Thank you very much Paul. I read the article you reffered and it contains the information I requested. Your help is very much appreciated.
When further looking at this matter, I found that there is a webapp folder in Jasper sample applications. Its coming with the Jasper installation package.
If someone is looking for the answer to j2ee-jasper integration, that webapp sample directory's path is jasperreports-1.2.3\demo\samples\webapp.
Thanks,
