      InitialContext ic = new InitialContext(env);

Do NOT use cancatinate string to build up file paths. You are just asking for issues. That is what Build Path is for, and it reduces the amount of work you have to do.

Writting file issue

Hi,
I am trying to write a file through peoplesoft Application Engine and FileLayout where I need to write long data type field which has large text with special characters like : , | " ; ! etc and the long type field has also next line within itself. so while writing file data is not written properly.
EPM table has long type data field which stores Manager's appraisal comment, reviewer's appraisal comment.
Any help in this point would be appreciated.
Thanks..

Thanks for your quick reply!!!
file doesnot look in expected format. But expectation is each field should populate in single spreadsheet cell in a single row. the following data are coming for a single row from a aprticular record and each data should be populated in a cell of Microsoft XLS workbook or any other file. here given last bold lines coming as a long data type which creates problem.
As an example of single row given below:

WARNING: Cannot "Read or Write" files on iPod

My iPod has been behaving very curiosly as of late. For the past month a wanring has flashed up on my iTunes screen when attempting to sync music files. The warning says *"Cannot read the disk 'iPod'. Unable to read or write files"*. Despite this warning my iPod has been able to update daily podcasts without issue. However, when I recently purchased new music I could not get it to sync to my iPod. I have no problem listening to this new album in my iTunes library, but it just will not sync to my iPod. I created a playlist for it and attempted to add it, but I discovered that the iPod was not syncing the playlists either!
In a recent attempt to remedy the problem I selected only to sync the playlist that had the new album. What happened was frightening. All my music was no longer on the iPod, with the exception of my podcasts! I tried altering the settings to return all the music, but now I am unable to add any of my music from the library.
I am wondering if anyone has experienced this difficulty before, and if so, if they have any trouble shooting techniques. I have already been ti Apple's support page and completed the 5 recommended steps, to no avail. Any suggestions or thoughts as to what might be occuring.

Luckily, backing up your itunes library is easy. Just duplicate the folder(s) with your music in it. (Most likely, it's user/Music/ITunes.) Once the copy is made, you might want to move it to a different part of your hard drive.
Now, restoring your ipod WILL wipe the device. If there's anything on your ipod that isn't in your itunes library (unlikely but possible), you want to make sure you've got a copy of it somewhere before restoring.
Before restoring, check to see if there is an update to the ipod's firmware that needs to be installed. This is a "longshot" but might help. Just click the "check for update" button on the ipod's "Summary" pane in itunes. (Current version is 1.2.3, I think).

How to write file at server end?

Hi,
I use a af:inputFile component to receive uploaded files. And want to write files to the directory of server. However, when execute java.io.File.createNewFile(), it throw exception. How to resolve it?
import org.apache.myfaces.trinidad.model.UploadedFile;
import javax.faces.event.ValueChangeEvent;
import java.io.InputStream;
import java.io.File;
public class UploadFileHandler {
    public void doUpload(ValueChangeEvent event) throws IOException {
        File file = new File("C:\temp.txt");
        *file.createNewFile();* //Error happen here.
}

Hi Cheney,
It is good practice to use System.getProperty("file.separator") instead of hardcoding "/" or "\" .
Though your issue is resolved by using "//", you might want to consider changing to the above.

Oracle 11g on Unix server needs to write files (.csv) on Windows server

Hi,
Currently we are using Oracle 10g which is installed on a Unix server and on the same server there is a directory under which some files are being exported/downloaded by the db.
We are having DEDICATED DB INSTANCE on the SHARED server, and not a DEDICATED SERVER.
Now we need to migrate from Oracle 10g to 11g, but due to some complaince issue, we have been asked to create those directories on some other server. We have identified a Windows server and can create directories.
Now I request any expert to pls suggest/guide me that how can the db (on Unix server) export/write files on another Windows server?
I read in a thread that the server (where files should be exported) should be MOUNTED on the server where db is physically installed.
Pls help me here.....

Or if network connectivity to the remote server fails? Or if there is severe network congestion between the Oracle server and remote server? What then?
How is the process on the local server suppose to deal with errors when it attempts to create a CSV file on the remote server? Or deal with network bottlenecks that results in severe performance degradation when trying to create a CSV file? Or if there lacks freespace for creating the CSV file?
What about security? How is the local Oracle server to authenticate itself with the remote server? How is the remote server to protect that directory share against unauthorised access?
How is this remote server going to provide access to authorised s/w to these CSV files?
Who (local or remote processes) is going to manage this directory share and ensure old CSV files are deleted and that there is sufficient freespace for new CSV files?
There are a LOT of questions that need to be asked... BEFORE deciding on HOW technically to do it. As the technical decision will be based on the functional requirements and how to best meet these.
Technically - there is Samba, NFS, FTP, SFTP, SCP, RDIST and a number of other methods that can be used. But without asking the above questions and getting proper business answers, selecting a specific technical method is very much premature.
You are asking the wrong questions, and in the wrong forum. You need to determine the business requirements first.

