J2me file access problem

hi,I try to read and write a file with j2me. The file which is file.txt in the root1 directory in filesystem.when running one emulator i can access the file,but running multi emulator cant access the file.Seeing "file not found" error.
How can acces this file by two or three emulator?

can u send me the code for reading a file from root in linux platform
and how can i read a file that can travell within MIDlet suite like the images
in /res folder mail me at [email protected] i have tried the following segment
having no success
public void writeFile()
FileConnection fc;
StreamConnection conn = null;
InputStream is;
try{
OutputConnection con =(OutputConnection)Connector.open("file:///root/riz.txt",Connector.WRITE);
OutputStream out =con.openOutputStream();
PrintStream ps = new PrintStream(out);
ps.println("rizwan");
ps.close();
con.close();
}catch (Exception e){System.out.println(e);}
hoping for an early reply

Perl/DB_File file-access problems on Solaris 86

I have Perl software that runs fine on Apache/FreeBSD using DB_File. I have
just ported that software to an Apache/Solaris 86 server, and the DB_File
file-access is not working.
Specifically it breaks down at the tie statement - where I am trying to tie
to an existing DB_BTREE file - saying things like "Cannot tie to file
because it already exists". Which sounds like a file access mode problem.
I use O_CREAT|O_RDWR as the file access mode parameter, asking the tie
function to create the file if it does not exist or to open it on a
read/write basis if it does. I 'use Fcntl' to set the mode parameters that
are (supposedly) correct for the system.
Any help or suggestions?
Many thanks

There are a few things possibly going on:
1. The problem where the Berkeley DB example is not being found is related
to the default tar program on Solaris, which doesn't handle long file names.
The result is that some files don't make it. The simplest solution is to use
a gnu tar if you can.
2. The Compiler issue in Xerces may be that the default compiler found is the
Solaris compiler, and not g++/gcc if that's what you want. The compiler can be
specified using the -c <C compiler> and -x <C++ compiler> flags to buildall.sh.
e.g. buildall.sh <other options> -c gcc -x g++

NFS File Access problem

Hello,
I am having problems trying to "tail" an existing file.
When the file is being written into, I can tail it without any problem.
The problem rises when the file is already complete, and I try to open it.
I tried to make a small demo program but for some reason I am unable to get the demo program to give the same behaviour.
Below is the class in which it all goes wrong.
I basically opens the file usring RandomAccessfile.
when I try to retrieve the length of the file a bit further, my ascii file I am viewing already changed to .nfs01231353434 something.
But all gets displayed ok.
When I then close the text pane in which this tail class is logging, the file itself is deleted.
As this has something to do with NFS here is the setup :
The java jar file is located on a remote solaris disk, so is the ASCII file I am trying to view.
The local machine where I am running my application is Red Hat Linux 3.2.3-52.
Apologies if this information is kinda vague but as I am unable to supply a demo program, I dont know else how to explain my problem.
The class that does the "tailing"

Time Capsule (A1409): slow file access problem and how do we create a back up of the files on timecapsule?

Time Capsule: We have a model no A1049 our network (installed by someone no longer working with us, so I don't know how it was set up or how to access any settings other than via Airport Utility)
We use it for our central file storage, and as a disk for timemachine backups from the several macs we use here.
The time capsule is running but we have slow access to files, it takes ages to bring up the list of files available, can I fix this?
I have just updated the firmware.
I would also like to know how I can back up these files to another disk.
I have searched the manuals and also the support community but I can't find the answers or any instructions other than the manuals and would appreciate help.
Thank you

