how can I Read a text file from DB directly (don’t use PLSQL). ?

If there is a known structure, you could use External Table access and query that "file" as any table.

Reading a text file from a URL

I am having problems trying to read a text file from a URL.
This is the code i have been using:
package Java;
import java.net.*;
import java.io.*;
public class Main_1 {
public static void main(String[] args) throws Exception {
     URL myAddress = new URL("http://www.geocities.com/simonrobinson1/java/farrago.txt");
     BufferedReader in = new BufferedReader(
                    new InputStreamReader(
                    myAddress.openStream()));
     String inputLine;
     while ((inputLine = in.readLine()) != null)
     System.out.println(inputLine);
     in.close();
but it returns an error saying:
java.net.NoRouteToHostException: Operation timed out: no further information
at java.net.PlainSocketImpl.socketConnect(Native Method) .....etc etc.
Is this just a problem due to my network or is there something wrong with my code ????

Altho you can access the file by typing the URL in a browser, geocities being a free web-hosting service don't like you to access the materials without seeing their ads. You have to find a way to trick it into thinking that you are indeed coming in from a web browser even tho you aren't.

Sample code to read a text file from UNIX directory.

I am using 9i Developer Suite, application server is 9.0.4. I want some help on how to read a flat file from UNIX environment. A sample code could be very helpful.
In windows, i use this kind of code:-
I declare an object & then write to a file using these sample staements:-
file_handle text_io.file_type;
filename := 'd:\ran\egs\uninvoiced.txt';
file_handle:=text_io.fopen(filename,'w');
text_io.put_line(file_handle, 'MOBILE NO '||'COUPON NO ' || 'DATE');
I hope, my question is clear. Please help in solving the doubt.
Regards.

filename := 'd:\ran\egs\uninvoiced.txt';This is a Windows directory, so it won't work on Unix.
For the rest of the code: see examples in the Forms Builder Online Help.

Reading a text-file from within a Jar-file...

I've made a program, that reads from a text-file. And it works great. But when I try to put the program into a jarfile, I get a fileNotFoundException... I have the textfile both inside and outside the jarfile... with the same result.
Does anyone know what I might be doing wrong?
Thanx in advance!
Martin

Depends on the path you enter for the text file. If you simply put "filename.txt" then you should try to have the file in the same directory as the class which accesses the file.

How to read a text file from other machine???

I have a text file located in local machine. I use th e code below to retrieve data from that particular text file.
String realPath = (String)getServletContext().getRealPath("");
BufferedReader holsFile = new BufferedReader(new FileReader(realPath + "/webpages/holidays.txt"));My question is , how could I retrieve the records from the tsxt file if the file is located in another machine or webserver?
Thanks for advanced.

It's ok to be new.
The answer is yes. (But I'll let you look in the javadoc to see which package it's in).
Also it may be worth understanding that there is no such thing as a "function" in java, operations are termed "methods". To go further, you should realise that URL is a class not a "function" or method. The parentheses mean you're calling the constructor.

Reading text file from database server in OA Page

Hi Guys,
I am trying to embed an applet with in an OA Page. The applet is used to mainly for showing Gantt chart. I have to pass my connection details from OA Page to applet, I dont pass directly the connection details to the applet so i am placing all the server details, user name and password in a text file on the database server.
So from the OA Page i have to read the contents of the file on the database server and pass them to the applet using the <PARAM> tag. My question is how to read the text file from the database server.Any Inputs?
Thanks in advance for your help.
Regards,
Nagesh Manda.

If the file to be read is on the database, then it makes sense to use the pl/sql code to read the file. Make a call to this pl/sql code from page controller to get back the values.

How to download a text file from the server

hi everyone,
can anyone tell me how to download and read a text file from the server and saved in into resource folder.
with regards
pallavi

its really easy
To read from server, use something like:
HttpConnection connector = null;
InputStream inp_stream = null;
OutputStream out_stream = null;
void CloseConnection()
     if(inp_stream!=null)inp_stream.close();
     inp_stream=null;
     if(out_stream!=null)out_stream.close();
     out_stream=null;
     connector.close();
     connector = null;
public void getResponse(String URL,String params)
try
     if(connector==null)connector = (HttpConnection)Connector.open(URL);//URL of your text file / php script
     connector.setRequestMethod(HttpConnection.POST);
     connector.setRequestProperty("User-Agent","Profile/MIDP-2.0 Configuration/CLDC-1.1");
     connector.setRequestProperty("content-type", "application/x-www-form-urlencoded");
     //connector.setRequestProperty("charset","windows-1251");
     //*** If you need to send ("arg1=value&arg2=value") arguments to script use this:
     out_stream = connector.openOutputStream();
     byte postmsg[] = params.getBytes();
     out_stream.write(postmsg);
     int rc = connector.getResponseCode();//in any case here connection will be opened & closed
     if (rc != HttpConnection.HTTP_OK)
          CloseConnection();
          throw new IOException("HTTP response code: " + rc);
     inp_stream = connector.openInputStream();
     int pack_len = inp_stream.available();
     byte answ[]=new byte[pack_len];
     inp_stream.read(answ);
     CloseConnection();
     ProcAnswer(answ);//process received data
catch(Exception ex)
     System.err.println("ERROR IN getResponse(): "+ex);
} And you can read from resource file like
public void loadFile(String filename)
    DataInputStream dis = new DataInputStream(getClass().getResourceAsStream("/"+filename));
    String str="";
    try
         while (true)
            ch = dis.read();//read character
            if(ch=='\r')continue;//if file made in windows
            if(ch=='\n' || ch==-1)//end of line or end of file
                if(str.length()==0)continue;//if empty line
                //do some thing with "str"
                if(ch==-1)break;//it was last line
                str="";//next line
                continue;
             str+=(char)ch;
       dis.close();
   catch (Exception e)
       System.err.println("ERROR in loadFile() " + e);
}Welcome! =)

Reading a Text file in Procedure

Hello,
How do I read a Text file in reverse direction in PL/SQL Procedure. Every time I want to read last line in the file.
Can I read last line without going through whole file?
Thanks
Sameer

use utl_file.fopen() in read mode
and then use utl_file.get_line()
you cannot directly read the last line in a file. you have to achive this programtically.

