I have
been using Castor for a while now. Initially I choose Castor over OJB
simply because of its XML support. However, I am again evaluating OJB as a
replacement for Castor because we have done nothing with Castor-XML to
date.
In
terms of RDBMS persistence capibilities, in my opinion, OJB has an edge over
Castor. It is already ODMG compliant, and work is already under way for a
JDO compliant interface (and XML data binding is planned). So as a "pro",
my guess is that OJB will be the first open source project with a JDO-compliant
implementation.
If you
absolutely need XML data binding capability, Castor is the only choice (between
these two) for now. Although another thought I am planning on researching
is mapping persistence using OJB and mapping XML binding using Castor on the
same objects simultaneously (although this would lead to having to maintain two
seperate sets of mapping files).

Subject: Re: [castor-dev] JDO Performance Issue ... Again
If you know objectbridge and castor, could you tell me what made you go for castor over objectbridge? We are in the process of "evaluating" different implementations so any comments on pro and cons on castor/objectbridge/others would be much appreciated.
Do someone know of a site that has compared some of the different implementations Castor/jdo/odmg?

We didn't experienced performance problems yet, perhaps because we don't have more than one or two collections in a class and if more, these collections have a very small size (less than 10 elements or even empty). I think there is no active development on the JDO part currently. Perhaps someone from exolab could give a comment on this? An alternative would perhaps be: http://objectbridge.sourceforge.net/ These project seems to be more active.
