This Jetty Case Study takes a look at an intriguing software infrastructure product called 1060 NetKernelTM. Announcing the recent release of version 2 of the product, 1060 Research describes NetKernel as “an advanced service oriented microkernel”. Complex applications are produced by creating simple services and then aggregating or pipelining them Read more…
Because I consider some of the “features” of the latest 2.4 specification rather dubious or expensive, I was reluctant to implement them as core features of Jetty. Instead, Jetty 5.1 will use optional filters to provide JSR77 statistics, wrap under dispatch semantics, request events and request attribute events. Thus Jetty Read more…
Jetty 5.0.0 is out the door and the 2.4 servlet spec is implemented. So what’s next for Jetty and what’s next for the servlet API? It’s been a long journey for Jetty from it’s birth in late 1995 to the 5.0.0 release. When the core of Jetty was written, there Read more…
Christopher Merrill of Web Performance Inc has release a report of Servlet Performance, which included Jetty. Firstly it is good to see somebody again tackling the difficult task of benchmarking servlet containers. It is a difficult task and will always draw criticism and the results will always be disputed. The Read more…
This casestudy describes how Jetty has been used on our own sites, to show that we are “eating our own dogfood”. While there is nothing revolutionary in this blog, it is sometimes good to see examples of the ordinary and I believe it is a good example of how the Read more…
I have finally seen the JSP light! I think I actually like them and I will have to stop pouring scorn upon them (and all who use them)! So maybe 2004 is a bit late to be blogging about the wonders of JSPs, but the agent of my conversion has Read more…
The problem with the current breed of HTTP servlet session distribution mechanisms is that they do not scale well. I have just tried the first release of WADI ‘Web Application Distribution Infrastructure’, and it shows great promise as a next-generation session distribution mechanism that can be used for simple load Read more…
When I was systems administrator for the University of North Carolina at Charlotte department of Computer Science, I saw the need to establish an environment for our students to experiment with servlets. The goal was to provide a centralized system for our students to deploy their servlets / web-applications on Read more…
Web Application Filters were added to the 2.3 Servlet specification and have been enhanced in the just finalised 2.4 spec. Filters allow cross cutting concerns to be applied to a web application, which is exactly the gig of Aspect Oriented Programming (AOP). Being born and breed with OOP, I have Read more…
Taylor Crown has written a short paper regarding Combining the Servlet API and NIO, which has been briefly discussed on the serverside. NIO Servlets have often been discussed as the holy grail of java web application performance. The promise of efficient buffers and reduced thread loads are very attractive for Read more…
