JSR75 Writing a file
Hi,
I writing a small application, where i want to save a string in a text file
in the device file system using JSR75
I know that it supports the writing to the files
The flow of the application is
1.i will first chk whether a directory "ABC" exists or not
2.if no then i will create it
3.then i will create a small read.txt and save the string in the txt file using DataOutputStream
But the problem is it is giving me illegal argument exception when i am opening the
connection itself when i am using Connector.open() method
Thanks
void openAndWriteFile() {
* This will simply print out the available file roots you have.
Enumeration e = FileSystemRegistry.listRoots();
while (e.hasMoreElements()) {
String element = (String) e.nextElement();
System.out.println(element);
/** Now for the example */
try {
* It is important to note that you must take the result of the values
* which come back from FileSystemRegistry.listRoots() and prepend with
* the value "file:///" before sending this to Connector.open()
OutputStream out;
// Hard code this value for demo purposes
FileConnection fc = (FileConnection) Connector.open("file:///c:/temp/myfile.txt");
if (fc.exists()) {
// Open at the end of the file
out = fc.openOutputStream(fc.fileSize());
} else {
// Create the new file and open a stream on it
fc.create();
out = fc.openOutputStream();
out.write("Line of text\r\n".getBytes());
out.close();
fc.close();
} catch (IOException ex) {
ex.printStackTrace();
}

hi,
as part of my requirement , i have to perform read and write operations of few files [ using the file upload control in my custom visual web part] and on submit button click.
but while writing these files - with the help of fileupload control - and when i use myfileupload.saveas(mylocation);
- i am saving these files into my D:\ drive of my server , where i am executing my code -, am getting access denied error.
it throws system.unauthorizedexception.
i have given full control on that folder where i was trying to store my attached files. and also after following asp.net forums,
i have added iusr group added and performed all those steps such that, the file is saved in my D:\ drive.
but unfortunately that didnt happen.
also
a) i am trying the code with runwithelevatedprivileges(delegate() ) code
b) shared the drive within the d :drive where i want o save the files.
c) given the full privieleges for the app pool identity- in my case , its
network service.
the other strange thing is that, the same code works perfectly in other machine, where the same sp, vs 2012 etc were installed .
would like to know, any other changes/ steps i need to make it on this server, where i am getting the error.
help is appreciated!vishnuS1984 wrote:
Hi Friends,
I have gone through scores of examples and i am failing to understand the right thing to be done to copy a file from one directory to another. Here is my class...So let's see... C:\GetMe1 is a directory on your machine, right? And this is what you are doing with that directory:
public static void copyFiles(File src, File dest) throws IOException
// dest is a 'File' object but represents the C:\GetMe1 directory, right?
fout = new FileOutputStream (dest);If it's a directory, where in your code are you appending the source file name to the path, before trying to open an output stream on it? You're not.
BTW, this is awful:
catch (IOException e)
IOException wrapper = new IOException("copyFiles: Unable to copy file: " +
src.getAbsolutePath() + "to" + dest.getAbsolutePath()+".");
wrapper.initCause(e);
wrapper.setStackTrace(e.getStackTrace());
throw wrapper;
}1) You're hiding the original IOException and replacing it with your own? For what good purpose?
2) Even if you had a good reason to do that, this would be simpler and better:
throw new IOException("your custom message goes here", e);
rather than explicitly invokign initCause and setStackTrace. Yuck! -

Please let me know if anybody faced similar issue earlier.
It was working perfect earlier, but suddenly error started.

Kedar KulkarniNo proper findings, but issue resolved.
Problem i found that we got a domain change and service values were not refreshed until we apply new patch.
So when we applied patch level 6 on BI WEBAPP& BI BASE S URL for ADS got refreshed and we faced the issue.
After resetting the URL to new domain problem got resolved.

I was trying to download iTunes on my computer, and while doing so, I got this message: Error writing to file: C:/Program Files (x86)/Common Files/Apple/Apple Application Support/Apple Versions.dll. Verify that you have access to that directory. I have downloaded iTunes numerous times and I have never had this problem. If anyone knows what's going on, I would really appreciate the help.
Well, there's definitely a mac and a Windows version. And you're at the right page. I think the problem is that someone forgot (or decided not to) to update the text at teh bottom of the page to have Mac and Windows.
Just push the button, you'll get the Mac update no problem.

