Tomas, it seems you're looking at remote query over REST (via JSON). This has not been implemented yet but we might have it in 6.1.
In 6.0 we already have remote query over Hot Rod implemented (using protobuf encoding - much more compact than JSON). Some rough details available here: https://community.jboss.org/wiki/RemoteQueryDesignInInfinispan We did not go the bytecode generation of annotated classes route as you're probably trying to do. Instead we use a pretty nifty generic entity (ProtobufValueWrapper) and a HSearch class bridge (ProtobufValueWrapperFieldBridge) - all configured programatically, no annotations. Let's chat tomorrow on #infinispan and see how we may help you.
