Thread: [Beepcore-java-users] Help I'm drowning

I am doing vac work for a company who has asked me to look into the pros =

From what I have read about beep it is ideal for what this company is =

- What is the role of profiles?

Sean,

- What is the role of profiles?

A profile in the protocol sense is a description of the communication on a
particular channel. A profile with respect to the library is the code that
implements the communication on a particular channel.

- Once I have got a session up how do I make a connection from the Server to
the Client (implementing peer-to-peer)?

BEEP is bi-directional (peer-to-peer) so if you have a connection from the
Client (Initiator) to the Server (Listener) then either side can start a
channel as long as the other is advertising the requested profile.

- When a message is sent to the server, how does the server recieve the
message? I am guessing that it has to do with the profile, is that correct?

MSG messages are received by registering a MessageListener interface on a
channel.

I suggest you take good look at example provided with the kit
(Beepd.java and Bing.java). My responses are below your questions:

Profile is what you need to implement for developing your protocol on
top of BEEP. Usually all "interesting" work is in profiles. Read
BEEP spec for details. Although You will not find implementation details
of beepcore-java there.

You usually build a registry of profiles and register with the framework.

Typically, client initiates a session and then creates Channel with
desired profile. Use Channel to send messages.

Message processing at the receiving end takes place in your profile. Use
the Message object, given by framework to profile-methods, for replying.

Which message are you talking about? Connection requests are
processed using TCPSessionCreator. All other messages are usually
processed in profile.

> - Is beepcore-java the best java implementation to use?

This is something for you to decide. There are other implementations
available, such as beep4j, permabeep etc. I haven't seen much progress
on beep4j lately, although they claim that they are using a better
architecture (SEDA). You need to pay for the latter. Besides, beepcore-
java, if I'm not wrong, is the oldest of them (java implementations) all.

I realized it after seeing Huston's response that I failed to mention,
my assumption that Profile is implementing *Listener interfaces (
Message, Reply).
