Appreciate quick response!!

In EO Impl java, set the file id and other mandatory fields, something like below. You can also search OAF forum for more details.
public void create(AttributeList attributelist)
super.create(attributelist);
try
OADBTransactionImpl oadbtransactionimpl = (OADBTransactionImpl)getOADBTransaction();
String s = "select fnd_lobs_s.nextval from dual";
ViewObject viewobject = oadbtransactionimpl.createViewObjectFromQueryStmt(s);
Number number;
Row row;
for(number = null; viewobject.hasNext(); number = (Number)row.getAttribute(0))
row = viewobject.next();
if(number != null)
setFileId(number);
setFileFormat("text");
setUploadDate(oadbtransactionimpl.getCurrentDBDate());
} else
throw new OAException("AK", "AK_CANNOT_GET_FILEID");
viewobject.remove();
catch(Exception exception)
throw new OAException("AK", "AK_FND_LOBS_NOT_CREATED", exception);
