Switch to Java21 on Windows

Starting from version 9.0.1 LogicalDOC does not work with Java17 anymore so you have to install Java21. Please read first how to install the right Java to use with LogicalDOC.

It is important to install Java21 and not Java22 nor Java23, 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:

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...

6. Now open the Java tab

7. In the Java Virtual Machine put the full path of your jvm.dll (something like C:\Program Files\Java\jdk-21\bin\server)

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

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

14. Now open the Java tab

15. In the Java Virtual Machine put the full path of your jvm.dll (something like C:\Program Files\Java\jdk-21\bin\server)

16. Click on Apply and then Ok
