I have getter/setter defined for properties, but still cannot send object of this class through WS, because the JBOSS generated WSDL doesn't include correct information for ArrayList. How can I correct this?

package org.jboss.tutorial.webservice.bean;

import java.util.*;
import java.io.*;

public class Something {
 private int a;
 private double b;


 private HashMap<String, ArrayList<String>> c;

 public Something() {
 a = 1;
 b = 2.0;
 c = new HashMap<String, ArrayList<String>>();
 {
 ArrayList<String> arr = new ArrayList<String>();
 arr.add("This is fun");
 arr.add("Interesting");
 arr.add("What is this?");
 c.put("thought", arr);
 }
 {
 ArrayList<String> arr = new ArrayList<String>();
 arr.add("Kaveh");
 arr.add("David");
 arr.add("Costa");
 c.put("name", arr);
 }
 {
 ArrayList<String> arr = new ArrayList<String>();
 arr.add("green apple");
 arr.add("orange orange");
 arr.add("yellow mango");
 c.put("fruit", arr);
 }
 {
 ArrayList<String> arr = new ArrayList<String>();
 arr.add("they shoot horse");
 arr.add("sleppless in seattle");
 arr.add("thank you for smoking");
 c.put("movie", arr);
 }
 }

 public int getA() {
 return a;
 }

 public void setA(int a) {
 this.a = a;
 }

 public double getB() {
 return b;
 }

 public void setB(double b) {
 this.b = b;
 }

 public HashMap<String, ArrayList<String>> getC() {
 return c;
 }

 public void setC(HashMap<String, ArrayList<String>> c) {
 this.c = c;
 }

 public ArrayList<String> getC(String i) {
 return c.get(i);
 }

 public void setC(String i, ArrayList<String> c) {
 this.c.put(i, c);
 }

}
