Problem with file path in linux
hi,
i have problem with file path accessing in linux. my java class is accessing a abc.cvs file and and getting all data. it is working fine in windows xp. but i run this same file in linux it does not access the abc.cvs file and does not get any data.
my project structure
Search
abc.cvs
search.SearchMain
i am sccessing this cvs file in this SearchMain class by this way file name = "abc.cvs"
It is working fine with window but problem with linux.
when i place this abc.cvs in a folder as "./data/abc.cvs" also working fine with windows but not in linux.
I am new for linux.
Please give me solution.
Thanks in advance
Ravi
forgot to tell,
then you need to export that path
export $CLASSPATH
code}

File Attachment in a Email.... problem with file path
Hi experts
I am trying to implement something similar to any email program.
A user can send email to a user along with attachments.
I am encountering the following problems:
1) in IE, the file path is set correctly, but in mozilla only the file name is set. (how do i get the file path in mozilla??)
2) if i add the file as part of the body in the email, the destination user should only see only the file name and not the entire file path of the source computer.
any help would be appreciated
thanx
deepakFile on web forms is attached to the case. Go to the case in the admin and you can retrieve the file.

Problems with file paths in ApplescriptObjC
Hi
I am having a problem with trying to Open/Read/Write/Close text files in ApplescriptObjC. The following piece of script works in Applescript but when I try to incorporate in ASOC via Xcode I get the following error "Can’t make current application into type «class fsrf»" and I have no idea what that means!
I've tried using POSIX paths but still doesn't work. As usual, any help gratefully received.
I am using the Control Record to hold the last reference number used so when I add another row to a spreadsheet it will generate the next unique reference.
set filePath "Macintosh HD:Users:Ours:Documents:Cats Protection:Control Record.txt"
set fileReference to open for access (file filePath) with write permission
set lastNumber to read alias filePath -- read all data
set nextNumber to (text -1 thru -2) of lastNumber as integer -- extract last number
set nextNumber to (nextNumber + 1) -- increment number
set nextNumber to text (2 * -1) thru -1 of ("0" & nextNumber) -- add leading zero
write nextNumber to fileReference starting at 9 -- update next number
close access fileReference«class fsrf» is a file system reference. Long story, but cocoa changed the preferred way to handle file references (in 10.6, I think) and sometimes applescript trips over the difference.
try changing the first three lines like so:
set filePath to "/Users/Ours/Documents/Cats Protection/Control Record.txt"
set fileReference to open for access filePath with write permission
set lastNumber to read fileReference -- read all data
Cocoa is generally happier with posix paths, open for access shouldn't need the file keyword, and reading from the file reference (rather than specifying the file again) is cleaner. -
Problem with file.encoding in Linux
Hello,
I am currently migrating a java project from Windows to Linux. The project is finally shaping up now, except for some encoding problems.
All configuration files are saved in ISO-8859-1/Cp1252 format. When reading and displaying these files in Swing (e.g. JTextArea), the special characters ���� are displayed wrong. I have tried to start the VM with -Dfile.encoding=ISO-8859-1 and -Dfile.encoding=Cp1252 without success (this is done in Eclipse under Linux).
I then tried the opposite. I created some UTF-8 files, started the application under Windows/Eclipse, read the files and displayed them in a JTextArea. Garbage characters were shown instead of ���� (as expected). I then used -Dfile.encoding=UTF-8, and voila, all characters were displayed correctly.
Why does not -Dfile.encoding work for ISO-8859-1/Linux but -Dfile.encoding work for UTF-8/Windows? Anyone here know?
The JRE I have been using is 1.4.2_06.
The Linux is a SuSE 10.0Continue the "discussion" here:

Problem with file descriptors not released by JMF
Hi,
I have a problem with file descriptors not released by JMF. My application opens a video file, creates a DataSource and a DataProcessor and the video frames generated are transmitted using the RTP protocol. Once video transmission ends up, if we stop and close the DataProcessor associated to the DataSource, the file descriptor identifying the video file is not released (checkable through /proc/pid/fd). If we repeat this processing once and again, the process reaches the maximum number of file descriptors allowed by the operating system.
The same problem has been reproduced with JMF-2.1.1e-Linux in several environments:
- Red Hat 7.3, Fedora Core 4
- jdk1.5.0_04, j2re1.4.2, j2sdk1.4.2, Blackdown Java

