The Apache XML-RPC team has announced the availability of Apache XML-RPC, version 3. Version 3 is an almost complete rewrite of its predecessor. Although complying to the XML-RPC specification by default, it introduces the concept of so-called vendor extensions. Vendor extensions are available only, if both client and server are using Apache XML-RPC 3. Available vendor extensions include:
A streaming mode allows running client and server with a low memory profile, regardless of any document size.
XML-RPC request and response may be compressed using gzip
Custom data types are supported, in particular null, byte, short, long, float, big decimal, big integer, DOM nodes, Serializable objects, Calendar
Additionally, support for dynamic client generation is available. In other words, if the servers methods are implementing an interface, then the client may create an instance of the same interface, which is actually invoking the servers methods.
