Hi folks,
I apologize in advance if this �beginner type� post is out of scope for
this list,
but I'm in search of some candid EJB advice. I've been reading Tom
Valesky's EJB
Book, Oracles EJB related doc�s and the J2EE doc's, and I�m still left
pondering
how to best design my system.
I want provide a service for a client (an EJB being developed on another
project)
by allowing the client to �register� for this service. Essentially
registering for the
service is adding a record to a database table. Another process would
monitor
the table, and perform the service on the data it finds in the table and
send the
results back to the client. The service is actually taking the
registered
information and querying another database for some results to be sent to
the client
application.
There is only one client application (and I dicate the interface), but
potentially thousands of entries in the registry table (the service
would run hourly). The database being queried will have several hundred
million records and pretty much represents my domain object model for
the overall application.
Could I do all of this with Session Beans? I�m pretty sure a Session
Bean would
work great for the service part, but what about for doing the
registering part, the
actual database �inserts� and �removes� when the clients wants to
de-register?
I was originally planning on managing the domain database with EB's.
Even I did get an EJB server that supported EB's, would EB's be a viable
option and what would I gain by using that over just using servlets and
java stored procedures?
I�ve read through a lot of the list archive entries the last couple
days, so I anticipate
some feedback as to other EJB servers to use. But I can�t spend any
money on another EJB Server. Can I use the j2ee server for anything
other than testing? Also, is Jonas a viable option for an EJB Server?
Thank in advance for any advice,
Rob
