The same behaviour is for any other "get some objects" (which works) and for "create some objects" (which does not).
I am using maven with its dependency for version 1.23, however I tried 1.12.0 and same exception was thrown.
We are using latest redmine 2.5.1.stable, however based on stacktrace, the communication between redmine web and this redmine api does not happen as the exception is thrown in "parseRespone" part of application.EDIT: I actually found the answer. I can't close the question as I am new. I was able to use Array.getString(i) to return the string value needed. Thanks for all the help.
I have JSON like this:
"example1",
"example2",
"example3",
"example4"
And I am trying to get the string value of those objects without using a key. How can I do that? The getString() for jsonObject require a key and I don't have one.
解决方案 I assume that you have a file :/home/user/file_001.json
the file contains this : `
{"age":34,"name":"myName","messages":["msg 1","msg 2","msg 3"]}
Now let's write a program that reads the file : /home/user/file_001.json
and converts its content to a java JSONObject.
package org.xml.
import java.io.FileNotFoundE
import java.io.FileR
import java.io.IOE
import java.util.I
import org.json.simple.JSONA
import org.json.simple.JSONO
import org.json.simple.parser.JSONP
import org.json.simple.parser.ParseE
public class JsonSimpleRead
@SuppressWarnings("unchecked")
public static void main(String[] args)
JSONParser parser = new JSONParser();
Object obj = parser.parse(new FileReader("/home/user/file_001.json"));
JSONObject jsonObject = (JSONObject)
String name = (String) jsonObject.get("name");
System.out.println(name);
long age = (Long) jsonObject.get("age");
System.out.println(age);
JSONArray msg = (JSONArray) jsonObject.get("messages");
Iterator&String& iterator = msg.iterator();
while (iterator.hasNext())
System.out.println(iterator.next());
catch (FileNotFoundException e)
e.printStackTrace();
catch (IOException e)
e.printStackTrace();
catch (ParseException e)
e.printStackTrace();

编辑：其实，我找到了答案。因为我是新的我无法关闭的问题。我能够使用Array.getString（i）返回所需的字符串值。感谢所有帮助。我有JSON是这样的：
“清单”：
“示例3”，
]} 和我试图获得这些对象的字符串值，而无需使用钥匙。我该怎么办呢？在的getString（）为JSONObject的要求的关键，我没有之一。解决方案 我假设你有一个文件： /home/user/file_001.json
该文件包含此：`
{“时代”：34，“名”：“MYNAME”，“消息”：“MSG 1”，“味精2”，“味精3”]} 现在让我们写一个程序，读取该文件： /home/user/file_001.json 其内容转换为一个java 的JSONObject 。 包org.xml.进口java.io.FileNotFoundE进口java.io.FileR进口java.io.IOException异常;进口java.util.Iterator的;进口org.json.simple.JSONA进口org.json.simple.JSONO进口org.json.simple.parser.JSONP进口org.json.simple.parser.ParseE

Unfortunatelly, it looks like this issue remains unsolve (or unsolvable), based on discussion with library owner :
However GET requests work. And for UPDATE/CREATE, you can use pure API like following. WARNING : Disabling SSL is dangerous, use only for testing purposes (like "does it even work?")
