On Linux, creating FileHandler for mounted directory hangs ....
Hi,
On Linux, I try to create a FileHandler for a mounted directory and it hangs. Anyone knows why, please let me know.
Here is the code that I use. Suprisingly, it works for Windows for mounted directory.
public class NewFileHandle
{
public static void main (String[] args)
{
try
{
System.out.println("Before");
FileHandler custlogFileHandler = new FileHandler("/var/tmp/logs/custlog", true);
System.out.println("After");
}
catch (Exception e)
{
e.printStackTrace();
}
}
}
Regards,

Sounds like the file is locked for write access. The FileHandler constructor probably won't return until the file is unlocked. Can you make FileHandler open the file read-only (won't work if custlog is locked exclusively, but that usually it's just a simple write lock)? Just guessing, mind you...

Hi Brian,
The file is not locked. Actually file does not exist there. This class should create a "custlog" file.
I also tried creating a file myself and changing the permissions to "777". But still it did not work.
When I run the same program for local directory, it works fine.
Is this a bug in java? I tried searching the bugs database, but could not find it.
Here is what I tried.
1) File does not exist at the given location:
root@base0-0-0-6-0-11-1:/opt/hss/log> export PATH=$PATH:/usr/local/java/jre1.5.0_04/bin/:
root@base0-0-0-6-0-11-1:/opt/hss/log> which java
/usr/local/java/jre1.5.0_04/bin/java
root@base0-0-0-6-0-11-1:/opt/hss/log> java NewFileHandle
Before
......... hangs here ...
2) File exist with "777" permissions
root@base0-0-0-6-0-11-1:/opt/hss> ls -l custlog
-rw-r--r-- 1 root root 0 Aug 31 09:46 custlog
root@base0-0-0-6-0-11-1:/opt/hss> chmod 777 custlog
root@base0-0-0-6-0-11-1:/opt/hss> cd log/
root@base0-0-0-6-0-11-1:/opt/hss/log> java NewFileHandle
root@base0-0-0-6-0-11-1:/opt/hss/log> java NewFileHandle
Before
......hangs here ....
