Hi,
I think I've found the reason for my jaxb problems which was in the client stub code and not related to synapse anyhow. The mediator that I'm writing should catch all the incoming messages and do some validation to them, but the validation part requires that it (mediator) calls other web service for some details used in validation. So it would be a blocking call and that callout mediator you mentioned sounds just what I need, I'll take a look at it. Thanks for help!
