What’s Next?
In the next chapter, we take a look at a technology that allows XML to be used as a data format in an important request and response model: XML-RPC. XML Remote Procedure Calls allow clients in a distributed system to request that tasks be executed on a server (or servers) on another portion of the network. Until recently, RPC has declined in popularity, mostly due to the surge of RMI-based technologies in the Java space (most notably, EJB). However, with XML as a data format, XML-RPC is a new solution for many problems that could not be solved cleanly or efficiently without RPC. We take a look at XML-RPC next, and in particular, at the Java libraries available.
