GroupWise 18


After upgrading from GroupWise 2014.x to GroupWise 18.x on Windows 2016 server, everything runs except the Admin Service. No errors are found in the adminservice log.

When attempting to run the gwadminutil.cmd program, the following error is returned:

<JAVA_HOME>/lib/ext exists, extensions mechanism no longer supported; Use -classpath instead.
.Error: Could not create the Java Virtual Machine.
Error: A fatal exception has occurred. Program will exit.


Both the Admin Service and gwadminutil should use the version of Java installed with the GroupWise Server and not the machine version.

Found the following directory that needed to be removed: D:\Groupwise\admin\jre\lib\ext

Once the ext folder was removed, both the Admin Service and gwadminutil worked correctly.
