Artemis jolokia rest api returns no real data (Jsr160ProxyNotEnabledByDefaultAnymoreDispatcher)

Question

• I've an Artemis Broker (2.17) running on my dev machine for local testing.
• From the web-console I've extractet the request to get the names of all queues.

When I execute the request from the browser console i get a JSON result like this:

{
    "request": {
        "mbean": "org.apache.activemq.artemis:broker=\"MyBroker\"",
        "arguments": [
            "ANYCAST"
        ],
        "type": "exec",
        "operation": "getQueueNames(java.lang.String)"
    },
    "value": [
        "DLQ",
        "ExpiryQueue"
    ],
    "timestamp": 1624274952,
    "status": 200
}

When I execute the same request from my code I get a very different result:

{
    "request": {
        "type": "version"
    },
    "value": {
        "agent": "1.6.2",
        "protocol": "7.2",
        "config": {
            "listenForHttpService": "true",
            "authIgnoreCerts": "false",
            "agentId": "192.168.1.41-30064-15b82644-servlet",
            "debug": "false",
            "agentType": "servlet",
            "policyLocation": "file:/C:/Artemis/MyBroker/etc//jolokia-access.xml",
            "agentContext": "/jolokia",
            "serializeException": "false",
            "mimeType": "text/plain",
            "dispatcherClasses": "org.jolokia.http.Jsr160ProxyNotEnabledByDefaultAnymoreDispatcher",
            "authMode": "basic",
            "authMatch": "any",
            "streaming": "true",
            "canonicalNaming": "true",
            "historyMaxEntries": "10",
            "allowErrorDetails": "false",
            "allowDnsReverseLookup": "true",
            "realm": "jolokia",
            "includeStackTrace": "false",
            "mbeanQualifier": "qualifier=hawtio",
            "useRestrictorService": "false",
            "debugMaxEntries": "100"
        },
        "info": {
            "product": "jetty",
            "vendor": "Eclipse",
            "version": "9.4.27.v20200227"
        }
    },
    "timestamp": 1624274809,
    "status": 200
}

Jsr160ProxyNotEnabledByDefaultAnymoreDispatcher seams very strange. But when searching for this name I couldn't realy find anything usefull. Also I cannot find any usefull information in the Artemis logs.

Here is my code:

using System;
using System.Net.Http;
using System.Text;
using System.Threading;

const String username = "admin";
const String password = "password";
var encoded = Convert.ToBase64String( Encoding.GetEncoding( "ISO-8859-1" )
                                              .GetBytes( username + ":" + password ) );
var url = "http://localhost:8161/console/jolokia/?maxDepth=7&maxCollectionSize=50000&ignoreErrors=true&canonicalNaming=false";
var http = new HttpClient();
http.BaseAddress = new("http://localhost:8161/");
http.DefaultRequestHeaders.Add( "Authorization", "Basic " + encoded );
http.DefaultRequestHeaders.Add( "Origin", "http://localhost:8161/" );
var request = new HttpRequestMessage
{
    Method = HttpMethod.Get,
    RequestUri = new(url),
    Content = new StringContent( "{\"type\":\"exec\",\"mbean\":\"org.apache.activemq.artemis:broker=\\\"MyBroker\\\"\",\"operation\":\"getQueueNames(java.lang.String)\",\"arguments\":[\"ANYCAST\"]}" )
};
request.Content.Headers.ContentType = new("text/json");
var response = await http.SendAsync( request, HttpCompletionOption.ResponseHeadersRead, CancellationToken.None );
if ( response.IsSuccessStatusCode )
{
    var content = await response.Content.ReadAsStringAsync();
    Console.WriteLine( content );
}
else
    Console.WriteLine( "Request failed...." );

Console.ReadLine();

• In the bootstrap.xml the binding is set to 0.0.0.0 which should be ok.
• jolokia-access.xml contained <allow-origin>*://localhost*</allow-origin> which should be fine but just to be sure I've replaced it with <allow-origin>*</allow-origin>

Is there something I need to configure to make this work?

Answer 1

Your code is using an HTTP GET, but it is using a fixed URL (i.e. http://localhost:8161/console/jolokia/?maxDepth=7&maxCollectionSize=50000&ignoreErrors=true&canonicalNaming=false and a payload (i.e. {"type":"exec","mbean":"org.apache.activemq.artemis:broker="MyBroker","operation":"getQueueNames(java.lang.String)","arguments":["ANYCAST"]}"). This does not conform with the Jolokia protocol.

If you use an HTTP GET then everything should be in the URL itself presumably just like it was your browser console. For example, use this:

http://localhost:8161/console/jolokia/exec/org.apache.activemq.artemis:broker="MyBroker"/getQueueNames/ANYCAST

Answer 2

Jolokia requests can be sent in two ways: Either as a HTTP GET request, in which case the request parameters are encoded completely in the URL. Or as a POST request where the request is put into a JSON payload in the HTTP request's body. See the Jolokia Protocol for further details.

When the Jolokia service doesn't get any request it will answer with service information, ie:

{
    "request": {
        "type": "version"
    },
    "value": {
...

To request the queue names using an HTTP GET request

curl -H "Origin:http://localhost:8161" -u admin:admin http://localhost:8161/console/jolokia/exec/org.apache.activemq.artemis:broker=\"MyBroker\"/getQueueNames/ANYCAST

To request the queue names using an HTTP POST request

curl -X POST -H "Content-Type: application/json" -H "Origin:http://localhost:8161" -u admin:admin http://localhost:8161/console/jolokia -d '{"type" : "EXEC", "mbean" : "org.apache.activemq.artemis:broker=\"MyBroker\"", "operation" : "getQueueNames", "arguments" : ["ANYCAST"]}'
