Recently, I was working on an agent that used a web service to export data. Now, I don’t know if you noticed, but for some reason, consuming services is way easier in LotusScript than it is in Java. As far as I know, and I could be wrong, you need to import Axis in Java […]
With the abundance of posts out there, I thought I would chip in my 5 cents worth. Yes, I know I am a bit late. Release 8.5.1 is for LotusScript developer everything he could ever hope for. Specially if you are into OO programming. Finally you don’t have to check your old classes what parameters […]
In part 10 of Design pattern series we will take look at Builder design pattern. Albeit much similarity, this pattern it is not to be mistaken with Abstract factory pattern.

This week, I present to you not much used, but quite useful Mediator pattern. Mediator pattern provides a unified interface to set of interfaces in a subsystem. Or, to simplify… Mediator pattern is mediator for communication between several classes.

In this article, I would like to present you a design pattern that is not so common, but for sure, I wish, that in the past I would have used it. It would certainly make my life much easier. So, what is this Template method pattern all about? The Template Method Pattern defines the skeleton […]
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 […]
Another quite useful pattern is Adapter pattern. Adapters represent an interface between two different classes. For example imagine being a continental EU citizen travelling to UK. For you to plug in to UK power plug, you need an adapter that will take the interface your connector has and output the interface UK power plug demands.
One would think, creating and running web services on ND8 should not be incompatible with ND7 process. Wrong.

Web services created/built on ND8 […]
