Sonatype GWT REST is a "generic" (low-level) fully-compliant (real) REST async client for GWT that avoids "native" GWT RPC completely. It adds "generic" capability to drive any JSON, XML, or plain text-enabled REST Service from GWT client applications. Sonatype Nexus is powered by the restlet.org REST Framework, so this client is usable with all REST services which are backed by the restlet.org Java framework or implement real REST.

uWiki is a minimalistic wiki engine. All actions are implemented in external scripts. These scripts are wikified, and thus the wiki is extensible by itself. All dynamic access is protected through ACLs. Wiki content and Web content can be mixed in the same directory hierarchy. Markup engines and revision control are plugin-able. Currently, asciidoc as the markup engine and git as the revision control backend are provided. Subdirectories can form independent sub-wikis with own revision control. Features like distributed pages that syncronize between wikis, spam protection, and batch jobs to schedule mirroring of other content (bittorrent, git, rsync, and wget) are in planning.
