ADF Faces : UploadedFile missing bytes

Question

hi
Please consider a simple ADF Faces application, in JDeveloper 10.1.3.3.0, with an upload page containing this:
  <f:view>
    <afh:html>
      <afh:head title="uploadedFileIssue">
        <meta http-equiv="Content-Type"
              content="text/html; charset=windows-1252"/>
      </afh:head>
      <afh:body>
        <af:form usesUpload="true">
          <af:panelPage title="uploadedFileIssue">
            <af:panelForm>
              <f:facet name="footer">
                <af:commandButton text="Upload"/>
              </f:facet>
              <af:inputFile label="file to upload"
                            valueChangeListener="#{backing_uploadedFileIssue.onInputFileValueChange}"/>
            </af:panelForm>
          </af:panelPage>
        </af:form>
      </afh:body>
    </afh:html>
  </f:view>The backing bean class looks like this:
package adfuploadedfileissue.view.backing;
import javax.faces.event.ValueChangeEvent;
import oracle.adf.view.faces.model.UploadedFile;
public class UploadedFileIssue
     public void onInputFileValueChange(ValueChangeEvent pValueChangeEvent)
          UploadedFile vUploadedFile = (UploadedFile)pValueChangeEvent.getNewValue();
          System.out.println("UploadedFileIssue.onInputFileValueChange()"
               + " : getFilename() = " + vUploadedFile.getFilename()
               + ", getLength() = " + vUploadedFile.getLength());
}The web.xml file has been configured like this:
    <context-param>
        <param-name>oracle.adf.view.faces.UPLOAD_MAX_MEMORY</param-name>
        <param-value>5120000</param-value>
    </context-param>
    <context-param>
        <param-name>oracle.adf.view.faces.UPLOAD_MAX_DISK_SPACE</param-name>
        <param-value>102400000</param-value>
    </context-param>You can download the complete application here (check README.txt):
http://verveja.footsteps.be/~verveja/files/oracle/ADFUploadedFileIssue-v0.01.zip
If I run this application, and upload some files, I get this output:
UploadedFileIssue.onInputFileValueChange() : getFilename() = ADF-DeveloperGuide-4GL-B25947_01.pdf, getLength() = 10445516
UploadedFileIssue.onInputFileValueChange() : getFilename() = OC4J-ConfigurationAndAdministrationGuide-b28950.pdf, getLength() = 4434458
UploadedFileIssue.onInputFileValueChange() : getFilename() = OC4J-DeploymentGuide-b28951.pdf, getLength() = 3117284
UploadedFileIssue.onInputFileValueChange() : getFilename() = OC4J-DevelopersGuide-b28952.pdf, getLength() = 2420815I have used these files to upload in this application:
"Application Development Framework Developer's Guide for Forms/4GL Developers" (size 10445518 bytes, in UploadedFile 10445516, so 2 bytes missing)
http://download.oracle.com/docs/cd/B32110_01/web.1013/b25947.pdf
"Containers for J2EE Configuration and Administration Guide" (size 4434460 bytes, in UploadedFile 4434458 bytes, so 2 bytes missing)
http://download.oracle.com/docs/cd/B32110_01/web.1013/b28950.pdf
"Containers for J2EE Deployment Guide" (size 3117285 bytes, in UploadedFile 3117284 bytes, so 1 byte missing)
http://download.oracle.com/docs/cd/B32110_01/web.1013/b28951.pdf
"Containers for J2EE Developer's Guide" (size 2420816 bytes, in UploadedFile 2420815 bytes, so 1 byte missing)
http://download.oracle.com/docs/cd/B32110_01/web.1013/b28952.pdf
question:
Why are there bytes missing in the UploadedFile instances?
note:
This issue is narrowed down from the discussion in this forum thread:
" about "Upload and download files from ADF into blob type colum." "
about "Upload and download files from ADF into blob type colum."
many thanks

Thanks for your reply John.
In the Re: ADF Faces file upload: losing bytes on PDF file you refer to, you write "I'm currently guessing something wrong in the DB with Intermedia, but not sure.".
But, using the ADFUploadedFileIssue-v0.01.zip example application I posted in this forum thread, it is clear that something is already wrong in the UploadedFile implementation.
Currently I only have bug 6774514 logged, but no solution yet.
