[jboss-user] [EJB 3.0] - Re: Anyone have SINGLE_TABLE Entity inheritance working?

[lpmon]

As I suspected this did not work.  How would the container know the coulmn and the type to apply the discriminator value to if you omit the @DiscriminatorColumn?

It seems to be complaining about a property named "connected".  My entity has no such property?

I see many examples like what I am trying to do yet I cannot get mine to work.

If I leave out @DiscriminatorColumn

I get:
