I realized a report that uses a sub report with iReport tool, if I execute it works fine with iReport. but if put in my web application (JEE) this error myself out there
Check which version jasperreports.jar you are using..I got the same.I was using i-report 4.1.3 and jar file 3.7.0.Now i switch to jasperreports.4.1.3 and issue is resolved.
hello,
thank you for your answer, the problem is solved.
I spent iReport3.7.1 to iReport3.7.2, but when I copied the JAR iReport3.7.2 in the lib / directory of my project I have not removed the JAR iReport3.7.1.
I found the two JAR in this directory: that's the problem.
