I googled it and it is multitasking so technically one can run two web apps side by side.

I also found this to start the web app at synology nas boot (don't shoot the messenger - I do not own a synology nas yet but checking around for possible implementations - there might be an easier solution of doing this):

Scroll down to the autostart section:

Synology installation and troubleshooting

Yes I noticed that with the code in the link in post#21. I wasn't aware of it though when I asked the question.

Make sure that you has already installed Java8.

In your folder "/volume1/web/webapp/HelloWorld" you have to copy both "WebAppHelloWorld.jar" and the "www" folder from your project in B4J.

Then you have to make it running on NAS: go in "Panel Control -> Task Scheduler" -> click on "Create" button -> "Triggered Task -> User-defined script" or "Scheduled Task > User-defined script" (depends on your necessity: try with "Triggered Task" at "Boot-up", user "root"). Remember to select "Enable".

Put the code with your path:
B4X: 
cd /volume1/web/webapp/HelloWorld
nohup /var/packages/Java8/target/j2sdk-image/bin/java -jar /volume1/web/webapp/HelloWorld/WebAppHelloWorld.jar > /volume1/web/webapp/HelloWorld/nohup.out
don't forget the first line!

Click on "Run" button or restart the NAS.

I think that you should manage more than one task and server but not on the same port.

You must copy the entire www folder as it is in B4j objects folder.

Connect to the NAS with SSH and try the commands in the command line to see what’s happening before adding the line to the NAS script

0K.. I am going to try right now

EDIT:
Putty says: "-sh: /volume1/web/webapp/HelloWorld/nohup.out: No such file or directory"
No idea what is happening

EDIT2: (problems with uppercase)
Putty says: "nohup: ignoring input and redirecting stderr to stdout"
nohup.out says: "Error: Unable to access jarfile volume1/web/webapp/helloworld/WebAppHelloWorld.jar"
