Me too. My system is:

OS: Ubuntu Linux 14.04
IReport 5.6.0
Java 1.8.0_11-b12

The missing class seem to have something to do with the netbeen ide environment.
I hope we don't have install netbean to run the thing.

That's simple because JasperReports still does not support JDK 8.

It appears the NetBeans has been hit with the same problems with respect to JDK8/openide being incompatable.
See Bug 229191 - Cannot start NetBeans on JDK8 because ISE occurs

The problem got a P1 Priority in NetBeans. Any clues as how to make the same fix in iReport. Is it just a matter of getting a new openide jar from netbeans?

  • Resolution:Reopened» Won't Fix

Development of iReports has already ended and Jaspersoft has encouraged users to switched to Jaspersoft Studio.
FYI, Jaspersoft Studio does work with JDK8.


1.- install JDK 1.7,
2.- Change this line


into {IREPORT_HOME}\etc\ireport.conf

for this:


for example:

jdkhome="C:\Archivos de programa\Java\jdk1.7.0_71\jre"

(Don't forget delete sharp caracter)

setting the jdkhome to jdk1.7 works great

I have install ireport 5.6.0 When starting a logo appear and then disappear. irport is not starting. What should I do.


Hi Nad436, iReport development has been stopped in favor of Jaspersoft Studio several years ago. Anyway, I assume iReport may not work with java 1.8, but the problem may also be different. In your home directory you should find an ide log which may tell you what the problem is (something like <user home>/ireport/var/log.
You may also want to try to run iReport from the command line in order to have some kind of output.

Thank you
