Hi I am a newbie to R and I would like to ask a few questions about RServ Java API... My problem is, there will be many callers use my client web service (it uses the rosuda Rengine API) to connect to RServ (running on linux), instead of each caller establish a new connection, I would want to let client to connect the RServ by "session" within the connection, how can I achieve this? 1 - Is there any example/way/recommendation on how to maintain the RConnection so that it is persistence? 2 - How session works in the API, I can see Rconnection.detach and Rsession.attach , the desciption of Rconnection.detach says "detaches the session and closes the connection" is confusing me, why it would cause the Rconnection to close...?
