I was looking for the Geronimo roadmap when i stumbled over their news page. (Didn’t find the roadmap btw) They have sent out a response to the copyright infringement claims from JBOSS group. It seems they’ve done a thorough investigation, and actually found some problems with the JBOSS code. It will be interesting to see the response.
Article on extending Struts here. As he points out extending Struts could resource intensive for maintaining and developing your extensions. Many of the cases like triggering events at app startup/shutdown and for every request can be handled easily with Servlet Listeners and Filters, and it might not even be dependent on Struts. I’d rather investigate the possibility of using them, instead of extending Struts.
Seems like there is a quite extensive list of ORMs on .NET too. Check it out here.
