Students unable to use Upload and Manage Files

Our students have been unable to use the _Upload and Manage Files_ function since last week. They receive an *Access Denied* message as soon as they click the link. Here is our debug page:
iTunes U Access Debugging

Analysis
The destination string is valid and the corresponding destination item was found.
The identity string is valid but provides no identity information.
The credential string is valid and contains the following recognized credential:
1. Student@urn:mace:itunesu.com:sites:brockport.edu:classes:200901-1067-DCC-400-61
The time string is valid and corresponds to 2009-01-20 15:24:29Z.
The signature string is valid.
Access
Because the received signature and time were valid, the received identity and credentials were accepted by iTunes U.
In addition, the following 2 credentials were automatically added by iTunes U:
1. All@urn:mace:itunesu.com:sites:brockport.edu
2. Authenticated@urn:mace:itunesu.com:sites:brockport.edu
With these credentials, you have browsing and downloading access to the requested destination.
There is a tab with +Drop Box+ access for Students and I even changed the page access to Shared for Students, but nothing has helped.

Were you ever able to get this resolved? We have the same issue.
Resolved, yes, to a point. After doing some extensive reading, I was able to determine that our fatal assumption was that the podcast media files would be hosted by Apple. According to at least one source, Apple has not offered hosting to new iTunesU accounts since January 2009.
Therefore, the reason we did not have a button for "Upload and Manage Files" is because there was no place for us to upload them to.
I have successfully attached feeds from both MobileMe and Podamatic and we are in the process of setting up our OS X Server with Podcast Producer. We will host the feeds locally and make them available through iTunes U, blogs and other channels.

Our admins don't see "Upload and Manage Files" - even the Primary Admin. Why?

We are setting up our iTunes U site for the first time. NONE of our admins, including the primary admin, can see the "Upload and Manage Files" link in the Tools section, when we are editing a Course page. We can set up Course pages all day long, but we cannot upload content. Obviously this is a show-stopping problem, and so far nobody from Apple has been able to tell us why.
Any suggestions? Thanks in advance,
-- Will

Greetings Will;
Are you and your Administrators using iTunes U Public Site Manager to edit your content or does your tools section look like the attached screen capture?

Internal Server Error when trying to upload and manage files

The instructor was experiencing this difficulty on Tuesday 1/13, after the notice was closed. I just
went into their site again(1/14/09 2:48pm), launched iTunes U and received the same error after clicking on 'Upload And Manage Files' in their iTunes U page.
I was able to reproduce the same error on our iTunes U site.
https://deimos.apple.com/WebObjects/Core.woa/EditFiles/indiana.edu

I have only found two that work correctly. They were created the same way and permissions are the same. I don't know why one works over the other.

Upload and Manage Files missing from Tools area

We are attempting to set up a new iTunes U site but have hit a roadblock when we get to the point of uploading content. All the instructions say to click on the "Upload and Manage Files" link in the Tools section of the iTunes page, but we have no such link:
END EDITING
EDIT ACCESS
iTunes U SUPPORT
LOGOUT
Looking at screenshots from other sites, it looks like it should be between END EDITING and iTunes SUPPORT somewhere. We have only two users registered and we are both Administrators with full edit and upload privileges as far as we can tell.
What are we missing here?

Upload and Manage files - track order not sticking

I uploaded 5 mp3's today, and have been unable to get the tracks to order the way I want to. I move the tracks to the top of the list view, when I click "Done", some of the tracks move all the way up, others stay where they were or just move up one track. Using Safari 3, latest version of iTunes, on a mac.
Anyone else have this happen? Any solutions?
Thanks!
John

