Non-GPL JNI

Non-GPL JNI

[dp]

Hello

I am aware of the JNI from Adacore. But it is unfortunately GPL licensed.
Are there any non-GPL alternatives?

Regards

The last known non GPL virused JNI packages (via wayback machine):

You might consider hand coding is not that difficult.

It shouldn't be too difficult to write a replacement interfaces.java
package set with tools to scan a jar and build bindings from Java classes.
Apparent they're fairly easy to reverse an interface from. There are papers
detailing how to map Java constructs onto Ada ones, these papers were
written by people in adacore and are public.

Does someone have a small example how to do it?
Just a Java function that calls an Ada function and vice-versa.

I do not need something that build bindings from Java classes.

If you are not familiar enough with how to recode the various C examples on the net directly in Ada, I'd suggest a very simple solution. Write the needed interface code in C and then just call Ada or have Ada call the C. if you are not using an Ada main, make sure to call adainit/adafinal to initialize the Ada runtime.
