writing file to server

[Ciarrai]

Hi,
i am trying to empty the contents of an excel file into an excel spreadsheet - i'm using HSSF. It works fine when i'm testing it on tomcat on my local machine, but when I try to write to a folder on the web server it doesn't appear. The file path is absolute and I set the folder permissions to 777. Can anyone offer some ideas? Much obilged.


protected void doGet (HttpServletRequest req, HttpServletResponse res) throws ServletException, IOException
{
doPost(req,res);
}


protected void doPost (HttpServletRequest req, HttpServletResponse res)
throws ServletException, IOException {
res.setContentType("text/html");
PrintWriter out = res.getWriter();
try{
stmt = con.createStatement();
queryString15 = ("SELECT * from lastweeksheet ORDER BY date ASC");
rs2 = stmt.executeQuery(queryString15);
String results [][] = new String[3][2];

rs2.next();
for (int i=0;i<3;i++)
{
for (int j=0;j<2;j=j+1)
{
System.out.println("Nice!");
results[j] = rs2.getString(1);
j++;
results[j] = rs2.getString(2);
System.out.println("Done!");
}
rs2.next();
}
for (int i=0;i<3;i++)
{

for (int j=0;j<2;j=j+1)
{
day = results[j];
j++;
format = results[j];
queryString14 = ("SELECT * from "+day+" ORDER BY time ASC");
