1.) Please use code tags when posting code.
2.) Access denied is a security issue. Do you have rights to the file you are trying to access?

[eyeofsoul]

of course.what makes that things happens..i am really confused..

Which of the lines is line 111 in the code? The problem seems to be there somewhere...

[Nepomuk]

So the relevant line 111 is
[CODE=java]
out = new BufferedOutputS tream(new FileOutputStrea m(outFile));
[/CODE]right? Make sure, that you're not trying to write information to a folder - that will not be allowed. If outFile is a folder, change that and try again.

If you want to copy a file called test.zip to the myFolder directory, then your destination path should be
/myFolder/test.zip not just /myFolder.

That's what's wrong with your code. You basically need to get the file name (including extension) and append that to the destination path.

[eyeofsoul]

okay..i think i got the idea..but how do i combine the destination path with the real name of the file that want to be copied?

[Nepomuk]

okay..i think i got the idea..but how do i combine the destination path with the real name of the file that want to be copied?

You can get the original file name with
[CODE=java]
inFile.getName( )
[/CODE]Use it, when setting the path to the new file.

You read the source file's path and then use the getName method of the File class.
There are quite a few useful methods and fields in that File class that you can make use of as well.

[CODE=java]
inFile.getName( )

You're awefully fast today.

[eyeofsoul]

as i mention in the code.the file that want to be copied is in browse button and the dir button is in the other "if".hope you understand.i cant write clearly.

[r035198x]

i got a problem here.

String s = "\";

unclosed string literal.
i dont understand this.i want to declare s as "\" but the line were underline saying unclosed string literal.

Check the API for the File class like I said. You may find that there is no need to declare a string with that value at all.

To make it work you would need to escape it because it's a special character so you can do
[CODE=java]String slash = "\\";[/CODE]

as you can see.the destination path is in file2.how do i get the file.getName() in the first if to be called in the second if?

Get the destination File's path using some method in the File class (you really need to open the page for that class) and then append the name of the file you want to put there. You may need to include a file separator (also available in the file class)
