    Default Project layout for web service

    Hello,
    I am new to Java and I am trying to create my first web service. I am using Eclipse, Java and Axis2 to do so. I have the service up an running but now I want to ensure that my business logic and so on "lives" in the right place.

    I have created a new project, added a new package and to that a new class called MyService.java

    package pkg;
    public class MyService{
     
    	public MyService() {}
     
    	public String SayHello(String name){
    		return "Hello " + name;
    	}
     
    	public int CalcStuff(int first, int second){
    		return first + second;
    	}
    }

    And thats it. It works and I can call the web service from another application.
    Now I want to learn the proper way to do the above, assuming that it is incorrect. I think that I should change the MyService Class to not contain the "business logic" but instead have something like this:
    public class MyService {
     
    	public MyService() {}
     
    	public String SayHello(String name){
     
    		return Hello.getHello(name); //calls a class that has business logic
    	}
     
    	public int AddNumbers(int first, int second){
    		return Numbers.AddNumbers(first, second); //calls a class that has business logic
    	}
    }

    Is the second way better? Is there a third way that is way better? Or is the first way I did it ok?

    I know these are small methods, but I want to understand the way it should be before I start making actual web services.

    Thanks

    Default Re: Project layout for web service

    The second way is much better than the first way as it leaves the service class unchanged when we need to change the business logic. It s always better to keep the interface class(accessed directly by client) unchanged.
