I'm trying to set up an application server to run a simple website and a Java client application that needs to communicate back to a Java server. What I'd like to do is the following: Website/web application server at http://www.mydomain.com Applet and/or Java Web Start jar at http://files.mydomain.com Server listening on some port at...
I have my thoughts about this matter but it seems that a lot of libraries and products let third party libs bleed into the API. Logging is a perfect example of this. Nearly everything exposes the need for you to configure that logging API rather than using a provider interface that you can implement and give to the lib. Is aiming to wra...
Hi, what I mean by that is: I basically have a class that has too many properties and functions now. To remain performant and understandable, it needs to shrink somehow. But I still need all those properties and methods somewhere. It's like this right now: class Apple float seedCount; ... ...about 25 variables and properties here...

Hello: I created a simple RPC server to perform certain tasks common to our teams, but which are called from different networks. The server looks like this (I don't include error handling for brevity): from twisted.internet.protocol import Protocol, Factory from twisted.internet import reactor import json class MyProtocol(Protocol): ...
I'm just getting into how to write a good architecture of a good software system, and I'm learning how to separate high level components into Layers. In this case, I'm trying to use Tiers, so as to model each Layer as a black box. There are 4 tiers in my architecture: Presentation, Application Services, Business Logic, and Domain/Persis...
There are many, many examples in books, and on the internet about how to use Servlets as JSPs. But I would like to know what the best way to go about using them, with a mind to good architecture. Should there be a one-to-one relation of Servlets to JSPs? Acting like ASP.NET "Code-Behind" pages? Or more like ASP.NET MVC, with a single S...
I have several applications that need to read and write application settings. Since one of the apps is a legacy c++ app with hundreds of settings in the registry (and that isn't bound to change) and there are also some settings stored in a proprietary database format I'm wondering how the architecture could be setup to allow a single in...
I have previously really only worked on your general 3-tier system. I am now tasked with something slightly different. I now need to retrieve files from 3rd party location using FTP. In the few times in the past I would have built a console app run and ran it on a schedule. It would have worked but maybe not been the best. I am looking...

Hi folks, I am in the process of building/architecting a business social network web application that has a component that I think will lead to major scalability issues and I'd like to get some feedback/thoughts on the best way forward. The application has a User object. The idea is, that every time a new user joins the system he ranks...
Does anybody knows good, short and slim tutorials, which describe actual/modern web-application architectures / patterns (especially for ASP.NET based (classic and MVC) applications (maybe also with embedded Silverlight components) ? How would you you design today an ASP.NET application which uses different datasources (databases, servic...
I've been wondering for a while; how does websites like facebook code to be able to have multiple servers? How can the code take in account that several servers will be running the same code and gain from adding more? Or does the webserver perhaps deal with this regardless of the code? ...

In other words I want to structure a large web-application where I have a solution with more web-application projects. These projects are more or less independent "modules". One project should be a kind of frame applicatio...
I need to create an architecture diagram for an existing system. I want to show the "big picture" as well as small details. What makes more sense: Create one diagram for the big picture, and a separate diagram for each smaller component. Create one diagram with all details. I guess this requires correct tooling to be able to show a si...
I'm looking for a simple way to determine whether a system is 32- or 64-bit from within Perl 5. I have read the perlvar manual page backwards and forwards, and have not discovered a variable that contains the system's CPU architecture (the CPU architecture Perl was compiled for will come close enough). This is the closest I have come: c...
