Supporting Live Development of SOAP and CORBA Clients

We present middleware for a Client Development Environment that facilitates live development of client applications for SOAP or CORBA servers. We use JPie, a tightly integrated programming environment for live software construction in Java, as the target platform for our design. JPie provides dynamic classes whose signature and implementation can be modified at run time, with changes taking effect immediately upon existing instances of the class. We extend this model to automate addition, mutation, and deletion of dynamic server methods within dynamic clients. Our implementation simplifies distributed application development by masking technical differences between local and remote method invocations. Moreover, the live development model allows server-side changes to be dynamically integrated into a running client to support simultaneous live development of both the client and server.
