Setting a Different Java Location

When installing a newer version of Java on your machine it will, by default, point the java command on the system %PATH% to the new version being installed. However, if you have multiple copies of Java installed or you use a non-standard way of installing java then it is possible to configure Xpress Insight client and server to use Java from a specific path.

Note: The paths should be added to the locations in question without quotes, even if they have spaces in them.

The location of the Java Runtime is stored in a number of places in Xpress Insight:

Under registry key HKEY_LOCAL_MACHINE\SOFTWARE\FICO Xpress, in the value JavaHome, as REG_SZ string data. (If absent, or an empty string, the default Java will be used.)

To configure Xpress Insight Server to use a specific Java install edit the following file in a text editor:

<installdir>/insight/server/wildfly-x.y.x/bin/standalone.conf.bat

where x.y.z represents the version, subversion, and patch numbers. Update the line which sets JAVA_HOME to contain the location to your custom Java install, (or set it to be blank to use the default Java) for example:

set JAVA_HOME=D:\apps\jdk11

Alternatively, if reverting to the default Java:

set JAVA_HOME=

You will need to restart your Xpress Insight Server to pick up the change.

In addition, if the Xpress Insight Server is installed as a Windows Service, you will need to update the Windows Registry relating to the Xpress Insight Server. The Xpress Insight Server should be stopped while this update is taking place:

• Under the Registry key HKEY_LOCAL_MACHNE\SYSTEM\CurrentControlSet\Services\FICO Xpress Insight Server, create or update the value named Environment as a REG_MULTI_SZ multi-line string value.
• In this value, add or update a line JAVA_HOME=<path_to_java>.
• If using the default Java, the line should simply read JAVA_HOME=.
