B4J Question Jar (B4J) or as a webapp on ipad ...

B4J jars can only run on desktops. I do hope that in the future B4J will support web apps (or web servers).
Note that such apps run on the server. The client connects to the server with a browser.

The future is bleak for java web apps - increasingly apps will be useless unless they have some form of 'official' signature.

That's an official java update due anytime this month.

Unless your java web app comes 'officially signed' you'll see not a single user.
'Officially signed' sounds like a costly business to me - sorry for being cynical.

I'm sure the potential user can disable such stupid signature requirement on their computer should they wish.
But why make it impossible to simply create what is an old fashioned applet to run in a browser without so much bullsh#t?

Martin.

I didn't mean Java applets. As I wrote myself in other threads java applets are not relevant anymore.

I was referring to the ability to write web servers.
