关于Axis2传回ArrayList的问题

[cscxxx]

我正在学习web service想传一个ArrayList给客户端但报错请教
service class如下:

public class ReturnArrayList {
	public ArrayList sayHelloArray(String user){
		ArrayList al = new ArrayList();
		al.add("str01");
		al.add("str02");
		al.add("str02");
		al.add("str02");
		return al;
	}
}

用eclipse发布成web service没问题
再使用eclipse -> Axis2 Code Generator产生client如下:
Axis2ArrayListTest.java
Axis2ArrayListTestCallbackHandler.java
Axis2ArrayListTestStub.java
ExtensionMapper.java
SayHelloArray.java
SayHelloArrayResponse.java
自己写的如下:

public class testAxis2ArrayListClient {
	public static void main(String[] args) {
		try {
			Axis2ArrayListTest a2t = new Axis2ArrayListTestStub();
			SayHelloArray sayHelloArray = new SayHelloArray();
			sayHelloArray.setUser("Garrick");
			SayHelloArrayResponse response = a2t.sayHelloArray(sayHelloArray);
			ArrayList al = (ArrayList) response.get_return();
			Iterator it = al.iterator();
			while(it.hasNext()){
				System.out.println(it.next());
			}
		} catch (AxisFault e) {
			e.printStackTrace();
		} catch (RemoteException e) {
			e.printStackTrace();
		}
		
	}
}

产生错误如下:

有人知道吗?传数组也可以。

我只知道错误信息大概是两边类型不对应问题，，具体没玩过WEBSERVICE= =
