Downloading a file with FTP in Java??

Okay, you LIST all the files in the current directory so the client can see them, and when the client wants to GET A certain file, how do you do that in java?????

oh puttytel.exe
or you can just user your command prompt in windows dos... telnet localhost 4444
or whatever, and you connect to a server... There is no client file, just server file where that is doing all the work.

Firefox doesn't reconvert special characters in the file names when download a file with any special characters in the file name

<blockquote>Locking duplicate thread.<br>
Please continue here: [/questions/815207]</blockquote><br>
if i try to download a file with any special characters in file name (e.g. File_Name.pdf), it doesn't reconvert them from the "sanitize url" process and download the file an incorrect name (e.g. File%5FName.pdf).
This is really annoying.
Thank you for your patient

Downloading text file to ftp location

Hi Everyone,
Could you please guide me for the following query:
I am trying to send the output of a sap program in a text file to ftp location. In that, while passing the following parameter the program is allowing me to download the file to ftp location:
CALL FUNCTION 'FTP_CONNECT'
       EXPORTING
         user            = userid
         password        = password
         host            = 'IPADDRESS'
         rfc_destination = 'SAPFTP'
       IMPORTING
         handle          = mi_handle
       EXCEPTIONS
         not_connected   = 1
         OTHERS          = 2.
Through this way i am able to download the file to ftp location(as per ipaddress).
But when trying to download the file in a folder on the same ftp location it is not doing that.
The parameters, which i am passing are described below:
CALL FUNCTION 'FTP_CONNECT'
       EXPORTING
         user            = userid
         password        = password
         host            = 'IPADDRESS/Folder_Name'
         rfc_destination = 'SAPFTP'
       IMPORTING
         handle          = mi_handle
       EXCEPTIONS
         not_connected   = 1
         OTHERS          = 2.
Please guide.
Thanks and Regards

Hi,
While using CONNECT, we do not have to give the folder. It should only be the server / ip address.
While using FTP_COPY, we can give the folder name in parameter FILE_DESTINATION.

HT5701 Cannot download pdf files with Safari 6.0.4?

Cannot download pdf files with Safari 6.0.4

Back up all data.
Triple-click the line of text below to select it, the copy the selected text to the Clipboard (command-C):
/Library/Internet Plug-ins
In the Finder, select
Go ▹ Go to Folder
from the menu bar, or press the key combination shift-command-G. Paste into the text box that opens (command-V), then press return.
From the folder that opens, remove any items that have the letters “PDF” in the name. You may be prompted for your login password. Then quit and relaunch Safari, and test.
The "Silverlight" web plugin distributed by Microsoft can also interfere with PDF display in Safari, so you may need to remove it as well, if it's present.
If you still have the issue, repeat with this line:
~/Library/Internet Plug-ins
If you don’t like the results of this procedure, restore the items from the backup you made before you started. Relaunch Safari again.

Downloading a File with Java

Hi
My application downloads a file from a
website.
The problem I am having is that if no internet connection is present the
program throws an exception to do with "Unable to resolve Inet Address".
If there is an internet connection present it works fine.
The behaviour I would like (and indeed had until I upgraded to WInXp
Pro) is for the application to prompt the user to connect to the
internet if no connection is present.
I have been unable to locate a method in Java that checks whether an
internet connection is present of not.
I am unsure whether the problem is with the setup of the operating
system or with my code, but if Internet Explorer or Outlook are loaded
with no internet connection present then a prompt to connect to the web
is displayed.
Any help would be much appreciated
Thanks

dear friend
u can do like this.
try {
//put your statement here
} catch(<TheException that is thrown>)
System.ot.println("connection to internet is not present");
next part of code
u can also use a finally block if u want that a
statement must be executed.hope u know syntax for that.
regards
sheetal

Can't download a file with : in it

ok, I have a cron job on my server that does a MySQL Dump twice a day. the file output is this ( FileName_01-29-2015_15:53:11.sql.gz) when I try to download it using Dreamweaver it fails:
I can use FileZilla and download it fine so I did some testing and found that the ( : ) in the time is the problem. this i can't change on my server. is there a way to tell DW to download it anyway??

