Hi,all In my application,I use Derby to store datas. There is an error sometimes happens during the application running. "ERROR - An SQL data change is not permitted for a read-only connection, user or database." It seems that the derby user has no enough privilege to write datas.But I am sure the account running the application is Administrator,and the application runs well most of time ,so I think the privilege is not the reason of the error. And the other cause I guess is that there is no enough disk space,so the derby can't write datas from memory to disk.But I can't check the computer runs the application now. So I need your help to tell me if any other reasons can lead into this error?
Thank you!
