Ed Burns's blog Project Idea: memcached JSF Component Posted by edburns on November 23, 2009 at 12:14 PM PST While speaking at the Globalcode Developer's conference in Rio de Janeiro, I met a dynamic and intelligent student by the name of Thiago Diogo. Thiaogo presented his group's work on student project to provide a real, mission critical distributed application for his university, Universidade Federal Fulminense. They chose JSF 1.2 and Seam as a part of their stack. One idea Thiaogo shared with me was a memcached JSF component. We kicked the idea around and I mentioned it would be pretty easy to invent a JSF component that acted like a `<span>` tag that simply meant, “the rendered output of any JSF components inside of me should come from memcached, if possible”. I don't have time to start on this idea right now, so I thought I'd share it out here in my blog in case anyone else wanted to pick it up, or if anyone else has already done this! When I get time, I'll try adding it to the Mojarra sandbox components, but in the meantime, anyone can have at it!

Submitted by thiagodiogo on Tue, 2009-11-24 15:51. Hi Ed, thanks for the mention in your blog about the idea. My team want to help you with the development of this component. Here in our project we've created a @CacheResult annotation to be placed at the service's methods (we use the App Service pattern) to store in one memcached instance the return of that method for next calls. We can think in something like this to the creation of our component. How can I and my team get involved with this component development? Again, thanks for remember the idea. And we're waiting you here in Olympic Games 2016! See you. Login or register to post comments Use a neutral API Submitted by pmuir on Mon, 2009-11-23 14:14. Ed, one of the components we have always had in Seam was the tag, which rendered any nested tags using cached output (we never ventured into allowing input components inside these regions, not sure if that is something you are envisaging?). Anyway, a mistake we made early on was to essentially tie the component to the JBoss Cache API (which we later retrofitted to a generic API). As a result I would recommend not tying yourself to any particular API, but instead use a neutral one. In general, Map is a great fit for a cache access (and maybe ConcurrentMap for adding stuff to the cache), so I would suggest using that. You could then provide a default implementation based on memcached (which is definitely a pseudo-standard API :-) Login or register to post comments		Categories Java Enterprise Community J2EE Patterns Business Extreme Programming Programming JSR JavaOne Security Netbeans Java Desktop Glassfish Blogs Web Applications General Java Patterns Databases Performance Archives November 2009 October 2009 September 2009 July 2009 June 2009 May 2009 April 2009 March 2009 February 2009 January 2009 December 2008 November 2008 October 2008 September 2008 August 2008 June 2008 April 2008 November 2007 August 2007 July 2007 May 2007 March 2007 January 2007 December 2006 November 2006 October 2006 September 2006 August 2006 July 2006 June 2006 May 2006 April 2006 March 2006 February 2006 January 2006 December 2005 October 2005 September 2005 August 2005 July 2005 June 2005 May 2005 April 2005 March 2005 August 2004 June 2004 Recent Entries Project Idea: memcached JSF Component JSF2 Facelet Tag Handlers JSF2 and POST Redirect GET
