Hello All - Recently while browsing I came to know about MINA. I am a
Java/J2EE developer.
I am working in wireless broad band and networking company and I have
limited knowledge on networking domain.
In our company we manufacture Wireles switches, Routers and Access Ports
etc., And its softwares.
I would like to know How MINA will be useful and what kind of business
applications we can build using MINA.
Thanks in advance for the information.

Hi
I have no idea of the source of the problem.
Was working last time I tried. Perhaps it's a port opening problem ?

Julien,
Tried the MINA mapping. Its not working for me. It throws
java.net.PortUnreachableException exception.
Tried capturing packet, but no packets are sent. My agent simulator is
running on port 8001.
Here are the traces

Ok! Porting done to MINA 2.0 M6
Porting was easy. The thread didn't had answer to why an Agent need
access to Logger?
So, if we use MINA Transport mapping, we will definitely need SLF4J,
and that shouldn't be an issue :-)
Should I change this code
ConnectFuture cf = connector.connect(new
InetSocketAddress(getAddress().getInetAddress(),
getAddress().getPort()));
cf.awaitUninterruptibly();
to
for (;;) {
try {
ConnectFuture future = connector.connect(new
InetSocketAddress(
HetAddress().getInetAddress(),
getAddress().getPort()));
future.awaitUninterruptibly();
session = future.getSession();
break;
} catch (RuntimeIoException e) {
System.err.println("Failed to connect.");
e.printStackTrace();
}
}
Will test this tomorrow. Not sure if SNMP4J guys have any test suite for this
thanks

Yes I would be very keen on using this.
By any chance, do SNMP4J guys know about this? I read that they were
looking for porting their lib to NIO.
As I write this mail, I am integrating your code in SNMP4J code on my machine.
Once I am done, will definitely blog about this.

Perhaps you'll need to fix the code for use latest MINA 2, but it's
probably trivial.

Great work. I would love to use it. The most interesting part would be
to benchmark the two implementations.
A good topic to write about :-)

I developed a Trap receiver based on MINA, you can find it on the link
shared by Emm.
Since your are using SNMP4J, it leaves a little place for MINA, unless
you or SNMP4J folks intend to port transport layer to MINA.
However, if you building EMS/NMS layer, there could be couple of
useful things that you could do to create an application that scales.
You have a very good case for using Apache FtpServer (MINA sub
project), to collect mediation/performance data ftped by Devices.
The usages are unlimited, you just have to discover them.
We are here to help you out with MINA :-)
Good Luck !

Yes I am working on Java/J2EE enterprise application which manages all wirelss switches. In fact this applications discovers the switches by sending SNMP variables and discovers the switches. And also collects the data from switches. We are using SNMP4J API for the same.My knowledge is very limited on internals / about wireless switches I am a web applications developer.
Hope you can understand.
Hello Emmanuel Lecharny - Thanks for the link. I am trying to understand the different kind of business applications which were used by people on MINA.
Thanks
Chenna

I also find it a tad ironic that you work for a wireless broad band and networking company and claim that your knowledge of the networking domain is limited :-)

I have no idea. Do you have something more precise in mind ? Your
question is pretty vague at this point. A bit like "I have discovered
Java, and I want to know what kind of business applications I can build
using this language..."
In any case, reading http://mina.apache.org/testimonials.html could give
you a clue about what people are using MINA for.
