    Help with clustered MBeans

    michael.daleiden

      I've read (and re-read) the Clustering doco and cannot fathom how to set things up so that the following scenario works:

      I have a set of MBeans that provide services for my application. I would like to deploy these MBeans on multiple servers (for load-balancing and failover). I do not want to set them up as singletons, but I do want one and only one MBean to be utilized per request (e.g., no callMethodOnCluster()). I also would like to have the invocations of the MBeans load-balanced (any flavor is fine) and fault-tolerant (so that if a server goes down, the invocation of the service is routed to another server).

      I am thinking that there is a way to do this using HARMI, but I can't seem to wrap my brain around what to do on the server side to set up HARMI for each of the MBeans, and I also can't fathom how to set up the client (application) side to use HARMI.

      It is important to note that I cannot use EJBs for the implementation of these services, as they are very multi-threaded. I could use EJBs to front-end the MBeans on each server, but I was wondering if there is another mechanism that might eliminate the need for EJBs.

      Any and all help is appreciated!

          yes, you could programatically achieve what you describe but I highly suggest you use SLSB to front end your solution as this will make things much easier for you (at least before 4.0) and easier to configure as well as everything is already there.
