How to Catch Message Through IronMQ in java


I am trying to fetch some message from IronMQ as well as put some message there through Java program. I have written the following code but I get a exception, please help.

Thanks in Advance:

 package com.iron;

import java.io.IOException;
import java.util.Map;

import io.iron.ironmq.Client;
import io.iron.ironmq.Message;
import io.iron.ironmq.Queue;
import io.iron.ironmq.Cloud;

public class Test {

    public static void main(String[] args) 
    {
        String ProjectId;
        String ProjectToken;
        ProjectId="actual ID in String";
        ProjectToken="Project token in string";
        Map<String,String> env=System.getenv();
        Client client = new Client(env.get(ProjectId), env.get(ProjectToken), Cloud.ironAWSUSEast); 
        Queue queue = client.queue("my_queue");
        try 
        {
            queue.push("hello world!");
            Message msg = queue.get();
            System.out.println(msg.getBody());
        } 
        catch (IOException e) 
        {
            e.printStackTrace();
        }





    }


} 

The exception I get is

Exception in thread "main" java.lang.NoClassDefFoundError: com/google/gson/JsonSyntaxException
    at com.iron.Test.main(Test.java:20)`
Caused by: java.lang.ClassNotFoundException: com.google.gson.JsonSyntaxException

Solution

  • import io.iron.ironmq.Client;
    
    import io.iron.ironmq.Cloud;
    import io.iron.ironmq.Message;
    import io.iron.ironmq.Queue;
    
    public class IronMqTest5 {
    
        public static void main(String[] args) 
        {
            String projectId="54567889000c707";
            String token="3b3u7uwjwjj8726QZ9CO";
            String scheme="https";
            String host="mq-aws-us-east-1-2.iron.io";
            int port=443;
            try
            {
                Client c = new Client(projectId, token, new Cloud(scheme, host,port));
                //Client c = new Client(projectId, token, new Cloud("http", "localhost", 8080), apiVersion); //this is speified on the github doc but not working here
                Queue q = c.queue("ESIResponse");
                Message msg=q.get();
                System.out.println(msg.getBody());
    
            }
            catch(Exception e)
            {
                e.printStackTrace();
            }
        }
    
    
    }
