Transactions are necessary for many distributed applications to deliver reasonable results. Typically, said transaction engines enhance system dependability by providing atomicity, consistency, isolation, and durability. Yet, emerging paradigms in distributed systems seem to challenge these traditional concepts. This paper presents early results in integrating distributed object transactions with content-based publish/subscribe systems. Essentially, the paper illustrates a novel and generic integration framework that 1) supports application-dependent message failure models and 2) exhibits a full messaging transaction mechanism. We discuss integration challenges, analyze middleware requirements, and position our attempt among existing approaches.