The Time Capsule was designed to handle Time Machine backups from one or more Mac computers, and it will work reasonably well for that purpose.
But.....and this is a big BUT......it will not work very well at all if you try to make it act as a file server, since the disk spin up time is quite slow among other things like slow read times from the disk.
Suggest that you get with an IT specialist who can recommend the right file server solution for your network based on your needs.
As far as backing up the data on the Time Capsule, the simplest way to do this is connect a USB drive to the USB port on the Time Capsule and use the built in Archive function in AirPort Utility to make a complete copy of all of the data on the Time Capsule.
Unfortunately, the simplest way is also the slowest and the Time Capsule will not be available for Time Machine backups or file serving during the Archive procedure, which will likely take 4-6 hours or so depending on how much data might be on the Time Capsule. A good time to do this might be late at night, so the Archive copying will run overnight.
Another better option would be to use a commercially available application, like Carbon Copy Cloner to automatically back up the Time Capsule disk each day at a time that you choose. The advantage to doing it this way is that CCC will only back up the changes that have occurred since the last back up, so once the first "master" backup is done, the subsequent "incremental" backups will only take a few minutes each day.
Your IT specialist / consultant will likely have other suggestions for you as well. The advice that we have offered here is meant to be general in nature and not specific to your particular needs.

Application Server file Accessing problem

Hi all,
    In my program i am writing data to the application server file ( temp.txt ) in Appending mode.
I am having 1000 records to write. In the mean time ( while temp.txt have 200 records ) i am running the same program using same application server file ( temp.txt ) same client but different user. That time writting option for both programs are successfully done.
But in my case i have to restrict the file writing at that time only one user.
Is there any way to lock the application server file for particular user while writting.
Thanks in Advance,
Florian.

Applet file access problem

Hi, I am new to applets and I am trying to build an applet that needs input from other files on the server. How can I give my applet access to these files? I found some code with URLConnection, but I cannot seem to make it work. I am getting AppletNotLoaded appearing on the bottom of the webpage. Here is some of the URLConnection code, if anyone knows of mistakes in it:
URL url;
URLConnection urlConn;
     //DataInputStream     cfile;
     url = new URL(getCodeBase().toString() + "/R2Code/ourcode/data/"+filename+".con");
     urlConn = url.openConnection();
urlConn.setDoInput(true);
urlConn.setUseCaches(false);
BufferedReader cfile = new BufferedReader(new InputStreamReader(urlConn.getInputStream()));
//BufferedReader cfile = new BufferedReader(new FileReader (filename+".con"));
     cfile.readLine();
     StringTokenizer st = new StringTokenizer(cfile.readLine());
I am trying to read in a text file, which has the ending ".con" if that concerned anyone. Any advice would be great, thanks.

Troubleshooting file access problem

using finder, going into a sub folder in my documents folder, finder blows up... disappears, no message, nothing, just goes away. If I go in via terminal, everything is there in the correct folder and accessible. I can even gently go in using finder and opening up the folder hierarchy clicking on the delta flags I can see the listing.
this is a restored directory from time machine. I ran the disk utility to check permissions, that didn't seem to help. any suggestions?
Thanks

So Finder relaunches when you try to access a subfolder - or quits but fails to relaunch - but only on the documents folder? You might try looking at the system logs in console but first I'd do the basic thing and blame a corrupted .plist for Finder.
I would then move the files out of the documents folder - since you can get at them in terminal - and try making a new folder. You might have to do it in parts, half and then half and if the second half crashes do that half by half, etc.
I wonder if it's possible that some folder action has been attached to a subfolder and that script is crashing Finder. You might be able to see that in console logs.

Computer file access problem wrt54g

i have a wrt54g hooked up to 2 computers the the back computer can access the front one and use its printer but the front computer cannot access any thing on the back computer i have turned file and printer sharing on and still says i do not have permissio9n to access that computer. any help would be appriciated
Message Edited by burkes on 09-16-2009 09:57 AM

Make sure both the computer's are in the same workgroup...
The default workgroup name in Windows Vista has been changed to WORKGROUP. In WindowsXP, the default workgroup name is MSHOME...
Also go into the computer software firewall on each computer, and set it to "trust" the other computers on your network.
If your firewall or PC security program keeps a list of trusted applications (also known as a "trusted zone"), then make sure that your router is in the trusted zone on your firewall...

