• EJB or ADF (with the HELP of REST), the 12 c ADF business components

  Hi all

  I have a simple question to ask. I need to create a project to expose Web services from another project and third party possible.

  I need to use Rest services producing Json.

  So my question is: can I create my Web services using EJB or ADF business components? That who and why?

  EJB seems to be a little more simple/fast to implement.

  Best regards

  Luis Cabaco

  You have experience in the use of EJB or ADF BC in other projects? This could influence your decision.

  This moment (12.1.3) to produce the JSON ADF BC, you will need to code the solution.

  The plan should provide declaratively to expose REST JSON ADF BC in the next 12.2.1 release.

• ADF business components

  Hello

  In Jdeveloper 11g from, we have many ways to create models and objects of the base entity.

  For example new slot > > ADF components we have two choices a) create table Table b) ADF entity objects ADF business components

  My question is: what is the difference between the two and which is more standard and recommended method of creating CRUD application?

  Thank you

  Hello

  It's like asking which way in Rome. The result is the same that you find yourself in Rome.

  The business components of table creates EO, VO, and AM only once and it is easy to start (a beginner option).

  Table OS, this is for when you want to create the template manually. If you are a developer experienced ADF BC who knows how to build from VO of entity objects, but also associations and view links manually then this option more puts you in control, so to speak. (option expertise and probably my choice)

  But as said, the end result is the same, you find yourself in Rome.

• What is wrong with this sequence, it does not work when, after 3 inserts, I add a new record with the trigger it gives an error.

  Mr President.

  What is wrong with this sequence, it does not work when, after 3 inserts, I add a new record with the trigger it gives an error.

  --SL_CUSTOMERS table data
  
  
  INSERT INTO SL_CUSTOMERS VALUES(1,'Kamrul Hasan',NULL,NULL,'Moghbazar', 'Dhaka','0456789123',NULL,NULL,NULL,'Y',NULL);

  I find the solution by creating a function before the triiger

  as below

  CREATE SEQUENCE  "ALIZA"."SL_CUSTOMERS_SEQ"  MINVALUE 1 MAXVALUE 9999999999999999999999999999 INCREMENT BY 1 START WITH 1 NOCACHE NOORDER  NOCYCLE ;
  
  CREATE OR REPLACE FUNCTION get_SL_CUSTOMERS_vId RETURN VARCHAR2 AS
  BEGIN
     RETURN SL_CUSTOMERS_SEQ.NEXTVAL;
  
  END;
  /
  
  CREATE OR REPLACE TRIGGER SL_CUSTOMERS_TRG
  BEFORE INSERT ON "ALIZA"."SL_CUSTOMERS"
  FOR EACH ROW
  DECLARE
  dummy VARCHAR2(200);
  BEGIN
    dummy := get_SL_CUSTOMERS_vId();
    :NEW.CUSTOMER_ID := dummy;
  END;

  It works very well

• Simple question on the passage of ID variables in a url after you add a new record

  Hello;
  I know it's a simple question, I have a brain block. I'm going from a form and insert a new record in the db, but after I insert the new record, I want to pass the ID variable that gets are entrusted to him. How can I do this?
  
  It's my code to insert:
  
  < cfset EventDate = "#DateFormat(form.eventDate,"mm/dd/yyyy") #" >
  < datasource = "" #APPLICATION.dataSource # cfquery "dbtype ="ODBC">"
  INSERT INTO events
  (title, eventDate, eventTime, location, contact, telephone, fax, email, URL, sponsor, body)

  In the cflocation I want to pass the variable ID, how about a new record?

  Try this. This will select in the query exactly what was inserted just enter the id and pass id just to get in the variable. If two people fill out the form at the same exact time, that assure that they are redirected to the appropriate page.

• How to create a form that adds information to a list on the site of the muse?

  Hello

  I need to create a form for my site of muse. When the form is submitted the information needs to go to a table or database or the list on this site of muse.

  For example, a customer would go on my site and do not want to publish information on what they are looking for. They fill in their details and what they are after and click on submit. Such information would then appear in a list or a table containing information of other customers who submitted information.

  Is this possible? Is it possible to do in Affairs Cataylst? Any assistance or other means would be appreciated.

  CN

  Hello

  Yes it is possible with BC. You can either use the form of Muse or create a form in British Colombia, and then insert the form html code in the Page of Muse.

  Once the user submits the form, a notification would be triggered for you that would show the summary form as what the user has filled in the details.

  In CRM, submitting a form creates an action in respect of the user entity. You can access the case and see related information. In BC CRM, you can directly access all cases and use the filter options to filter with date etc. Alternatively, you can generate a report on the use of the form or the case where he would list details of the user and the field values that the user has submitted.

  Please note, published Muse site are web hosting sites, which does not include the feature of CRM/CMS in order to get the CRM, you must upgrade the site which is the plan of site different from those you get with your subscription to the CC.

  In addition, I suggest try all features with a place to test first and then, after finalization, you can upgrade to a paid plan.

• ADF business components Type map Oracls vs Java

  What advantages and disadvantages of each one card
  
  I thank in advance

  Take a look at this link in the developer's guide:
  http://docs.Oracle.com/CD/E16162_01/Web.1112/e16182/bcintro.htm#sm0062

  The scope of Java to map Oracle and Oracle areas type plan manage numeric data differently. When you create a new application of the type mapping default Java extended for Oracle maps the digital data to the Java.Math.BigDecimal > class that inherits from java.math.Number. The default value of Java.Math.BigDecimal corresponds to the way that web view Fusion application layer, consisting of elements ADF Faces, retains the alignment of digital data (such as numeric values > posted by ADF Faces of fields on a web page). Whereas the areas of the Oracle type that maps digital data from the oracle.jbo.domain.Number class, may not display the data with alignment scheduled by some ADF Faces > components. Apart from this alignment problem, the plan of type Oracle areas remains a valid choice and applications without ADF Faces components will work without problem.

• ADF business components: persistent negative IDs in the database

  Hello
  
  We use ADF 11 g with ADF BC as the model layer. All our database tables have a column ID, which is populated by a sequence and never shown to the user. ("IDs techniques".) In British Colombia ADF we have configured our entity objects with the attribute Id set as primary key. The type of the attribute is set to "oracle.jbo.domain.DBSequence". On the tab sequence, we set the name of the sequence in the sequence that corresponds to the table (we have a sequence for each table in the database).
  
  Our problem is the following. If we create a new record in our ADF Faces UI and a business on the database rule generates an error during validation after which correct us the error and resubmit the registration, a record with a negative identification gets in the base. If there was no error in business rule, we get an ID that corresponds to the 'nextval' in the sequence, as expected.
  
  Even though I know that ADF BC uses negative ID in the cache of objects entity for new records, I have no idea how and why these negative ID end up in the database. So far, they have been any problem in the database. But since this is unexpected behavior, I'm not entirely sure that the negative ID will not cause problems in the future. My questions:
  < ul > < li > is this design 'by' behavior or is it a bug? < /li >
  < li > if it is "by design": these are negative IDs guaranteed as being unique? < /li >
  < li > could it be caused by a configuration error in our model project? Where should I start looking for such a mistake? < /li >
  < li > could it be caused by a configuration error in our database? Where should we start to look for such a mistake? < /li >
  < li > would it be a bug in the ADF BC? < /li > < /ul >
  
  Best regards
  Bart kummel

  Bart,

  (1) it's by design
  (2) No.
  (3) No.
  (4) No.
  (5) no

  ;)

  Now for the explanation. Sequence name you set up is just for information purposes only - it is not actually cause ADF fill the value using the sequence. To do this, you must either write database triggers or you can use an extension framework class to have occur in the model layer - in my view, such an extension class is documented in the developer gude (search for DBsequence, I've not worn to hand at the moment). Negative numbers are only temporary placeholders.

  ===========================================================================================================================

  Could please help what is wrong in the code, I followed all the steps as stated in the guide, but the table advance, the problem starts whenever I click on the button Add a new row for the creation of new line.

  I couldn't understand what was wrong with the code.

  Thanks in advance,

  Suman

  Suman,

  A few points:

  1. Why do you call handleCurrencyChangeEvent in the event to add a line? Simply set the useful, likely of the values in the line it himself.

  ex:-instead of calling the handleCurrenyChange method, simply add the below lines inside the createDetailRow()

  dtlrow.setAttribute ("ExchangeRateTypeRender", Boolean.FALSE);

  dtlrow.setAttribute ("ExchangeRateDateRender", Boolean.FALSE);

  dtlrow.setAttribute ("ExchangeRateRender", Boolean.FALSE);

  2. it looks like you have on the field of the currency and that fireAction handleCurrencyChangeEvent action method is called, right?

