Hello, first of all tank to both of you for your fast response. Going back to Michael's wonderful ASCII art masterpiece, what we have now is something like this:
------- JVM ----------- ---- JAVA ---- JDBC | | Algorithm | ---- JAVA ---- ------- JVM ----------- | RNI | R What we want is something like the following (on the same virtual machine): ------- JVM1 ----------- ------- JVM2 ----------- ---- JAVA ---- ---- JAVA ---- JDBC JDBC | | | | Algorithm Algorithm | | ---- JAVA ---- ---- JAVA ---- ------- JVM1 ----------- ------- JVM2 ----------- | | RNI RNI | | R(1) R(2) My question is: is that possible ? How can I address R(1) from JVM1 and R(2) from JVM2 ? Is data calculated in R(1) and R(2) completely independent or the 2 instances "share" something in memory ? Thanks again for you kindness and help. Angelo -----Messaggio originale----- Da: Oliver Ruebenacker [mailto:cur...@gmail.com] Inviato: venerdì 15 giugno 2012 17.36 A: R.

I think he means driving the R framework from Java via JNI. I think the questions boils down to whether you can open multiple independent R sessions on the same system and then address them separately via JNI (I don't know, but I would assume you can do that without multiplying the installation).