I think the only way you'll be able to get this with DW would be to rename the file first. Might as well use filezilla.

Handling large files with FTP in XI

Hi All,
I have a file scenario where i have to post the file with size of more than 500MB and with the fields upto 700 in each line.
The other scenario worked fine if the file size is below 70MB and less number of fields.
Could anyone help me in handling such scenario with large file size and without splitting the file.
1) From your previous experience did you use any Tools to help with the development of the FTP interfaces?
2) The client looked at ItemField, but is not willing to use it, due to the licensing costs. Did you use any self-made pre-processors?
3) Please let me know the good and bad experiences you had when using the XI File Adapter?
Thanks & Regards,
Raghuram Vedagiri.

500 MB is huge. XI will not be able to handle such a huge payload for sure.
Are you using XI as a mere FTP or are you using Content Conversion with mapping etc?
1. Either use a splitting logic to split the file outside XI ( using Scripts ) and then XI handles these file.
2. or Quick Size your hardware ( Java Heap etc ) to make sure that XI can handle this file ( not recommended though). SAP recommends a size of 5 MBas the optimum size.

Downloading PDF file with a servlet

I'm working on a web application that dynamicaly creates a PDF file and then writes each character to the ServletOutputStream. Ideally, the browser is supposed to recognize the "application/pdf" MIME type and force the file to be downloaded (or opened from current location if the user should choose). When I test it on my local system, the file downloads but it uses the servlet as the file name. On my webserver I get the following problems.
1) On all the browsers I've tested (except Internet Explorer), the output is being printed in ASCII to the display which keeps the file from downloading. Internet Explorer is the only browser that will actually download the file.
2) When it does attempt to download the file, it is creating a file with the servlet as the name as opposed to the filename that I am assigning during creation.
I've been reading all the related posts that I could find in these Forums but haven't been able to find a solution. If anybody has any ideas, I would greatly appreciate your knowledge. Please note that I have set up MIME-mapping for the PDF extension in the WEB.XML file on my web server.
Here is some servlet code that handles the PDF creation and download:
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {
InputStream in = null;
ServletOutputStream out = null;
String dir = "/www/mydirectory/";
try {
// Create the PDF file and retrieve the filename
String filename = PDFCreator.main();
//Flush the response stream and then reset it for writing a PDF to the display
response.reset();
response.setContentType("application/pdf");
response.setHeader("Content-Disposition", "attachment; filename="+filename);
out = response.getOutputStream();
in = new BufferedInputStream( new FileInputStream(dir+filename));
int ch;
while ( (ch = in.read()) != -1 ) {
out.print( (char)ch );
} catch (Exception e) {
e.printStackTrace();
} finally {
if( in != null ) {
in.close();
if( out != null ) {
out.flush();
out.close();

Your code looks correct.
Apparently other people too have been having problems with pdf's. These links may help you solve the problem.

Redirecting may not be a good idea due to url hacking. Streaming the output would be the best way to go.

Opening a binary data file with a local java application from a weblink...

I don't know if this is the right forum for my query, but I would like to be able to click on a data file from a download link on a webpage and be able to have the file "open" into the java application that processes the particular file (as opposed to selecting the "save to disk" option or having the browser display a bunch of funky characters). If the application is not already running, have an instance start up and process the data file and display the information. What steps would I need to take to get this to happen? The application is executed in a windows environment through executing a .bat file and not an executable .jar file. Any thoughts? TIA!

This is entirely a matter of configuring the Windows file associations so that files with that extension are started using your designated process. Depending on the particulars you may be able to establish the association from the context (right-click) menu, or you may need to use Folder Options rom the Control Panel.
In any case, this is a not a Java question, but Windows; if further help is needed you should go to a Windows help site.
