Question: ireport is not working with java 8?
Answer: The culprit is Java 8 as iReport is not compatible with Java 8 run time - well at least version 3.7. 6 is not. To resolve this issue, simply install the Java 7 JDK (unless already installed) on the machine on which iReport is installed and then configure iReport to use the JDK rather than your local JRE.
