B4J Library jMQTTBrokerExtended

This library is an extended version of jMQTTBroker2. It includes additional features (events, authentication, permissions, log backup, internal publishing) and fixes stability issues.

You can implement different levels of authentication:
- None: all accesses are anonymous.
- Generic: all clients must authenticate with a generic username and password.
- Per client: all clients must authenticate with their own username and password.
- Mixed: the access can be done with username and password, but also anonymously (guest mode).

You can set topic permissions for each user:
- Read: the client can subscribe to the topic.
- Write: the client can publish to the topic.

You can also define your own rules to allow or prohibit what a client can do.

There are 9 events:
- Authenticator(ClientID As String, Username As String, Password() As Byte) As Boolean
- Authorizator(ClientID As String, Username As String, Topic As String, Permission As String) As Boolean
- Connect(ClientID As String, Username As String, ProtocolName As String, ProtocolVersion As Byte, QOS As String, KeepAlive As Int, IsCleanSession As Boolean, IsDupFlag As Boolean, IsRetainFlag As Boolean, IsWillFlag As Boolean)
- Disconnect(ClientID As String, Username As String)
- ConnectionLost(ClientID As String, Username As String)
- LastWill(ClientID As String, Username As String, QOS As Byte, TopicName As String, Message() As Byte, IsRetainFlag As Boolean)
- Publish(ClientID As String, Username As String, QOS As String, TopicName As String, Message() As Byte, IsDupFlag As Boolean, IsRetainFlag As Boolean)
- Subscribe(ClientID As String, Username As String, RequestedQOS As String, TopicFilter As String)
- Unsubscribe(ClientID As String, Username As String, TopicFilter As String)

There are 5 severity levels for the log:
- Trace
- Debug
- Info (default)
- Warn
- Error

Five demonstration projects (B4J, B4A) are provided:
- "Authorization" demonstrates how to authorize or prohibit access or actions.
- "Chat" is a simple application for exchanging short messages between several users.
- "Multiplayers" provides all the code needed to add multiplayer functionality in a turn-based game.
- "Station" is a typical example of the use of MQTT, with several sensors sending their data back to a controller that can remotely activate or deactivate them.
- "Stress" subjects the broker to intensive testing with numerous clients and messages. This example compares the stability and processing speed of jMQTTBroker2 with those of jMQTTBrokerExtended.

The current version (2.1) is based upon Moquette v0.14.3 by Fraunhofer IOSB.

You need an additional file (moquette-0.14.jar) for this library.

I tried to Run the Client B4a Project and ran into the following error. I did install B4A 10.0 earlier today. I don't know if this is the reason.

warning: Ignoring InnerClasses attribute for an anonymous inner class
(org.apache.log4j.chainsaw.ControlPanel$1) that doesn't come with an
associated EnclosingMethod attribute. This class was probably produced by a
compiler that did not target the modern .class file format. The recommended
solution is to recompile the class from source, using an up-to-date compiler
and without specifying any "-target" type options. The consequence of ignoring
this warning is that reflective operations on this class will incorrectly
indicate that it is *not* an inner class.

With B4J / java 11.0.1 the Broker_Authenticator always return "true" but but I always get following message o_O

It's difficult to try code with missing parts (I don't know how act and pwd are loaded) but at first glance, your code should return false when the user is unknown or the password is wrong. I don't know why your code gets an error. Without a project to try, I can't tell.

Two files are missing to try your project (jystring.bas and comparators.bas). Since the problem may come from the value returned by jystring for act and pwd, you should test them:
B4X:
        s1 = jyString.ValueKeyInArray(Args,0,"act","=")
        If s1 <> "" Then
            act = s1
        End If
        s1 = jyString.ValueKeyInArray(Args,0,"pwd","=")
        If s1<>"" Then
            pwd = s1
        End If
        Dim Username As String = "1234"
        Dim Password(4) As Byte = Array As Byte(65, 65, 65, 65)
        If Username=act And BytesToString(Password,0,Password.Length,"ASCII")=pwd Then
        ...
        Else 'Expected result
        ...
        End If
