opening an xls file from the database in jsf

I have been given the task of opening xls files in the browser using jsf and oracle, these files are stored in the database.
How do I accomplish this?

Thanks,
Sonia

Step 1 : Load the data to a object of type List
Step 2 : Iterate the list of the object and write the data corresponding to the excel file...
Step 3 : upload the data..

Code Snippet...

String fileName = "excelFileName";

// Create a new work book
HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet("mySheet1");
........
..........
........

for (SlectedObjectTO : objectList)
{
HSSFRow rows = sheet.createRow(j);

..........
........

}

// Writing data to the output stream.
FacesContext context = FacesContext.getCurrentInstance();
HttpServletResponse response = (HttpServletResponse) FacesContext.getCurrentInstance().getExternalContext()
.getResponse();
response.setHeader("Content-disposition", "attachment;filename=" + fileName + ".xls");
response.setContentType("application/vnd.ms-excel");
log.debug("Response contect :: " + response.getContentType());
ServletOutputStream out;

try
{
out = response.getOutputStream();
wb.write(out);
out.flush();
out.close();
}

Required API :: POI

Hi,

I downloaded the poi libraries and put it in eclipse classpath and in the WEB-INF/lib directory.
But I am getting a ClassNotFoundException: org.apache.poi.usermodel.HSSFWorkBook.

Thanks,

Hi,

May be configuration is not correct.
or More than one poi.jar is referred.

Hi,

I got it to work. But it looks like all the examples produce an excel file. But they don't open in a swing application for editing. or in the browser. Is there such an example?

Thanks,

Sonia

I am writing a jsf application in which when the user selects a file it is pulled from the database. I want to be able to open the xls file in swing or in the browser. I need an example to do that.
They need to be able to edit and save the xls file.

Thanks,

Sonia

In the previous scenerio when the execl file is populated it will have 3 buttons saying open, save and close
user can click on open and edit the deatils and save.

I will let you know, once i find the solution

Somebody from the apache mailing list has suggested a Servlet. Trying to figure out how
to map a servlet into a jsf application.
