A method and a corresponding system for managing communication between multiple instances contained within a clustered environment. The method includes generating a packet to be transmitted from a non-Java-based server node to a Java-based server node. The non-Java-based server node specifies in a header of the packet [1] a destination server node and [2] information to indicate that the packet originated from the non-Java-based server node. The method further includes forwarding the packet from the non-Java-based server node to an intermediate server. Once the intermediate server receives the packet, the intermediate server examines the header of the packet and forwards the packet to the Java-based server node based on the destination information provided in the header of the packet.
