Factpluplus and Protege 5.6.0

[thistlillo]

Downloaded and installed Windows version (.exe) of Protege 5.6.0.

I installed the factpluplus plugin the first time I ran Protege 5.6, the file uk.ac.manchester.cs.owl.factplusplus-1.6.5.jar is indeed in the plugin subfolder.

However, the reasoner does not appear among the list of reasoners in the "Reasoner" menu

Could you open Protégé and have a look at the log window (menu Window > Show log…, or the button on the bottom right corner of the main window)? Then Look for any error message related to Fact++ (or post the log here).

I was curious if any headway had been made with this issue. My log posts the following related error message, including subsequent messages too:

The problem is that the last release of the Fact++ plugin happened several years ago, and the latest version of Windows the plugin declares to support is Windows 8, so it cannot be loaded on a machine running Windows 10 or 11. This is not something we can fix in Protégé, sorry. It’s in the hands of Fact++ developers, if they are still around.

It is possible to force the plugin to accept Windows 10 (and possibly 11, but I didn’t try) by crudely editing its manifest:

Go to Protégé’s plugins directory and use the jar command to extract the plugin’s manifest (you’ll need a Java Development Kit installed to get the jar command):

jar -x -f uk.ac.manchester.cs.owl.factplusplus-P5.x-v1.6.5.jar META-INF/MANIFEST.MF

Edit the META-INF/MANIFEST.MF file and add two lines to declare support for Windows 10:

 osname=Windows8 ;
 osname=Windows 8 ;
 osname=Windows8.1 ;
 osname=Windows 8.1 ;
 osname=Windows10 ;   <- Add this line
 osname=Windows 10 ;  <- And this one
 processor=x86_64 ;
 processor = amd64 ,
 lib/native/32bit/FaCTPlusPlusJNI.dll;

then use the jar command again to inject the tweaked manifest back into the plugin file:

jar -u -m META-INF/MANIFEST.MF -f uk.ac.manchester.cs.owl.factplusplus-P5.x-v1.6.5.jar

The plugin should then accept to load under Windows 10.

I have the another problems,

These are warnings, not errors. The modified Jar file should work despite such warnings.
