How would I open the existing xsl file in JSP page or java?

I have done like this, but I don't see the contents of the ATR.xls. This file is located in C: drive.



response.setContentType("application/vnd.ms-excel");
response.setHeader("Content-disposition","attachment; filename= c:\\ATR.xls");


Can anyone tell what is the wrong in this code please?

Thanks

Hi Lakshmi,

The response.setHeader(..) doesn't do what you think it does. It does not attach the file to your response. It merely gives a name to your response.
You can read more about this here.

So additionally, you will have to read the excel file content, and stream that content to your response.

Best to do it with a Servlet. A jsp will add additional content to your stream - and that spoils the output.

Regards, Jan

(There is a separate JSP and Servlets forum on the Ranch)

Why? This makes your task significantly harder. Is there a reason for the JSP only requirement?

Hi,

I have gone through this program.
CODE]

try{
String ROOT_PATH = "C:\\tomcat\\webapps\\SnetReport\\REPORT\\"; FileInputStream in = new FileInputStream(ROOT_PATH + sFilename);
response.setContentType("application/xls"); response.setHeader("Content-Disposition", "attachment;filename=\"Report.xls\"");

int i; while ((i=in.read()) != -1)
{ out.write(i); }
in.close();
out.close();}catch(Exception e)

System.out.println("...error while loading: "+e.toString());}
[/CODE]

In the above code what is the sFileName
 
It is sorta covered in the JavaRanch Style Guide.