How to upload a text file from a shared folder and provide an o/p

how to upload a text file from a shared folder and provide an o/p containing the details in each order in the text file

Hi,
Use GUI_UPLOAD to upload a text file from a shared folder.
Use GUI_DOWNLOAD to download data in a file on the presentation server or use OPEN DATASET, TRANSFER and CLOSE DATASET statements to download data to the application server.
Now, I hope the code for data fetching, if required, is already present in the report.
Reward points if the answer is helpful.

Reading and writing to a text file from an Applet

I'm a novice java programming with very little formal programming training. I've pieced together enough knowledge to do what I've wanted to do so far...
However, I've been unable to figure out how to read and write to a text file from an Applet (I can do it from a normal java program just fine). Here is a simple example of what I'd like to do (you can also look at it on my website: www.stat.colostate.edu/~leach/test02/test02.html). I know that there is some problem with permission/security but I'm not smart enough to understand what the error messages are telling or understand the few books I have. If anyone can tell me how to get this applet to work, or direct me to some referrences that would help me out I'd really appreciate it.
Thanks,
Andy
import java.applet.Applet;
import java.net.*;
import java.awt.*;
import java.awt.event.*;
import java.util.*;
import java.io.*;
public class test02 extends Applet {
public Button B_go;
public GridBagConstraints c;
public void init() {
this.setLayout(new GridBagLayout());
c = new GridBagConstraints();
c.fill = GridBagConstraints.BOTH;
B_go = new Button("GO");
c.gridx=1; c.gridy=0; c.gridwidth=1; c.gridheight=1;
c.weightx = c.weighty = 0.0;
B_go.addActionListener(new ActionListener() {
public void actionPerformed(ActionEvent e) {
setCursor(Cursor.getPredefinedCursor(Cursor.WAIT_CURSOR));
print_stuff();
setCursor(Cursor.getPredefinedCursor(Cursor.DEFAULT_CURSOR));
this.add(B_go,c);
public static void print_stuff() {
try{
File f = new File("test02.txt");
PrintWriter out = new PrintWriter(new FileWriter(f));
out.print("This is test02.txt");
out.close();
}catch(IOException e){**/}
}

I have almost the exact same problem, and I am in the same situation as you are with respects to the language.
I am simply trying to create a file and output some garbage to it but my applet always spits back a security violation. I've tried eliminating the restrictions on the applet runner I use but I still get the error.
My method:
debug = new Label() ;
debug.setLocation( 20, 20 ) ;
debug.setSize( 500, 15 ) ;
add( debug ) ;
// output
try
     OutputStream file = new FileOutputStream( new File( "" + getCodeBase() + "output.txt" ) ) ;
     byte[] buffer = { 1, 2, 3, 4, 5 } ;
     file.write( buffer ) ;
     file.close() ;
} catch( Exception e )
     debug.setText( e.toString() ) ;
     Can anyone tell why this isnt working?

From an Oracle form, I want to read a text file.

From an Oracle form, I want to read a text file. In the form on a button press I have:
declare
in_file Text_IO.File_Type;
linebuf VARCHAR2(1800);
filename VARCHAR2(30);
BEGIN
filename:=GET_FILE_NAME('U:\ora_devl\pps\work\a.txt', File_Filter=>'Text Files (*.txt)|*.txt|');
in_file := Text_IO.Fopen(filename, 'r');
LOOP
Text_IO.Get_Line(in_file, linebuf);
-- :text_item5:=:text_item5||linebuf||chr(10);
Text_IO.New_Line;
END LOOP;
EXCEPTION
WHEN no_data_found THEN
Text_IO.Put_Line('Closing the file...');
Text_IO.Fclose(in_file);
END;
It gets an ORA-302000. I suspect the problem starts with the GET_FILE_NAME because when I comment out everything but that, It processes endlessly never ending.

What can you tell me? Thanks

GET_FILE_NAME will try to open an "Open File" dialog on the server, which obviously can't happen. If you want to use that type of behavior you need to use WebUtil and the function CLIENT_GET_FILE_NAME. Example:
filename := CLIENT_GET_FILE_NAME('C:\', File_Filter=> 'Text Files (*.txt)|*.txt|All Files (*.*)|*.*|', dialog_type=> OPEN_FILE);Refer to the Builder Online help for more details. You can also refer to the demo which is available here:
http://www.oracle.com/technetwork/developer-tools/forms/downloads/index.html
More information here:
http://www.oracle.com/technetwork/developer-tools/forms/webutil-090641.html
Also, it appears that you are attempting to use a mapped drive ("U"). Although this can be made to work, it is not recommended and in some cases will not be supported. If you need access to remote files, you should use some other mechanism to bring the file to the local machine before manipulating it.
