Hi Mohanbabu,
I would be interested in your example :)

voila!! I have figured it out.
I was trying on the same lines as Mark explained. Then I added database
connection settings (driver class,DB URL, username,password,schema,etc)
in hibernate.cfg.xml and added the hibernate jars. Then , create a
connection factory and used a simple DAO code, to read and write to
DB2.
I'm getting started on writing the "real" implementation of
IoHandlerAdapter. Let's see where it takes me.
Thanks everyone for your input. I'll create a simple application as an
example. If anyone is interested, please let me know.

Being a MINA newbie, I may be off here. If you look at the EchoServer
example code :
http://svn.apache.org/viewvc/directory/trunks/mina/examples/src/main/java/org/apache/mina/examples/echoserver/Main.java?revision=400068&view=markup
You see the line :
acceptor.bind(
new InetSocketAddress( PORT ),
new EchoProtocolHandler(),
config );
This function takes in an instance of EchoProtocolHandler. This class
is what actually performs the processing of the data. In your
application, you would write a class that extends IoHandlerAdapter,
and in your messageReceived method, you would perform the database
insert.
Again, I am new to MINA, but I have not seen anything that leads me to
believe that there is special database backend support for the server
side. This is up to the end developer to create the customized class
to perform the database updates.

yes, I agree.
I guess my question is this: After I do the client-server thingy
with
MINA, how do I store it in DB?
Atleast, MINA needs some interface to database, right? May be , my
problem has nothing to do with core-MINA code but a new interface or
layer ?
please let me know If I'm incorrect and what do you think.
thaks for your reply,
Babu

My view of MINA is that it has nothing to do with persistence at
all.
Just receive the messages and process them with any Java-API you
want.
MINA
is only the client-server part and shouldn't be mixed up with
persistence (like QuickServer does it for example).

Hi developers!
We are writing a simple MINA implementation to receive XML
messages
from devices and store in it a DB2 / MySQL database (thousands of
devices sending XML in few seconds - still in design). I'm very
new
to
MINA and would like to know how to interface with databases.
1. Is there any XML parser - tried and tested - which may be
inbuilt
or coupled with MINA? (I read some XML codec is under development)
2. How to do database stuff? Is there anyone who has tried
integrating
MINA with DB? (using JDBC/ Hibernate)
3. How about connection pooling,exception handling, etc ?
4. Do I have to write an all-new MINA-database persistence layer?
or
All my questions
If some design just flashes in your mind, please let me know. A
step-by-step guide would be great. Any advice / help is greatly
appreciated.
You guys are doing a great job and I'm more than happy to
contribute
anything I can.
thanks
Babu
