Well, I requested that you post the code, not the design. The design is fine, so there is obviously a problem with your code. I tried this: public void...
Hi Ian, I am sorry for the misunderstanding. I forgot one "magic" word: range. What I mean is that I can't obtain the properties whose range consist of union...
Hello Linair, Thanks for the clear example of what you are trying to do. I understand the issue now. You are quite correct: a property whose domain is a union...
Hi Andie, thanks for your advice. Many things seem more clear now. Although the commands -set JOSEKIROOT and set CLASSPATH- work, I cannot run Joseki from...
