  Can I write a module/filter that gets put into the processing pipleline in Tomcat BEFORE the web application even gets run? Something that I could turn on/off for each web application that tomcat is handling. is this possible? So basically it would be a re-usable filter that hooks into the web pipeline that could alter the requests behavior or perform/modify the requests. One example would be to log all ip's, or redirect based on the url, block the request, etc.

• Strategies on synching data and caching data between iphone and server

  - by Blankman

  Say I have a TODO list iphone app, that can be edited/viewed from both a web application and the iphone application. When on the iphone, when a user views all his todo lists, or sub-items, I would think that each time the user views a particular list it shouldn't be hitting the web applications API every-time, but rather cache locally the values and only hit the web when things change. What strategies are there for this type of scenerio?

• Is the development stack of java/spring/hibernate/eclipse/tomcat/mysql riddled with config hacking?

  - by Blankman

  From a M$ development perspective, using things like vs.net/c#/asp.net/asp.net mvc/sql server, things are pretty much smooth. (Obviously for someone coming from a microsoft background like me). Now I love the idea of open source, linux and terminal servering into the computer and doing things via the command line, no license issues really, etc. I've tried firing up eclipse etc., but I always seem to get stuck on some configuration issue or another. Does it get easier or is it just the territory when you are dealing with the java stack?
