Hi Sandeep,
Please find my controller code below:-
public void processFormRequest(OAPageContext pageContext, OAWebBean webBean)
super.processFormRequest(pageContext, webBean);
OAApplicationModule am = (OAApplicationModule) pageContext.getApplicationModule(webBean);
// String fileName = null;
// DataObject fileUploadData =(DataObject)pageContext.getNamedDataObject("ssofileupload");
// fileName = (String)fileUploadData.selectValue(null, "sso.csv");
// System.out.println("Filename"+fileName);
if("display".equals(pageContext.getParameter(EVENT_PARAM)))
System.out.println("Inside display");
DataObject fileUploadData =(DataObject)pageContext.getNamedDataObject("ssofileupload");
String fileName = null;
String contentType = null;
Long fileSize = null;
Integer fileType = new Integer(6);
BlobDomain uploadedByteStream = null;
BufferedReader in = null;
try
System.out.println("Inside try");
fileName = (String)fileUploadData.selectValue(null, "sso.csv");
System.out.println("Filename"+fileName);
// contentType =(String)fileUploadData.selectValue(null, "UPLOAD_FILE_MIME_TYPE");
uploadedByteStream = (BlobDomain)fileUploadData.selectValue(null, fileName);
System.out.println("After uploadedByteStream ");
in = new BufferedReader(new InputStreamReader(uploadedByteStream.getBinaryStream()));
System.out.println("After BufferedReader ");
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
String lineReader="";
long t =0;
String[] linetext;
while (((lineReader = in.readLine()) !=null) )
if (lineReader.trim().length()>0)
System.out.println("lineReader"+lineReader.length());
linetext = lineReader.split(",");
t++;
System.out.println(t + " - " +
linetext[0].trim() + " - " + linetext[1].trim() + " - " +
linetext[2].trim() + " - " + linetext[3].trim() + " - " +
linetext[4].trim() + " - " + linetext[5].trim() );
catch (IOException e)
throw new OAException(e.getMessage(),OAException.ERROR);