"Error writing to file" when installing Oracle9i
I am fairly new to Oracle and have not been able to install Oracle 9i on my Redhat 7.2 box. In three attempts to install I have encountered the same error at some point, usually early on 5% or 10% into the install.
The error is:
"Error in writing to file /usr/oracle/product/9.2.0/olap/wrksht/wks.jar"
However, it has not happened on the same file each time. I have stopped the installation of that component, but it encounters the same error on other files. I have tried redownloading the oracle disks and reinstalling, but to no avail. I read on one posting that Oracle needs to have glib2.2(rather than glib1.2) installed, so I downloaded it and will be trying that later today. If anyone has encountered this error and knows how to solve it I would appreciate the help. Below I have listed my computer configuration and I have attached the portion of the install log that identifies the error that takes place.
Thanks
Ed

Hi,
Did you guys finally find solution to the problem?
I have been trying to install Oracle 9.2.0.1 on redhat 8.0 box, for ages now. I get the following error first during install
Error in writing to file libclntsh.so.9.0
Then it is a series of errors, similar.
In the end there is the dreaded linking error... for the ins_rdbms.mk sdo_on
i just cant handle it.
What the hell is wrong?
I have done everything right as far as i know... any solutions?
cheers -
I'm working on a program that asks for the users name. after that its supposed to pull the current date and time and print that into a file along with the users name.
my problem is when i open the .txt file i get several characters i dont recogize and then my name at the end.
Thanks for the help:
public class CIS314Exam1MarkWellsFrame
private ObjectOutputStream output;
public void openFile()
try
output = new ObjectOutputStream(new FileOutputStream("guestlog.txt"));
catch(IOException ioException)
JOptionPane.showMessageDialog(null, "You do not have access to this file");
System.exit(1);
public void insertName()
try
Date today = new Date();
//utput.writeObject(today);
//String name = JOptionPane.showInputDialog("Enter Name");
String name = "Mark";
output.writeObject(name);
catch(IOException ioException)
JOptionPane.showMessageDialog(null, "Error writing to file");
return;
public void closeFile()
try
if(output !=null)
output.close();
catch(IOException ioException)
JOptionPane.showMessageDialog(null, "Error Closing File");
System.exit(1);
System.exit(0);
}This isnt the correct forum for this question. Use tags when posting code. Post the contents of the .txt file and what unexpected characters you are getting.

Hi,
I have made a program that reads a string, converts it to bytes, then writes to a file.
Well i got the first two working, but its not writing to file. I know it should work cos i have written to file on my previous tests, but when i used a FOR loop it stoped working. Do ya know why. Below is the code...
for (int a = 0;a = bytes.length - 1;a++){
of.write(bytes[a]);
System.out.print(" " + bytes[a] + " : " + bytes.length);
My friend told me to use bytes.length - 1 as it is meant to stop the OUTOFBOUNDS error.
OK,
my regards
Below is the whole program, its a bit messy cos i got lots of old code that i have blocked.
import java.io.*;
import java.awt.event.*;
import javax.swing.*;
import java.lang.String;
public class sender implements Runnable {
int i= 0;
String mes;
int count =0;
int b = 0;
boolean yes = false;
public static void main (String[] arguments) {
Thread th = new Thread (new sender());
th.start ();
//sender();
//while (true){}
public void run() {
try {
Thread.sleep(100);
} catch (InterruptedException e) {}
String mesdialog = JOptionPane.showInputDialog(null,
"Enter your message");
mes = mesdialog.toString();
try {
//FileOutputStream of = new
//FileOutputStream ("send.txt");
FileWriter of = new
FileWriter("send.txt");
//BufferedReader in = new
// BufferedReader(fr);
//while (true){}
int i = 66;
boolean eof = false;
int inChar = 0;
//String inChar;
byte[] bytes = mes.getBytes();
/* < disable / enable
do {
int n=Integer.MIN_VALUE;
try{
n = Integer.parseInt(mes);
} catch (NumberFormatException nfe){
//inChar = n;
if (inChar != -1) {
byte outChar = (byte)inChar* ;
//char outChar = (char)inChar ;
of.write(outChar);
System.out.println("" + outChar);
//of.write(mes,0,20);
} else
eof = true;
} while (!eof);//*/
for (int a = 0;a = bytes.length - 1;a++){
of.write(bytes[a]);
System.out.print(" " + bytes[a] + " : " + bytes.length);
while (!yes) {
if (bytes[b] == 32 )
yes = true;
else {
of.write(bytes);
System.out.print(" " + bytes[b]);
b++;
//System.exit(0);
//outfile.write(input);
} catch (IOException e) {
System.out.print("AAA ERROR");}your friend was obviously wrong.
for (int a = 0;a = bytes.length - 1;a++){ // that does nothing
of.write(bytes[a]);
System.out.print(" " + bytes[a] + " : " + bytes.length);
}the above "for" loop says :
1:initialize a with 0;
2:do loop while a=bytes.length(<-that's completely wrong. it should be
a boolean expression);
3:for each loop increment "a" by one.

