HI
I am a new comers &
I create this servlet to generate PDF & HTML of a .rptdesing file
named
user_reg_report.rptdesign.Now my probleam is -when i save this rptdesign
as .PDF & put in
" C://jakarta-tomcat-5.0.27/webapps/learnity/report/test11.rpt design" then
it is ok. But when i create only rptdesign not .PDF then my servlet
doesnot generate PDF/HTML.
This is my source code. Please reply me.
