Hi all, I have a service which needs to run on multiple machines picking jobs off of a single queue ensuring each job is only undertaken by a single service. I also need to publish messages for all services to receive, such as reload triggers. Is this possible in nservicebus without too much hacking? I have proved that both the publis...

Hi, In Comet/Reverse Ajax/PubSub underlying technology/fundamental is Long polling. So connection is kept open for a minute or so.. And as per my little knowledge about networking and OS, TCP/IP supports only 65535 ports, so my question is how any server can support more then 65535 connections concurrently? In application I am building...

I'm looking for something open source that can "push" messages to connected clients based on their subscription, for example "User 1" might be subscribed to "feed1" and "feed3" and "User 2" might be subscribed to "feed2" and "feed3" etc. I've got something working using ejabberd but it requires that the server send a message individual...
Suppose I have no network card installed on my computer, and I would like to have functionality similar to the following: Process 1 will publish messages to some URI, say "Uri1" var publisher = new Publisher("Uri1"); publisher.publish(new Message("Somedata"); Process 2 will both listen for messages on "Uri1" and publish messages to "...
What are my options for pubsubing (or point to point but pubsub is better) messages to and from an IBM message broker from an embedded headless C/C++ linux client that doesn't have a JVM? Ideally we want large file transfer (2GB once per day off of the client) encryption (SSL) reliable ('assured' delivery / QoS2, maybe QoS1 would do) ...
I want to develop a proof of concept WCF pub-sub service that should hold thousand of users and a lot of publications (stock rates). has anyone has experience which such kind of service? can it hold real time apps? does anyone has a sample for high performance WCF pub-sub? ...
Hi. I'm getting started with NServiceBus and have a question about the Pubsub sample. My intention was to have multiple instances of Publisher1 running and receiving the message sent from the publisher. I also hacked the Publisher to only send messages of the eventMessage type. But if I start the publisher and three instances of Subscr...
Hi guys, I am new to Openfire and XMPP and there are a few things that are a bit unclear to me. I would like to use pubsub to notify all the subscribers when new blog post is published on the website. Subscribers should be able to receive these notifications through their IM applications of choice (Adium for example). The problem is tha...
I'm currently using Retlang for message-based multithreading in .NET, which is a great library. I've got no explicit locks anymore, every thread is doing its own business, managing its part of the application and communicating with other threads via messages. I now have to implement a feature of my application that could also have its o...
Ok, Quick background We're using NServiceBus 2.0 with pretty much the standard config, nothing "crazy" going on. App is .NET 3.5 Dev environment is Publisher and Subscriber are on the same box, Windows 7. Staging environment is Publisher and Subscriber are on different boxes, one Windows 7, the other Windows Server 2008. Behaviour ...

Hi, I have a web app where users can follow one another. When one user publishes some action, I'd like that action to appear in the feeds of followers. A simple approach might be keeping a feed.xml file for each user, which is updated like: UserA is followed by UserB, UserC. UserA publishes some content. Update UserB, User...
Hi, Is there a good free service bus for .Net that allows subscriptions from Java clients? I'm working with NServiceBus and I like the fluent API and the simplicity, but it doesn't support Java clients or WCF integration for web-service based connections. Thanks! ...
We have an existing system that processes a lot of files on an ongoing basis. Roughly speaking, about 3 million files a day that can range in size from a few kilobytes to in excess of 50 MB. These files go through a few different stages of processing from the time they are received to when they are finished being consumed, depending on...

What is the best way of integrating node.js with Scala (Java)? The simplest way I see so far is using Redis PubSub as a mediator, with node.js server handling HTTP requests and publishing messages to the request channel (via redis-node-client), and Scala actors (e.g. Akka Redis PubSub integration) subscribed the request channel and publi...
