RE: extents and mapping inheritence
I was looking at the DescriptorRepository class and I feel I could easily patch it to walk the inheritance tree for "invisible" mappings via inheritance. I will patch it if this functionality desired. *===* * Scott T Weaver * * Jakarta Jetspeed Portal Project * * [EMAIL PROTECTED] * *===* > -Original Message- > From: Leandro Rodrigo Saad Cruz [mailto:[EMAIL PROTECTED] > Sent: Tuesday, June 24, 2003 7:28 AM > To: OJB Users List > Subject: Re: extents and mapping inheritence > > I have inherence working for collection descriptors.

RE: extents and mapping inheritence
OJB will be the default persistence model within Jetspeed 2 and all my current posts have been spawned by my implementing of OJB in Jetspeed 2. I recently converted the entire object model from Castor to OJB (still in progress). So, you will probably be seeing more posts from me in the near future;) *===* * Scott T Weaver * * Jakarta Jetspeed Portal Project * * [EMAIL PROTECTED] * *===* > -Original Message- > From: Thomas Mahler [mailto:[EMAIL PROTECTED] > Sent: Tuesday, June 24, 2003 1:47 AM > To: OJB Users List > Subject: Re: extents and mapping inheritence > > Hi Scott, > > Weaver, Scott wrote: > > Is there anyway I can remove the mapping for B entirely.

Hi Scott, Weaver, Scott wrote: Is there anyway I can remove the mapping for B entirely. It implements the interface AB and extends A. That should be good enough for OJB. However, when I try this, I get class B is not persistence capable. The reason I want to do this is B is a special case that may or may not be used and we would prefer to keep it out of the OJB mappings and rely entirely on dealing with AB and/or A. If you are using B instances you *must* provide a class-descriptor for B. OJB prints out the message you see when you try to call persistence operations on aclass that is not defined in the repository. Scott, I have one question regarding Jetspeed.

Is there anyway I can remove the mapping for B entirely. It implements the interface AB and extends A. That should be good enough for OJB. However, when I try this, I get class B is not persistence capable.
