Hi Lakshman,
1.Files in application server are called 'Sequential files'. they are also called as 'Dataset'.
2.To handle sequential file we can follow the below said procedures.
   a. To open sequentioal file:
          OPEN DATASET <FILENAME> FOR { OUTPUT/INPUT/APPENDING}
          IN {TEXT MODE/BINARY MODE}
   b. To process ( reading/writing):
       TRANSFER <FIELD> TO <FILE NAME>,
       READ DATASET <FILENAME> INTO <FIELD>.
c. To close:
        CLOSE DATASET <FILENAME>
3. To see the application files tcode: AL11
4. Download the files from application server to presentation server : CG3Y
5. Presentation server to application server : CG3Z

Reading text file to JEditorPane

Hi,
I'm trying to read text file to JEditorPane and it works but first line is always missing. Here is the code for reading:
try {
   in = new BufferedReader(new FileReader(filePathIn));
   while ((lineIn = in.readLine()) != null) {
        editorPane.read(in, new Object());
} catch (IOException ie)...Any suggestions?

in.readLine is changing the input stream position.
Do this instead:
FileInputStream in = new FileInputStream(filePathIn);
while (in.available() != 0)
    editorPane.read(in, new Object());

String line = reader.readLine();

How can I read text files from LAN if I only know the hostname?

I'm new in Java Developing, and dont know the written classes yet. I need help, how to do the following steps?
<p>1. How can I read text files from LAN if I only know the hostname, or IP address?
<p>2. How to read lines from text files without read all lines from the beginning of file, just seek to a position.
(ex. how can I read the 120th line?)
<p>Please help!
<p>sorry for the bad english

I'm new in Java Developing, and dont know the written classes yet. I need help, how to do the following steps?
1. How can I read text files from LAN if I only know the hostname, or IP address?You need to know the URL of the file. You need to know the hostname, port, protocl and relative path.
The hostname is server, not file.
2. How to read lines from text files without read all lines from the beginning of file, just seek to a position.Use the seek() to get to a random byte.
(ex. how can I read the 120th line?)The only way to find the 120th line is to read the first 120 lines. You can use other file formats to find the 120th line without reading the whole file but to need to be able to detremine where the 120th line is

dear all,
Need to read text file content and have to display it in multiline text box.

TEXT_IO.GET_LINE (in_file,linebuf);
:block2.t1 := chr(10)||:block2.t1||chr(10)||linebuf;

Can I save and read text files on a server that I host?

Hello everyone,
I am a java hobbiest. I was wondering if I set up my own server, running out of my house, could I have my applets save to my computer and read from my computer without having to learn JDBC and a DATABASE language. In other words could i just have my applet save and read text files from and to my server?
I'm trying to set up a sight for my 5th grade class where parents can log into. Thanks for your time.
Oh yeah, which is easier, learning how to set up a server or learning JDBC and a DATABASE language?
If you have any other good idease please tell me them
Thank you, Bryan

Short answer: This isn't gonna work
Long answer: For this to work, the first thing you're going to need is a static IP address and a DNS name registered -actually you don't necessarily need #2 but you're probably gonna want it and it's by far the easier of the steps.
As far as I know to get a fixed IP address you've either gotta be directly attached to a larger network (ie university network) or get a leased line from an ISP.
Once you've got that done come back to us.

Function module to read XML file in ABAP

Hey guys
is there any function module which can read an XML file into an ABAP code?
we are getting some file on the application server in XML format and we need to read this file in ABAP code,how can i achieve this ?
thanz

Hi Ahmad,
These are few functions to work with XML in ABAP.
SDIXML_DATA_TO_DOM: Convert SAP data (elementary/structured/table types) into DOM (XML)
SDIXML_DOM_TO_XML: Convert DOM (XML) into string of bytes that can be downloaded to PC or application server
SDIXML_DOM_TO_SCREEN: Display DOM (XML)
SDIXML_DOM_TO_DATA
Example of using these:
eport z.
data: it_table like t001 occurs 0.
data: l_dom      TYPE REF TO IF_IXML_ELEMENT,
      m_document TYPE REF TO IF_IXML_DOCUMENT,

How to create and read text file using LabVIEW 7.1 PDA module?

