Read contents of file into outputstream and send through socket

I have a file. Instead of transferring the whole file through socket to the destination, I will read the contents from the file (big or small file size) into outputstream and send them to the destination where the client will receive the data and directly display it....
Can you suggest any efficient way/methods to achieve that?
Thanks.

I don' t understand what you think the difference is between those two techniques, but:
int count;
byte[] buffer = new byte[16384];
while ((count = in.read(buffer)) > 0)
out.write(buffer, 0, count);
out.close();
in.close();

Read contents of file into outputstream

Can anyone suggest that what are the best methods to read contents of a file (better cater to both conditions: big file size and small file size) into outputstream and send through socket...
Thanks.

Thanks for the answer. But I would like to ask the following question:
I have a VB application which generates a file. I have a Java application which read the contents of the file.
is it possible that VB side calls the read() (file) and send() (through socket to destination) methods in Java application once the file is generated? Actually my objective is VB is responsible for generating a file for Java application to read data from and then send the data (not file) to destination....If it is impossible to achieve, any alternative to achieve this?
Thanks

Sender File (FCC) - Content of File into single XML Tag

Hi,
Input file
This is Line1
This is Line2
Expected Sender File adapter FCC into XML
<Document>
.<File>
..<Content> This is line 1 This is line2</content>
.</File>
</Document>
FCC is giving the following output with the below config,
File.fieldNames = Content
File.fieldSeparator = '0x1A' (HexaDecimal rep for EndOfFile)
<Document>
.<File>
..<Content>This is line 1</content>
..<Content>This is line 2</content>
.</File>
</Document>
How can i read the complete file into a single XML tag?
I am aware of other options (AdapterModules or Javamapping). But i want to keep it simple to FileAdapter using FCC or using MessageTransformBean (if possible)
-SM

FCC donse't work here, So i wrote a simple Java map inside Execute method to convert the content to the required format.
public void execute(InputStream in, OutputStream out) throws StreamTransformationException{
StringBuilder sb = new StringBuilder();
       try {
       BufferedReader reader = new BufferedReader(new InputStreamReader(in, "UTF-8"));
       while ((line = reader.readLine()) != null) {
           sb.append(line).append("\r\n");
       } finally {
       in.close();
After i had the input string, i formatted it to get the required output as XML ...
<Document>
.<File>
..<Content> This is line 1 This is line2</content>
.</File>
</Document>

Open and read from text file into a text box for Windows Store

I wish to open and read from a text file into a text box in C# for the Windows Store using VS Express 2012 for Windows 8.
Can anyone point me to sample code and tutorials specifically for Windows Store using C#.
Is it possible to add a Text file in Windows Store. This option only seems to be available in Visual C#.
Thanks

Read an XML file into an ABAP program and manipulate it.

I would like to know if it is possible to do the following in an ABAP program:
1) Read an XML file into an ABAP internal table
2) Call an XSLT transformation on the source file and store the results in an ABAP table.
Is this possible to do? I have used ABAP XSLT in PI, but never in an ABAP program. I see you can use the CALL TRANSFORMATION command, but I have never used it in an ABAP program.
Kind Regards,
Tony.

When I save a CS6 InDesign file as an .idml file InDesign crashes and sends a report to Adobe.

When I save a CS6 InDesign file as an .idml file InDesign crashes and sends a report to Adobe.
When I restart InDesign the .idml file is in the directory as well as a locked InDesign file.
I cannot open the .idml file, instead I get the message:
Cannot open "" file. Adobe InDesign maynot support the file format,
a plug-in that supports the file format may be missing,
or the file may be open in another location.
I can however open an InDesign .idml file that was saved from InDesign CC software.
InDesign CC software is also unable to open the .idml file that I created in CS6.

It seems to be a corrupted IDML file. Does it happen with every file or only with that one.
What is the content of that file? Did you embed images or graphics or did you ink them? Size?
Maybe that this would help you: Re: InDesign 6 is crashing when attempting to open a particular document. All others are opening OK.

Uploading the contents of file into custom table

Hi ,
I have a req where in i want to put the contents of the file into the Z table . I have taken a file upload UI element and in that i have taken 4 attributes as file name f, file type ,file size and file contents and binded this file contents to the data property of the UI element. Now with out explicitly defining the fields i want to put all this content of file into the Z table created for any file created or if i could put the whole text file into that table so that any one could see that file even though its not saved in the desktop for that user.
Can any one help me out?

Yes i am converting it inot the lstring using the same FM which you have given. I have to store the total file but the only doubt is like if its a input field how could i save a file form. Can you please check the code i want to save the total file into the table.

My mac is converting Word and Excel files into Pages and Numbers files when I click to open them (or download and open them) from an email. I do I get this to stop? It's really aggravating.

My mac is converting Word and Excel files into Pages and Numbers files when I click to open them from an email. Downloading them and opening them doesn't help. How do I make this stop? I don't use iLife and don't want to; my clients are using Office and it's easier for me, except when I have to copy and paste everything they send me from an iLife file back to Word and Excel. Help!!! It's like Apple has become Microsoft, forcing us to use their apps.

Do you have Word & Excel installed, if yes, navigate in the finder to an example of each, right click and select 'Get Info' scroll down to 'Open With' and select the appropriate program, check the box that says 'Change All'

Is there a way to save a fillable form (in Reader) as a static (uneditiable) image and send it for signature without the recipient being able to revise the fields at all?

Is there a way to save a fillable form (in Reader) as a static (uneditiable) image and send it for signature without the recipient being able to revise the fields at all? I have designed a number of fillable forms and sent them to our clients as Reader extended pdfs to be filled out and sent back. Now, certain clients want to be able to fill in the fields and save the doc as a pdf that can't be tampered with so that they can send it to their own people for signature to be returned to them hand-signed and scanned via email.
Since the forms have been secured, and my cleints are only using the free Acrobat Reader, how can they save the filled in form as a static pdf to send on for signature? They do not want to have to print, scan and email. Is there an app, plug-in, simple solution to this?
Thank you,
Rumor

The signature WILL work! I've just looked into it more, thank you so much for pointing me in that direction.
I get it now, it locks the form fields in place after my coworker fills them in and signs it (as the very last step).
I wish I would have asked on here a full day ago. Would have saved a lot of headache and Googling.
Thanks again.

Hi Shailendra,
Your requirement is a huge activity with multiple tasks which can be done in multiple ways.
Some basic points:
1. You can read data from your Third party application using
a. Native SQL or
b. a middleware as PI or
c. using connectors based on the platform of the Third party application (VB, .NET, etc.)
2. Data can be sent to portal using
a. Middleware as PI or
b. Creating RFC's
c. BAPI's.
For any specific details, you can check SDN as detailed posts on each of the above is available or can post further.

Here is the How to import in itunes 11. Including the Join tracks option.
http://support.apple.com/kb/PH12278
Also if you have imported them then this article gives a good understanding of how to tag these songs
http://samsoft.org.uk/iTunes/audiobooks.asp
the other option would be to use an App like Audiobook Builder to stitch the tracks together in upto 12 hour long sections and sends to itunes automatically. It is available in the App Store. There are others available, Audiobook binder is free