Duncan - I tried the move/refresh steps that you suggested, and it worked to a point, but I also started to see some other strange stuff. When I refreshed the browser (Safari 3.2.1) the list would sometimes return to its pre-move state, sometimes would reflect the post-move state, and _sometimes would display a list of files with duplicates of one or more files_. (See image below) Continuing to hit "reload" would fix this but it was inconsistent.
On top of that, I returned to iTunes and refreshed my file list by clicking on another tab, then returning to the Lectures tab. After a couple times doing this, the generated list contained duplicates. The duplicates disappeared after the next refresh. (See image below.)
If for some reason the images don't show up in this post, go to this link: http://picasaweb.google.com/jrussolmu.
Lastly, the problem seems to center around positions 1-5 in the list. I can get it down to where only two files are out of order (1,2,3,5,4) and if I continue to try and move one of the files, it always reverts upon reloading the page, and eventually other files start to move out of order. (And if I click "reload" multiple times without trying to move anything, then the files start to rearrange anyway.)

Upload and Copy files using PLSQL.

Hi All,
Can UTL package can be used to upload any local data file to server?
Or is there any in-built package which can be used to upload files to servers and copy files to another directory?
Thanks in advance.

Uploading and downloading files from a web app (Urgent!!)

Hi everyone:
I'm developing an application in PL/SQL to upload and download files from an HTML webpage. I congured the document table and the parameters necessary in the DAD of my application.
when I upload the file using my webpage that file info is automatically uploaded to the doc table. This is as far as I have gotten.
I need to do the following:
- Place the uploaded file into a column in another table in my database as part of a text message (think of it as an email message), and delete the file from the doc table (as this is thought to be a temp table that holds the file when uploaded from my webpage)
- Retreive the file so that it can be downloaded from another web page.
The file can be a PDF, WORD DOC, etc...
I now that I can do this with InterMedia but I haven't figured out how :(
Can anyone please point me to an example or some documentation that can guide me through the process.
DB VERSION: 8.1.7
IAS VERSION: 1.0.2.2
Thanks,
Carlos Abarca

The idea was for you to look at the code and get an idea of how to access the BLOB in the document table. IF you look at the procedure
insert_new_photo( new_description IN VARCHAR2,
new_location IN VARCHAR,
new_photo IN VARCHAR2 )
It shows how to access the blob that is stored in the document table. You can then copy this blob to your own table using the DBMS_LOB package.
Hope this helps,
Larry

Upload and Download Files in an Application

hi,
I'm use Application Express 2.1.0.00.39 and the procedure " How to Upload and Download Files in an Application" :
http://download-west.oracle.com/docs/html/B16376_01/up_dn_files.htm#sthref177
I do not find the following tables or view:
HTMLDB_APPLICATION_FILES or wwv_flow_file_objects$.
which it is my error?
thanks.
Luigi

The documentation was for version 2.2. I could not find a 2.0 version of this howto:
http://download-west.oracle.com/docs/cd/B31036_01/doc/appdev.22/b28839/up_dn_files.htm#CIHCFCHF
However, I did find the correct name of the view for my version, HTMLDB_APPLICATION_FILES
After following the instructions in the above-mentioned "how to" (uploading and downloading files), I am a getting a html 403 error (You are not authorized to view this page) when I try to download from my custom table using the procedure specified in the howto.
I've granted execute on the procedure to public only (as specified in the doco).
err nvm. This has already been answered,

Uploading and Downloading files in an Applicaiton

I was able to successfully upload and download files stored in the database through Application Express by following the how to instructions at -->
http://download-uk.oracle.com/docs/cd/B31036_01/doc/appdev.22/b28839/up_dn_files.htm#CJAHDJDA
QUESTION: Is it possible to retrieve the downloaded file without granting execute to the download procedure? My DBA is requesting that I remove the procedures public grant, but when I do, I can no longer download the file.

As long as the Oracle username with the connection has 'execute' on the package 'public' should not need execute. Though I do not use the tools in question so there may be factors I am unaware of, but Oracle wise the connected session needs execute. If can get it from public, a role, or a direct grant. I just say use role based grants or direct grants rather than a public grant to get the privilege.

