I installed the client version iReport-5.5.1, then I configured jdk7 and set the jdkhome variable parameter (ireport.conf) pointing to the path jdkhome="/ usr / lib / jvm / jdk1 .7.0_80 /".
When I run iReport-5.6.0 / bin $ ./ireport does not open the client, after several searches, I did not succeed. Below is my settings.