  Instead of using dtlVo.getCurrentRow, use the code below:

  public void handleCurrencyChangeEvent(String eventRowSourceParam)
    {
    OAViewObject pvo = (OAViewObject)findViewObject("xxCurrencyPVO1");
    OARow row = (OARow)pvo.first();
  
    OAViewObject dtlVO = (OAViewObject)findViewObject("xxEcreditCardDtlVO1");
  
    //OARow dtlRow = (OARow)dtlVO.getCurrentRow();
    OARow dtlRow = (OARow)this.findRowByRef(eventRowSourceParam);
  
    String  currency = (String)dtlRow.getAttribute("CurrencyCode");    // NULL POINTER EXCEPTION
  
    if ((currency == null) || ("AED".equals(currency)))
    {
    row.setAttribute("ExchangeRateTypeRender", Boolean.FALSE);
    row.setAttribute("ExchangeRateDateRender", Boolean.FALSE);
    row.setAttribute("ExchangeRateRender", Boolean.FALSE);
    }
    else
    {
    row.setAttribute("ExchangeRateTypeRender", Boolean.TRUE);
    row.setAttribute("ExchangeRateDateRender", Boolean.TRUE);
    row.setAttribute("ExchangeRateRender", Boolean.TRUE);
    }
    }
  

  In the controller:

  if((ADD_ROWS_EVENT.equals(event)) && "AdvTblRN".equals(pageContext.getParameter("source")) )
  {
    am.invokeMethod("createDetailRow",null);
    am.invokeMethod("initPVO");
  } //**End Add Row Button**
  else if ("currCodeChangeEvent".equals(pageContext.getParameter(OAWebBeanConstants.EVENT_PARAM)))
  {
    String eventRowSourceParam = pageContext.getParameter(EVENT_SOURCE_ROW_REFERENCE);
    Serializable[] params = {eventRowSourceParam};
      Class[] paramTypes    = {String.class};
    am.invokeMethod("handleCurrencyChangeEvent",params, paramTypes);
  }
  

  3. Why do you call initPVO when it is clicked on the Add line? Are you calling not just in the PR?

  You could call it once in the PR and let. When you call it PR, you may need to remove the handleCurrencyChangeEvent of this method call.

  See you soon

• [ADF, JDev12.1.3] How to set attributes for new records in detail your (by program) in a panel of master / detail tabbed?

  Hallo,

  in a fragment that I have a tabs including the 1st tab panel contains an af:form (created from a master VO) while the other tabs each contain an af:table (created from a VO detail).

  When the fragment is used in design mode , I need to set some attributes (hidden) for each VO.

  I guess I can begin to insert before the fragment, in the workflow, the operation "Create with Params" for the master VO.

  But who should I set the values for the fields the other VO's hidden when the user create new records?

  Some fields of VO can be set taking values directly from session and pageFlow scope while the value must be calculated for other fields.

  Thank you

  Federico

  

  Retail vo was create with Potsdam too. You can use what you can do to master VO. link the button to detail to a bean and calculated method to set the parameters before running the createWithParam.

• Commit_form creating problem with shutter release once - new - Record - Instance

  Hello friends,

  I use Oracle forms 6i. I have a block of multiple data. I wrote commit_form in a times-news-record-instance of the data block. When I run the form on my instance the form does not open.

  But when I comment on this code, the form opens to the instance. What could be the problem?

  Also is it a condition that I can specify if the block of the data set is null when I open the form?

  Hello...

  In When-new-folder-Instance, check if the lock status is NEW. If not, then just apply COMMIT_FORM;

  Try this code in your trigger

  IF: SYSTEM. BLOCK_STATUS = 'CHANGE '.

  THEN

  COMMIT_FORM;

  END IF;

  Should work for you.

• Active Data Guard on DB 11 g and ADF business components

  Does anyone has experiences using business against a data source Active Data Guard components? Y at - it something ADF BC specific, you might need to know/set up regarding the parameters of the Application Module. Of course, we would read only your with her. Sorry it kinda turns out to be a beautiful finished question just want to know if it's a go or one thing more than any other possiblity.

  TheOtherDave,

  It should work perfectly. One thing you will need to know is the passivation of State mechanism used by ADF BC can use a store based on files or DB-table-based store. Obviously, if you want to use the DB-table-based store, you will have to configure it to point to a database where you can write to DB tables, which will be probably different from your database pending of DG. Otherwise, I can't think of specific issues (but I don't him have not personally tested).

• ADF business components: how to apply where Clause to the new lines

  Hello world.
  I develop Web Application from merger under Jdeveloper 11.1.1.0.1.
  I read this post http://blogs.oracle.com/jheadstart/rowmatch/
  And I have a question. How should I configure rowmatch if I instance the same viewobject except 2 2 viewobject defined on the same entity.

  If you use view criteria to make your filtering and scoring mode 'filter' of the Victoria Cross to be "Both" (database and in-memory), then the framework will automatically use your filter to filter the lines again without having to write code or use your own rowMatch object.
