Export to Excel as .xls file from JSP

[chaitanya83]

Hello,
I'm trying to export my results to .xls file. The following is the code which I have in my .jsp:

String fileName="SID";
fileName=fileNa me+".xls";
String contentType = "applicatio n/vnd.ms-excel";
response.setHea der("Content-disposition", "attachment ; filename=" + fileName);
response.setCon tentType(conten tType);

Results are getting downloaded to excel,but I have few attributes which contains more than 10 digits...in this case ,value is coming in exponential form instead of numeric.
I have to get in numeric form..

eg:-4.17823E+11 instead of 417822805897

Please do the needful.

Thanks,
Chaitanya