Many thanks.Its a bug on H263, if you test it without h263 track or with other video codec, the release will be ok.
You can try to use a not-Sun h263 codec like the one from fobs or jffmpeg projects. -
Problem with inifile.fp under Linux
Hello all,
I noticed a problem with inifile.fp under Linux: I can't write the updated
ini file !
hConfigFile = Ini_New(0);
if (Ini_ReadFromFile (hConfigFile, ConfigPath));
Ini_GetInt(hConfigFile, "Client", "ChartsRefreshRate", &ChartsRefreshRate);
Ini_GetInt(hConfigFile, "Client", "ChartsDuration", &ChartsDuration);
.... Change the values ...
Ini_PutInt(hConfigFile, "Client", "ChartsRefreshRate", ChartsRefreshRate);
Ini_PutInt(hConfigFile, "Client", "ChartsDuration", ChartsDuration);
if (0!=(Err=Ini_WriteToFile (hConfigFile, ConfigPath)))
fprintf(stderr, "\nWarning: problem writing %s configuration files: %s",
ConfigPath, GetUILErrorString(Err));
This fails and displays:
Warning: problem writing Config.ini configuration files: File not found
But not only that, it also deletes the ConfigPath file !!!
Which is rather unacceptable !
I see that the inifile.fp I have on the PC (CVI 8.5) is different than the
one I have on the Linux install (cvicc 8.0). Can I copy all the inifile.*
files to Linux or is it more complicated than that ?
Guillaume Dargaud
http://www.gdargaud.net/Hello Luis,
I came here to check if a new version of CVI (cvicc, not the real-time
module) for Linux had come out and, sadly, it appears that's still not the
case...
But I saw your followup to our original discussion.
The ini file has grown tremendously since then, but I think I had the
problem with even the most basic file: simple name (same directory, no
path), but maybe it was on an NFS directory (that's no longer the case).
Also the fact that instead of writting _in_ the file (where permission was
allowed) you wrote to a temp file (that may not have had permission) and
then renamed accordingly...
I'll start a new project soon that will require ini files, so I'll test it
again.

I have a problem with a pdf file which does not open with reader in windows 8 but it opens properly with adobe pdf reader. All other pdf can be opened in reader.But when i open a pdf(see this link for pdf for which i got error http://incometaxsoft.com/temp/Form.pdf)
it gives error as "Can't open this file. There's a problem with file format".
The same file opens properly in adobe pdf reader.You can check the pdf file which i have mentioned in the link above.But the reader which comes with windows 8 can open some other pdf in the same PC.What may be the error causing this??This has turned out to be an enormous issue for me as I sell PDF files as ebooks. I have done a fair amount of investigating this for my system.
My files have to be compatible not just across readers but across operating systems.
To date, I have over 200 PDFs that have functioned flawlessly across Mac, PC (Windows 7 and below), Android, iPhone/iPad, Linux.
I personally test my PDFs using a variety of readers and PDF editors including
PDF XChange (my favorite)
Foxit (runner up for me and I recommend for most people)
Adobe (the bloated monster)
Nitro 9 (great for moving graphical elements around)
ABBYY
And the Nuance PDF Create toolsets
Those are off the top of my head. There are a bunch on Android that I test with too.
I am running the Windows 10 Pro Tech Preview and I have this same problem so I know it isn't fixed yet in any kind of pre-release way (-sigh-)
Here is what I've learned for my situation
The PDFs I created using NUANCE'S PDF CREATE PROFESSIONAL VERSION 8
all fail using the built-in Windows 8/10 PDF reader.
When I look at the PDF properties for these Nuance created files, the underlying engine used to write them is called "ImageToPDF". Using ABBYY it indicates their own engine as does everyone else that I've tried. It is easy for you to check to see
what created your PDF by doing a "Control D" (look at the document properties). Perhaps there's a common engine causing issues.
If I use the exact same source files to create a PDF using any of my other tools I have no issues. I checked the PDF versions made by the tools and they are all set to 1.5.
A customer mentioned being able to convert them in a way they worked by saving them without having to do any kind of extraction, but I have not been able to duplicate that. Perhaps he did a "print" which seems like it could work.
In summary, the workaround everyone is talking about, using an alternate reader, of course works. But not everyone wants to change.
The culprit I have found is my Nuance PDF Creation tools that are using the ImageToPDF engine.
I hope it gets FIXED as I really don't want to have to regenerate all of my PDF files. -

kari-mattiHello again.
I'm still having problems with this. I made
a simple servlet that reads from and writes
to text file. The reading part work fine on my
computer, but the writing doesn't, not even
an exception is thrown if the file exists that
I'm trying to write to. If I try to create a new
file I'll get an exception about file permissions.
I also asked a friend of mine to try this same
servlet on his windows computer and it works
as it should.
Here's the code
import javax.servlet.*;
import javax.servlet.http.*;
import java.io.*;
public class ReadServlet extends HttpServlet
public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
String s = "";
PrintWriter out = response.getWriter();
String docroot = getServletContext().getRealPath( "/" );
out.println("docroot: "+docroot);
File file = new File(docroot+"test.txt");
if(file.exists())
s = readFile(file);
out.println(s);
else
out.println("file not found");
//file.createNewFile(); // causes exception
//out.println("new file created.");
writeFile(file, "written by servlet");
out.println("Now look in the file "+file.getPath());
out.println("and see if it contains text 'written by servlet'");
public void doGet(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException
doPost(request, response);
private String readFile(File file)
FileInputStream fis = null;
BufferedInputStream bis = null;
DataInputStream dis = null;
String s = "";
try
fis = new FileInputStream(file);
bis = new BufferedInputStream(fis);
dis = new DataInputStream(bis);
s = dis.readLine();
fis.close();
bis.close();
dis.close();
catch(Exception e)
e.printStackTrace();
return s;
private void writeFile(File file, String s)
FileOutputStream fos = null;
BufferedOutputStream bos = null;
DataOutputStream dos = null;
try
fos = new FileOutputStream(file);
bos = new BufferedOutputStream(fos);
dos = new DataOutputStream(bos);
dos.writeChars(s);
fos.flush();
bos.flush();
dos.flush();
fos.close();
bos.close();
dos.close();
catch(Exception e)
e.printStackTrace();
}And if someone wants to test this servlet I can
give a war package.
Any advices?

