Damian,
I don't know if you have read the ND release
on the migration, but the official party
line is to write your applications to the
J2EE standard.
I am facing a similar situation, and we
decided that the application would be
basically a rewrite regardless of what
standards we adhered to. We are placing
chunks of business logic in EJB's such that
theoretically they can be reused. However,
we realized that by forsaking the use of the
spider classes we would not get the
advantages of ND.
If the event model of ND is gone, then the
front-end of the application must be re-
created. This in turn affects how you use
the business logic. Since we don't know
what iPlanet is going to be like (from an
IDE perspective), i.e. will there be an
event model that gives you a hook to the
equivalent of a 'onSubmit' event, we decided
to take advantage of the here & now powers
of ND.
Regarding your migration to ND5 first: The
major issues in the ND5 migration will
center around the change from C++ database
access to JDBC access. No further spider
changes are made, to my knowledge. There
are still a lot of issues with the JDBC
access (Oracle 'no columns' and synonm
issues come to mind), but for the most part
these can be worked around. ND5 will be
supported for at least 2 years (more if you
consider the first release of iPlanet has a
ND5 app. server built in) and I believe the
general consensus is that ND5 is a superior
product to ND4 (better performance, IDE
improvements, etc...).
I know this clears nothing up. It may have
even muddled my waters more. I just thought
you might like to know our decision points.
