FAQ

The version 1.4.1 of OCTOPUS is not compatible with Java >=9, this will be implemented in the next OCTOPUS release.

Meanwhile, if you need to keep your default java version to 9 or 10, you can copy and  unzip jre1.8.0_171_linux.zip for Linux or jre1.8.0_171_win.zip for Windows on your computer.

Then modify the java used by OCTOPUS in the octopus.bat (windows) or octopus.sh (linux)  file (in the installation directory).

replace java by <java_path>java where <java_path> is the path to the java 8 that you just copied, as in the exemple below:

<your_path_to_the_copied_java8/>java -jar octopus.jar

If you need to launch OCTOPUS on a server without a graphical interface (no graphical packages installed), use the command below:
java -cp octopus.jar fr.ifremer.octopus.controller.BatchController <options>

  • Error: "Could not find or load main class fr.ifremer.octopus.MainApp"
    • Check your version of Java: it must be java Oracle 1.8.0_131 minimum or openJDK 1.8.0_60 minimum with openJFX (both are mandatory)
  • Error : Exception in thread "main" java.lang.UnsupportedClassVersionError: fr/ifremer/octopus/MainApp : Unsupported major.minor version 52.0
    • Check your version of Java: it must be java Oracle 1.8.0_131 minimum

Download last version of Java

1/ In the octopus installation directory (containing the octopus.jar file): create a file named octopus.bat

2/ in this file, write the following line:

java -Dhttp.proxyHost=xx.xx.xx.xx -Dhttp.proxyPort=yy -jar octopus.jar

with xx.xx.xx.xx = your HTTP proxy server IP address, yy= your HTTP proxy port.

If you have a HTTPS proxy, you may use:

java -Dhttps.proxyHost=xx.xx.xx.xx -Dhttps.proxyPort=yy -jar octopus.jar

You can combine HTTP and HTTPS parameters if needed:

java -Dhttp.proxyHost=xx.xx.xx.xx -Dhttp.proxyPort=yy -Dhttps.proxyHost=aa.aa.aa.aa -Dhttps.proxyPort=bb -jar octopus.jar

3/ launch octopus using this octopus.bat file (double click)

For more information you can have a look to https://docs.oracle.com/javase/8/docs/technotes/guides/net/proxies.html

For the moment, there is no Mac OS Octopus version. But Octopus is a java application. (The .exe and .sh files for windows and linux are just shortcuts to simplify the user life.)

If the user has installed java Oracle 1.8 on his Mac OS, he should be able to run Octopus:

  • Download Octopus for linux
  • Launch the command below in a console: java -jar octopus.jar
