When Jetty 7.5.0 is released we will have officially started to dabble in the area of distributed session handling and storage. To start this out we have created a set of abstract classes around the general concept of NoSQL support, and have prepared an initial implementation using MongoDB. We will Read more…
The websocket protocol specification is approaching final and the Jetty implementation and API have been tracking the draft and is ready when the spec and browsers are available. More over, Jetty release 7.5.0 now includes a capable websocket java client that can be used for non browser applications or Read more…
I have done some very rough preliminary benchmarks on the latest cometd-2.4.0-SNAPSHOT with the latest Jetty-7.5.0-SNAPSHOT and the results are rather impressive. The features that these two releases have added are: Optimised Jetty NIO with latest JVMs and JITs considered. Latest websocket draft implemented and optimised. Websocket client implemented. Jackson Read more…
It all started when my colleague Joakim showed me the results of some JSON libraries benchmarks he was doing, which showed Jackson to be the clear winner among many libraries. So I decided that for the upcoming CometD 2.4.0 release it would have been good to make CometD independent of Read more…
Jetty JMX Webservice is a webapp providing a RESTful API to query JMX mbeans and invoke mbean operations without the hassle that comes with RMI. No more arguments with your firewall admin, just a single http port. That alone might not be a killer feature, but Jetty JMX Webservice also Read more…
The Jetty Overlay Deployer allows multiple WAR files to be overlayed so that a web application can be customised, configured and deployed without the need to unpack, modify and repack the WAR file. This has the benefits of: The WAR file may be kept immutable, even signed, so that it Read more…
In the last blog entry I talked about message flow control using CometD‘s lazy channels. Now I want to show how it is possible to achieve a similar flow control using specialized listeners that allow to manipulate the ServerSession message queue. The ServerSession message queue is a data structure that Read more…
Since the very beginning, Jetty has been IOC friendly and thus has been able to be configured with spring. But the injecting and assembling the jetty container is not the only need that Jetty has for configuration and there are several other configuration files (eg contexts/yourapp.xml, jetty-web.xml, jetty-env.xml) that have Read more…
The WebSockets protocol and API is an emerging standard to provide better bidirectional communication between a browser (or other web client) and a server. It is intended to eventually replace the comet techniques like long polling. Jetty has supported the various websocket drafts in the 7.x and 8.x releases and Read more…
