SSL-Based JMX Connections

If you need to have secure, encrypted connections between a JMX client and the broker's MBean server, then you need to configure both sides of the connection accordingly.

Broker Side SSL Configuration

As mentioned in JMX Connection Infrastructure, a broker is configured by default for non-secure communication using the preconfigured jmxrmi connector. Applications wishing to use the Secure Socket Layer (SSL) for secure communication must activate the alternate ssljmxrmi connector. The ssljmxrmi connector is preconfigured with imq.jmx.connector.RMIconnectorName.useSSL=true.

ProcedureTo Activate the SSL-Based JMX connector

  1. Obtain and install a signed certificate.

    The procedure is the same as for the ssljms, ssladmin, or cluster connection service, as described under Using Signed Certificates.

  2. Install the root certification authority certificate in the trust store if necessary.

  3. Add the ssljmxrmi connector to the list of JMX connectors to be activated at broker startup:

  4. Start the broker.

    Use the Broker utility (imqbrokerd), either passing it the keystore password in a passfile or typing it from at the command line when prompted.

  5. Disable validation of certificates if desired.

    By default, the ssljmxrmi connector (or any other SSL-based connector) is configured to validate all broker SSL certificates presented to it. Validation will fail if the signer of the certificate is not in the client's trust store. To avoid this validation (for instance, when using self-signed certificates during software testing), set the broker property imq.jmx.connector.ssljmxrmi.brokerHostTrusted to true.

JMX Client Side SSL Configuration

On the client side, if the AdminConnectionFactory class is being used to obtain a JMX connector, the AdminConnectionFactory object must be configured with a URL specifying the ssljmxrmi connector:

AdminConnectionFactory  acf = new AdminConnectionFactory();

In addition, if the JMX client needs to access the trust store, use the system properties and to point the JMX client to the trust store. For example:
