Is Java 1.8 is compatible with BO4.0 SP9? When I am trying to open the BI launchpad - "Cannot launch Java report panel, please make sure you have installed Java Virtual Machine" error is displaying,
In BO server jre1.8_111 and JDK 1.8_111 are installed
Please advice
According to the PAM, BI4.0 is supported with JRE 6-8.
Few things to note:
The version of the JRE/JDK on the server is irrelevant. A JRE must be installed on the client in order to use the WebI Java panel.
The bitness of the JRE must match the browser. If you are using 64-bit IE, then you will need a 64-bit JRE.
Newer versions of Chrome and (I believe) Firefox do not support Java at all.

I am trying to start NetBeans 8.2 on a Macbook Pro and it's not working.
It shows the splash screen, then after a while it shuts down without starting anything.
Running from the command-line I can see this error:
Oct 02, 2017 7:40:28 PM org.netbeans.ProxyURLStreamHandlerFactory register

Looks like Java 9 got bundled with it and it's causing an error. The documentation implies that NetBeans 8.2 uses JDK 8!?
How to use my own java to run NetBeans, or how to get NetBeans to start without this error?
Yes, NetBeans 8.2 does use JDK 1.8, and specifically does not support JDK 1.9.
It's unclear from the OP which version of Java is desired to run with NetBeans, but the version of NetBeans to use is governed by the version of Java to be used:
[1] For Java 8, use Netbeans 8.2. Note that Java 9 is not supported. You can download NetBeans 8.2 bundled with JDK 8u141 for Mac OS here:
http://www.oracle.com/technetwork/articles/javase/jdk-netbeans-jsp-142931.html
Once it has been installed it no specific configuration for Java should be necessary.
[2] For Java 9 you must use a Development Build of NetBeans. That can be downloaded from http://bits.netbeans.org/download/trunk/nightly/latest/ but be sure that Mac OS X is selected from the Platform drop list before clicking Download.
For any version of NetBeans you can specify your own version of Java as follows:
Start NetBeans and select Java Platforms from the Tools menu.
Click the Add Platform... button.
Complete the wizard to locate the version of Java you want to use.
One final point: there is no problem having multiple versions of NetBeans installed and running concurrently using different JDKs, typically NetBeans 8.2 with JDK 1.8 and NetBeans Dev Build with JDK 1.9.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Update:
If NetBeans closes itself down on startup it may have an invalid JDK path. To change the JDK that NetBeans uses:
Locate the file netbeans.conf. It should be in the etc directory under the NetBeans installation directory.
Edit that file in a text editor. Locate the line containing the property netbeans_jdkhome. On my Windows 10 installation it looks like this:
netbeans_jdkhome="C:\Java\jdk1.8.0_121"
Change the value for that property to specify the path to the desired JDK, save the file and restart NetBeans.
As pointed in the comments:
I had tried to set netbeans_jdkhome in /Applications/NetBeans/NetBeans\ 8.2.app/Contents/Resources/NetBeans/etc/netbeans.conf to point to JDK 10, but still it did not work.
I had to install JDK 8, and set netbeans_jdkhome="/Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home"
Uninstalling JDK 10 and using JDK 8 worked for me and setting netbeans_jdkhome="/Library/Java/JavaVirtualMachines/jdk1.8.0_181.jdk/Contents/Home" worked quite well.
macOS 10.13.5
JavaJDK 10 installed as "System" JVM
I was able to install NetBeans, but unable to get it to function. Window would open, clicking on "New Project" or "New File" did absolutely nothing.
Was able to get it working (all modules and servers) by going into the configuration file at
/Applications/NetBeans/NetBeans 8.2.app/Contents/Resources/NetBeans/etc/netbeans.conf
and editing the commented out path to JDK at the bottom of the file!
Cheers!
Check Java JDK is installed on Mac, NetBeans 8.2 does use JDK 1.8(Java SE 8)
/usr/libexec/java_home -V
Matching Java Virtual Machines (2):
12.0.1, x86_64: "Java SE 12.0.1" /Library/Java/JavaVirtualMachines/jdk-12.0.1.jdk/Contents/Home
1.8.0_211, x86_64: "Java SE 8" /Library/Java/JavaVirtualMachines/jdk1.8.0_211.jdk/Contents/Home
if not , just install (no need remove exist JDK)
https://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
modify /Applications/NetBeans/NetBeans 8.2.app/Contents/Resources/NetBeans/etc/netbeans.conf
netbeans_jdkhome="/Library/Java/JavaVirtualMachines/jdk1.8.0_211.jdk/Contents/Home"
For NetBeans 8.2 JDK 1.8 should be used. If you installed JDK 1.9 or JDK 10.0 to your MacBook, you must uninstall that from your computer.