Write file error 8

Once the file is created subsequent writes show Error code 8 out of the "Write File" VI LV6. (Cannot upgrade the code at this time). I'm using open/create/Replace File VI along with the Write File VI. Creating the file run OK, once I go back and rerun for a write the "Write File" reports Error code 8. How do I fix this issue.... using LV6.

The file created by the open/create/Replace VI attributes are NOT set to READ ONLY. See the pic below. If the LV creates the file it should be able to subsequently write to the same file. Once again this is LV version 6. It didn't work this way before... I took a look at a few things in the code and noticed this anomaly.
BTW, there are root or branch level folder showing the Read Only attribute is inherited from parent folder... but my whole C drive is this way... but LV should be able to write to the file regardless....

This has nothing to do with CC or any of that. You have insufficient user privileges to write files locally on your computer or a technical issue gets in teh way. Since you have not provided any system info or otehr details, we cannot tell you more than that.

Probleme avec Imaq write file qui n'enregistre pas les images en jpg

Bonjour,
dans le cadre d'un stage, je suis en train de dévellopper un programme qui récupère une vidéo issue d'une caméra usb. Jusque là tout vas bien. Mais je souhaite réalisé une vidéo a partir d'une suite d'image au format jpeg que le programme aura enregistrer dans un dossier.
Mon probleme etant que Imaq write file 2 que j'utilise n'arrive pas a enregistrer les image au format jpg (alors qu'il y arrive au forma png, tiff ou jpg2000). Ainsi, lorsque je lance la capture, le programme a l'air de faire des opération mais lorsque je vais dans le dossier où doivent etre entreposé les jpeg, celui ci est vide.
J'utilise labview 2010 et suis sous windows 7 x64 bits.
Merci d'avance pour l'aide que vous pourez m'apporter.

Why am I getting "Can't write file"? from jsp

I have the following code:
public String OpenRAF(String fileName) {
try {
file = new File("http://www.domain/filename.prn");
} catch (java.lang.NullPointerException npe) {
writeError(npe);
} catch (java.lang.IllegalArgumentException iae) {
writeError(iae);
if (!file.isFile()) {
retn = "Not a file:" + file.getAbsoluteFile();
if (!file.canRead()) {
retn = "Can't read file:" + file.getAbsoluteFile();
if (!file.canWrite()) {
retn = "Can't write file:" + file.getAbsoluteFile();
try {
raf = new java.io.RandomAccessFile(file, "rw");
} catch (java.io.FileNotFoundException fnfe) {
rtn = false;
Why am I getting the "Can't write file http://www.domain/filename" from this jsp?
I would like to open this file read,write and update it with the RandomAccessFile api, but I can't seem to get write permissions. I have granted 777 permissions on the file.
Is this a Tomcat file permission issue or something?
Thanks.

Thanks,
But I want to read,write to a file in the application Server. How do I get the path correct?
I want to use something like java.io.RandomAccessFile("somepath", "rw");
I should be able to access the filesystem somehow? The only way I could find the file was using the URL. Whenever I used a relative or absolute path, I could not access the file.
How do I know what the filesystem path is on an application server (Tomcat 4.1) from a Jsp 1.4?
Thanks again

Error while relocating (Can't write file (no space)) - Help please

I have been having trouble relocating master files since upgrading to Leopard. The problem doesn't seem to affect only Aperture. I can happen when using Finder or another application to move files from one drive to another. Other types of files don't seem to be affected, just my library of image files.
The copy operation runs for a while then hangs up. The application doing the copy reports an error that that's the end. Aperture gives this error message: Error while relocating (Can’t write file (no space)). The Finder reports plenty of available space on the destination drive!
I remember seeing a thread--but can't find it now--about a problem with certain xmp metatdata embedded into files causing problems with file operations.
Hoping for a solution!

It's possible that you might have a corrupt file. Have you tried to copy different files on to the destination drive? If those files copy fine, then narrow down the offending file by copying less images at a time.
