Jolokia is a fresh way of accessing JMX MBeans remotely. It is different from JSR-160 connectors, as it is an agent based approach that uses JSON over HTTP for its communication. It provides new features for JMX remoting: bulk requests allow for multiple JMX operations with a single remote server roundtrip, there is a fine-grained security mechanism for restricting JMX access on specific JMX operations, JSR-160 proxy mode, and history tracking, to name a few. Jolokia's origins are in jmx4perl. Client bindings in addition to Perl have already been added, and more are planned.
CI-Eye is a powerful continuous integration build radiator requiring no installation and almost no set-up. CI-Eye talks to many different CI servers through their REST APIs (so no plug-ins are required). Currently, support is offered for Hudson, Jenkins, and TeamCity. CI-Eye runs as a standalone Web application.
Orient Key/Value Server is based on the Document Database technology and is accessible as an embedded repository via Java APIs or via HTTP using a RESTful API. It uses a new algorithm called RB+Tree, derived from the Red-Black Tree to maintain tree balance, and from the B+Tree storing the links to records in pages to optimize memory consumption and loading time. Orient Key/Value Server scales out very well in a cluster with thousands of running machines: Orient will divide the load among all the nodes. Clustering, by default, works in auto-discovery mode: when a node starts, it attaches itself to the cluster if one is available. When a node goes down, the cluster automatically rebalances itself.
jmxtrans is effectively the missing connector between JMX and whatever logging or graphing package that you can dream up. jmxtrans is very powerful tool that reads JSON configuration files specifying servers/ports and JMX domains/attributes and then outputs the data in whatever format you want via special "Writer" objects that you can code up yourself. It does this with a very efficient engine design that will scale to querying literally thousands of machines. The core engine is pretty solid and writers are included for cacti/rrdtool, graphite, and stdout.
RestyGWT is a GWT generator for REST services and JSON encoded data transfer objects. RestyGWT Rest Services allow you to define an asynchronous service API which is then implemented via GWT deferred binding by RestyGWT. It features generation of asynchronous RESTful JSON based service proxies, encoding and decoding of Java objects to JSON, and an easy-to-use REST API.