HTML tag to upload and Download files

hello all
IS there any HtTML tag to upload and download files ???
rgds
ASHWIN

Yea, for downloading you can use a normal link. For uploading, you need an html form like
<form name="form1" enctype="multipart/form-data" method="post" action="doSomething.jsp">
<input type="file" name="file">
</form>To be honest I know nothing about jsp and servlets yet, but I would guess that it works just the same as with php, with which I am alot more familiar. Basicly, the form tag with the input type="file" tag tells the form to submit your file to the webserver.
Then, whatever script you call with action="anythingYouWantHere" will handle the file the user submitted. There must be very similar functions to handle them in java than there is in php.
Things to look for with file upload that often are buggy is the permissions / security settings you have on your webserver. Sometimes you need to make a special folder with extra permissions to allow you upload to work.
Thats about all I know on this matter, good luck :)

How can I upload and download files with uiXML?

I want to implement upload and download files with uiXML. In some previouse topic I got answare to look in AbstractPageBroker class in JavaDOC. I did it but this is a very-very little resolution description for this problem. I think for developers YOU (UIX Team) must in very quick time to put some examples on the NET because this is a nice technology but with adecvate samplase and developers guide it will be dead very soon. I digging this forum for information. I see many many people have same problems about this technology. They like it and want to use and try but documentation is very very poor.
WE WANT EXAMPLES and separate forum for UIX. I think it deserve this.
If You have any more detailed documentation would be nice to put on the net. I have uixdemo.zip file but this is in very early fase of development. I downloaded it before fwe months. And now I can't find it anymore on youre site. What happend?

Attila -
I went back and re-read the JavaDoc for AbstractPageBroker and MultipartFormItem and put together the following sample PageBroker based on the description from the JavaDoc:
import java.io.File;
import java.io.FileOutputStream;
import java.io.IOException;
import javax.servlet.ServletConfig;
import javax.servlet.ServletContext;
import oracle.cabo.servlet.BajaContext;
import oracle.cabo.servlet.Page;
import oracle.cabo.share.util.MultipartFormItem;
import oracle.cabo.servlet.xml.UIXPageBroker;
* An extension of UIXPageBroker which stores all uploaded
* files in the temporary directory.
public class UploadingPageBroker extends UIXPageBroker
* Override of AbstractPageBroker.doUploadFile() which saves
* all files to the temporary directory.
protected String doUploadFile(
BajaContext context,
Page page,
MultipartFormItem item) throws IOException
// Get the location of the file to create in the temp directory.
// Of course a real application probably wouldn't upload files to
// the temp directory - just using this contrived example to
// demonstrate basic uploading support.
File file = _getFile(context, item);
if (file != null)
// Create a FileOutputStream. Of course, a real application would
// probably want to buffer the output
FileOutputStream out = new FileOutputStream(file);
// Write out the file
item.writeFile(out);
// Close up the output stream
out.close();
// We can return a value here to add to the PageEvent
// if so desired.
return null;
// Gets the File for the item that we are uploading
private File _getFile(
BajaContext context,
MultipartFormItem item
// Get the file name
String name = item.getFilename();
// If we don't have a file, bail...
if (name == null)
return null;
// Get the path to the temporary directory
File dir = _getTempDir();
// Return the File object
return new File(dir, name);
// Returns the path to the temprary directory
private File _getTempDir()
// Get the temporary directory from the ServletContext
ServletConfig sConfig = getServlet().getServletConfig();
ServletContext sContext = sConfig.getServletContext();
return (File)sContext.getAttribute("javax.servlet.context.tempdir");
In this sample, each uploaded file is simply saved in the temporary directory. You'll want to replace the code that creates the FileOutputStream for the uploaded file to use whatever OutputStream makes sense for your application.
BTW - I used the following UIX page to test this out:
<?xml version="1.0" encoding="UTF-8"?>
<page xmlns="http://xmlns.oracle.com/uix/controller">
<content>
<pageLayout xmlns="http://xmlns.oracle.com/uix/ui">
<contents>
<form name="uploadForm" usesUpload="true">
<contents>
<fileUpload name="uploadedFile"/>
<submitButton name="upload" text="Upload"/>
</contents>
</form>
</contents>
</pageLayout>
</content>
</page>
Hope this sample helps with the uploading part of your question. I'll see if I can provide a download sample in a later post.

