RMI and in memory table

I'm building a distributed application that must perform the following issues:
a. a database query is executed and its result is saved into a DataSet that must be kept in memory
b. this dataset is sent then to the client using a session bean (stateful)
c. the client performs changes on this dataset (add, edit, insert records). The dataset must be able to launch events when the client does some operation
d. the client returns the modified dataset to the Session bean
e. in the session bean the changes are recognized (modified,added,deleted records/fields)
f. save dataset's changes into the database
g. keep the changes state if the client crashes
The environment/tools used to make this are:
1. JBuilder4
2. Inprise Application Server 4.1
My problem is that I have to choose the best component/structure that fits best to these requirements (specially in-memory storing and event detection). I've found some problems using Borland's TableDataset and DataSetdata trying to achieve this.
Could you give me any suggestions?
Thanks in advance

"mirko b",
The Java Ranch has thousands of visitors every week, many with surprisingly similar names. To avoid confusion we have a naming convention, described at http://www.javaranch.com/name.jsp. We require names to have at least two words, separated by a space, and strongly recommend that you use your full real name. Please log in with a new name which meets the requirements.
Thanks.


Best Regards,<br />Matt Midcap