How to create and read text file using LabVIEW 7.1 PDA module? I can not create a text file and read it.
I attach my code here.

File_IO.vi ‏82 KB

Well my acquisition code runs perfect. The problem is reading it. I can't seem to read my data no matter what I do. My data gets saved as a string using the array to string vi but I've read that the string to array vi (which I need to convert back to array to read my data) does not work on the pda. I'm using version 8.0. So I was trying to modify the program posted in this discussion so that it would save data from my DAQ. I did that but I still can't read the data after its saved. I really don't know what else to do. All I need to do is read the data on the pda itself. I can't understand why I'm having such a hard time doing that. I found a possible solution on another discussion that talks about parsing the strings because of the bug in the "string to array" vi. However, that lead me to another problem because for some reason, the array indicators or graphs don't function on the pda. When i build the program to the pda or emulator, the array indicators are faded out on the front panel as if the function is not valid. Does this kind of help give a better picture of what I'm trying to do. Simply read data back. Thanks.

To read text file using utl_file

I would like to read test_file_out.txt which is in c:\temp folder.
create or replace create or replace directory dir_temp as 'c:\temp';
grant read, write on directory dir_temp to system;
then when i execute the below code i get the error .
// to read text file using utl_file
DECLARE
FileIn UTL_FILE.FILE_TYPE;
v_sql VARCHAR2 (1000);
BEGIN
FileIn := UTL_FILE.FOPEN ('DIR_TEMP', 'test_file_out.txt', 'R');
UTL_FILE.PUT_LINE (FileIn, v_sql);
dbms_output.put_line(v_sql);
UTL_FILE.FCLOSE (FileIn);
END;
ERROR:
invalid file operation
i would like to use ult_file only and also can you let me know to read the text file and place its contents in tmp_emp table?

Are you trying to read the contents of the file into the local variable? Or write the contents of the local variable to the file?
Your text talks about reading the file. And you open the file in read mode. But then you call the UTL_FILE.PUT_LINE method which, as SomeoneElse points out, attempts to write data to the file. Since the file is open in read-only mode, you cannot write to the file.
If the goal is really to read from the file, replace the UTL_FILE.PUT_LINE calls with UTL_FILE.GET_LINE. If the goal is really to write to the file, you'll need to open the file in write mode ('W' rather than 'R' in the FOPEN call).

How to read text file efficiently?

I use CharBuffer to read text file:
private List<String> load() throws IOException {
        final String B = "<BODY>";
        final String E = "</BODY>";
        List<String> docs = new ArrayList<String>();
        for (File file : files) {
            FileReader reader = new FileReader(file);
            CharBuffer buffer = CharBuffer.allocate(BSIZE);
            StringBuilder sb = new StringBuilder();
            while (reader.read(buffer) != -1) {
                char[] dst = new char[buffer.length()];
                buffer.get(dst);
                sb.append(dst);
                buffer.clear();
            String s = sb.toString();
            System.out.println(file + ": " + s.length());
            int start = 0;
            int i, j;
            while ((i = s.indexOf(B, start)) != -1) {
                j = s.indexOf(E, i + B.length());
                docs.add(s.substring(i + B.length(), j));
                start = j + E.length();
                //System.out.printf("%d %d %d%n", i, j, start);
        return docs;
    }The file size is 1324350, but the code say it is 772802.
What's wrong with this code?
I want to read text file as quickly as possible.
Is this code the right way to read file?
Should I use FileReader or nio Channel and ByteBuffer?
Any suggestions are welcome!

You are reading the file as if it were encoded in UTF-16. Each character uses two bytes so you have half the number of characters as you had bytes.
The following code reads an entire file in one hit.
    public static String readText(File file) throws IOException {
        byte[] bytes = new byte[(int) file.length()];
        DataInputStream dis = new DataInputStream(new FileInputStream(file));
        try {
            dis.readFully(bytes);
        } finally {
            dis.close();
        return new String(bytes, "UTF-8"); // or whatever your file encoding is.
    }But you can still have less characters than bytes if there are any non ASCII-7 characters.
