Currently using chronicle queue to store trade data. and want to use chronicle engine to share over network.

with subscribe and publish serivice.

This suggests you have an error in your configuration file. Can you send us a copy of it?

The configuration file is actually deserialized. This means your configuration blocks need to be typed. In this case it needs to be typed as a class which implements Installable.
