Re: propagate primary key and owns destination (Java Client and EOF)

Hi John (et al.),

Thanks for your reply to my post.

Thanks also for that tip, it is a good piece of information (which 
probably applies just as well to any use of EOF but even more so to JC 
EOF) to keep in mind.

Yes, this always amazes me, I have studied J2EE and MS.Net quite a bit, 
and can see no comparable technology to Java Client - and, I have even 
posted to this list asking for any pointers to such with no response.

I think a lot of developers and organisations are just awakening to the 
power of (standard) WebObjects as they understand the requirements of 
Enterprise applications better - unfortunately as Apple still seems 
reluctant to push it in any way, shape, or form.

I guess it is going to be a few more years until these same developers 
are looking for a way of doing "automatic" client-side distribution of 
business objects for client-side processing (with partitioning as a 
bonus), I only hope WebObjects and Java Client are still around at that 
time.

It worries me that you say JC is not working in 5.2.3, I have only used 
it for the simplest of demos (using Direct To Java Client), but I am 
considering it for a large Enterprise application, and would like some 
degree of confidence that it is not going away in (at least) the near 
term.

Can you elaborate on this please?

Cheers,
Ashley.