NT security problems with file I/O
I have 2 problems with file I/O. When I read from a file I use the getAbsolutePath() method that is part of the File class to find what directory the files are currenlty. The problem is that the returned path says that the file is on the desktop no matter what directory the file really is in. The second problem is that I am unable to save files anywhere but the desktop. I must run the class files from the desktop too to get it to work.
I am using NT 4.0 for development. I'm guessing that these problems might be NT security related. Could someone help me?

I have a problem with file-roller.
When I open an achieve file with file-roller, I can not directly open the file in the file-roller. "Open with" does not work either.
But if i use sudo for file-roller, "open" and "open with" do work.
How can I use "open" and "open with" without sudo for file-roller?
Can any body help me ?Hi,
The link is working... it's not a nautilus quirk. Try these examples:
FIRST EXAMPLE:
Login as root and edit mimeinfo.cache (In openSUSE, the linux distribution I'm using right now, this file is placed on /usr/share/applications).
su
gedit /usr/share/applications/mimeinfo.cache
Search for audio/mpeg=
The first application I specify is going to be the program that File-Roller will use to open a compressed mp3 file.
Example:
audio/mpeg=totem.desktop;banshee-1.desktop;
This will open Totem...
audio/mpeg=banshee-1.desktop;totem.desktop;
This will open Banshee.
SECOND EXAMPLE:
$ su
$ gedit /usr/share/applications/defaults.list
Search for:
text/xml=MozillaFirefox.desktop
Replace to:
text/xml=gedit.desktop
This will open xml files with Gedit, instead of Firefox.
Good luck.

How to work with file system in linux within a JSF app?
I use this line in my backing bean to log some events:
FileHandler fhxml = new FileHandler("../webapps/MyWebApp/Log/MyWebAppLog.xml", append);
fhxml.setFormatter(new XMLFormatter());That works fine in windows but when I deploy it in my Tomcat 6 in linux It doesn't work. How can I work with file system in linux?You should never use relative paths to access the filesystem. The path would be relative to the current working directory which is not per se the same in all environments. To convert a relative web path to an absolute file system path, you need ServletContext#getRealPath(). Use this absolute file system path in the java.io stuff. In a JSF application on top of Servlet API you can get the underlying ServletContext by ExternalContext#getContext().
Alternatively, if the file is located in one of the default paths of the classpath or if its path is added to the classpath, you can also just use ExternalContext#getResource() or even #getResourceAsStream() using just the file name. -
What's problem with File Panel?
Hi All!
I'm web designer, while developing my site, my work is
breaking a problem with File management of DMX.
First, I develop site in DMX8 (ASP + SQL), then when I open
that site in DMXCS3 - Note: all file still in only one Folder in
HDD on (D\: Drive), (example: photo-editor.asp), this file content
is last time modify. And when I open again this file in DMX8 - the
file content of this file (photo-editor.asp) not same with new
version in DMXCS3. It is old version!.
I don't understand why that. (note: I don't check Enable
cache in Local info in Site Definition). Please help me about this
problem!
Thank for All!Are both versions (DW8 and DWCS3) using the SAME local site?
Look in your
site definition in both versions of DW, and tell us what the
path is to the
local root folder, please.

Problems with File Transfers Over Firewire 800
Problems with File Transfers Over Firewire 800.
Over the past month, I have had problems when transfering files from my harddrive, over Firewire 800 to a portable drive. I usually transfer very large files (20gb or more) to the portable drives for moving files around. When I drag a file over to copy onto a drive, the transfer starts normally. If I drag more files to copy over, the computer screen goes darker and a large icon comes up that looks like a power button icon. It tells me to restart, so I have to do a hard shut down on my G5. Weird. I also get the dark screen of death sometimes when I am transfering those large files and open another application to do some work while it's copying. It's killing me. I am having to sit here and wait for the transfer to finish before I can do anything.
Any thoughts...

I suddenly encounter this error message from Fire Fox.
Could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem. If you continue to use this session, you might see incorrect application behaviour when accessing security features.
I uninstalled the browser and download a new version but it does not resolve the issue.
I know my hard disc has ample space. I do NOT know where to find the Profile directory to fix the read restriction box.
