Welcome to our continuing coverage of asynchronous messaging and the new CORBA Messaging specification. Our previous column presented an overview of the specification. It also outlined how the Messaging specification alleviates the tedium of programming with deferred synchronous operations via the Dynamic Invocation Interface (DII) and avoids the weak reliability semantics of one-way operations. In this column, we focus on asynchronous method invocation (AMI), which is a core part of the new CORBA Messaging specification. A key feature of CORBA AMI is that operations can be invoked asynchronously using the static invocation interface (SII), thereby eliminating much of the complexity inherent in the DII deferred synchronous model. This column illustrates how to write CORBA applications using the two AMI programming models.
