Hi everybody. following the post I did some time ago, I've reworked the XWiki XML RPC implementation. The previous XML RPC code was rather messy and contained a lot of duplicated code (basically the server side was re- implementing the same domain model already available in the Swizzle client-side jar). At first I managed to cut it down by basically removing all the duplicated code and linking directly to the Swizzle jar. Then I started working on object manipulation and I basically ended up with a complete rewrite. The new implementation is then based on two components: 1) The domain model classes and the XML RPC client 2) The server side implementation of the API (that is an extension of the Confluence one and uses the same domain model defined in 1) Overall we have the following "features": 1) The new implementation, on the server side, makes use of the XWiki Api wrapper (com.xpn.api.XWiki) instead of directly using the low level objects. Though I am not an expert of the XWiki internals, I think this is good for handling rights management (which is transparently done by the wrapper) 2) The implementation looks more robust and simple. 3) On the client side we still have interoperability with confluence and with the previous versions of XWiki. There are, however, two potential "bugs": 1) The client side jar requires Java 5.0. Infact it uses reflection and annotations to handle the "magic" of XML RPC communication (see MapObject.java). 2) We are basically giving up on Swizzle. The first "bug" can be easily solved, but this would lead to a less elegant and more bloated solution. The second "bug" is maybe political. Anyway if we want to go the Swizzle way, I also have a cut-down implementation that still uses swizzle (though I will need to patch the official swizzle-distribution for adding XWiki specific features, and in this is actually like having our own client) The current implementation is not feature complete (though XEclipse would already work fine with it and object edition could also be implemented) In the attachments you will find the current version of the implementation so you can review it and discuss future directions or issues: org.xwiki.xmlrpc.tar.gz is the "client side" jar that will be used by clients like XEclipse. com.xpn.xwiki.xmlrpc3.tar.gz is the package that would, in case, become part of XWiki. WDYT? Cheers, Fabio
