无法从Jax-ws Web Service返回列表的ArrayList
[英]Cannot return ArrayList of Lists from Jax-ws Web Service
问题描述
I want to return ArrayList which contains List objects, through JAX-WS. 
我想通过JAX-WS返回包含List对象的ArrayList。
This is my method 这是我的方法
public ArrayList allTokens() {
ArrayList allItems = new ArrayList();
List myList1 = new ArrayList();
myList1.add("Indunil");
myList1.add(22);
List myList2 = new ArrayList();
myList2.add("Tharanga");
myList2.add(20);
//adding lists to all items
allItems.add(myList1);
allItems.add(myList2);
return(allItems);
}
Following error is showing when I call web service: 当我调用Web服务时显示以下错误：
javax.xml.ws.WebServiceException: javax.xml.bind.MarshalException - with linked exception: [com.sun.istack.SAXException2: class java.util.ArrayList nor any of its super class is known to this context.
I tried some JAXB, but didn't able to solve my problem. 我尝试了一些JAXB，但无法解决我的问题。 I don't know how to do JXAB properly. 我不知道如何正确地做JXAB。 This is for my final project of my degree. 这是我学位的最终项目。

I think using the List (which is parent of ArrayList) will work . 我认为使用List（它是ArrayList的父级）将起作用。 Please try with below code: 请尝试使用以下代码：
public static List<List> allTokens() {
List<List> allItems = new ArrayList<List>();
List<String> myList1 = new ArrayList<String>();
myList1.add("Indunil");
myList1.add("22");
List<String> myList2 = new ArrayList<String>();
myList1.add("Tharanga");
myList1.add("20");
//adding lists to all items
allItems.add(myList1);
allItems.add(myList2);
return(allItems);
}