Swing file access problem in browser

I have created a applet program in swing. The output displays in browser(IE). In the applet, i put a JTextPane.
1) Is there any way to open the local file ( html/ text) to the TextPane from the local file system.
2) Is there any way to save the content which is typed in the JTextPane as a html or text file t o the local file system.
Is this possible or not from a browser applet?
if it possible, Pls give me an idea or examples.
GOVARTHANAN

you might create a jar-archive for your applet and include the html-file inside.
so you should be able to load the file from inside the applet.
hope it helps :-)

File access problem while using BULK INSERT

I'm creating a script to automatically convert a large mess of data. Here's a test query I was using to bring a file into the database:
INSERT [ImportTestTable]
SELECT a.*
FROM
OPENROWSET(
BULK 'D:\TestFile.csv',
FORMATFILE = 'D:\TestStyle.fmt',
FIRSTROW = 2
) AS a;
SELECT * FROM ImportTestTable
I've used queries like this on other networks and machines before, but when I run that query on the particular machine I'm working with now, I get the following error:
Msg 4861, Level 16, State 1, Line 13
Cannot bulk load because the file "D:\TestFile.csv" could not be opened. Operating system error code 21
(The device is not ready.).
Here's some relevant facts I can think of that might help:
I am running the query from SQL Server Management Studio on a remote machine running Windows 7 Ultimate. I am connected to this server using SQL authentication. I believe we are on the same domain / network. I am not the DBA. I do
have the permission "Administer Bulk Operations" explicitly granted to me by the DBA. The user I am currently logged in as in windows is capable of opening, editing, and saving the file in windows explorer. The format file is a NON-XML
format file.
Any pointers as to where to look for more detailed information would be greatly appreciated!

I know this is a little old by now, but this is what I used just this week:
bulk insert [dbo].[Test_Table]
from 'C:\Documents and Settings\rshuell\Desktop\Test_File.txt'
WITH (
FIELDTERMINATOR=',',
ROWTERMINATOR = '\n',
KEEPNULLS,
FIRSTROW=2
That worked fine for me.
Of course, we Naomi stated, the file has to be ON THE SERVER. Or, if you're using an FTP site, for instance, the path would have to point to the FTP site.
Knowledge is the only thing that I can give you, and still retain, and we are both better off for it.

Constant file permission problems

Hello out there..
I'm currently trying to sort out a problem with - what I guess is my - file permissions.
The problem reappears, even after a long disk repair session, where loads of issues are found and repaired.
At the end it says everything is ok, but if I click repair again, it starts again , and even after restart, the problem is back again?!?!
I've set my permission as follows, (to those of you who doesn't speak Danish - it's "read & write"), but it still says I have "special access"?
Why? and what can I do to fix it..
Please help me..

Disk Repair or Permission Repair?
Long list from a Permission Repair that come back is normal. Nothing wrong. See http://support.apple.com/kb/ts1448
Long lists of problems from a Disk Repair that keep coming back is bad news. Likely failing disk.
Special Access means you have Access Control List entries set for the particular directory/file.
Did you every change permissions and then "Apply to Enclosed?"
Do you actually have file access problems, or are you just repairing permissions and think the long list indicates a problem?

Problem in compiling j2me file

Hello friends,
friends my problem in compiling j2me file..
when i compile my j2me file through WTK2.2 (toolkit)
then it creates extra file including j2me" .class" file..
for example if my j2me file is "aman.java" and when i compile it
then it will covert into "aman.class" file but it creates one more file like "aman1$.class" ..plz help me to get out of this problem..coz its increase my j2me file size..
thanks
Aman

That is an inner class in aman.java that you are seeing there.
If you use inner anonymous classes, for example;
public class MyMIDlet extends MIDlet {
   // code for the MIDlet
   // Anonymous inner class
   setCommandListener(new CommandListener() {
      public void commandAction(Command c, Displayable d) {
        // implementation;
        // may access MyMIDlet's private fields
}then the command listener you create will become another class named MyMIDlet$1.class.
In this example you can get rid of the inner class by making one of the existing classes implement that CommandListener interface:
public class MyMIDlet extends MIDlet implmements CommandListener {
   public void commandAction(Command c, Displayable d) {
     // implementation;
     // may access MyMIDlet's private fields
   // code for the MIDlet
   // Instead of the anonymous inner class, we can now use MyMIDlet since it
   // implements CommandListener
   setCommandListener(this);
   // etc. etc. etc.