I had the same issue. I'm using Apache Netbeans 12.0 so I had to change my OpenJDK version from 19.0 to 14.0 and update the path in order to finally work.
No need to uninstall the 19.0, just install the version that works with the Apache that you have and update the path:
netbeans_jdkhome="/Library/Java/JavaVirtualMachines/jdk14.0.jdk/Contents/Home"
For now it seems to be impossible the decouple the jre for the main application from the jre used by the installer/updater itself. But sometimes there is a reason to use two different jre/jdk. Maybe the application needs java 8 and the installer is built with java 7 or older. Or maybe there are two applications to install which use two different java versions. Another idea is to create some kind of a meta installer that decide during runtime whether to install 32bit or 64bit java depend on the underlying platform architecture? The installer itself then has to use a 32bit version. So what about to decouple it and configure the jre for the application launchers itself independend from the java version of the installer/updater?
Starting with version 6.1.2 the launcher wizard will have an option to configured the JRE search sequence differently from the installer.
The setting will be available under the "Java invocation->Override Java version" step.
Upon installing a new JRE in Eclipse 4.3 (on Mac OS X 10.8.4), I am given the following options:
Execution Environment Description
MacOS X VM
Standard 1.1.x VM
Standard VM
What's the difference between the final three options?
You have to choose Standard VM for a vanilla JRE or JDK.
MacOS X VM refers to the apple implementation that is bundled with OS X until now, Standard 1.1.x VM is a compatibility for legacy Java 1.1 and Standard VM is for Standard JRE from Sun/Oracle (Vanilla) .
From Eclipse documentation:
Standard VM - You will select a folder where the JRE is installed. The
details of the JRE will be determined by scanning the location. You
can further customize the JRE install, specifying vm arguments, source
attachments, etc.
Standard VM 1.x.x - Same options as a standard VM
install, but the install is customized to handle the 1.x.x install
Basically, the options here let you choose the JVM implementation. Standard 1.1.x refers to compatibility with Java 1.1. MacOS X VM here refers to Apple's implementation.
I have upgraded to Java7 recently.
I had my install4j Project file in Java6.
Now in the Install4j IDE, I go to Media wizard and download 1.7 JRE's and select them for Windows. (I have window 7 64 bit.)
But When I go the Installer tab in IDE , where for some of the screens I have my custom code which is compiled in Java7.
It gives an error for the IDE java version lower than the compiled version(for those class files).
The Common Location where is the JRE for 1.6 was downloaded C:\Program Files\Common Files\i4j_jres
But the JREs for 1.7 somehow are never downloaded in the common location.
How Do I make the Install4j IDE to upgrade to Java7 instead of Java6.
Thanks
Sony
We had the same problem as you, so we just swapped out install4j's built-in JRE with the one we used to compile our custom code.
i.e. - replace "C:\Program Files\install4j5\jre" with the jre you use to build your custom actions.
Under General Settings->Java version, change the minimum version to 1.7
I installed JBoss Tools on my Eclipse Juno. It worked, then when I click the tab design/view/ whatever it is except the source on my JSP window, It said that JBoss tool for JSP editor cannot run on my 64-bit Eclipse, JRE7, and Windows 7.
I've been browsing all over the place, some forums say you have to change your JRE to 32-bit. After that I installed JRE7 32-bit, restart and I tried to see the Java on Control Panel.
When I clicked Java tab on Control Panel, it said
Couldn't open \lib\i386\jvm.cfg.
I tried to checked on CMD, I typed java -version then it displayed
Unable to load native library: Can't load IA 32-bit.dll on AMD 64-bit platform.
I advise you to uninstall all Java instances, then start again.
Install 64-bit JDK first, set up your normal development tools to use it. Then install the 32-bit JDK but don't install the public JRE. Then configure a separate instance of Eclipse to use the 32-bit JDK. (I'd keep a separate, normal 64-bit Eclipse around, because 32-bit means you are limited to about 1.5Gb of heap for Java)
