I have tried to install GraphDB free 9.0.0 on a Windows 10 laptop (x64). The installation finishes succesfully but when I double click GraphDB it does not run. What should I check in order to fiind out why it does not run?
Thank you
I install GDB regularly on Windows 10 using the installer (eg GraphDB_Free-9.3.0.exe). It comes bundled with Java. Here's the version:
cd C:\Users\vladimir.alexiev.000\AppData\Local\GraphDB Free\runtime\bin
java --version
openjdk 11.0.7 2020-04-14
OpenJDK Runtime Environment AdoptOpenJDK (build 11.0.7+10)
OpenJDK 64-Bit Server VM AdoptOpenJDK (build 11.0.7+10, mixed mode)
It's convenient because after starting, it opens Workbench in your browser, and a small control panel where you can see the log etc, and a tray icon.
If you use one of the other distributions, check your Java version.

When I try to start up Cassandra DB under windows 10, It complains about the Java version:
Cassandra 3.0 and later require Java 8u40 or later.
I believe I have the latest Java installed:
java --version
java 13.0.2 2020-01-14
Java(TM) SE Runtime Environment (build 13.0.2+8)
Java HotSpot(TM) 64-Bit Server VM (build 13.0.2+8, mixed mode, sharing)
I've installed Apache Cassandra 3.11.9 (the open source version not the Datastax version).
Why doesn't Cassandra recognize this version of Java? Do I need to install a different version of Java to get this working?
Yes, you need to install Java 8 to run Cassandra 3.11 - it will not work with Java 13 (yes, I understand that error message isn't clear). Support for Java > 8 was added only to Cassandra 4.0, that is currently in beta.
Also, on Windows it would be easier to use Docker to run Cassandra - there are different difficulties with running Cassandra on Windows.
I'm trying to install Kafka 2.6.0 on a Red Hat VM. When I try to start Zookeeper, I get:
"Classpath is empty. Please build the project first..."
I have the following Java Version, which is Java 8 as far as I understand:
openjdk version "1.8.0_171"
OpenJDK Runtime Environment (build 1.8.0_171-b10)
OpenJDK 64-Bit Server VM (build 25.171-b10, mixed mode)
Is there something I need to do to set a "Classpath" environment variable?
I updated .bashrc for my users and the Classpath error went away.

I have the following installed on Ubuntu 18.04.1 LTS:
openjdk version "10.0.2" 2018-07-17
OpenJDK Runtime Environment (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.1)
OpenJDK 64-Bit Server VM (build 10.0.2+13-Ubuntu-1ubuntu0.18.04.1, mixed mode)
javafx.runtime.version=8.0.161
javafx.runtime.build=b00
However I try to run the sample java application that uses javafx I get the following error:
$ java -jar Untitled.jar
Error: JavaFX runtime components are missing, and are required to run this application
I have tried to run it in Eclipse, Intelli, and in the terminal with the same error.
I have set the classpath
:~$ echo $CLASSPATH
/usr/share/java/openjfx/jre/lib/ext/jfxrt.jar:.
I have copied all of the javafx files to the current directory.
I have tried everything I can find on the internet.
Does anyone know how to fix this?
On Ubuntu 18.04 with openjdk-11-jre and openjfx installed you could use:
% java --module-path /usr/share/openjfx/lib --add-modules ALL-MODULE-PATH \
-jar Untitled.jar
There is more information on how to run JavaFX programs at the openjfx.io site.

Any ideas?
Look at solution on this answer
Uninstall google-talkplugin. This work for me.
I run KDE as well and I've added this to eclipse.ini
after vmargs :
-Dorg.eclipse.swt.browser.DefaultType=mozilla
And it solved my problem
here's my system specs;
Arch Linux x86_64,
Kernel: 3.6.10-1-ARCH,
Gnome 3.6.2,
xf86-video-nouveau 1.0.4-1,
jdk7-openjdk 7.u9_2.3.3-1,
jre7-openjdk 7.u9_2.3.3-1,
jre7-openjdk-headless 7.u9_2.3.3-1,
lib32-libjpeg-turbo 1.2.1-1, libjpeg-turbo 1.2.1-1, libjpeg6-turbo 1.2.1-1
libpng12 1.2.50-2,
net-tools 1.60.20120804git-2,
unzip 6.0-6.
Ok, so there's the list of requirements that are installed, version numbers as well. Upon launch, the loading/splash screen won't even show, and then nothing... it just dies out. I attempted to launch it "aptana -v" and no output in the shell. I have looked for any error logs in ~/ , but nothing is there.
Other steps I've done is to delete any configuration folders/files for eclipse and aptana-secure in ~/. Also did a clean uninstall of just Aptana (not the dependencies), reinstall. Same result.
Any suggestions?
It appears that there is a mix up in the downloads. 32-bit and 64-bit got switched. If you are on 32-bit download 64-bit and vice versa. Hopefully it will be fixed soon.
See issues below:
