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\jdk1.8.0_201

or, 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=
