.
    This validation should be fired when we commit, since the user should be allowed to change the dates freely between entities.(Validation should not kick off when the current row changes)
    Thanks

    For this to achieve there is a concept called Effective Dated Entity Objects in Oracle ADF.

  • Validation of attribute in Entity Object with List Rule Type

    hi all
    I have an entity "currncy" and I want to make
    a validation in entity level on its attribute "Isdefaultcurrency"
    which is boolean.
    Entity Object : Currency
    attributes :
    1. Currencyid DBsequence
    2. Currencyname String
    3. Isdefaultcurrency, Boolean, CheckBox
    Rule Type : List
    Operator : In
    List Type : Query Result 'select ISDEFAULTCURRENCY from currency where ISDEFAULTCURRENCY=1'
    I want when user insert in table, validation checks the attribute 'Isdefaultcurrency'
    was true then show the error message that there was default currency and if you
    want to set it to true (or default) you must change another record that was true
    and uncheck it then back to current record and will make it true and
    there is one record in my table that its attribute 'Isdefaultcurrency' must be true
    this validation that I used , it does not work correctly and it allows to enter 2 records with
    true value for Isdefaultcurrency. In fact I want when User Enter the First record and
    set the Isdefaultcurrency to true then enter the second record and set the Isdefaultcurrency
    to true the error message will be shown.
    pleas explain it
    Edited by: Marzieh on Jan 30, 2012 9:43 PM

    Is it that you want to only allow one record in the table to have isdefaultcurrency='1'?
    yes , that is correct . I used Oracle DataBase .
    DECODE(isdefaultcurrency, 1, 1, null) please explain about it.
    isdefaultcurrency attribute has boolean Type with 0 or 1 values.
    I would like to show an error if check box was checked for the second time. The idea is that just
    one check box should be checked.
    thanks for your answer

  • Sharing same entity object with multiple viewobject problem.

    Dear All,
    I have a common entity entity object, that i am using in 4 different vo(only the where clause is different),
    I have created 4 af:table from corrosponding vos, when i am inserting some records in any of the vo then all the vo is showing the same records.. even through each vo is having separate where clause,
    But when i do this with separate eo for each vo then it works fine..
    Here i just want to do with the single eo being shared by different vo of same kind.. except where clause, Also i want to know why this issue is comming on insert? is it normal expected behaviour ? If yes then how to overcome this problem..? Pls provide any good suggestions if you have..
    Thanks & Regards.
    Santosh.

    Hi Sacha,
    Thanks.. i read it and found following
    You can globally disable this feature by setting the jbo.viewlink.consistent to the value false in your configuration. Conversely, you could globally enable this >feature by setting jbo.viewlink.consistent to the value true, but Oracle does not recommend doing this. Doing so would force view link consistency to be set >on for view objects with secondary entity usages that are not marked as a reference which presently do not support the view link consistency feature well.Now i am thinking to set it false.. but as doc says but Oracle does not recommend doing this. Doing so would force view link consistency to be set on for view objects with secondary entity usages that are not marked as a reference which presently do not support the view link consistency feature well,
    With what option should i go...?
    go with separate eo and vo..?
    Regards,
    Santosh.

  • Can I use subtype/supertype Entity Object with JHeadstart ?

    Hi,
    I am using Generalization on our entity object design, i,e : Employee(SuperType), Hourly_Employee(SubType), SalariedEmployee(SubType), Consoltant(SubType). The attributes attached below.
    All SubTypes will EXTEND the supertype : Employee.
    The questions are :
    Can JHeadstart handle the generalized entity objects ?
    How can the UI look like with JHeadstart ?
    Thank you for your help,
    Krist
    Supertype : Employee
    Employee_Number
    Employee_Name
    Address
    Employee_Type
    Date_Hired
    SubType : Hourly_Employee
    Hourly_Rate
    SubType : Salaried_Employee
    Annual_Salary
    Stock_Options
    SubType : CONSULTANT
    Contract_Number
    Billing_Rate

    Krist,
    If I understand you correctly you want to have a number of View Object attributes in a page to be accessible through 'subtabs', and want the correct subtab to be shown when the 'discriminator' field is changed. I am sorry for the confusion, I got thrown off track with all the super-subtype Entity details, but in the UI you are only dealing with ViewObject (usages), and not Entity Objects.
    Anyway, we can not generate 'subtabs'. There is a feature on our 'Enhancement list' to make the Regions have a 'stacked' property, which I think would come pretty close to what you need: you could group ViewObject Atributes together in Regions, and 'stacked' Regions would be generated as tab pages. We have not implemented this feature yet, and even if we had, you would have to change it post-gen because in your case, you would not want the end user to be able to 'switch tabs', but only a change of the 'discrimitator' field should do that.
    We have shipped some templates, though, for creating subtabs for child groups. Perhaps you could take a look if some of that code could be useable for your.
    I would suggest the following approach:
    1.) In the application structure file, create 'Regions' for all subtypes, and in the BC4J Property Editor, assign the 'subtype' attributes to the corresponding Region.
    2.) Regenerate the page. Now you should have a separate 'header' element for each subtype, containing the appropriate attributes.
    3.) Now you will need to transform those 'headers' to 'subtype tabs'. You could do that by borrowing code from our 'tabbed child' templates, or, alternatively, you could use a similar, Javascript-based technique that we use for switching between Quick Search and Advanced Search.
    4.) Finally, you should device a mechanism to change the active tab when changing the 'discriminator' column in the area above the tabs, with the supertype fields.
    Hope this helps,

  • Entity Object with Nullabl Primary Key Parts

    I posted an article on how to handle nullable PKs.
    Here is the link:
    http://radio.weblogs.com/0123729/stories/2003/05/15/entityObjectOverTableWhosePrimaryKeyMayBeNull.html
    Please take a look if you're interested in the topic.

    Most likely the record in the database has an extra white space attached to it.
    For ex:- 'Harry ' instead of 'Harry';
    If you have an extra space there then findByPrimaryKey("Harry") will not be find that record.
    You can test it launching a SQL*PLUS
    and
    select col from table
    where col='Harry'
    this would return "no rows found" if it has an extra white space.

  • ClassNotFound Exception integrating Coherence and Eclipselink with composite key entity objects

    I am hooking up coherence as an L2 cache for eclipselink in weblogic 12c (using the latest released weblogic and eclipselink 2.4.2.v20130514-5956486).  I have my application war and coherence gar packaged in the same EAR file.  For Entity Objects with single primary keys (Longs) coherence integration works as expected.  However I have several multi-part key Entity Objects that use an IdClass to represent the key.  When these objects get serialized, coherence throws a class not found exception.  I'm assuming its because the cachekey used is an instance of my applications IdClass, and the weblogic classloader doesn't have access to this.  Since eclipselink hides the cache integration with coherence, I cannot pass my classloader off to coherence (as i do with other caches i'm using directly with coherence).
    How can I get around this problem? 
    I saw this option in ExternalizableHelper.xml, but modifying it directly had no effect:
      <!-- if deploying Coherence in CLASSPATH and deploying application
           classes within a hot-redeployable archive (e.g. ".ear"), set this to

  • BC4J: problems creating view object with multiple entity objects

    Hi,
    I working with a view object which contains two entity objects with parent-child relationship like this:
    ViewObject - ParentEntityObject - PId
    PAttribute
    CId (FK)
    (- ParentChildAssociation)
    - ChildEntityObject - CId
    - CAttribute
    The 'Read Only' and 'References' options are checked for the association in the view object.
    I'm creating a new row using this view object. The parent object should be created new and the child object already exists in the database, so I'm setting only the attributes of the parent object (including foreign key).
    After creating the row I display it in a jbo:DataTable and only those attributes coming from the parent object are displayed. The attributes of the child object are not set. After a commit all attributes appear.
    The problem is, that I want to display the new row with all attributes to the users BEFORE they commit.
    I tried to set the child attributes, but they are read only by definition and even when I unchecked the 'Read Only' option and set the attributes to 'Always Updateable' in the view object it is giving me
    JBO-27008: Attribute set for CAttribute in view object ViewObject failed.
    Is there a way to make all attributes of the child object visible in the view object without committing changes?
    (JDev 9.0.2.822)
    Any help would be appreciated.
    Regards,
    Christian

    Once again the structure, sorry.
    ViewObject
    |-ParentEntityObject
    ..|-PId
    ..|-PAttribute
    ..|-CId (FK)
    |-ParentChildAssociation
    |-ChildEntityObject
    ..|-CId
    ..|-CAttribute

  • Using a polymorphic view object with binding

    Hi,
    I'm hoping there's something simple I'm missing when trying to setup up the bindings for a ADF/struts page using a polymorphic view object.
    I'm using Entity and VO polymorphism to create a Question which has different types - boolean, multi-choice, likert, etc. I have the various question types created as sub type entity and view objects and added to the app module - when added to the app module the question types are subtypes of QuestionView so they don't actually appear in the Data Controls palette. This setup is like that used in Steve Muench's examples (blog at http://radio.weblogs.com/0118231/stories/2003/02/06/constructingTheDesiredEntityInAPolymorphicViewObject.html and the related undocumented one)
    My question is, how do I get to the data and have jdev create the necessary bindings for the extra attributes the subtype questions have? Since they don't appear as available data controls I can't create a binding iterator or anything for them - short of adding them as spearate view objects (which destroys the whole point of using polymorphism in this case) is there a way to do this?
    Really, the only reason I want to use the polymorphism is so I can have different types of entity validation depending on the type. Should I just simplify this to be one entity object with one VO and put all the validation into "if else's" based on a discriminator?
    Assistance appreciated...

