B4J Question Start at startup raspberry

[jayel]

Hello,

I want to start my abmaterial app on startup of my raspberry.
Is there a way of doing this?
Put the command in rc.local?

Any help?

This question is not specific to ABMaterial. Better edit the title and remove the prefix.

Check this: https://www.b4x.com/android/forum/threads/run-b4j-app-at-startup-on-pi.72301/#content

Thx

 

[jayel]

Sorry but not working as expected.
Maybe ABmaterial problem afterall.
I does start automatic on startup but I keep getting the material waiting circle.
When I kill the service on the raspberry and run it with the sh command It does the job !

 

[jayel]

Strange, now not working anymore both ways !

Have you copied the .needs file too?

 

[jayel]

yes

Press F5, (refresh the cache). If on Chrome, press F12 and check the errors in the console. They may give you a clue.

My directorystructure :

is this right ?

because in my console I see :

??

Those errors look like you are missing the files in /css, /js and /fonts in the /www folder. You have to copy the whole /www folder manually over to the pi

 

[jayel]

These files are all copied, I tok a copy from my local www folder and copied it over, css is also copied, above 2 screenshots

looks ok to me, except on my system I see different rights and owner for the .gz files:

 

[alwaysbusy]

Maybe set chmod 777 on the kraanserver and all its subfolders.

 

[jayel]

Even when I set chmod 777 on kraanserver dir and all its subdirs it doesn't work....

I connected B4J with the bridge and run via B4J the solution and everything works smooth !
What am i doing wrong here?

Just a check if the KraanServer is running from a Raspberry Pi Terminal:
Login to the Raspberry Pi, open a terminal, set the kraanserver folder and start KraanServer.jar: (based on Post #9 folderinfo)

• cd home/pi/kraanserver
• sudo java -jar KraanServer.jar

Please ensure to use the right case to start the KraanServer!

I'm sorry I did not read all the posts.
I saw that the owner of some files is pi .
This can be a problem if pi did not have root rights.

you should apply the change (WinSCP -> Advanced button) that you can see in the screeshot to make sure that the files are copied as root

 

[jayel]

Even in rc.local it didn't work.
I erased all the files ans setup up the raspberry again.
Then I copied the files needed the run the webapp and put in rc.local the sh file.
Now everything run s OK !

Thanks everywone.

Another great help from this forum, tumbs up !