File access/locking problems, most notably with AutoCAD

A number of sporadic problems of AutoCAD users who've been working away
suddenly not able to write to the file they've been working on. If
multiple people try to use the same Xrefs, often some will get that the
file is corrupted report by AutoCAD.
What is reproducible is one of the Xref problems and it has given us a
bit of a work around to keep working.
To Reproduce:
Start AutoCAD(2009), open a file with base(Xref)
Save the base (no change needed) without closing, and refresh
the base disappears from view, and when we look in the 'Xref Manager'
we see that the Base has a status of 'Needs Recovery'. This applies
even when multiple people had the Xref in read only view, that it is
now unavailable, but when the full drawing is shut down and reopened
by the one who had saved, the Xref is just fine.
Autosave is not triggering the problem.
This has been reproduced on the newest version of ACAD as well, just
slightly different wording of errors.
OES2 sp3 servers (in VMWare) with mostly XPsp3 clients but a few
Windows 7 ones as well. The clients mostly have the newest clients
installed, but there are some of the XP boxes with 4.91.4 still on
them.
Just migrated the main data volume from NetWare 6.5.8 to OES2 Linux and
immediately started having the problem. 100% of file access is via
NCP. no CIFS is configured, to the point we have cross-protocol-locks
set to 0 (Zero, i.e. Off).
I think I've been through every combination of file locking settings of
server vs workstation without any apparent change.
Still working out different tests to do to find what makes a
difference.
Observations that might just lead to clues toward the root cause:
- On NetWare, if a user left files open over night, we could still see
those being listed as opened in Monitor. Past history with these users
is that there was always several showing as open every night even when
we were sure they'd all been gone for hours. Now when we check the all
the volumes late in the evening, they've been showing no files open.
perhaps that is a clue to a problem in lock tracking.
- While still at OES2 sp2, the pilot team kept giving vague
descriptions of problems using ACAD against files on OES2, but those
all went away after applying SP3, so after 2 months of one small group
running ACAD against files stored on OES2-linux, we migrated the bulk
of the data as the last volume from a failing NetWare 6.5.8 cluster
(recreating SBDs was getting tiring).

Glad to hear that your (and our) customer's life became less complicated.
Keep up doing the good work !
Best regards
Hans
Hi Hans,
i have just helped a customer to migrate their data from NW65SP8 to OES2SP3 and hit the same problem with the CAD group using AutoCAD 2004 on Windows XP with NC491SP3 + some Postpatches
Do we have a release date for the next OES2 SP3 Scheduled Maintenace Patch?
The last available is from May and has been apparently released the 31st of May.
Do we have a chance to get the ftf in someway?
Many thanks in advance and best regards,

Problem with default file access permission

Hi,
I am accessing a common area '/NFS_DATA' by both my java and oracle codes by the users 'javaUsr' and 'oraUsr' respectively.
As per the requirement, the oracle code (oraUsr) needs to create some file in the specified location and then the java code (javaUsr) needs to update those files (created by oraUsr) with some new data.
At present scenario the 'oraUsr' creates files with default access permission 644, which does not permit 'javaUsr' to update them.
Constraints : I am not supposed to set umask at the .profile of 'oraUsr'.
Execution of any shell script from oracle procedure is not permitted.
Is it possible to specify file-system specific default file access permissions??
Any idea to overcome this issue??

Any idea to overcome this issue??You might like to try using File ACLs
man setfacl(1)
as oraUsr
setfacl -s user:oraUsr:rw-,user:javaUsr:rwx,group::r--,other:---,mask:rwx file
This way the oraUsr can not execute file
but javausr can
getfacl will show the ACL
user::rw-
user:javaUsr:rwx #effective:rwx
group::rw- #effective:rw-
mask:rwx
other:---
hope this helps a bit
