Opening multiple excel files thorugh a servlet

Question

Hi
In my system , i have excel reports in my server disk . And i am opening the excel files through an servlet class like /viewReport.do?id=23 .....and thus from the servlet will open my excel file .
After opening one excel file , i try to open another excel by clicking that link , then my system often hangs else excel shows an error saying "a report with name viewReport.do is already open " even though both of these files are different on the server
How can i avoid this ??
The reason why i am opening the excel file through a servlet is , i need to perform some operations before opening that excel report
Can any one let me know how to go abt this ??

This is my code in servlet...
HSSFWorkbook wb = new HSSFWorkbook();
     HSSFSheet spreadSheet = wb.createSheet("Users");
     spreadSheet.setColumnWidth((short) 0, (short) (256 * 25));
     spreadSheet.setColumnWidth((short) 1, (short) (256 * 25));
//     Creating Rows
     HSSFRow row = spreadSheet.createRow(0);
     HSSFCell cell = row.createCell((short) 1);
     cell.setCellValue("Year 2005");
     cell = row.createCell((short) 2);
     cell.setCellValue("Year 2004");
     HSSFRow row1 = spreadSheet.createRow(1);
     HSSFCellStyle cellStyle = wb.createCellStyle();
cellStyle.setBorderRight(HSSFCellStyle.BORDER_MEDIUM);
cellStyle.setBorderTop(HSSFCellStyle.BORDER_MEDIUM);
cellStyle.setBorderLeft(HSSFCellStyle.BORDER_MEDIUM);
cellStyle.setBorderBottom(HSSFCellStyle.BORDER_MEDIUM);
cell = row1.createCell((short) 0);
