problem of FILE

[hugsdan]

hi all,

i want to know if a file exists, here is my code :

------------------------
File dd = new File("G:/SQL.LOG");
boolean f = dd.isFile();
out.println("dan = " + f);
------------------------------
(the file sql.log exists)
i can see :" dan = true"

that's logic

but when i change the code:

------------------------------
File dd = new File("G:/act_tma/test.log");
out.println(rep_tableau + nom_tableau);
boolean f = dd.isFile();
out.println("dan = " + f);
-----------------------------
(the file test.log exists)
i can see: "dan = false"

what is not logic...

have you an idea???

PS : G:/ is connected to a network

[hugsdan]

it's the same thing if i put the method exists() instead of isFile()

why???

f.exists() verify if the file indicated by this path exists and
f.isFile() verify if the file exists and is a norma file (is not a directory and satisfy other conditions which dependts of your system)
See Java API documentation

[hugsdan]

the path exists but when i use the method exists(), it returns always false...

[Cristian2003]

normal I mean (I ate an "l")
I don't really know what exactly means "normal file" but I think that a "system file" is not a regular file for example. I hope I don't mistake !

I think beacause this file with ".log" extension isn't a regular file ...

[hugsdan]

when i use a .xls, it's the same thing...

[Cristian2003]

Sorry I was wrong, but I think this is a network problem ...

[Cristian2003]

try for the same files but local, on your machine

[hugsdan]

it works on local
but it works also on the root of G: which is on the network...

[Cristian2003]

Maybe you don't have sufficient rights to those files on the network

[hugsdan]

but i can open those files "manually"

[Cristian2003]

Yes, but in order to access them from an Java programme I think you should have full acces to the path where "they" are.

[hugsdan]

do you know a method to copy it on the local machine?
perhaps with 'cp' of MSDOS console?

[Cristian2003]

copy source destination (for MS-DOS)
Ctrl+C and Ctrl+V in your destination path .... (other OS)
