StringReturn.jws
by Jeffrey K. Brown

I was curious at this point to see what would happen if I started importing additional
libraries and then writing my own methods not in the book.  This worked well.

I was able to connect to this web service with a quick and dirty C#.NET application.
Basically, I would write a word or two in a text box, and when you clicked a button,
the web service would be invoked with the parameter from the text box.

This code doesn't do anything interesting or even exciting.  Basically, I needed a
web service that does something so that I could test it and play with it.

import java.util.*;

public class StringReturn {

	// This is basically an echo function.
	public String returnString (String whole) {
		return whole;
	}

	// If we pass a sentence, we tokenize and return the first word.
	public String returnFirst (String whole) {

		try {
			StringTokenizer st = new StringTokenizer(whole);
			return st.nextToken();
		}
		catch (Exception e) {
			return "Exception";
		}
	}
	
	// This returns an array of Strings
	public String[] returnArray (String whole) {
		int i=0;
		String[] array = new String[10];
		
		for (i=0; i<10; ++i) {
			array[i] = whole + " " + i;
		}

		return array;
	}
