Help with utl_file (read/write file from local directory)

Need help reading/writing file on local machine from plsql using 10.2 DB.
I am trying to read/write a file from a local directory(laptop) without success.
I have been able to read/write to the database server directory but can't write to directory on local machine.
The utl_file_dir parm has been set to * and the db restarted but I can't get it to work... Here's the plsql statement.
out_file := UTL_FILE.FOPEN ( 'C:\PLSQL', 'TEST.TXT', 'W' ,32767);
Whenever I run it continues to write to c:\PLSQL dir on the database server. Have looked at the "Directory" object and created MY_DIR = C:\PLSQL but it writes to the db server.
Running 10.2 on a remote windows server, running PLSQL using sql*navigator.
Thanks in advance for your help..

I don't see how you expect the server to be able to see your laptop across the network, hack into it and start writing files. Even if it could, what if there is more than one laptop with a C: drive? How would it know which one to write to?
Is there a shared drive on the server you can access via the laptop?

I have read 118 files (from a directory) each with 2088 data and put them into a 2 D array with 2cols and 246384row, I want to have aeach file on a separate columns with 2088 rows

I have read 118 files from a directory using the list.vi. Each file has 2 cols with 2088rows. Now I have the data in a 2 D array with 2cols and 246384rows (118files * 2088rows). However I want to put each file in the same array but each file in separate columns. then I would have 236 columns (2cols for each of the 118 files) by 2088 rows. thank you very much in advance.

Hiya,
here's a couple of .vi's that might help out. I've taken a minimum manipulation approach by using replace array subset, and I'm not bothering to strip out the 1D array before inserting it. Instead I flip the array of filenames, and from this fill in the end 2-D array from the right, overwriting the column that will eventually become the "X" data values (same for each file) and appear on the right.
The second .vi is a sub.vi I posted elsewhere on the discussion group to get the number of lines in a file. If you're sure that you know the number of data points is always going to be 2088, then replace this sub vi with a constant to speed up the program. (by about 2 seconds!)
I've also updated the .vi to work as a sub.vi if you wa
nt it to, complete with error handling.
Hope this helps.

FTP Adapter to read multiple files from a directory. Not through polling.

Dear Friends,
I would like to know is it possible to configure the FTP adapter in Oracle BPEL 10.1.3.4 to read multiple files (different names, same structure) from a given directory. I do not want the BPEL to do a polling. Instead when I submit the BPEL process it should read all files from the directory.
I was looking at the option of Synchronous read but I am not able to specify wild card in the file name field. I do not know the file names at the time of reading.
Thanks for your help!

Hi,
While you read the file, you can configure an adapter property in 'Receive'. This will store the filename, this filename can be used for sync read as the input parameter.
1. Create a message type variable called 'fileheader'. This should be of type Inboundheader_msg (whatever relevant Receive activity).
2. This variable will contain three parts - filename, FTPhost, FTPPort
3. Copy this fileheader to 'Syncheader'.
4. syncheader can be passed as an adapter proerty during sync read of the file.
During Receive and Invoke, you need to navigate to 'Adapter' tab to choose the created message type variable.
Let me know if you have further questions.
regards,
Rev

Help required in reading a file from Shared location on Network

Hi,
I need help in reading a file from a shared location. Can you kindly tell me the pattern for inputting the shared location path. I am using fileUtilService>Exists
"\\Shiva\test\shared\eForms\temp.xlsx" is the actual location of the file. How should i input the location in the INPUT variable of EXISTS.

readResource content operation will fetch documents from Adobe Repository. Unless you checkin the required file into repository, the above error will remain.
From a shared folder, you should able to read the files using readDocument (using FileUtils) without any issues. Perhaps, the access rights prevent the execution.
If you are running JBoss as a windows service (turnkey will create a windows service for the JBoss instance), try the following:
Run -> services.msc -> Right click on JBoss service for Adobe LiveCycle -> Properties
Check the value given under logon tab. The User Account mentioned there should have appropriate access to the shared folder you are attempting read.

Need help with EXS24 "read velocity range from file name"

I am trying to import 127 drum samples to a single key using the option shown here. The option says "Map to key dropped on and read velocity range from file name". I can find no documentation in the manuals on how to do this. What is the syntax required in the file name to make this work? I need to do several of these imports. The capability is cleary there, but I need help on how the file name should be formatted. My thanks to anyone who can help.

Hi
Not a direct answer to your question, but if you are doing a lot of sample mapping etc, you may want to check out Redmatica's KeyMap Pro or the simpler Keymap 1:

Read a xml file from local directory, transform it and put in new local dir

Hi,
I have a simple requirement. I have one XML file in d://source folder. I want to read it, transform it and want to put the transformed xml file in new location d://target.
I am new to OSB. Please help me out to complete the above requirement.
Thanks in advance.
Cheers.

Use a polling file transport proxy service to read the file(d://source folder)
Do the necessary transformation XML or MFL(if the file is fixed length strings) in the proxy service stages.
Use a file transport business service to write the file to a directory(d://target).To be called from the proxy service route node.

How to open and read many files from a directory and store contents in 2D array?

I want to make a VI that opens and reads the data from various files contained in a directory (200 files each with 2 columns) and store these in a single 2D array. For file number 1 I want to store the data from both columns in the 2D array, but for files 2 to 200 I only want to store the second column of each file. Can someone please help?