after retry..again SharePoint Designer requires the following component require to install Microsoft.NET framework version 4 i have downloaded and try to installed but fail not work please answer what to do?
Thanks and Regards, Rangnath MaliHi Rangnath,
For running SharePoint Designer 2013, you need to install Microsoft .NET 4.0 Framework or higher.
Please uninstall the Microsoft .NET 4.0 Framework, and install it again. After that, reboot your machine.
Best Regards,

i ve used the above code to read an input from the user now i want to write this to a file.plz tell me how to do itya i tried using FileWriter
But is there any other methods
import java.io.*;

System.out.println("Enter something: ");
str1=inpu.readLine();
System.out.println("hai"+" "+str1);
//opening a new file for output
File outfile_1= new File("testout.txt");
//using filewriter class for writing to file
FileWriter out= new FileWriter(outfile_1);

Writing to file in JUnit test case? Not working?
I have a singleton class called InstantLogger that internally uses a PrintWriter to write to file. It is very basic, has startLogger(String filename), log(String msg), and stopLogger(). startLogger just creates file, log write to file, and stopLogger closes file.
When I use this class outside of the JUnit test suite it works fine.
As soon as I use it in a JUnit test it does not write to file. It creates the file (this happens in the TestSuite), but will not write anything to it (when log is called from TestCase). I put a System.out in the log function and I see that, but still nothing writing to file. And I will say it again, it does work in non TestCase scenarios so I know it works.
Is there something that could be preventing me from writing to file in JUnit TestCase? Could this be a Singleton Issue?

Your code is wrong. You're assuming something that isn't correct. You're also making the assumption that just because it "works" in another context that it's right in all contexts. The two aren't the same, be it configuration or something else.
Singleton? That GoF pattern has been voted off the island. Didn't you hear?

Writing to file with ObjectOutputStream
ApartmentWriterProgram asks information about apartments
and saves it to a file.
For some reason it doesnt save information, it writes:
Writing to file "+file+ " failed.
So there happens IOException in the method write(Apartment apartment).
Or in the run().
I dont know what's wrong. Do you?
public class ApartmentFileHandler extends Object implements Serializable {
private OutputStream outStream;
private ObjectOutputStream obStream;
private String filePath;
public ApartmentFileHandler(String filePath) {
this.filePath = filePath;
/** Writes the given apartment data in the file. If the file already
exists, the old contents are overwritten.
Parameters:
apartment - the apartment to be written in the file
Throws:
IOException - if other problems arose when handling the file (e.g. the
file could not be written)
public void write(Apartment apartment)
throws IOException {
outStream = new FileOutputStream(filePath);
obStream = new ObjectOutputStream(outStream);
obStream.writeObject(apartment);
import java.io.*;
import java.util.*;
public class ApartmentWriterProgram
extends Object
private KeyboardReader keyboardReader;
private List roomsInList;
private Room[] rooms;
private int numberOfRooms;
private String file;
public ApartmentWriterProgram()
this.keyboardReader = new KeyboardReader();
this.roomsInList = new ArrayList();
this.rooms = new Room [numberOfRooms];
/** Runs the writer program. The program asks the user for some
apartment data and a file name, and saves the data in the file. */
public void run() {
try {
numberOfRooms = keyboardReader.getInt("Give number of rooms: ");
for (int i =1; i<numberOfRooms+1; i++) {
String type =keyboardReader.getString("Give " +i+ ". " + "type of the room: ");
double area =keyboardReader.getDouble("Give " +i+ ". " + "area of room: ");
Room room= new Room(type, area);
this.roomsInList.add(huone);
roomsInList.toArray(rooms);
Apartment apartment = new Apartment(rooms);
System.out.println();
file = keyboardReader.getString("Give name of the file: ");
ApartmentFileHandler handler = new ApartmentFileHandler(file);
handler.write(apartment);
} catch (IOException ioe) {
System.out.println("Writing to file "+file+ " failed.");
public static void main(String[] args) {
ApartmentWriterProgram program = new ApartmentWriterProgram();
program.run();
}There is nothing to gain in not putting the throws IOException in the write method, since the exception object will have the information about the actual problem.
Is this a typo for the this post? this.roomsInList.add(huone); should be room nes pas.
What exception is actually thrown? To find out useSystem.out.println("Exception: " + ioe);Then wonder why you have the AppartmentFileHandler implement Serializable when you are not writing that object to the file. -
Hai,
I am installing Oracle9.2.0 on my RH8.0 system. I got an error like this after running runInstaller: Error in writing to file: .../oracle/jre/1.3.1/bin/i386/native_threads/java
Someone know a solution for this ?
thx
rameshYour error has been completely addressed here http://www.puschitz.com/InstallingOracle9i.html. This is very informative. You may want to check this out before proceeding. The straight solution to this is when this error shows up, leave it open, find the native_threads/java file from the CD to the directory Oracle is asking for this. I had this problem and it turned out when I extracted and burnt it to a CD, it didn't copy the native_threads directory and others, so you want to check this as well.
