Download generated file

I'm trying to create a portlet that will allow a user to download a binary file generated by the portlet or stored in the database. My big question is HOW?
What I've come up with so far is I would need to generate a link to a servlet that would set the appropriate content type and send the binary data. How can I generate a URL to a servlet that is still the portal but that has complete control of the content being sent via the connection. I don't want to generate a link to an external servlet because the data is sensitive so making sure the user is authenticated in the portal is a must.
Has anyone created a portlet that can do something like this or can anyone give me some suggestions on how to do it?

Yes there is..
What you can do is you can write a function module (or check if one is available in the google) to check the directory where you are producing the file and create a sequencial file format.
The function module can read the current files in the directory and automatically add 1 to the sequence number part of the file...
For example you can have
CONTROL_RECIPE_DOWNLOAD_000000001.xml
for the first file and the second files is named as
CONTROL_RECIPE_DOWNLOAD_000000002.xml
I am sure this kind of code is available as well in the web.
Thank you,

Changing filename when downloading generated file

The scenario:
There is a list of files that logged in users are able to download. The files themselves are not kept within the web root, as we need to be able to ensure that a user has rights to download the file. To do this I have created a JSP page which (a) checks that the user is logged and has appropriate permissions, (b) sets the content type to something the browser does not understand (to ensure the file, which is basically just text is downloaded instead of just displayed in the browser) and (c) gets and includes the content of the file using java.io.File.
The problem:
... with this approach is that it uses a link which looks something like thefile.snd. This means that the file name in the save dialogue always defaults to 'getfile.jsp', when it needs to default to 'thefile.snd'.
Any ideas? I've considered using an signed applet to do the download and rename the file but would like to avoid this if possible (although if anyone has the source for such an applet that would also be helpful).

Thanks for the post clem. FYI, I had a similar problem but my data was coming from a database - not a file on disk. At first, setting the content-disposition wasn't working. Then I removed the "file; " part and left just
response.setHeader("Content-Disposition","filename="+filename);
and it worked.

Downloading Captivate generated files

Hello,
My organization would like to make our training content
available to users for downloading to their local machines. How can
I make this possible, considering our training website publishes
links of the generated htm file instead of the swf? Please note
that we would like the Captivate output to remain as htm (instead
of swf).
Thanks,
MM

You're correct that Captivate files are not intended to be
run offline except via the .EXE option. Even then, the .EXE is
truly standalone and doesn't support any of the results tracking
options found in the Quiz Manager.
The main reason HTML is not good for offline use is that any
HTML file with embedded Javascript and Flash (as is the case with
Captivate-generated files) is typically considered "dangerous" by
both the browser and Flash Player security settings when run
locally. This can lead to some functionality being disabled, so
unless you do a LOT of testing with users, I wouldn't recommend
running HTML files from anywhere but a web server.
That said, Rick's suggestion of using .ZIP is probably your
only good option. Not a great one, but as good as it gets.
It assumes that your users either all have some sort of
Zip-compatible decompression software (like WinZip) or are using
Windows XP SP2, which has crude Zip file support built-in. It also
assumes that they unzip ALL the files into a given directory and
don't try to run the HTML file directly from the Zip, which may or
may not work depending on the method used to open the Zip
file.

When someone other than myself downloads an image from my web album, a dynamically generated file name replaces the original file name. How I can prevent the original file name being replaced during the downloading process?

When someone other than myself downloads an image from my web album, a dynamically generated file name replaces the original file name. How I can prevent the file name being changed during this downloading process?

Hi Glenyse,
Here are my steps.
1. I upload multiple image (jpg) files onto my photo album.
2. I select the "sharing" by email option for this album.
3. I enter the recipient's email address.
4. The recipient receives my message and clicks on the link.
5. The recipient accesses my photo album and clicks on one of the images.
6. The image opens up to its own screen.
7. The recipient selects the "download" and then save file option.
Here is the part I do not understand. For some reason, during this "download" process, the original name which I have given to the file is replaced by different name. So I was hoping that someone knows how to prevent the file name from being changed during the "download and save" process.
Much appreciated if you can help me find a solution to this problem.

How do I stop firefox from pre-downloading a file during a file download prompt?

I use DownThemAll as my download manager for files generally over 10MB, as my internet connection is generally too slow for firefox to download a file larger then this without firefox "finishing" a download before it's complete, corrupting the file. This never happens with DownThemAll.
For some sites, either there is no download link to right click or it starts automatically, launching the download prompt. Firefox's internal download manager automatically starts downloading the file (not visibly, but in the background) before I can choose to use DownThemAll from the prompt instead.
This wastes bandwidth. Even worse, some hosting sites have randomly generated download gates for each session that expire after disconnection or limit you to a single download in a given time frame. This means that I effectively can't use DownThemAll on certain websites because firefox's own download manager steps in and gets in the way.

Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

How to download a file from a custom server location?

Hello experts,
I have the following scenario:
A BAPI creates an .exe file and stores it in a custom folder in the server where the portal (and my WD application) is running. This happens once a day.
What I need to do is create a link or button (doesn't matter) so that users can click on it and download this file.
I already checked the file upload - download tutorial (http://www.sdn.sap.com/irj/scn/go/portal/prtroot/docs/library/uuid/202a850a-58e0-2910-eeb3-bfc3e081257f;jsessionid=%28J2EE3417500%29ID0774236150DB11016171821629714331End?overridelayout=true) however this one considers the file to be downloaded is stored in the src folder of the project, thus it doesn't really help me.
How can I achieve this? Any suggestions and help will be greatly appreciated.
Thanks!

hi Alain,
Use File API to read data from the file. It will return byte array from the file. Set Byte array to the file resouce context attribute.
bind this attribute to the filedownload UI element.
Since you need to read file from the same server where webdynpro application is running, You can give the folder path on the server where the file is located.
try {
               File inputFile =
               new File("C:\\Test\\Test.txt");
               FileInputStream in = new FileInputStream(inputFile);
               byte b[] = new byte[ inputFile.length()];
               in.read(b);
               in.close();
          } catch (FileNotFoundException e1) {
               // TODO Auto-generated catch block
               e1.printStackTrace();
          } catch (IOException e1) {
               // TODO Auto-generated catch block
               e1.printStackTrace();

How to download a file from Oracle UCM using OSB

Hi,
How can I download a file from Oracle UCM and save it on a filesystem using OSB 11.1.1.5.
Thanks

UCM supplies webservice interfaces which let you retrieve the filecontent by soap calls from UCM (http://ucmhost/_dav/cs/idcplg for example). (maybe you should enable some settings on ucm to have this webservice interface getting published).
This services for example has 2 operations getFileByID and getFileByName.
So you can just call these services from within OSB.
After that you need to do some tests if you eitherway need to create a file-transport business-service and call this one from your proxy service or create a messageType proxyservice (binary) which calls this file-transport business service to be able to write fo filesystem.
I think for the OSB book i used a jca file adapter generated in Jdeveloper and used that one to write to filesystem.

How to download a file from a table not in the parsing schema

We have a table in another schema which holds files in a blob column. I can create a form on this table and the file upload works fine. The file browse page item has the source as the blob column and storage type "BLOB column specified in Item Source attribute". The download link generated for the page shows a call to apex_util.get_blob_file and the parameters are correct. However, when you click on the link you get a Page Not Found 404 error. Same error in Apex 4.1.1. The plsql error is:
ORA-20544: Invalid table owner
ORA-06512: at "APEX_040000.WWV_FLOW_DML", line 1628
ORA-06512: at "APEX_040000.HTMLDB_UTIL", line 2244
ORA-06512: at line 31
Is there a way to use apex_util.get_blob_file to download a file when the table is in another schema?

Hi,
I am not sure that the post explains everything as the "Automatic Row Processing" and "Automatic Row Fetch" process work fine on this page and therefore security should not be an issue.
Thanks for the view suggestion, but I am not sure that a view is a good option for us because the parsing schema does not have create view privilege and therefore the view would be difficult to install and maintain. We will problably end up with a custom download file process.

How to download a file from database

Hi,
My flex application contains a form that uploads a file into the server. This file is however saved in the database, and not on the disk. Most of the tutorials in the database explains how to download a file by passing the file's url to the "download" function of the fileReference Object. That dsnt work for me as my file is saved in the database.
How do I download this file from the server ?
For example, in php, we would do smthing like this :
$content = $file_to_download['content'];
$size = $file_to_download['content_size'];
$type = $file_to_download['content_type'];
$name = $file_to_download['filename'];
header("Content-type:$type");
header("Content-length:$size");
header("Content-Disposition:attachment;filename=$name");
header("Content-Description:PHP Generated Data");
echo $content;
When executing this file, it opens up the "download file" dialog box. How do i get the same effect in flex 4 ?

You need the bytes use FileReference.download() and after download you can save
it on disk with FileReference.save(); You also need FP 10 at least I think. Use
the docs they are less error pron than mi memory :).

Downloading a file via JSP

I am trying to write some code which will generate a file and then download the file

FileInputStream stream = new FileInputStream(f);
BufferedInputStream bis = new BufferedInputStream(stream);
BufferedOutputStream bos = new BufferedOutputStream(out1);
byte[] buff = new byte[2048];
int bytesRead;
// Simple read/write loop.
try {
while (-1 != (bytesRead = bis.read(buff, 0, buff.length))) {
bos.write(buff, 0, bytesRead);

The JSP automatically gets an outputstream/writer, and starts writing to the output. In fact thats where the implicit variable "out" comes from.
Couple of things to be aware of:
Every carriage return outside of a <% %> tag in a JSP gets converted directly into the html as out.println("\r\n");
That means the generated servlet has started writing even before you get the outputstream - which is what raises the exception.
There are two ways to stop this
1 - write it in a servlet - its purely code, with no HTML so servlet is better suited.
2 - have no carriage returns outside of JSP tags <% %>. You currently have one - one the very first line. Try it like this:
<%@page import="java.net.*,javax.servlet.http.*,javax.servlet.*,java.io.*" %><%
ServletOutputStream out1 = response.getOutputStream();
%> // and no carriage return at the end eitherThat should do it.
As an aside, if you are going to be generating a text file, then you can use the implicit writer "out" as opposed to the OutputStream.

