Subject RE: Updating DataMap through ROP client
Date Mon, 16 Feb 2009 04:48:07 GMT
I have solved the DataMap problem with the following: I have created an
HTTP back-channel that send the map xmls to the client. The client then
creates a new Configuration instance, modifies the data maps, serializes
the results to XML, sends them to the server and the server saves them
to disk. The remaining problems to solve are the following:

1) I need to somehow refresh the configuration instances that are in
memory for the HessianServlet.
2) Once refreshed, I need to somehow clear the object caches of the
HessianServlet. 

All of this without dropping any connections that the HessianServlet is
servicing.

Hi Zissis,

DbEntities are not being sent to client (and DataMap is sent trimmed).
So I
don't think you can perform DataMap changes from client. What I would
try to
do is to write a custom query which performs your operations and the
fire it
from the client. I'm not sure this will work though.

Regards,
Andrey
