Description: This article is the first in a two-part series that will concentrate on the resource adapter modifications and enhancements, with special focus on the new system-level contracts, particularly the lifecycle management and work management contracts. I'll cover implementation details and specification requirements, and we'll examine some pseudo-code to see how an EIS vendor might implement the new contracts for a version 1.5-compliant resource adapter. Part Two of this series (coming soon) will concentrate on the transaction inflow and message inflow contracts.
