'''XML-RPC Delight is meant for''': All users that want to have their java components connected using a web-based protocol but don't want to waste time with defining the interfaces a second time in another language-independend description format and then generate stubs and skeletons and so on.[[BR]]
'''XML-RPC Delight is an addon''' to the XML-RPC specification ([http://www.xmlrpc.com/spec]) and builds on apache's implementation ([http://ws.apache.org/xmlrpc/]), version 1.1 (Download [https://delight.opendfki.de/repos/trunk/XmlRpcDelight/import/xmlrpc-1.1_all.jar here]).
----
== Design Objectives ==
- have java components interact over internet wire with a minimum of programming and
configuration effort
- preserve XML-RPC compliance
- make '''EVERY''' type XML-RPC transportable with '''minimal coding effort''' (ideally, not a single line of extra code!)
- do not interfere with design of remote interfaces. Within the remote calls, one should be able to use any
type or interface he wants.
- neither the client nor the server has to be forced to load configuration files
or register factories programmatically in order to use non XML-RPC compliant types in remote calls.
== Overview ==
XML-RPC Delight creates remote clients to java APIs that are supposed to be used remotely. XML-RPC Delight does this at runtime, not at compile time! [[BR]]
In case the API uses types which are not XML-RPC compliant, '''java annotations''' and user-defined conversion methods allow for '''automatic transformation of types''' to and from a XML-RPC compliant representation. Optimally, one can use non-compliant java classes in XML-RPC calls without having to code a single line of code!!
While all the automatic conversion is done, communication with the server is still XML-RPC compliant so that remote methods can still be called by non-java languages.

Latest Version (2.1):
[http://delight.opendfki.de/repos/trunk/XmlRpcDelight/dist/XmlRpcDelight-2.1_29.11.2007.zip]
'''Changes'''
- support for sets added
- new automatic null-value masking feature: {{{XmlRpc.useAutomaticNullMasking( true )}}} enables the feature [[BR]]
values for all standard XML-RPC types (except BASE64), arrays and ''Convertable'' parameters can now be null-values. !XmlRpcBeans can have null-valued properties. !ParameterConverters can handle null-values separately, but also can rely on the new masking feature.
- Note: this version is java 1.5 compliant
Older Versions:
v 2.0: [http://delight.opendfki.de/repos/trunk/XmlRpcDelight/dist/XmlRpcDelight-2.0_22.05.2007.zip]
'''Changes'''
- Contains annotation not needed anymore
- Array support added (also supported: primitive type arrays)
- Nested parameters and return types for collections, maps and arrays possible
- 'null'-parameters can be used together with !ParameterConverters
- Better logging support
