How can I configure a WSO2 Integrator FIX initiator endpoint which utilizes automatic session failover supported by Quickfix/J?

In Quickfix/J, it is possible to configure automatic failover of the initiator session using the FIX config file as follows (assuming two localhost FIX servers listening on ports 9997,9998)

[SESSION]

SenderCompID=SYNAPSE

TargetCompID=EXEC

SocketConnectHost=localhost

SocketConnectPort=9997

SocketConnectHost1=localhost

SocketConnectPort1=9998

ReconnectInterval=5

All examples in WSO2 documentation show FIX endpoints configured with a hardcoded host such as:

<send>

    <endpoint>

       <address uri="fix://localhost:9997?BeginString=FIX.4.4&SenderCompID=SYNAPSE&TargetCompID=EXEC"/>

    </endpoint>

</send>

This pattern is not possible for us because the target FIX server is on a remote server with a hostname that is different per environment, so I never want to hardcore the target host like this.

Ideally I would like to do something like this:

<send>

    <address uri="fix://<dynamic hostname>:9997?BeginString=FIX.4.4&SenderCompID=SYNAPSE&TargetCompID=EXEC"/>

    // the endpoint representing the above FIX Session

    // where the target host is dynamically defined

    // and not hardcoded anywhere in my car application

</send>

On the receiver/listener side as a Proxy Service this works fine, because in the proxy service it lifts the configuration from the supplied initiator config URL parameter, so the failover happens "under the hood" by the FIX engine.

<parameter name="transport.fix.InitiatorConfigURL">quickfix.cfg</parameter>

However it doesn't look like it's possible to do the same when you are sending a message to the target FIX server.

Does anyone have a good suggestion or an example for how to achieve this?

As you are using a normal 'address endpoint' you should also be able to use the normal failover configurations: see https://docs.wso2.com/display/ESB500/Configuring+Failover+Endpoints for info.
