Re: [jwt-dev] Using OWLAPI from within the handler of a plugin menu command

Hi Samir,

it seems to me that you missed to include the OWL API library file in the plugin definition. When the compiler tells you a ClassNotFoundException, then the path to the library is unknown. In the plugin.xml or MANIFEST.MF(which both opens the same dialog) you can find the libraries that should be taken into account during build. Add the OWLAPI.lib file (or the whole path) there and it should work. Please have a look into the same files in the Sempa-repositories which you probably should have already access to.

Good luck and best regards,

Dear All,

Has anyone managed to load an Ontology or generally using the OWLAPI from within the handler of a plugin menu COMMAND. I can do that from a normal class with a main method but I face an exception when I try doing it from within the execute method  of the command handler. The exception is a class not found exception and it doesn't make sense because I use the same code on another NORMAL class (with a main method) in the same package of the same plugin project and it works perfectly. I was wondering if anyone has ever faced something like that ?? will appreciate any suggestions.

Thanks in advance,
