Introduction

When you install the Directory Synchronization Client, you can choose whether or not to install the Java Runtime Environment (JRE).

You can install the JRE independently of the Directory Synchronization Client so that it is available to multiple applications. Alternatively, you can install a separate copy for each application on your system that requires a JRE.

The advantage of installing a JRE with each application is that if you remove or update the global JRE, your application does not stop working. The main disadvantage is that the JRE is several megabytes in size, and installing a copy for each application could consume disk space. We recommend installing the Directory Synchronization Client with its own JRE.

To check the current version of JRE in Windows, select Start > Control Panel > Java. Click About to display the version number.

To check the current version of JRE in Linux, go to the following Web site, which displays your Java version:
