Ice 3.1 client with an Ice 3.0.1 server?

bartley

Should I be able to use a client using Ice 3.1 with a server using Ice 3.0.1? I'm getting this error when I try:

CommandLineClient.exe: Ice.OperationNotExistException: OperationNotExistException
    id.name = "router"
    id.category = "TerkGlacier"
    facet = ""
    operation = "addProxies"

The server is using Ice for Java 3.0.1 (and Glacier). The client is written in C#, using Ice 3.1.0. I searched the docs for both Ice versions and see a few references to addProxies() in the 3.1 docs. But it appears to be called within the Ice core somewhere. Is there a workaround, or am I doing something wrong?

thanks,

Hi,

Due to interface changes in Ice 3.1 it is not possible to use a 3.1 client with a 3.0.1 Glacier2 server. The reverse will work though, a 3.0.1 client with a 3.1 Glacier2 server.
