Tomcat creates 0 byte files

I have a very simple file upload mechanism in java. I just take the file and save it on the server. I'm testing this simple code with selenium and when a timeout occurs in the selenium test tomcat creates 0 byte files under tomcat_home/work/Catalina/localhost/uploadServlet/ directory as MultiPart* files. It creates thousands of files, until there is no disk space left on device. What may cause this problem? How can I solve this? Is there anyone has an idea about this?

My environment is: Ubuntu - 8.04 server, apache tomcat - 5.5.29, sun java 1.6

Thanks,

Here is the code snippet that i use

    String strFileName = request.getParameter("FileName");
    String strPath = request.getParameter("Path");
    File fFile = (File) request.getAttribute("Content");

    int index = strPath.length() - 1; 
    if (strPath.charAt(index) != '/') {
        strPath += "/";
    }
    if (! new File(strPath).exists()) {
        new File(strPath).mkdirs();
    }
    File file = new File(strPath + strFileName);
    FileOutputStream fileOutputStream = new FileOutputStream(file);
    FileInputStream fileInputStream = new FileInputStream(fFile);

    byte[]开发者_StackOverflow bBuf = new byte[1024];

    int iBufLen = 0;
    int iReadLen = 1024;
    int iTotelLen = 0;
    /*read 1024 bytes at a time*/
    while ((iBufLen = fileInputStream.read(bBuf)) != -1) {
        fileOutputStream.write(bBuf);
        fileOutputStream.flush();
        iTotelLen += iBufLen;
        if (fileInputStream.available() < iReadLen) {
            iReadLen = fileInputStream.available();
            break;
        }
    }

    byte[] tempbBuf = new byte[iReadLen];
    fileInputStream.read(tempbBuf, 0, iReadLen);

    fileOutputStream.write(tempbBuf);

    fileOutputStream.close();
    fileInputStream.close();

    if (fFile.exists()) {
        fFile.delete();
    }

I've used apache commons file upload class and i've deleted the temporary files in the finally section. The problem is solved with this implementation.

Is it possible that some sort of exception is occuring in the middle of this code? Best to close the streams in a finally block.
