Re: Java Persistence Architectures

[Henri Yandell <bayard@generationjava.com>]

Hibernate [hibernate.sf.net] is another. It's become the main challenger
to OJB in the OSS OR/Mapping area. TopLink is the commercial one I hear
the most, but I imagine most commercial things are going J2EE.

I'm not sure how easy OJB/Hibernate are to use without J2EE [ie) JDBC
extensions like DataSource and JNDI, although at least JNDI is in J2SE1.4
I think]. Are you confusing J2EE with EJB? [sorry, got to ask the
question, just in case].

Another is Castor JDO [www.exolab.org? i think]
