Isn't the idea of using a connector to embed the communication better in the
app server and give the appserver control? As I understand for inbound
communication the recomended way is to use a resource adapter together with
an MDB:

As for outbound, I don't know, what is better, direct socket communication
from an EJB or using a resource adapter. The latter seems to be more under
control of the appserver. 
I still like very much the idea of a resource adapter framework like
txconnect that allows you to easily plug-in your own low-lovel socket
communication. I found it very easy to create a client for the Unix datetime
service (see my posting

Unfortunately I only could get txconnect to work with Weblogic server, not
Geronimo (see my posting on dev).

Maybe an Apache project for a resource adapter framework were the right
solution ...
