[protege-discussion] protege database - Error

[Ganesh kumar]

Hi All,

I am trying to using protege (V3.4.8) with a database backend.
I have created a protege project of type "protege database".

I face the following errors/issues

1)When I try to create classes or instance or anything, I get an error in
the console (see below for the error) [And this is a new project and it
does not have any other user data with it]
2)Does protege support the data to be loaded back from a database ?

Your help will be much appreciated.
