How can I download files from tomcat to my computer?
you can use WinSCP
or something similar to connect to the host that is running your Tomcat
I want to code a button so I can download it from tomcat
Use ExportDisplay object in one of your application’s screens.
A small example here: Downloading Files - CUBA Platform. Developer’s Manual
Is there any way to download via url link?
Add LinkButton to the screen: LinkButton - CUBA Platform. Developer’s Manual
and handle downloading logic in its invoke handler.
This component looks like a url link.
