Appending to beginning of file..

Appending to beginning of file..
I�m trying to append data to the beginning of a text file rather than at the end..
* Example the text files content, before appending the data..
1. old data A
2. old data B
3. old data C
* After appending �New Data� to the top of this file..
1. New Data
2. old data A
3. old data B
4. old data C
Notes:
1) If i use �FileWriter(txtfile, true)�, it will write to the end of the file, not the beginning, so is not useful, and �FileWriter(txtfile)� will wipe the old data, again not what I wont,..
2) The file is way too big (+10000lines), there�s got to be an easier way then writing the contents to another file just to add one or two more lines to the top every now and again..
3) yep I have to have the data at the top of the file, is there an easy way to do this that is not resource intensive and process consuming for large files. thanks

Actually... can't you use a RandomAccessFile object
and sent the pointer to the beginning of them
document? If not you could always right your new
data to a completely new file then append the old
file to the new one. I am almost positive that the
first idea should work though.I am almost positive that you are wrong. You can point the beginning of a RandomAccessFile but when you write bytes starting at zero it doesn't magically push everything else back it just over-writes what is there.
What was stated is correct. You CANNOT append to the beginning of a file as desired here no matter what you do.

Why cant i append objects to a file

i'm amazed that i cannot append objects to a file
as i did earlier in c++
it gives StreamCorrupt error

Ashutosh.options4u wrote:

(a) ObjectOutputStream writes a header which ObjectInputStream expects to find at the beginning of the stream and nowhere else
(b) closing an ObjectOutputStream and starting a new one to append to the same file breaks the specified semantics for preservation of object graphs under Serialization, which can only be implemented within a single instance of ObjectOutputStream.
it gives StreamCorrupt errorI agree.

How to append records in a file, through file adapter.

Hi All,
How to append records in a file, through file adapter.
I have to read data from database and need to append all records in a file.
Thanks in Advance.

Hi,
I think you have a while loop to hit the DB in your Process (As you said you have to fetch data from DB 10 times if 1000 rec are there)
First sopy your DB O/P to one var
and from second time append to previous data.(Otherwise you can directly use append from starting instead of copy and append)
When loop completes you can transform to File adapter Var.
Otherwise you can configure yourFileadapter such that it will aapend current records to previous records.
You can use 'Append= true' in your file adapter wsdl.
It will append previous records to current records in the same file.

Append data into the file in application server

Hi Friends,
I have an issue where i have a job which has three different stepst for same program. If i run the job the program will create a file in the application server and append the other two steps in the same file without overwriting the file or creating a new file.
My problem is like its creating three different files in application server for that particular job since it has three steps . Its not appending into one particular file .
I am using the FM 'Z_INTERFACE_FILE_WRITE' where i have used the pi_append in the exportng parameter . ITs working when i specify the file in local system. It is appending correctly when i run the report normally to apppend into local system.
But when i schedule a job to append the file in application server its creating three different files.
Kindly help me if anyone is aware of this issue
Thanks in advance
Kishore

Hi,
Please use open dataset to write and append files.Please check the logic of Z FM which you are using .
To open and write into a file use
OPEN DATASET FNAME FOR OUTPUT.
To append data into existing file use
OPEN DATASET FNAME FOR APPENDING.
To write into file:
v_file = file path on application server
OPEN DATASET v_file FOR output.
IF sy-subrc NE 0.
write:/ 'error opening file'.
ELSE.
TRANSFER data TO v_file.
ENDIF.
CLOSE DATASET v_file.
For appending :
OPEN DATASET v_file fOR APPENDING.(file is opened for appending data position is set to the end of the file).
Thanks and Regards,

Can Acrobat Standard append to an existing file when saving? Can Pro?

