Mac OS-X 10.8 or later (Leopard, Snow Leopard, Lion, Mountain Lion, Mavericks & Yosemite, Sierra High-Sierra & Mojave

jemsMacOSX install pakage (jemsMacOSX.pkg.zip) contains a fully configured java VM (jre 1.8.0_152). Download jemsMacOSX.pkg.zip, unzip it and install the application in /Applications (administrator rights needed). It is no more required to download java provided by Apple.

Note concerning Java extensions

In case you would like to use your own JRE, have the ".jar" files listed (Figure 2) placed in /Library/Java/Extensions. Without these archive files put in /Library/Java/Extensions it is not possible to send the jems license code request and to run java3D. These ".jar" files can be found in jemsMacOSX application, folder /Contents/Resources/jemsMac/jems/jar.

Windows  (version 4.7031u2018) (you may need administrator rights to complete the installation).

Ready to run version for Windows 7, 8, 10,  32 bits or 64 bits, available (jemsWindows7.zip) with jre 1.8.0_152. Unzip it, copy it to /Program Files(x86) 32 bits or /Program File (64 bits) and make the whole folder tree read/write. These versions are started using jems32.bat (32 bits OS) or jems64.bat (64 bits OS). In case of  trouble starting the java VM send a copy of the messages displayed in the Windows console. After selecting the 32 or 64 bit javaXX.bat rename it jems.bat.

Note for Windows users:

Java3D uses opengl libraries. Opengl is not supported by default on Windows. Check your documentation to add opengl support (you will have to get the ogl drivers from your graphics board manufacturer, i.e. ATI, NVIDIA, etc).

When moving jems folder tree to \Program Files it is necessary to make the whole jems folder tree read/write for all users. Open the folder properties, go to Security tab and allow all users to "Modify" the jems folder tree. Apply and close the security tab and set the read/write attributes to the whole jems folder tree.




Linux (Ubuntu 15.10  or later version 4.7031u2018) 64 bits with jre 1.8u152

A ready to use Linux version that includes javaVM  jre1.8u152 with supports for java3D opengl, java advanced imaging, javamail is available here (jemsLinux64.tar.gz). Copy & unzip, make it read/write and start it using jemsLinux.sh.

Note for Linux users:

Java3D uses opengl libraries. Opengl is, to my knowledge not always included in the Linux distribution. Check your documentation to add opengl support (you will have to get the ogl drivers from your graphics board manufacturer, i.e. ATI, NVIDIA, etc). Note that you may have to modify jemsLinux.sh in order to allocate more (or less) VM memory. See installation instructions.
