SOAP / REST   these are the technologies required for the Fusion Technical Consultants.

Iam a newbie in this area : i just found following are the simple samples provided by the developers.

Expose ADB BC (EO,V) as REST  WebService

The following posts lists down some set of links which are useful during Fusion Personalization.

OAF VO Extension  Sample on iExpense page

You can find the source code @  https://drive.google.com/file/d/0B1HLsOv1s5WFdkxPNEV0QWZnaG8/view?usp=sharing

I hope the images are self explanatory.

OAF - Parameterized Popup

In this article, i will show you how to implement a parameterized popUp in OAF Page.

Region Style : PopUp is available only from R12.1.3 Ebiz.

Iam considering the below requirement to work on the functionality of popUp region.


BC4J Object List :

EmpVO
DeptVO --> parameterized with DeptID


Pages:
HelloPopUPPG.xml (Shows the employee details)
HelloPopUpCO

DeptRN.xml (Shows the Dept Details) -- Shared Region

Final Result

OAF Integration with XML Report (Merge Multiple VO's)

In this sample, you will get to know how to merge multiple VO's into single XMLDocument and pass this input to RTF Template using : TemplateHelpder API to get the desired output.

RTF Template

Make sure you get the xdo files from $JAVA_TOP and move them in your myclasses of Jdeveloper


Below is the logic of the controller for the buttons in the page :

Auto-Repeating Layout (ARL) - in OAF

One of the very good feature to display a region multiple times.

As most of them aware of Table/ HGrid to display multiple records, but there is also a container to show the data repeatedly based on the VO applied.

Please find the below screenshot for same.

PG.xml Properties

Attribute Level Validations in OAF

You Can use the below method in EOImpl

    protected void doDML(int operation, TransactionEvent e) {
        super.doDML(operation, e);
        String value= getEmail();
       
        if (value==null)
        {
           throw new OAAttrValException(OAException.TYP_ENTITY_OBJECT,
           getEntityDef().getFullName(), // entity         name
           getPrimaryKey(), // entity primary key
           "Email", // attribute Name
           value, // bad attribute value
           "FND", // message application short name
           "XXCUS_EMAIL_REQ"); //
       
        }

    }

Invoking Workflow From OAF Page


Use the below method in the processFormRequest , on based on the button event.

    if(pageContext.getParameter("submit")!=null)
     {
              String PItemType = "XXHRWF";
            String PProcess = "XXPROC";
            oracle.jbo.domain.Number pitekKeyNo =
                pageContext.getApplicationModule(webBean).getSequenceValue("XX_TEST_SEQ");

            String PItemKey = pitekKeyNo.toString(); // This can be a random item key generated

            OANavigation wf = new OANavigation();

            // Now create Workflow Process
            wf.createProcess(pageContext, PItemType, PProcess, PItemKey);

            // Set Sales Order Number
            wf.setItemAttrText(pageContext, PItemType, PItemKey,"XXATTRIB", "OPERATIONS");

            // Start Workflow Process
            wf.startProcess(pageContext, PItemType, PProcess, PItemKey);
     }

Playing with conversion of dates

Frequently required script


Following code is used for the purpose of converting :  Date Input in : String format into : java.sql.Date


    private java.sql.Date stringToDate(String dateS) {

        java.sql.Date sqlStartDate = null;
        if (dateS != null && !"".equals(dateS)) {
            String dateFormat = "yyyy-MM-dd";
            SimpleDateFormat df = new SimpleDateFormat(dateFormat);
            java.util.Date parsedDate1 = null;
              {
                try {
                    parsedDate1 = df.parse(dateS);
                } catch (ParseException e) {
                    // TODO
                }
                sqlStartDate = new java.sql.Date(parsedDate1.getTime());

            }
        }
        return sqlStartDate;
    }



Following scrip tis used to convert String into  oracle.jbo.domain.Date

        private Date stringToDate(String dateS)
          {
         Date date=null;
           
          if(dateS!=null &&  !"".equals(dateS)   )
           {
           String dateFormat = "dd-MMM-yyyy";
           SimpleDateFormat df = new SimpleDateFormat(dateFormat);
               java.util.Date parsedDate1=null;
       
            try
             {
              parsedDate1 =  df.parse(dateS);
       
             }
             catch(ParseException e)
             {
              e.printStackTrace();
               
             }
             date = new Date(new Timestamp(parsedDate1.getTime()));  
             }
          return date;
          }

The following diagram represents the metadata XML files used for a Fusion web application:

Note : The above is an excerpt from : Jobinesh : Oracle ADF Real World Developer Guide

What happens when you execute an entity-based view object?

ViewObject vo = applicationModule.findViewObject("Departments");

vo.execute();//execute view object to fetch rows

Row row=vo.first();//Move to the first row in the row set

The following sequence diagram highlights how the business components interact

with one another to query the database:

Note : The above content is from : Jobinesh  : Oracle ADF Real World Developer Guide a fantastic book on ADF.

Just shared the above for reference to others.
