Hi, we are developing a complex core banking system containing 30+ systems. Because of orchestration and system collaboration, we typically use a BPMS (e.g. Jboss jBPM). Since systems are more independent and volume of human tasks is high (vs. software system operations) and also to gain benefit of async architecture I am looking for oth...

Hello, My application is following the MVC design pattern. The problem I keep running into is needing to call methods inside a Controller class from outside that Controller class (ex. A View class wants to call a Controller method, or a Manager class wants to call a Controller method). Is calling Controller methods in this way allowed ...
svn diff -rXX:HEAD Will give me a format like this, if there has been a merge between those revisions: Merged /<branch>:rXXX,XXX-XXX or Merged /<branch>:rXXX I'm not very familiar with regex and am trying to put together a pattern which will match all the numbers (merged revision numbers) AFTER matching the "Merged /branch:r" part. ...

A named pattern which I can use in subsequent rules: Out[1]= x_ But instead, I got: Out[1]= Pattern[Symbol @@ x,_] The documentation says tha...
Hi, I am making my own PHP-MVC framework. i have a question regarding Controller and View Association. I love the way Zend framework uses view within Controller as follow: $this->view->data = 'Data here'; so it can be used in view as follow: echo $this->data; I am wondering how can i implement this association. I want to remove c...
How can I indicate that a method will return a collection of objects in UML? Is there a better way to explain the relationship than to have a collection class as a return type? ...
Hi, I am trying to get myself accustomed with TDD, DI and Pattern-based Development. I am by far not new to Application Development, but since I plan to start a (big) new Project in a few months I want to be prepared and do it right from the start ;). The current architecture is based on a WCF-based AppServer, a MS SQL Database and WPF/...
Hi, I have read this manual: http://www.kernel.org/pub/software/scm/git/docs/gitignore.html As I am working with gitosis, I rather use a .gitignore than explicit git commands. Thus says the manual: Of course, not tracking files with git is just a matter of not calling git add on them. But it quickly becomes annoying to hav...
What would you suggest as a good and practical but simple pattern for a soloution with: HTML + JSP (as a view/presentation) SERVLETS (controller, request, session-handling) EJB (persistence, businesslogic) MySQL DB And is it necessary to use an own layer of DAO for persistence? I use JPA to persist objects to my DB. Should I with...
Very typically I have a situation where a given object will need to have many listeners. For instance, I might have class Elephant { public void addListener( ElephantListener listener ) { ... } } but I'll have many such situations. That is, I'll also have a Tiger object that'll have TigerListeners. Now, TigerListeners and Elephan...
Hi, The Circuit Breaker pattern, from the book Release It!, protects a service from requests while it is failing (or recovering). The net.msmq binding used with transactions give us nice retry and poison message capabilities. But I am missing the implementation of such a "Circuit breaker" pattern. A service is put under even heavier loa...

I'm currently building an android application with quite a few different connected activities. In each activity I've got a private updateView() method to update all the textViews and stuff on that screen. This gets called in the onResume() method so that each time the activity comes to the front it's views will be updated. Is this the r...