Hello all,
I'm wondering if Adobe Acrobat Standard has the function to save to an existing file. I don't mean append two PDF's together after they are already created. I mean I already have a PDF document which I need to add lots of additional pages to. So when creating additional PDF's, I want to be able to tell Acrobat to add those files to the end of the document I already have.
PrimoPDF has this feature which would be a real time-saver in my line of business. In that program, you simply choose the same filename when asked to save the document. It then prompts you to overwrite or append-to the existing file. For business reasons, it would be very advantageous to use Acrobat rather than Primo. Does anyone know if Acrobat Standard can do this? If not, does Pro do it? Thanks for your time. I appreciate any feedback I get.
Chris

Never tried that... you might read in the Acrobat Pro User Guide Online

Appending objects in text file and searching.......

I have been trieng to implement simple search operation on the class objects stored in the text file. but when i try to append new objects in the same file and search for the same; java.io.StreamCorruptedException is thrown. wat the problem is, that wen i append to the text file; it stores some header information before the actual object is stored and on the deserialization, this header information is causing the exception. the same header information is stored every time, i append to the file. anybody knws hw to get past it??? my code is as given below:

How to append Objects in a file.

i have the following sample code ,
its not read data properly and throws Stream Corrupted Exception in the appended record. ( at Last statement of try block ).
Thanks,
import java.io.*;
public class IOError {
public static void main(String[] args) {
try {
ObjectOutputStream oos = new ObjectOutputStream(
new FileOutputStream("data.dat"));
oos.writeObject(new String("string 1"));
oos.writeObject(new String("string 2"));
oos.flush();
oos.close();
ObjectInputStream ois = new ObjectInputStream(new FileInputStream("data.dat"));
System.out.println("----- Round 1 Starts ---------");
System.out.println((String) ois.readObject());
System.out.println((String) ois.readObject());
ois.close();
ObjectOutputStream oos2 = new ObjectOutputStream(
new FileOutputStream("data.dat",true)); // Appending Data
oos2.writeObject(new String("string 3"));
oos2.flush();
oos2.close();
ObjectInputStream ois2 = new ObjectInputStream(new FileInputStream("data.dat"));
System.out.println("----- Round 2 Starts ---------");
System.out.println((String) ois2.readObject());
System.out.println((String) ois2.readObject());
System.out.println((String) ois2.readObject()); // Stream Corrupted Exception
catch(Exception e) {
System.out.println(e);

Nasty. When you open an ObjectOutputStream, it will write a few initializing bytes, so if you really want to append objects to a file, then after you read the first two strings, you need to create a new ObjectInputStream that will read those bytes.
You could write an object indicating that now you are done with this ObjectOutputStream, so when you read the file and read this object, you know you have to create a new ObjectInputStream.
oos.writeObject(new String("string 1"));
oos.writeObject(new String("string 2"));
oos.writeObject(null); // null could be used if you know you won't write any other null's in your code.
//... append
oos.writeObject(new String("string 3"));
oos.writeObject(null);
// read:
FileInputStream fis = new FileInputStream("data.dat");
ObjectInputStream ois2 = new ObjectInputStream(fis);
String s;
while ((s = (String)ois2.readObject()) != null) {
System.out.println(s);
ois2 = new ObjectInputStream(fis);
while ((s = (String)ois2.readObject()) != null) {
System.out.println(s);

Append functionality in Outbound File Adapter

Hi all,
I have a question regarding append functionality in outbound file adapter.
When I append files for example I get a XML file with different XML files in one file, but is it also possible to collect and bundle the files and get a same result when u use BPM?
Do I have to add some parameters?
Kind regards,
Kamran Vakili

It is not possible, when you append XML files.
The result XML file is not valid, as you have multiple declarations and root tags.
The append mode for the file adapter should be used only for flat files.

How to not append '.PART' to the file name of the currently downloading file, and just download the file with its normal filename

In Windows, when Firefox (I'm currently using 7.0) downloads a file, it appends ''.PART'' to the file name of the currently downloading file and just renames it to its original file name after it finishes downloading.
I sometimes like to watch a currently downloading video file, so it will be better if Firefox just downloads the file to its actual filename (like what Opera does), so I can easily double click the incompletely downloaded file and watch it with the video player assigned to that file extension, rather than the awkward ''Right click -> Open With -> Choose Default Program'' route with .part files.
Does anyone know how to set Firefox to do this?

