java.lang.Object

org.wildfly.extension.rts.jaxrs.ImportWildflyClientGlobalTransactionFilter

All Implemented Interfaces:

javax.ws.rs.container.ContainerRequestFilter, javax.ws.rs.container.ContainerResponseFilter

@Provider
 @Priority(value=4920)
public class ImportWildflyClientGlobalTransactionFilter
extends Object
implements javax.ws.rs.container.ContainerRequestFilter, javax.ws.rs.container.ContainerResponseFilter

Request and response filter which is expected to be called for the request side after the InboundBridgeFilter is processed while on the response side before the InboundBridgeFilter is processed.

Purpose of this filter is an integration of WFTC with Narayana REST-AT Inbound Bridge. Inbound Bridge uses Narayana transactions while WFLY utilizes WFTC transactions (wrapping the underlaying Narayana) ones. For that on request side the Inbound bridge first creates the Narayana transaction and then the request filter makes the WFTC to wrap and to know about this transaction. On the response side the WFTC needs to suspend its wrapping transaction and then Narayana suspend its own transaction (which was already suspended by WFTC callback and thus is ignored on the Narayana side).

The InboundBridgeFilter defines its Priority as Priorities#USER-100. This WildFly filter has to be processed after the Narayana one and it needs to define higher priority.