About "Upload and download files from ADF into blob type colum."

hi
Using JDeveloper 10.1.3.3.0 I have tried the example available for download from this blog post by Jakub Pawlowski:
"Upload and download files from ADF into blob type colum."
at http://kuba.zilp.pl/?id=1
First a thank you to Jakub for this interesting example.
I have a question about a PDF file that I uploaded using the example.
The file has a size of 10445518 bytes.
After I upload that file, the blob column has a value with a size of 10445516 bytes, 2 bytes less.
SQL> select file_name, dbms_lob.getlength(stored_file) from blob_table;
FILE_NAME
DBMS_LOB.GETLENGTH(STORED_FILE)
ADF-DeveloperGuide-4GL-B25947_01.pdf
                       10445516If I download that file using the example, it has the same size as the blob value, 10445516 bytes.
If I open the downloaded file, using Adobe Reader 8.1.1, it first shows this message:
"The file is damaged but is being repaired."
After that, there is not problem using the PDF file in Adobe Reader.
I have tried this with both Internet Explorer 6 and Firefox 2.0.0.11.
I have also tried this with other (smaller) files, and those upload and download correctly.
question:
Why are those 2 bytes lost during upload?
many thanks
Jan Vervecken

Hi!
I can only post you my code that works for me and as I said I had same problems but can't remember what solved them. My code:
public void fileUploaded(ValueChangeEvent event)
    FacesContext fc = FacesContext.getCurrentInstance();
    UploadedFile file = (UploadedFile) event.getNewValue();
    if (file != null && file.getLength() > 0)
      // here I have some messages written and a call to the method on AM to save the uploaded file to the DB
private BlobDomain newBlobDomainForInputStream(InputStream in)
    throws SQLException, IOException
    BlobDomain loBlob = new BlobDomain();
    OutputStream out = loBlob.getBinaryOutputStream();
    writeInputStreamToWriter(in, out);
    in.close();
    out.close();
    return loBlob;
private static void writeInputStreamToWriter(InputStream in,
                                               OutputStream out)
    throws IOException
    byte[] buffer = new byte[8192];
    int charsRead = 0;
    while ((charsRead = in.read(buffer, 0, 8192)) != -1)
      out.write(buffer, 0, charsRead);
   * Launch the upload - see fileUploaded() for actual upload handling.
   * @return null navigation event - we stay on this page
public String UploadButton_action()
    if (this.getMyInputFile().getValue() == null)
      FacesContext context = FacesContext.getCurrentInstance();
      FacesMessage message =
        new FacesMessage(FacesMessage.SEVERITY_WARN, JSFUtils.getStringFromBundle("fileupload.emptyfielderror"),
                         null);
      context.addMessage(this.getMyInputFile().getId(), message);
    return null;
   * Setter for inputFile UI Component.
   * @param inputFile inputFile UI component
public void setMyInputFile(CoreInputFile inputFile)
    this.myInputFile = inputFile;
   * Getter for inputFile UI Component.
   * @return inputFile UI component
public CoreInputFile getMyInputFile()
    return myInputFile;
}fileUploaded is a valueChangeListener on inputFile and UploadButton_action is as the name says the action for upload button.
Hope this helps. If not, than your problem is probably not the same as mine was, although the message about file corrupted was the same.
Next thing you can check in this case is if your file exceeds max file upload size. I don't know the exact default value, but if the file is too long I think this upload logic will upload only a part of the file and save it to the DB which can also lead to the same file corrupted error.
You can set the max upload value in web.xml 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>15360000</param-value>
</context-param>

Acrobat 9 - we are unable to merge word and excel files into
a pdf. Any advice?

To be expected if you are working in a contemporary OS and contemporary MS Office suite.
The Acrobat 9.x product family passed into End of Support mid-year of 2013.
The product isn't compatible with contemporary OSs or Office suite.
You may have to step up into the Acrobat XI product family.
