Hi,everybody
Thanks for you arriving.I was a new developer in jasper.Today,i have a problem.First i use the ireport to generate a report, and it works.But when i put it to the javaEE project, it doesn't work.
Other project in my program is used well.So ,it shouldn't be the question of jar.Here is the error log.
