Have you ever wondered how you could call already written and quite useful Java classes in your LotusScript code? To me, this moment was, when I was trying to implement other department’s code into my own. Unfortunately I wasn’t skilled enough in ways of object development, LS2J and googling back then to actually figure out […]
One of the most used patterns is also a pattern that hears by the name Observer. What does it do? Well, imagine you have a stock portfolio and you need to notify your investors every time the value of their stock changes. First, your investors need to subscribe to the stock they would like to […]
In my years of developing software, I come to realize that what every software development department needs is: some sort of IDE with a compiler version control and bug tracking. Usually you get stuck with IDE with a compiler. Everything else is up to you. But how are things in Lotus Notes?
One would think, creating and running web services on ND8 should not be incompatible with ND7 process. Wrong. There are a few quite important differences when creating web services on ND8 instead of ND7. You can now create clients. The one we’ve all been waiting for since ND7 came out. Web services created/built on ND8 […]
I have found an interesting challenge last week. For some reason, I had to have a document on web that would show a computed table of products and there would be some content before and after. The trick however is, that we use some sort of CRM database for our web content and documents use […]
Last week I wrote my first web service (yay!). I am not going to write about that, as process of creating web services is nicely described at IBM developerworks. But, back to my service. The service is used to do some work that only my consumer application should be able to do. However, due to […]
Day 0, Check-in The flight was OK, check-in without issues and registration to the conference was prompt, which scared the hell out of me. You know what they say. If everything goes right, something is bound to go terribly wrong. Conference registration people were kind enough to give me shoulder bag with loads and loads […]
As every year, I am attending The View’s Lotus Developer 2008 Europe conference, which will be held in Amsterdam from November 11th till November 13th. This is the biggest Lotus Notes conference taking place in Europe and since it is just a couple of months prior to LotuSphere conference, I can again hope for some […]
For those, skilled in Java development, Decorator patterns are nothing new, as they are quite common in Java, i.e. FileInputStream with it’s decorator BufferedInputStream class. The definition says: The Decorator Pattern attaches additional responsibilities to an object dynamically. More theoretical background can be found on Wikipedia.
One of the simplest and most commonly used patterns is definitely strategy pattern. We cannot pass a boring definition, so here you go: The Strategy Pattern defines a family of algorithms, encapsulates each one, and makes them interchangeable. Strategy algorithm vary independently from clients that use it. You will find out that all strategy pattern […]
