Re: Sending Messages and Sharing Objects

Hello Raju,

Can't understand about 2Tiers. Why don't use WS instead of remoting in your case?

It's the message-orient system, based on XML messages, as I described in the former post

I can't see what's wrong with Database solution? The data is consitend and located in one place. You can be sure that there is no variety of the same data. Keep on local? In client? It's possible, but you need additional steps to update this data between clients.


RJ> Any ideas or suggestions. Some one recommended I could create a

Yep, but it's too common.
There is a lot of solutions that u can apply.

Describe your problem more detailed

100 external users or intenal? Intranet or internet apps?

What do use for the messages XML and XSTL to transfer messages to the
canonical form?
I think remoting will tie you too hard, and it brings a lot of
problems
with indigo.
I recomend to use WS, it's gives u a nice heterogeneity.
What do u mean with "data cache"? Database or what?

Could u specify more details?

The general solution is that.
When patient comes to the consultation either he or operator create
new
record on the webSite with necessary information,
afterthat this record in converted(xslt) in the message (xml) that is
sent
to the server where the message is pushed into the ESB(enterprise
service
bus) and your rule engine decided with component is responsible for
this
message, and you message is parsed by that component. component takes
all
necessary data from DB and generate output message.
RJ> We are currently in the design phase of a distributed system. I
have

RJ> RJ> Our app will be used by 100s of users. I would like to send
