Hi All,

I am using windows 7 and trying to create a file .testBoringFile on my mounted drive "U:".
I wrote following code.

File tempfile = new File("U:\\sandbox\\.testBoringFile"); try{ if (tempfile.exists()) { tempfile.delete(); } if (tempfile.createNewFile()) { } }catch(Exception e){ e.printStackTrace(); }

.testBoringFile gets creates but an exception is thrown while executing"tempFile.createNewFile()".

java.io.IOException: The process cannot access the file because another process has locked a portion of the file at java.io.WinNTFileSystem.createFileExclusively(Native Method) at java.io.File.createNewFile(Unknown Source)


I referred following link, but doesn't get any useful info. http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4857780


Can anyone please help me out?

Hi All,

I got the solution from my friend...It should look like as -
String[] cmds = {"cmd.exe" ,"/c","%windir%\\Sysnative\\cmd.exe" ,"/c", "mount.exe server2:/d/jaibhim z:"}

hi Maneesh,

its mount not mountvol.

mount.exe is present under C:\Windows\system32


Thanks,

Hi All,

I am using windows 7. If I run following command from command prompt
> mount server2:/d/jaibhim z:
It mounts the network drive /d/jaibhim on my z: drive.

I want to achieve same result through Java. So I wrote following piece of code-
String array[] = { "C:\\Windows\\System32\\cmd.exe", "/C", "C:\\Windows\\System32\\mount.exe", "server2:/d/jaibhim z:" }; Process proc = Runtime.getRuntime().exec(array); proc.waitFor(); String outputString = ""; BufferedReader returnInputStream = new BufferedReader( new InputStreamReader(proc.getErrorStream())); List<String> usedDriveList = new ArrayList<String>(); while ((outputString = returnInputStream.readLine()) != null) { System.out.println(outputString); }

I get following error from the error stream- "'C:\Windows\System32\mount.exe' is not recognized as an internal or external command,"

Could you please guide me, where I am going wrong?


Thanks,

Hi All,

I am opening one channel and reading some streams through a socket. If i use setSoTimeout(5000), it is expected that socket will be closed after 5 seconds.
Consider, I have established SSH connection with a server and reading data through socket, I want to know -
1. If my operation through that socket is taking 20 seconds, will that socket will be timed out after 5 seconds even if the operation is in progress?
2. If my connection breaks with the server when it is reading data through that socket, will my socket be timed out after 5 seconds?

Hi Experts,

I have created a java swing application which has help button. When user presses the help button, I launch the native web browser in which help url is provided and opened.
Now, I m thinking to copy those help html files and pack it inside the executable jar file. I am able to create the jar with the help html files packed in the jar. Now, I want to open these packed html files when user presses the help button.

Can anyone please guide me to open the packed html file inside the jar?

I want to allow only one instance to be running of my jar...So, I am checking for the process, if that process is already running then I will pop-out the error message to user stating that , "another instance of Myjar.jar is running"

Hi Rob,

Thanks for the info, but I cant expect my application users to install "Process explorer". Is there any another way?

Hi All,

I have one executable jar e.g. "MyJar.jar". When I run this jar on linux machine, I am able to figure it out that this jar is running or not as-
ps -ef | grep MyJar.jar

But when I run this jar on windows, then I see only java.exe as running process.

Is there a way by which I can identify on windows whether MyJar.jar is running or not?


Thanks,

I have designed one Java application in which I have provided a button. On pressing that button, following method is invoked and mail window is opened in ms-outlook on widows. But it throws exception on ubuntu thunderbird.

public static void onLaunchMail(java.awt.event.ActionEvent evt) {// GEN-FIRST:event_onLaunchMail String mailTo = "user@domain.com"; URI uriMailTo = null; try { if (mailTo.length() >0) { uriMailTo = new URI("mailto", mailTo, null); desktop.mail(uriMailTo); } else { desktop.mail(); } } catch (IOException ioe) { ioe.printStackTrace(); } catch (URISyntaxException use) { use.printStackTrace(); } }

Exception is ----

everything works fine on windows but fails on ubuntu. Any pointers to this problem?

Hi Dan,

what I have observed after running "top" command that my all "svn" processes got stuck in "pipewr" state. If I would be able to take out my svn processes from "pipewr" state then everything will work fine.

Regards,
jai

the svn command that I m executing is -
svn co https://jai.com/src/1 --username jaibhim --password xxxxxx

Whats the modification required?

Thanks Dan, I will try it out...

Hi Dan,

Thanks for the pointer.... commandToSVNCheckout() has svn command to co a directory and nothing else....
Could you please explain " i used "start svn checkout xxx" for having different window running", I did not understand it completely.


Thanks,
jai

Hi Dan,

I create 10 threads in similar fashion as follows....
Thread t1 = new Thread(new Threader1());
t.start();

and run() is as follows-

run(){

commandToSVNCheckout()

}
