Hi,
Can MINA be deployed as an Inbound Resource Adapter (JCA 1.5) within a J2EE
container?
Some details on the scenario:
1. Through the new JCA 1.5 specification, we can now extend the "application
server" capabilities to make it act like a normal server accepting client
connections on TCP sockets (for eg. a telnet server can be implemented through
the application server). In short, this is achieved by writing a resource
adapter and deploying it in the J2EE container where the MDB (Message Driven
Bean) to implement the actual processing of the client connection is also
deployed. On receiving incoming client packets, the RA invokes the MDB and
hence the client requests are serviced. The RA thus deployed acts like a
connection manager for clients connecting to a particular TCP port, also taking
advantage of pooling mechanisms provided by the app server (since RA is
deployed within a J2EE container).
2. My question is, Can I use MINA so that it behaves like an inbound RA
deployed within the J2EE container so that it can accept client connections and
invoke the MDB deployed in the same container?
3. The problem I can see there is that the app server has its own pooling
mechanisms and MINA has its own pooling mechanisms. How will they work
together? Also, a resource adapter is required to adhere to some system
contracts making it use the facilities provided by the J2EE container. If MINA
is to be dpeloyed as the resource adapter, how will it implement the system
contracts?
I would be grateful to you if you can enlighten me in this regard.
Kindly Note: My question is NOT "How to make a resource adapter FOR mina so
that it can work with a J2EE component". Rather, I want to know whether MINA
can be deployed within a J2EE container as a resource adapter so as to provide
the above mentioned functionality.
Thanks and regards,
Vishal.
