The JIProlog IDE is working fine, thanks. It shows the correct licensing information, with my name and email address.
But when I try to embed it in an application - for example, the JIPSkeleton app, in Intellij - it displays the Shareware notice, as soon as the JIPEngine is instantiated.
What else should be activated, besides the IDE, and how?
Got it. I copied the .lic file to the project folder, and the shareware message disappeared.
Does this mean, that distributed applications, have to include a copy of the license.lic file?
