This week’s tip is in two parts. First comes the question:
Scenario: You are creating your first Web service. You have been told to create a service that accepts a price (which for this example can be a float) and return a boolean. You are working in Java, but you know that you want to expose the Web service to a number of .NET clients. Interoperability of this service is key to the success of the project.
You start by creating your method:
public boolean MyWebMethod(float price)
//some code goes here
Although technically this may work, there are potentially two things wrong with this approach – especially if you are designing with interoperability in mind. What?
