Switch To Java 11 on Synology and QNAP

Reconfigure LogicalDOC to use Java 11 on Synology and QNAP
Starting from version 8.3.4 LogicalDOC does not work with Java8 anymore so you have to install Java11.

It is important to install Java11 and not Java12 nor Java13, because Java11 is the latest LTS(Long Term Support) release available at the moment.

Given  the installation path of LogicalDOC(by default it is /share/CACHEDEV1_DATA/.qpkg/LogicalDOC/ in QNAP and /var/packages/LogicalDOC/target/ in Synology), please proceed as follows:

1. Open a SSH shell into your NAS as admin the cd to 

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

3. Execute the command tomcat8w.exe //MS/LogicalDOC  (if you do not have tomcat8w.exe use LogicalDOCw.exe instead)

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-11.0.4\bin\server)

8. In the Java Options text area, delete what you have and put this new text (remember to replace  with your LogicalDOC’s installation folder):

-Dcatalina.home=\tomcat

-Dcatalina.base=\tomcat

-Dignore.endorsed.dirs=\tomcat\endorsed

-Djava.io.tmpdir=\tomcat\temp

-Djava.util.logging.manager=org.apache.juli.ClassLoaderLogManager

-Djava.util.logging.config.file=\tomcat\conf\logging.properties

-Dsolr.disable.shardsWhitelist=true

9. Clear the Java 9 Options

10. Click on Apply and then Ok

11. Restart the LogicalDOC service

12. Open a shell as Administator and go to \update-wd

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

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

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

16. Now open the Java tab

17. In the Java Virtual Machine put the full path of your jvm.dll (something like C:\Program Files\Java\jdk-11.0.4\bin\server)

18. Click on Apply and then Ok

19. Restart the LogicalDOC Update service
