For example, if you wanted to change the 'tcpNoDelay' property of the NioSocketAcceptor's nested SessionConfig instance: ... ... Naturally the default,no-arg constructor of whatever bean you're instantiating must ensure that any beans referenced via a OGNL expression are non-null (the NioSocketAcceptor does indeed ensure this for its internal SessionConfig instance). No coding necessary :) Using the nested property technique above, I think you can easily satisfy almost all of your Mina Spring-configuration needs. Here is the Spring doco reference: http://static.springsource.org/spring/docs/2.5.x/reference/beans.html#beans-compound-property-names Regards, Les @Declan and Ashish,

One question that has been vexing me for the past while that you may know the answer to. Do you know why the reuseAddress session config parameter no longer exposed when configuring an NioDatagramConnector/Acceptor ? Of course it is possible to set it programmatically by getting a hold of the DatagramSessionConfig from the acceptor/connector once created, however it makes it awkward from a spring config point of view.
