将notes字段转换为jsonjavaarray

在xpages应用程序中,我使用com.ibm.commons.util.io.json.jsonjavaobject类来获取联系人详细信息(电话列表)。

我要绑定到重复控件的对象,该控件将显示联系人的所有联系人详细信息。

我想将jsonjavaarray的值保存到notes字段,当我通过xpage显示文档时,我想再次读取它,所以我必须转换它。

以下是json在字段中的保存方式:

{
    "locations": [
        {
            "lat": "23.053",
            "long": "72.629",
            "location": "ABC",
            "address": "DEF",
            "city": "Ahmedabad",
            "state": "Gujrat",
            "phonenumber": "1234567"
        },
        {
            "lat": "23.053",
            "long": "72.629",
            "location": "ABC",
            "address": "DEF",
            "city": "Ahmedabad",
            "state": "Gujrat",
            "phonenumber": "1234567"
        },
        {
            "lat": "23.053",
            "long": "72.629",
            "location": "ABC",
            "address": "DEF",
            "city": "Ahmedabad",
            "state": "Gujrat",
            "phonenumber": "1234567"
        },
        {
            "lat": "23.053",
            "long": "72.629",
            "location": "ABC",
            "address": "DEF",
            "city": "Ahmedabad",
            "state": "Gujrat",
            "phonenumber": "1234567"
        },
        {
            "lat": "23.053",
            "long": "72.629",
            "location": "ABC",
            "address": "DEF",
            "city": "Ahmedabad",
            "state": "Gujrat",
            "phonenumber": "1234567"
        }
    ]
}

下面是我如何读取字段并将其转换为jsonobject并读取数组:

String codeString = doc.getItemValueString(fieldName);
JsonJavaObject objJson = new JsonJavaObject(codeString);                
JsonJavaArray arrJson = objJson.getAsArray("locations");

我得到的错误如下:

com.ibm.commons.util.io.json.jsonjavaobject中的错误,第56行: java.lang.ArrayIndexOutOfBoundsException:数组索引超出范围:1

有人能解释一下我做错了什么吗?
