iReport not starting using JRE 8
Solution 1:
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.
Solution 2:
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 <dir> 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...
Solution 3:
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"
Solution 4:
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.
