File not found exception, snippet works flawlessly in other projects

Question

This following scippet works well, and I have been using it across many projects. However, for this one project, I get a file not found exception.

try {
        FileInputStream is = new FileInputStream(file);
        String original = file.getName();

        Logger.debug("Filename in upload pf %s ", original);
        IOUtils.copy(is, new FileOutputStream(Play.getFile(original)));

        PfParser p1 = new PfParser();
        p1.read(original, month, year);

        Payroll.index();

    } catch (FileNotFoundException e) {
        Logger.error(e, "Exception in uploadSheet: ");
        e.printStackTrace();
    } catch (IOException e) {
        Logger.error(e, "Exception in uploadSheet: ");
        e.printStackTrace();
    }

This is the read method, where I have tried a few combinations, which are commented out:

FileInputStream myInput = new FileInputStream(
                System.getProperty("user.dir") + inputFile);
        w = Workbook.getWorkbook(myInput);
        // w = Workbook.getWorkbook(new File(inputFile));
        // w = Workbook.getWorkbook(new File(System.getProperty("user.dir"),
        // inputFile));

This uploads the file to the C:\Program Files (x86)\Apache Software Foundation\Tomcat 6.0\webapps\ROOT\WEB-INF\application folder.

I am trying to read an excel file using Jexcel. The error I get on my server:

java.io.FileNotFoundException: foo.xls (The system cannot find the file specified)
    at java.io.FileInputStream.open(Native Method)
    at java.io.FileInputStream.<init>(Unknown Source)
    at java.io.FileInputStream.<init>(Unknown Source)

Trying the other (commented out) lines, only gives a variation in the error.

java.io.FileNotFoundException: C:\Program Files (x86)\Apache Software Foundation\Tomcat 6.0\foo.xls (The system cannot find the file specified)

I understand its a problem related with absolute and relative paths, but cant seem to find a solution. I do not get any errors, while coding and testing on my local machine which is Ubuntu. Its only when I deploy to a Windows server, do I get these problems.

Thanks.

Also googled a lot, and solutions on vogella also were not helpful. — theTuxRacer, Sep 24 '12 at 06:36

The FileNotFound exception come when the file is not located on the absolute/relative paths that you provide in your FileInputStream constructor.

FileInputStream is = new FileInputStream(file);

I doubt you are not giving the right location in your FileInputStream constructor. It would be good if you write the complete spinet including file location etc.

The file is successfully uploaded to `C:\Program Files (x86)\Apache Software Foundation\Tomcat 6.0\webapps\ROOT\WEB-INF\application` – theTuxRacer Sep 24 '12 at 06:55
Just the name of the file, without any path. – theTuxRacer Sep 24 '12 at 07:03
It could be the variation/change in the `System.getProperty("user.dir")` which may be different in the **Ubuntu** and **Windows** Platform. – KAS Sep 24 '12 at 07:10
Also please take care about the File System of both platform. As **"/"** is used on UNIX and **"\"** on Windows to refer the files. – KAS Sep 24 '12 at 07:18
I read on SO, that Java File methods manage the separators path very well. – theTuxRacer Sep 24 '12 at 07:21

I changed the line from

IOUtils.copy(is, new FileOutputStream(Play.getFile(original)));

to

IOUtils.copy(is, new FileOutputStream("./" + original));

Upload now works.
