iReport does not work with java 8    if not yet installed  download and install java 7 find the install dir of your iReport and open the file  ireport conf    you will find it here  iReport-x x x etc     change this line    jdkhome   path to jdk    to this  if not this is your java 7 install dir then replace the parameter value between   s with your installed java 7 s path    jdkhome  C  Program Files Java jdk1 7 0 67

There s another way if you don t want to have older Java versions installed you can do the following   1  Download the iReport-5 6 0 zip from https   sourceforge net projects ireport files iReport iReport-5 6 0   2  Download jre-7u67-windows-x64 tar gz  the one packed in a tar  from https   www oracle com technetwork java javase downloads java-archive-downloads-javase7-521261 html  3  Extract the iReport and in the extracted folder that contains the bin and etc folders throw in the jre  For example if you unpack twice the jre-7u67-windows-x64 tar gz you end up with a folder named jre1 7 0 67  Put that folder in the iReport-5 6 0 directory     and then go into the etc folder and edit the file ireport conf and add the following line into it   For Windows jdkhome    jre1 7 0 67   For Linux jdkhome    jre1 7 0 67   Note   jre version may change  according to your download of 1 7    now if you run the ireport w exe from the bin folder in the iReport directory it should load just fine

While ireport does not officially support java8  there is a fairly simple way to make ireport  tested with ireport 5 1  work with Java 8   The problem is actually in netbeans   There is a very simple patch  assuming you don t care about the improved security in Java 8    http   hg netbeans org jet-main diff 3238e03c676f openide util src org openide util WeakListenerImpl java  I didn t even use the exact netbeans source used by ireport   I just downloaded the latest WeakListenerImpl java in full from the above repository  and compiled it in the ireport directory with platform9 lib org-openide-util jar in the compiler classpath  cd blah blah iReport-5 1 0 wget http   hg netbeans org jet-main raw-file 3238e03c676f openide util src org openide util WeakListenerImpl java javac -d   -cp platform9 lib org-openide-util jar WeakListenerImpl java zip -r platform9 lib org-openide-util jar org   I am avoiding running eclipse just to edit jasper reports as long as I can   The netbeans based ireport is so much lighter weight   Running Eclipse is like using emacs

don t uninstall anything   a system with multiple versions of java works just fine   and you don t need to update your environment varables  e g  java home  path  etc        yes  ireports 3 6 1 needs java 7  doesn t work with java 8      all you have to do is edit C  Program Files Jaspersoft iReport-nb-3 6 1 etc ireport conf     default location of JDK JRE  can be overridden by using --jdkhome  lt dir gt  switch jdkhome  C  Program Files Java jdk1 7 0 45    on linux  no spaces and standard file paths  its that much easier   keep your java 8 for other interesting projects

For me  the combination of Stuart Gathman s and Raviath s answer in this thread did the trick in Windows Server 2016 for iReport 5 6 0   In addition  I added a symlink within C  program files java jre7 to jdk8 like this   cmd  c mklink  d  C  program files java jre7 bin   C  Program Files Java jdk1 8 0 181 bin    because iReport was constantly complaining that it could not find java exe within C  program files java jre7 bin  - So I served it the available java exe  in my case V8 181  under the desired path and it swallowed it gladly
