ArtiSynth Installation Guide for Linux

4 Installing Java

ArtiSynth requires that you have a full Java development kit (JDK) installed, which comes with a Java compiler; a simple run time environment (JRE) will not be sufficient. By default, ArtiSynth is compiled to be compliant with Java 8. While ArtiSynth will generally work under later Java versions, there have been occasional reports of compatibility issues involving the Java OpenGL (JOGL) interface. Therefore we currently recommend using Java 8; this also provides maximum compatibility with MATLAB, as indicated above. We specifically recommend the Java SE Development Kit 8uXXX (where XXX is the latest revision number), which can be obtained from Oracle (registration required). At the time of this writing, the download page is located at

and the latest release is 8u281. This page provides downloads for all systems; be sure to choose the download link appropriate to yours.

If the above Oracle link is no longer current, the search terms ``java 8 jdk download'' should get you to the right place.

4.1 Ensuring the JDK is visible to your system

After the JDK has been installed, it is important to ensure that it is visible to your system and that it supersedes any other Java installations. One test for this is to open a terminal window and run the command

 > javac -version

The output should match the version of the installed JDK. If it does not, or if the command javac is not found, then one fix is to add the directory <JDK_HOME>/bin to your system Path, as described in Section 13.1, where <JDK_HOME> is the JDK installation directory. In particular, <JDK_HOME>/bin should be added ahead of any other Java installations that might be specified on the Path. To see the current contents of the Path, open a terminal window and run the command

 > echo $PATH