Download .jnlp file when first time

Hi Everybody,
I am new bee for java web start.
We are having swing application which we want to distribute through Java Web Start. Client can run application through provided web link. we also want to download .jnlp file to the client machine when user clicked the link first time.
I go through different thread for the above problem in this forum, but though not getting clear idea as in our application, we need to generate dynamic .jnlp file. All solution posted for the above problem assuming that .jnlp file exists at some location, but in our case we have to generate it when user clicked it first time. Any body having some idea ?
Our second problem is, can it possible that user will run the swing application only when he click the link provided on the web server ? In our case authentication of user is done in our web application and when user will click the provided link user id and other information will be pass to swing application as parameters through .jnlp file. If that application will available offline user can run it through last downloaded .jnlp file without clicking the link , which will be not allowded. Also we are concern about multi user environment, as we are thinking to dynamic generation of .jnlp file , it may possible that other user running the same application noted .jnlp file version difference and will download the .jnlp file of other user ?
Can any body have any idea, how can we done the above scenario ?
Thanks in advance,
Dimpal

If you upgrade to Java 1.4.2 it will present a dialog asking for desktop
integration the first time you start the application.
Maybe that's what you want?

Generate file on F110

Dear Friends,
Please help how to generate file from the
F110 Automatic Program and f-58 Vendor Payment
we had a requirment to generate file on documents posted on the these transactions generate file and send it to other addon system I will assign full points for your suggession.
Regards
Bharath

HI,
When configuring the payment methods for the country (transaction OBVCU), choose the payment medium program as RFFOM100.
From se38, pls read the documentation for the program, which will give you the various options & the required config too.
You would also need to configure the instructions keys as required.
To generate the DME file, you have to run the automatic payment program with this payment method.
After the payments have been successfully posted, you can go to DME administration and with the help of dme manager download files on your PC.
SAP has determined that the standard print programs for automatic payments will no longer be supported, and will be replaced by transfer structures created by a tool called the DME Engine.
This tool enables the business to create DME output files without ABAP development, and can be attached to a print program and form for the creation of Payment Advices.
Outside of the DME Engine (DMEE), the majority of the configuration takes place within the following IMG menu path:
IMG Path: Financial Accounting -> Accounts Receivable and Accounts Payable -> Business Transactions -> Outgoing Payments -> Automatic Outgoing Payments -> Payment Media -> Make Settings for Payment Media Formats from Payment Medium Workbench
Config
Assign Selection Variants
IMG -> Financial Accounting -> Accounts Receivable and Accounts Payable -> Business Transactions -> Outgoing Payments -> Automatic Outgoing Payments -> Payment Media -> Make Settings for Payment Medium Formats from Payment Medium Workbench -> Create / Assign Selection Variants or transaction
OBPM4..select your format that you are using
Check in FBZP config that all is linked!
Although this is bitty but you need to work through it!
Start with FBZP, create all there than go to DMEE either to create your own format or use the standard ones.. than go to the menu path above and work through from create to assign...
hope this is clear
assign points.
with regards

The Downloaded PDF file does not contain the Signature through BSP pages

HI,
We have an requirement for Distributing the FORM 16 to all Employee's through our Website, where the user will login and download his own FORM 16 ( TDS Certificate)
This FORM 16 ( TDS Certificate ) is generated in SAP ( ECC 6.0 ) in Payroll Module.
To satisfy the above requirement we have done the following steps.
1) First we have modified the standards SAP Sapscript(Layout) to incorporate the Signature of Authorised Payroll Person.
We have done this by uploading the BMP file ( though t-code SE78 ) and then calling this file in the Standards layout which prints the FORM 16 document.
2) WE also Modifed the Dirver program to Download the above document in a .PDF file.
The Program creates the seperate file for each employee and assigns the employee number as a file name to each downloaded file. These all files are downloaded on a Users Machine.
We opened the Downloaded .PDF files, and checked for the Signatures. The Signature were comming perfect as it ws uploaded.
3) We uploaded these all FORM 16 PDF file off all emlpoyee's to a different SERVER ( BW 7.0 ). With the help of BASIS person, using the FTP utility.
4) We wrote a BSP program to download this ulploaded PDF Files.
BUT we are facing a PROBLEM in the DOWNLOADED PDF file.
The Downloaded file does not contain the Signature which is there is the Original file we uploded this server.
All other data in the dowloaded PDF file is Perfect other than the Signature.
When we open the downlaoded PDF file it give's following message on the Signautre page.
" Xobject not found named 00013"
The number of the Object comes different to different files.
We are using Function module 'SCMS_STRING_TO_XSTRING' to Convert string to Xstring
We are using the the " CALL METHOD CL_BSP_UTILITY=>DOWNLOAD" for downloading the PDF file.
Please suggest some solution if you can
Thanks in advnace.
