Managing the Microsoft Java VM (MSJVM) with Ion

Applies to

Ion 2.x


Although the Microsoft Java VM (known as the MSJVM) has not been available since 1998, some organizations still use the MSJVM to run some of their internal applications. The MSJVM is another Java VM, just like Oracle/Sun’s Java VM. As such, by default, only one version of Java may be run inside of Internet Explorer at any one time. This presents a problem for organizations attempting to maintain security, as the MSJVM is over 10 years old and has includes security support or updates.


Ion allows organizations to manage the MSJVM in a similar manner to how they can manage multiple versions of the Oracle Java VM. Please refer to the PDF below.