It is possible that your anti-virus software is corrupting the downloaded files or otherwise interfering with downloading files by Firefox and prevents Firefox from renaming the .part file.
Try to disable the real-time (live) scanning of files in your anti-virus software temporarily to see if that makes downloading work.
See "Disable virus scanning in Firefox preferences - Windows"

[SOLVED] Bash - append input to multiple files after checking

I have this to append text to multiple files, so far I have this:
#!/bin/bash
for file in $(ls *.example);
do
echo "Append this to my file." >> ${file};
done;
But I don't want to adjust the script each time so I need something more powerfull and interactive:
What I'd like it to do is: - ask me for the input (text to be appended)
- ask me for wich type of file this action needs to be taken (using wildcard(.suffix))
- before appending, check for duplication (if text is present, do not append)
any thoughts?
*edit for layout purpose

thanks for the great input, i'm learning here.
funny bug I have so far, look at this testrun
[18:45:25][plurt@archaism:~/test] :) $ append.sh
this is a list of files in current directory:
1.test 2.test 3.test
text to be appended?:test1
append to what type of file?:test
grep: *.: No such file or directory
[18:45:38][plurt@archaism:~/test] :) $ ls
*. 1.test 2.test 3.test
the program created a *.
[strike]my[/strike] The code so far is this:
#!/bin/bash
echo -n 'this is a list of files in current directory:'
echo -e
ls
echo -n 'text to be appended?:'
read -e textappend
echo -n 'append to what type of file?:'
read -e filetype
for file in *.${FILETYPE}; do

continue
else
echo "${TEXTAPPEND}" >> "${file}"

Cannot append in a object file

I try to write an Object file, for Workers, this class is a bean that encapsulates information like name, phone, etc.
When I write the file it works fine, and it writes all objects ok!!.
But the problems comes when I re-open the file, to append more Workers, and when I try to read the file, a StreamCorruptedException is thrown from the ObjectInputStream.
Could any body tell me why?
Or if it is possible in Java append in an Object file..
Thanks a lot..
Cano

Thanks for your replay but the answer that I was looking for is in the Question of the Week No. 98. And it is because when write object streams, the ObjectOutputStream writes headers of files each time you reopen and append in that file. Thanks again, but I already know, that I need to set append when open the file.
Best Regards
Cano

JButton method use BOF(Begin Of File) and EOF(End Of File) like VB?

hii all friends :)
I use Oracle Jdeveloper 10G to design with JClient Method.
i want design navigation button use JButton(swing) not use JUNavigationBar.
but i don,t understand how can i check last record and fist record like in Visual basic use Method BOF(Begin Of File) and EOF(End Of File)? What method/syntax in java i use it?
Can u(all friend in comunity forum) help and teach me how?..
Befors, thanks alot :)

Thank,s kanad.
I already try it, but method "isBeforeFirst" and "isAfterLast" not found in javax.swing.Jbutton.

Appending an external text file

Hi everyone. I need a little help. I'm trying to append an external text file. I'm able to read it using the "in.readLine()" and "BufferedReader" commands but can't figure how to append it. The reason being is I'm trying to add new information to each new line. For example my ext. text file looks something like this:
Homer Simpson 3489 Evergreen Terrace Springfield
Marge Simpson 3489 Evergreen Terrace Springfield
Bart Simpson 3489 Evergreen Terrace Springfield
Please note that I'm not using a string tokenizer to read the text file. If someone could please give me an example to append information to each new line I would greatly appreciate it. Also please note that the text file is being read into a vector to hold the information. Thank you.

open the FileWriter or FileOutputStream you use in "append" mode..
http://java.sun.com/j2se/1.4.1/docs/api/java/io/FileOutputStream.html
FileOutputStream(String name, boolean append)
          Creates an output file stream to write to the file
          with the specified name.http://java.sun.com/j2se/1.4.1/docs/api/java/io/FileWriter.html
FileWriter(String fileName, boolean append)
          Constructs a FileWriter object given a file name
          with a boolean indicating whether or not to append
          the data written.

Appending to beginning of file..
