Starting with version 5.13.0, ActiveMQ supports wire format protocol detection.   OpenWire, STOMP, AMQP, and MQTT can be automatically detected.  This allows one transport to be shared for all 4 types of clients.

Enabling AUTO over TCP

To configure ActiveMQ auto wire format detection over a TCP connection use the auto transport prefix. For example, add the following transport configuration in your XML file:

     <transportConnector name="auto" uri="auto://localhost:5671"/>

Enabling AUTO over SSL

To configure ActiveMQ auto wire format detection over an SSL connection use the auto+ssl transport prefix. For example, add the following transport configuration in your XML file:

     <transportConnector name="auto+ssl" uri="auto+ssl://localhost:5671"/>

• For more details on using SSL with ActiveMQ, see the following article (How do I use SSL).

Enabling AUTO over NIO

To configure ActiveMQ auto wire format detection over an NIO TCP connection use the auto+niotransport prefix. For example, add the following transport configuration in your XML file:

     <transportConnector name="auto+nio" uri="auto+nio://localhost:5671"/>

Enabling AUTO over NIO SSL

To configure ActiveMQ auto wire format detection over an NIO SSL connection use the auto+nio+ssl transport prefix. For example, add the following transport configuration in your XML file:

     <transportConnector name="auto+nio+ssl" uri="auto+nio+ssl://localhost:5671"/>

Configuring AUTO Transport Options

There are some configuration options that can be set.

An example that configures the transport with a maximum protocol detection time of 5 seconds:

     <transportConnector name="auto" uri="auto://localhost:5671?protocolDetectionTimeOut=5000"/>

Configuring Wire Formats

OpenWire is the default Wire Format that ActiveMQ uses.  It provides a highly efficent binary format for high speed messaging.  OpenWire options can be configured on a JMS client's connection URI string or on a Brokers transport bind URI.

An example of a property that applies to all formats:

     <transportConnector name="auto" uri="auto://localhost:5671?wireFormat.maxFrameSize=1000"/>

An example of a property only applied to OpenWire would be:

     <transportConnector name="auto" uri="auto://localhost:5671?wireFormat.default.maxFrameSize=1000"/>

Configuring Enabled Wire Protocols

By default all wire protocols are available.  This can be configured to only enable certain formats by setting the property  auto.protocols. 

An example showing only OpenWire and STOMP enabled:

     <transportConnector name="auto" uri="auto://localhost:5671?auto.protocols=default,stomp"/>
