Thanks for this. Retry is definitely important and the approach sounds =
good
but I'd probably rather we don't delay 1.1 final, so long as this can be
retrofitted without breaking anything.

I guess a couple of days delay would be OK, but I get nervous about =
putting
it in at the last minute...

Andy, J=FCrgen,

I've been away for the last week so sorry for the late reply.

Attached are some files that add retry support to all the standard =
Spring
remoting methods. The support is not as complete as my own remoting
implementation but for most cases should work fine. There's also some =
code
to allow metadata to be attached to RemoteInvocations (I think this =
stuff
only works for the RMI and HTTP remoting).=20

J=FCrgen would you consider adding this code? The retry support could
integrated higher up the class hierarchy perhaps as a subclass of
RemoteAccessor?

Following is an example config.

Client:
    <bean id=3D"theManager"
class=3D"org.springframework.remoting.support.RertyingClientProxyFactoryB=
ean">
        <property name=3D"wrapedRemoteAccessor"><ref =
local=3D"theManagerTarget"
/></property>
        <property name=3D"retryDecisionManager"><ref
local=3D"retryDecisionManager" /></property>       =20
    </bean>

    <bean id=3D"theManagerTarget"
class=3D"org.springframework.remoting.httpinvoker.HttpInvokerClientInterc=
eptor
