checking file extensions

[gisler]

Hi,

The code i have made i believe should check for a certain file extension and then send it out the socket.

    public void run() {
        Server sv = new Server();
        File folder = new File(sv.getFilePath());
        File[] listOfFiles = folder.listFiles();

        out.println(listOfFiles.length);
        for (int i = 0; i < listOfFiles.length; i++) {
            if (listOfFiles[i].isFile()) {                                //make sure its a file
                String fileName = listOfFiles[i].getName();     //put file name into string
                int pos = fileName.lastIndexOf(".");              //find the pos of the . in the filename
                String ext = fileName.substring(pos + 1);      // get extention name and place into string ext
                if (ext.equals("jpg") )                                //check the file extension is a jpg file type
                {
                    out.println(fileName);      //send filename to client
                }
            }
        }
    }

if i remove the "if statement" where it checks for the file type it runs fine only with every file type in that directory being sent to the client. Netbeans does not show any errors at all either.

thanks

Possible spellings of a "jpg" extension can be:
"jpg", "jpeg", "JPG", and "JPEG"
Try lowercasing the ext and testing for both spellings.

how would that matter since i am simply comparing what is in my ext string to the string "jpg". Wouldn't it just simply output nothing if the spelling was wrong?
Also i have stepped through the program. There is 8 jpg files and 1 desktop.ini file. The if statement does compare the extensions successfully. however the client program freezes unless i remove the

if (ext.equals("jpg") )

from my server thread.

When the program gets to the end of my run() method it then starts a thread called Thread.java[r/o]. If i am looking at my variables as well it gives me an error saying "Variable information not available, source compiled without -g option]"

Not sure if any of that is of any help. Hope that all makes sense

many thanks

I managed to solve the problem. The problem was because i was sending out more items than what the client was expecting to recieve.

Thanks for the help hardwired.
