In adf,how to delete a file generated on server,when the webpage is closed

Hi,
I have an application consisting of 2 pages. in the 1st page i will give some input details and when i click on submit, some java code is getting executed in the back. That java code generates a csv file in the server location. after succesful execution of java code, i was redirected to 2nd page. In 2nd page, i am giving option to download and when the user clicked on download button and after the file is downloaded -- in the backend i am deleting the file from the server. Till this point everything is fine. But if the user didnt click on the Download button and instead if he closes the browser, the csv file gets remained on the server itself. This is the issue i am facing .. I am not able to get an idea in ADF Framework, how to delete a file when the browser is closed. Please help me out in this.
Thanks in advance !!!

ADF has nothing to do with tracking browser close buttons. What you can do is call a JS function and call the method which deletes the file from within the JS function. ADF has a component for calling java code from JS call.

Hi,
Use open dataset to read file from application server.
try like this sample code:
data : p_file like ibipparms-path.
data : rec(350) type c.
data: g_delimiter(1) type c value ','.
maintain the file path in p_file. then
open dataset p_file for input in text mode encoding default.
   IF SY-SUBRC = 0.
do n times.
READ dataset p_file into rec.
split rec at g_delimiter into your internal table fields like it-id it-name it-age.
append it.
clear it.
enddo.
close dataset p_file.
Now you have the data in internal table it.

How to delete zip file in sftp server

Hi Gurus,
I am having one .zip file with data files inside on the sftp server. Can you please how to delete the .zip files in the sftp server. I am able to delete normal files by using 'rm' on sftp.
And one more request my sftp is prompting for the password everytime, then i need to enter the password manually. Can any one suggest how to write in shell script to accept that.
Thanks in advance.
Regards
Nagendra

You might want to look into user equivalence and configure a certificate for ssh so it does not prompt for a password.
It will also allow you to use sftp without a prompt for a password.
On the server side:
Edit /etc/ssh/sshd_config and remove the # from the following:
RSAAuthentication yes
PubkeyAuthentication yes
AuthorizedKeysFile .ssh/authorized_keys
Then restart the ssh server:
/etc/init.d/sshd restart
Login as the user for whom this is for:
su - <username>
mkdir .ssh
chmod 700 .ssh
On the client side:
Run the following command:
ssh-keygen -t rsa (omit password)
Then use the following to copy the public key from the client to the
corresponding login .ssh directory on the server side;
scp .ssh/id_rsa.pub username@remote_host:.ssh/authorized_keys

Hi ,
The onclick event provides you with a standard paramater "CONTEXT_ELEMENT" which has the element from which the event is triggered.
so you can declare this in the handler(if it is not there) and use it as follows.
CONTEXT_ELEMENT TYPE REF TO IF_WD_CONTEXT_ELEMENT an importing paramater.
DATA:
NODE_MODULE TYPE REF TO IF_WD_CONTEXT_NODE,
ELEM_MODULE TYPE REF TO IF_WD_CONTEXT_ELEMENT,
STRU_MODULE TYPE IF_V_MODULE=>ELEMENT_MODULE .
data itab TYPE TABLE OF zac_modules.
CONTEXT_ELEMENT->GET_STATIC_ATTRIBUTES(
IMPORTING
STATIC_ATTRIBUTES = STRU_MODULE ). "Using the context_element paramater to get the static attributes.
NODE_MODULE->GET_STATIC_ATTRIBUTES_TABLE(
IMPORTING
TABLE = itab )   "getting all the data.
DELETE itab WHERE zmodule_id = STRU_MODULE-zmodule_id. "deleting the particular row from the table and binding it.
CALL METHOD NODE_MODULE->BIND_TABLE
EXPORTING
NEW_ITEMS = itab
* SET_INITIAL_ELEMENTS = ABAP_TRUE

How to attach a file to an email without using JavaMail

hi everyone!
I'm trying to develope a program wich has to send email messages with attached files. Specifications say that I can't use JavaMail. So I'm trying to use SMTP. It's a very simple protocol, but I haven't found how to send attached files.
Any suggestion or source code? Thanx Very much!!!

you will need to add a mime body to the data as done in the example message (i found it somewhere on teh internet so don't blame me for erors in it ;) )
MAIL FROM:<[email protected]>
RCPT TO:<[email protected]>
DATA
Mime-version: 1.0
Content-Type: multipart/mixed; boundary=OpenVMS/MIME.572522828.951855

Content-Type: text/plain; charset=ISO-8859-1

Content-Disposition: inline
We have modified this to send with SFF for SMTP - TCPIP

for info about how to use mime look at the RFC of mime (just do a google search)

How to delete pdf files created on server using cfdocument pdf?

I am using <cfdocument format="pdf" ...
to create a dynamically named and generated .pdf and it works rather well. Navy managers can easily email the pdf to ships in the fleet and planning forces in the shipyards. (Planning data changes almost daily). However I have noticed that the pdf file stays on the server. Over time this could become a problem with numbers. Is there something I am missing to remove these pdfs over time. Other than a manual review and delete. This government server requires 4 logins and your right arm to update, so something auto is needed.

Thanks for responding:
I am not using cfmail - I am leaving it up to the user to print save or email.
Your second option sound good but I really was hoping I was just missing something easy (new to cf).
I did try giving the pdf the same name but I was having lots of troble with always returning the cached version.

How to delete a file from time machine without entering time machine mode ?

Is there a terminial hack or a third-party app to delete a backed up file from the finder and at the same time from time machine without having to enter time machine mode, and is there a shortcut to do so ?

Please post your code using code tags (click on CODE above the text area, when posting)
response.setContentType("application/octet-stream");Why octet-stream? Set the correct mime-type.
String disHeader = "Attachment; Filename=\"filename\"";The filename should just be the file's name. Not the complete path to the file! This will tell anyone where the file is located on the server. It's also inconvenient because by default,the browser will suggest it as the name for the download.
Your way of writing to the output stream is just plain wrong. See this snippet (picked from [http://balusc.blogspot.com/2007/07/fileservlet.html])
        BufferedInputStream input = null;
        BufferedOutputStream output = null;
        try {
            // Open streams.
            input = new BufferedInputStream(new FileInputStream(file), DEFAULT_BUFFER_SIZE);
            output = new BufferedOutputStream(response.getOutputStream(), DEFAULT_BUFFER_SIZE);
            // Write file contents to response.
            byte[] buffer = new byte[DEFAULT_BUFFER_SIZE];
            int length;
            while ((length = input.read(buffer)) > 0) {
                output.write(buffer, 0, length);
            // Finalize task.
            output.flush();
        } finally {
            // Gently close streams.
            close(output);
            close(input);
        }
