I'm using protege 5.5.0 for Mac and I was trying to run reasoner to use DL query but every time when I started it I got the error message that I've attached with this email.
Could you please help me to solve this problem.
Thanks in advance,
Asking the same question, without providing additional information, multiple times on a mailing list will not help your situation.
Protege works for most people most of the time. When something bad happens, often it’s because issues or interaction with
1. the runtime environment: OS version, Java version, etc.
2. the specific ontology
3. possible customization you’ve made (i.e., plugins)
There may be bugs in Protege, but they are triggered by something. You had not provided sufficient information for anyone to help you. I suggested in an earlier message that you post your ontology so others can see whether they see the same problem.
