Uploading/downloading a file to database

Question

Hello friends,
I have created a page into which there is a button names "Upload Resume".
The idea is when an HR person clicks this button it should fetch out the resume
from his local machine and it save resume into the database.
My doubts are as follow:-
1. Where does the resume get stored in database or at the unix box
2. What we can do to download the same resume.
Please guide me.
Waiting for your responses.
Regards,
Pankaj Kedia

Hi,
The code that you have referred to me is a lot different than what I currently have. For example in the code it seems like you have the following statements(below) in the Process Request of Controller, But I have it in the AMImpl. Please let me know where these should be.Off course you can have the code in the AM as well.
>
OAApplicationModule ap = pageContext.getApplicationModule(webBean);
OAViewObject vo = (OAViewObject)ap.findViewObject("FndLobsVO");
if (!vo.isPreparedForExecution())
vo.executeQuery();
Row row = vo.createRow();
vo.insertRow(row);
Also I have my BLOB in the same view object as other data(LacEmpExposureVO) which refers to a custom table. I am NOT storing them in the FND_LOBS.
Do I need 2 columns one for storing the "uploaded file name" of type varchar2 and the other of type BLOB for the "uploaded file"
Yes it is the same as in FND_LOBS, i have a column FILE_NAME that contains the name (varchar2) of the uploaded file.
The OAMessageFileUploadBean View Attribute points to the BLOB column, called FILE_DATA (in the case of FND_LOBS).
Either ways it is not working as expected.
I modified the code like this and it is not erroring now, But not saving the file name either. When I display the column on the search page then it is displaying the contents of the BLOB column (UploadDataBlob) taking up the entire page instead of displaying it as a hyper link with the file name.
// get a handle to the uploadbean. the column UploadDataBlob is of type BLOB
OAMessageFileUploadBean uploadBean = (OAMessageFileUploadBean)webBean.findChildRecursive("UploadDataBlob");
// set file name display in the column UploadDataBlobFilename of type varchar2
OADataBoundValueViewObject displayNameBoundValue = new OADataBoundValueViewObject(uploadBean, "UploadDataBlobFilename");
uploadBean.setAttributeValue(DOWNLOAD_FILE_NAME,displayNameBoundValue);
In the code above if I change the following statement:
OADataBoundValueViewObject displayNameBoundValue = new OADataBoundValueViewObject(uploadBean, "UploadDataBlobFilename");
TO
OADataBoundValueViewObject displayNameBoundValue = new OADataBoundValueViewObject(uploadBean, "UploadDataBlob");
I get the following error:
UploadDataBlob - JBO-25009: Cannot create an object of type:oracle.jbo.domain.BlobDomain with value:F1606_ApplicantFlowLog.pdf
You cannot assign the BLOB column this way, because the OADataBoundValueViewObject is only used to get the UploadBean to display the uploaded file name, that is why i assign the FileName.
Why do you want to assign the BLOB column ?
Use this to assign the file name:
// set file name display
OADataBoundValueViewObject displayNameBoundValue = new OADataBoundValueViewObject(uploadBean, "FileName");
uploadBean.setAttributeValue(DOWNLOAD_FILE_NAME,displayNameBoundValue);
And for example this to assign MIME type (if you have this info in your table off course):
// set content type (MIME)
OADataBoundValueViewObject contentBoundValue = new OADataBoundValueViewObject(uploadBean, "FileContentType");
uploadBean.setAttributeValue(FILE_CONTENT_TYPE, contentBoundValue);

Any Help is greatly appreciated..
