VMPIPE and IPC
1. Can i use VMPIPE for implementing ipc between to separate java process
applications?
2. Can VMPIPE be use in a production application, for decoupling the
connectivity layer from the business layer? In other word have a process for
received the connection from the outside and business process for
processing the transaction, an both process establish a connectivity using
vmpipe.
Regards
Angel Figueroa

I feel deeply sorry to make you feel so uncomforable. MINA benefited me a
lot, however basically i am just
a naive USER of MINA(I only read tutorial, examples and make a server)
Sometimes I also feel sorry to myself since I can only be a user but not a
contributor due to lack of programming skill and no time to
read the all source code. However, I also tried to give some suggestions to
this maillist with my limited knowledge and tried to answer some questions.
Why I asked such a STUPID question because:
>From the example:
SocketAcceptorConfig cfg = new SocketAcceptorConfig();
cfg.getFilterChain().addLast("codec", new ProtocolCodecFilter(new
SumUpProtocolCodecFactory(true)));
acceptor.bind(new InetSocketAddress(SERVER_PORT), new
ServerSessionHandler(), cfg);
I thought that was the one way to configure a filter(need a
xxxAcceptorConfig). But i can't find a corresponding VMAcceptorConfig in
the API.
I will think more before I raise a question.
Thank you.

In 1.x:
VmPipeAcceptor acceptor = ...;
acceptor.getDefaultConfig().getFilterChain().addLast("executor", new
ExecutorFilter(...));
In 2.x:
acceptor.getFilterChain().addLast("executor", new ExecutorFilter(...));
Now here comes some rant...
I am really sorry to say this to you, but how could you ask this kind
of question considering that you already know how to add a filter to
other transports such as socket? You have been participating in this
mailing list for a long time and now you are behaving like you don't
know nothing about how to add a filter. It's too trivial to answer
and simply wastes other community members' time. Are you sure you
really didn't know how to do that, or just didn't want to try a few
lines of code by yourself but copy-and-paste?
I don't want to discourage anyone in the mailing list, but I sometimes
get really discouraged by this kind of post. Yes, myself really loves
this project and I spend much more than so-called full-time for this
project - every day and night literally. I hope you understand my
feeling at this moment and what discourages the committers who spends
enormous amount time for their little baby project.

Yes. Insert an ExecutorFilter to the filter chain like you did for
other transports.

If you have direct access to the server business logic, you can call
it directly rather than via vm-pipe.
But, if your applications highly depends on MINA and they want to
communicate with each other, you could use vm-pipe.

The purpose of VM pipe is only for testing? I don't quite understand "the

You can drop ProtocolCodecFilter, which means you save a lot of CPU
time. Therefore, the performance will be much better, but not better
than the direct invocation.

One Java virtual machine means one process. Do you mean two java
application (or thread) in the same virtual machine? If I guessed
correctly, yes you can exchange data without opening a socket with
in-VM pipe transport.

IF the two java process are executing on the same java virtual machine, it
meaning that they can no establish communication or Only in the context of
the same process executing on the same vm.?

May I know what is VMPIPE?
I'm not able to find good explaination from Google though, and many
results are related MINA.
