RE: Asynchronous Http Client donation
Hi, I am sorry if this reply is not exactly what you may be expecting back. I am sure around here there are many experts that will have many more interesting replies then this one. However could you please explain to me (and possible others) what Asynch[ronous] Http Client is, and what are its advantages? If I know exactly what it is then I can imagine ways on how to use it :) Thanks and Regards, Sim085 From: Jeff Genender [EMAIL PROTECTED] Reply-To: [EMAIL PROTECTED] To: dev@mina.apache.org Subject: Asynchronous Http Client donation Date: Fri, 17 Aug 2007 20:19:07 -0600 Hi, First, I want to say that I am a big fan of Mina. For those who don't know me (which is everyone), I am a committer on Geronimo and have had several people ask about an async http client API to use with our NIO clients with comet for the 2.0 Geronimo server. We have had folks who want to be able to do HTTP calls to 3rd party servers from servlets/web apps to get content, and not tie up a thread while its doing its thing. So I decided to try to whip together an API that was similar to Commons HttpClient, fully asynchronous, but based on Mina...and I think I have 80-90% of it completed. It is here: http://svn.apache.org/repos/asf/geronimo/sandbox/AsyncHttpClient For what it's worth...it doesn't seem appropriate for Geronimo. So I would like to donate it to Mina. Please have a look at it and give me feed back for if I have gone down the right path. It can be enhanced greatly as this is just a start, but I think it can be very useful and become a powerful API with everyone moving to NIO. Don't hold back any comments ;-) I would really like to see an API like this and I believe Mina is just perfect for this.

This could significantly throttle the throughput of the NIO containers. By having an Async Http Client API, the thread could be parked and put into use for something else while the original call is waiting for a connection or a response from the third party server.

Re: Asynchronous Http Client donation
I will have some free time in the next week or so. I can take the lead on incorporating this into the baseline, if someone wants to give me a good recommendation as to where to place the code. My initial thought is to create a new top level project inside of the trunk. Maybe mina-asynch-httpclient ?

Deciding on a protocol, need help

Re: Deciding on a protocol, need help
I'm creating a client/server learning management system. It will involve everything from passing objects to multimedia audio/video. I need some kind of control structure to pass requests to different services on the handler. I was just creating a main handler and having it call an array of services. But none of this is set in stone. I'm really just learning it. An example would be a student logs in and a request if made for the list of courses this student is enrolled in. So my server would return a list of Course objects to the client. So I have to have a way to route requests to the proper services. I started to create a action class that just extends a hashmap that way it was abstract enough to used on future version. Like JMS message class. Does any of this make sense? I'm sure others deal with this issue all the time. I even thought about just copying the JMS message class.

Re: Deciding on a protocol, need help
I'll give you my opinion based on your description. Or course, this is only one of the various ways you can implement your project. It would be awesome that other members of the list provide their own implementations so we can compare. I'm creating a client/server learning management system. It will involve everything from passing objects to multimedia audio/video. I need some kind of control structure to pass requests to different services on the handler. This could be implemented as a rich Internet page. Of course you will need a web interface (which you said you don't want) but this way it's already available and ready for you to put together.

So I have to have a way to route requests to the proper services. This is normally implemented as a page. You can make this a standard web service using SOAP (which relies on HTTP itself) and make it available for every kind of client, be it or not a web based one.

Re: Deciding on a protocol, need help
Ya, I've written web applications for many years, using many different frameworks. I looked at the XFire approach, but I find it a very heavy stack. However I've never used it so I can't say for sure. Mina just seemed like a very fast and flexible framework, being a network framework for applications.

I have loved REST for a long time. It solves a lot of real problems. One of my favorite things about REST is that it is easy to setup and test. I'm a big fan of testing, test driven design, etc. If you compare what you have to do to make a client for REST against Soap, there is no question which is faster to get working. I haven't looked at Restlet, but from a quick google, it sure looks worth considering. Pat -- Pat Farrell http://www.pfarrell.com/

I just did an update in Eclipse, and the problem still exists. -- ..Cheers Mark
Re: Deciding on a protocol, need help
Ya. I downloaded and tried it out some. Looks pretty good. But it does bring up a good question. Where does Mina fit when doing a project. Is there things it's better for over others? Is it something that's used to make servers or something that's used for client server. Is it LAN or WAN? Where does it fit?

I have loved REST for a long time. It solves a lot of real problems. One of my favorite things about REST is that it is easy to setup and test. I'm a big fan of testing, test driven design, etc. If you compare what you have to do to make a client for REST against Soap, there is no question which is faster to get working. I haven't looked at Restlet, but from a quick google, it sure looks worth considering.

Sure, look at the mina.apache.org # Unified API for various transport types: * TCP/IP UDP/IP via Java NIO * Serial communication (RS232) via RXTX * In-VM pipe communication * You can implement your own! If you restrict yourself to just using HTTP, your transport if locked. Mina is vastly more flexible, and for lots of stuff, you need it. For example, if you really want a UDP type service, don't even think about pushing that over HTTP, as HTTP is total overkill. Same if you want to use serial. -- Pat Farrell http://www.pfarrell.com/
