Reconfigure LogicalDOC to use Java 21 on Windows

Starting from version 9.0.1 LogicalDOC does not work with Java 17 anymore so you have to install Java 21. Please read first how to install the right Java to use with LogicalDOC.

It is important to install Java 21 and not Java 22 nor Java 23, because Java21 is the latest LTS (Long Term Support) release available at the moment.

Given <LDOC_HOME> the installation path of LogicalDOC (by default it is C:\LogicalDOC), please proceed as follows:

1. Install Java21 from Oracle or OpenJDK21

2. Open a shell as Administator and go to <LDOC_HOME>\tomcat\bin\

3. Execute the command LogicalDOCw.exe //MS/LogicalDOC

4. This creates a tray icon with the LogicalDOC’s logo

5. Right click on it and choose Configure...

8. Click on Apply and then Ok

9. Restart the LogicalDOC service

10. Open a shell as Administator and go to <LDOC_HOME>\update-wd

11. Execute the command 'update-wdw.exe //MS/LogicalDOC-Update

12. This creates another tray icon with the LogicalDOC’s logo
