java.io.FileNotFoundException: ..\log\server.log (Access is denied.

[parimal]

Hi friends,
I am getting problem while run following line:

f=new File(strFileExt);
out =new PrintStream(new BufferedOutputStream(new FileOutputStream(f,true)),true);

The error is as follows:
java.io.FileNotFoundException: ..\log\server.log (Access is denied.

)

at java.io.FileOutputStream.openAppend(Native Method)

at java.io.FileOutputStream.<init>(FileOutputStream.j ava:177)

at Test.ReadAndPrintXMLFile.main(ReadAndPrintXMLFile. java:86)


Please check out the problem

Thanks

Is the file Read only? Or does some other app have a lock on it?
What OS?

hi Norm,
I have checked what u mentiond all ok.
file is not read only
there is no locking
Os windows-2000

In your BufferedOutputStream the second argument is set to true. Why is that? It should be the buffer size you going to use, so it's an int type.

[parimal]

Dear Eranga,
I think you didn't check carefully,the second true for PrintStream to on utoflush

[rjuyal]

you might not have the permission to write/create a file.

[parimal]

Hi rjual,
I already checked by already created file to specified path and also have the permission to write to that.

[Norm]

Is the path correct? What is the value of strFileExt?
What is your current directory relative to the path?

[parimal]

Dear Norm,
I tried that by using by hardcoded path.
that doesn't work giving same error

FileNotFoundException - if the file exists but is a directory rather than a regular file, does not exist but cannot be created, or cannot be opened for any other reason

From the API doc.
What happens if you remove the append flag?
Or change the path/filename?

[parimal]

I tried all possible way like changing path or filename.
I think append flag is not matter of this problem

[Norm]

Have you tried it on other systems? Is there something about your environment that causes the problem?
Can you strip the code to a minimum (like 20 lines) and post it here for others to try?

Hi,

Use the file path as this: "c:\\temp\\myfolder\\abcd.txt"
We were having problem in one windows mahine in accessing file path when we used "c:\temp\myfolder\abcd.txt". Adding one extra slash after each solved the problems.

[jack239]

Also in UNIX you should use file patha as-
"var/www/myfolder/abcd.txt' and know what Unix is very case sensitive.

Here we get an exception, use of a single slash(back slash). Because once JVM find a back slash it looking for a escape sequence. But there may not found a valid escape sequence with a single slash. To add a single slash you have to use two back slashes as follows.

Code:

c:\\temp\\myfolder\\abcd.txt

In Java this is not a good practice at all. If you use this in a UNIX/Linux system it comes with a runtime exception. Because this pattern only valid in Windows systems. So the best way is the following in Java, since it's platform independent.

Code:

c:/temp/myfolder/abcd.txt

What you try to pointed here?

[parimal]

strFileExt="C:\\parimal\\log\\server.log";
try
{
File f=new File(strFileExt);
out =new PrintStream(new BufferedOutputStream(new FileOutputStream(f,true)),true);

System.setOut(out);
System.setErr(out);
}catch(Exception e)
{}

But still giving like:
java.io.FileNotFoundException: C:\parimal\log\server.log (Access is denied.

)

[mtv134]

which OS user runs the JVM?
this user has to have the appropriate permissions on the file and the read permissions on the directory containing the file.

I get this when the output file is flagged as R/O

[parimal]

Dear Norm,
The problem got resolved.
Actually while i am creating a file through the file i/o that creates a folder with extention .log which is read only