    How else are you planning to associate a JUTableBinding to the 'common' iterator containing all four types of rows and then selectively display them? Perhaps you'd need a custom model over the JUTabelModel that'd filter the rows out.
    I'm not sure if all that trouble is worth it given that your datasets (as far as mentioned in this post) are not large. If these tables/data has to be refreshed/executed a number of times, then you may see the overhead of four queries otherwise it should be fine as database is always faster in filtering rows than doing that in memory.

  • Add new entity object using JDBC Datasource.

    HI my jdev version is 11.1.1.5.0
    I have an adf application with JDBC Datasource connection.
    Now how can I Add a new entity object with JDBC Datasource.How can i connect to DB to map the entity object.
    Thanks

    You need to have a DB connection defined for the project to be able to create new EOs - so just define a new DB connection.
    If you already have ADF BC defined in your application - then it probably means you already have a DB connection defined - see project properties->ADF BC section.

  • Entity validation with groovy expression

    Hi,
    I'm using jdeveloper 11.1.2.3.0
    I have an entity object with two attributes "status" and "reason".
    Only in case the user select status id "4" I would like to validate that he will select also reason.
    for this I was trying to add entity validation with groovy expression.
    so I added this expression "Status== 4 && Reason == null" and also I added failure message.
    But it doesn't work as I expected.
    The error is displayed every time, also when the user select status that is not 4 and also when he select status 4 and the reason is not null.
    How should I write this groovy expression?
    Thanks

    Just to clarify,
    If you add this validation to your status attribute then it will validate that Reason is not null when you change the status to 4.
    If you want to raise an entity validation just add a new Entity Validator and the expression should be something like what you had:
    But slightly different
    Status != null ? (Status==4? (Reason!=null) : true) : true

  • 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.

  • Problem with using multiple Entity Objects in a view Object.

    Hi
    Thank you for reading my post
    I have create 3 Business components for 3 of my database tables and now
    I must add 3 tables in a View object so i used Jdeveloper Wizard to create the View Object.
    -I Add Entity Objects which are business components to this view (In Step 2 of the Create Vview Object wizard).
    -In step 3 that I add Attributes all my attributes are marked as Transient
    Can some one explain why it happens?
    I need one of those tables to be updateable and two other tables are not updateable.
    What should should i do to achieve this?
    I should say that tables does not have any database relation (Foreign Key I Mean).
    Thanks.

    Hi user505214
    When you created your VO, on selecting the second EO, you'll note at the bottom of the same page on the wizard/editor, checkboxes for updatable or by reference. By default reference is checked and this will make your second EO's attributes transient.
    In the JDeveloper Developer's Guide for 4GL/Forms programmers, the following sections outline the difference between updatable or by reference:
    7.5 Including Reference Entities in Join View Objects
    27.9 Creating a View Object with Multiple Updatable Entities
    Make sure to read 27.9 if updatable is what you want as it indicates you may need to add some additional code.
    Hope this helps.

  • Should I start with Entity Object or Java Class Diagram ??

    Hi,
    I come to J2EE / OO application development from non-oo programming world. I am still confused about what step-by-step development approach should I take ?
    Should I :
    - start with creating Entity Object from available database table ?
    - should I start with Java class diagram, followed by generating database tables, then create EO from it ?
    Could anybody please help me, what best practice step by step development approach should I take ?
    Is there any white paper / docs about this ?
    Thank you for your help,
    Krist

    Krist,
    If you are not from the OO world then you may be interested in this new site on OTN (http://otn.oracle.com/formsdesignerj2ee) There is a workshop that starts by looking at an existing datamodel and builds up from there.
    If you are starting from nothing, you can indeed start higher at the Class Model level.
    I recently started discussing data modeling on my blog (http://www.groundside.com/blog/content/SueHarper/) and there are some very good comments(feedback from readers) that may possibly be useful to you.
    If you are new to the UML modeling world, I recommend you read two very good papers by Jan Kettenis on OTN (http://www.oracle.com/technology/products/jdev/collateral/collateral10g.html) They are Getting Strted with UML Class modeling and Getting Started with UML Use Case Modeling.
    Shay pointed you to Toplink. There are a lot of resources on OTN for Toplink, including tutorials.
    Personally? I think if you have time, and if you can, start with a Class Model and perhaps a Use Case model, then you can start planning your application development from a solid base.
    Regards
    Sue Harper
