How to upload excel to the database table

Hi,

We create an item type for file Upload and the coding is as under :

Suppose you want to insert the data into table directly from excel so create a EO based VO.

handle the click og Go button in Controller:

OAApplicationModule am = (OAApplicationModule) pageContext.getApplicationModule(webBean);

OAViewObjectImpl vo = (OAViewObjectImpl) am.findViewObject("TempVO1");

if (pageContext.getParameter("Go")!=null)

{

DataObject fileUploadData =(DataObject)pageContext.getNamedDataObject("FileUploadItem");

String fileName = null;

String contentType = null;

Long fileSize = null;

Integer fileType = new Integer(6);

BlobDomain uploadedByteStream = null;

BufferedReader in = null;

try

{

fileName = (String)fileUploadData.selectValue(null, "UPLOAD_FILE_NAME");

contentType =(String)fileUploadData.selectValue(null, "UPLOAD_FILE_MIME_TYPE");

uploadedByteStream = (BlobDomain)fileUploadData.selectValue(null, fileName);

in = new BufferedReader(new InputStreamReader(uploadedByteStream.getBinaryStream()));

fileSize = new Long(uploadedByteStream.getLength());

System.out.println("fileSize : "+fileSize);

}

catch(NullPointerException ex)

{

throw new OAException("Please Select a File to Upload", OAException.ERROR);

}

try

{

//Open the CSV file for reading

String lineReader="";

long t =0;

String[] linetext;

while (((lineReader = in.readLine()) !=null) )

{

//Split the deliminated data and

if (lineReader.trim().length()>0)

{

System.out.println("lineReader : "+lineReader.length());

linetext = lineReader.split(",");

t++;

//Print the current line being

System.out.println(t + " - " +

linetext[0].trim() + " - " + linetext[1].trim() + " - " +

linetext[2].trim() + " - " + linetext[3].trim() + " - " +

linetext[4].trim() + " - " + linetext[5].trim() );

for(Row row = (Row)vo.first(); row!= null;  row = (Row)vo.next())

{

  if(linetext[0].trim().equals(row.getAttribute("EmpId")))

  {

    row.setAttribute("EmpName",linetext[1].trim());

    row.setAttribute("Department",linetext[2].trim());

    row.setAttribute("Designation",linetext[3].trim());

    row.setAttribute("Manager",linetext[4].trim());

    row.setAttribute("Residence",linetext[5].trim());

  }

}

}

}

}

catch (IOException e)

{

  throw new OAException(e.getMessage(),OAException.ERROR);

}

am.getTransaction().commit();

throw new OAException("File Uploaded SuccessFully!!!",OAException.CONFIRMATION);

}

}

How to capture the Go button for the Query region and edit the where cause

Hi,

On query region we can capture the Go button click and execute our own search along with Standard Search.

     OAApplicationModule ap = (OAApplicationModule)pageContext.getApplicationModule(webBean);
    OAQueryBean bean = (OAQueryBean)webBean.findIndexedChildRecursive("queryRN");

    int whereClausecount = 0;
    OAViewObject vo = (OAViewObject)getReprintInvoiceVO1();

How to set system date -1 on a View Attribute

 Hi,
 The following code sets the sysdate-1 on a View Attribute.

             int MILLIS_IN_DAY = 1000 * 60 * 60 * 24;
              Date date = new Date();
              oracle.jbo.domain.Date oracleDate = null;
              try

Steps to add a new Object Attribute to AK Region:---

1) Choose the AK Developer responsibility.


2) Click on “Define Attributes”


3) Now define a new Attribute: IBE_OS_ORDER_HOLDS

4) Save Changes and Click on “Define Regions”:


5) Query for region IBE_ORD_SUM_R


6) Now click on “Object” and then “Object Attributes”.


7) Now add a new Attribute which you defined above and match it with the
Column of the view Here I have matched IBE_OS_ORDER_HOLDS with column ORDER_HOLDS
Of the view: IBE_ORDER_SUM_V

8) Save changes and close the form and then Click on “Region Items” in “Define Regions” form


9) Now add a new Object Attribute IBE_OS_ORDER_HOLDS which we created earlier.


Please make sure Node Display and Queryable Checkboxes are clicked in this.

10) Save Changes and Bounce Apache.


This way new column will be added to ibeCOtdOrdSumMain.jsp.

Thanks,
Gaurav

How to generate XML from Oracle SQL Query

Hi,

PL/SQL package DBMS_XMLGEN creates XML documents from SQL query results. It retrieves an XML document as a CLOB or XMLType value.

Just execute the SQL Statement :

select dbms_xmlgen.getxml('select user_name from fnd_user where rownum < 4') from dual

and in DBMS_OUTPUT you will get the xml data hierarchy and save it as .xml.

How to split rows in Table or Advance Table???

There has been a Requirement given that there is a split icon present against each row in an Advance Table.
As the user clicks on Split Icon...the parent row should get split into two and the new Row should be inserted right below the parent row.

As an OAF Standard New Row gets inserted at the top of the View Rows.

But we can insert it right below the parent row.

Invoke a method in AM as the User press Split Icon and pass the Id of the row to be splitted.
and loop through the VO rows and identify the row to be splitted.
Then set the current row and insert the new row.


for(xxinvoiceVORowImpl row = (xxinvoiceVORowImpl)vo1.first();
row != null;
row = (xxinvoiceVORowImpl)vo1.next())
{
if(row.getAttribute("InvoiceId")!=null)
{
String invoice = (String)row.getAttribute("InvoiceId").toString();
if(inv.equals(invoice))
{
vo1.setCurrentRow(row);
vo1.next();
xxinvoiceVORowImpl newrow = (xxinvoiceVORowImpl)vo1.createRow();
vo1.insertRow(newrow);
break;
}
}
}

This will insert the row right below the Row on which Split icon was clicked.

Thanks,
Gaurav