Hi Nadav,
Thanks for your help. I have followed your instructions but i cannot get it to work. I used the LIST DIRECTORY to list the files in the directory - that works. However, how do I read each of the 200 files using READ FROM SPREADSHEET FILE without me having to manually select each of the 200 files? So, if I use LIST DIRECTORY to list all 200 files in an array, how do I get each of these to open and store the data in a 2D array? Here is what I have done (File called read_files.VI) Could you please help me? Thank you very much in advance.

Help with writing, reading a file...

I'm writing a program that writes a number to a file and then reads it again each time it is loaded. It's like a counter, the number starts out being 0, then when the program is run again the number will be two, and so on and so on. I've never been good with writing incrementer type things and files, so could you help me out? Remember, the program writes a single number to the file, and then adds one to that number each time the program is run, so it starts at zero and goes up by one each time it is run.
-Thanks... I just came back from vacation and my Java skills are somewhat lacking :P

open old file -> get the number -> create a new file -> write new number

This is driving me crazy!!! Help with first time exporting files from computer to MP3 Pla

Hello All.
I'd REALLY appreciate any guidance here. I bought a USB converter to USB 2. My computer does detect it, but I cannot find it when I go to the sources and go under my computer. All that comes up at that point is the A,C, and D dri'ves. When I go to my computer icon on my desktop it shows Creative Zen as on there. Does anyone have any tips on how to get the USB dri've to come up under sources?
This is so much work to be putting into just getting some music into this player!!!
Thanks so much.

Go to: My Computer/Control Panel/System/Device Manager. Scroll down the Device Manager menu until you see USB devices. If there is a yellow triangle beside one of them, you probably have to update the driver from the install CD that your USB 2 card came with.
Reboot and it should be OK.

Help with calling a batch file from projector

Hi all. I have been asking a fair number of questions here recently and have been very pleased with the responses, so here is one more for you. Hopefully I can get another solution. :]
I have a flash project acting like a menu and being published as an .exe (projector). In this file, I have a button with the following code:
button1.onRelease=function(){
fscommand("exec", "openfiles.bat");
I have an fscommand folder (in the same directory as my flash file) which contains the openfiles.bat, with one line:
start myfile.txt
myfile.txt is also located in the fscommand folder. When I simply click on this batch file and run it, the text file opens as it should. However, when I click the button in my flash file, a command prompt window flashes too quickly to see with some sort of error message. It says something about not finding a certain directory and defaulting to the windows directory. I'm assuming it cannot find either my batch file or my text file. I am under the impression that as long as everything is in the fscommand folder it should work properly. Can anyone offer me advice? Thanks!

How do i move a file from one directory to another?

Can anyone help me in moving a file from one directory to another?
The following code just does not work!!
File source_file = new File(source_file);
if(source_file.exists())
File dest_file = new File(destination_file);
if(!dest_file.exists())
boolean moved = source_file.renameTo(dest_file);
System.out.println("moved.."+moved);
The varirable moved is always false.
Can anyone tell me whts wrong in this code?

The problem in your code is you used file object as argument when you create a new File. I changed a little bit codes and it should be fine now.
String source_file1="test111.txt";
String destination_file1="test222.txt";
try{
     File source_file = new File(source_file1);
     if(source_file.exists())
          File dest_file = new File(destination_file1);
          if(!dest_file.exists())
               boolean moved = source_file.renameTo(dest_file);
               System.out.println("moved.."+moved);
catch(Exception e){
           e.printStackTrace();
}

Help with Read/Write File

Read a file and search the whole file for a word such as "throw" and print out the rest of that line to a new file. in the case of "throw", i want to link all thrown exceptions to the file that contained them.
can someone help me out and let me know what way I can approach in this?
any help would be greatly appreciated.
thanks!

Rough and dirty, here's a class that will read a file and return a resultset:
import java.io.*;
import java.nio.*;
import java.nio.channels.FileChannel;
import java.util.*;
import java.text.DateFormat;
public class Utils{
     File fileName;
     FileOutputStream outputFile;
     boolean closeChannel;
     //Constructor
     public Utils(String directory, String filename){
          String strFileDir = directory;
          String strFileName = filename;
          File fileDir = new File(strFileDir);
          fileName = new File(fileDir, strFileName);
          // If directory does not exhist, create it.
          if(!fileDir.isDirectory()){
               if(fileDir.mkdirs()){
                    System.out.println(fileDir + " created.");
               else{
                    System.out.println(fileDir + " could not be created.");
public ArrayList readText() throws IOException{
          // Read content of file into a collection
          ArrayList arrayList = new ArrayList();
          try{
               BufferedReader in = new BufferedReader(new FileReader(fileName));
               String line;
               while((line = in.readLine()) != null){
                    arrayList.add(line);
               in.close();
          catch (IOException ex){
               throw ex;
          return arrayList;
     }And here's how you use the class:
// Create a new Disk Utilities object. This can be used for all subsequent read/writes to this file.
          Utils utilTest = new Utils("e:/testing", "Testing.txt");
// Create a collection to hold the data from the file.
          ArrayList arrayList = new ArrayList();
          try{arrayList = utilTest.readText();}catch(IOException ex){ex.printStackTrace(System.err);}
