Summary These 3 messaging technologies have different approaches on building distributed systems : RabbitMQ is one of the leading implementation of the AMQP protocol (along with Apache Qpid). Therefore, it implements a broker architecture, meaning that messages are queued on a central node before being sent to clients. This approach makes RabbitMQ very easy to use …

I have a couple of quick notes for any aspiring java architects. Please read them carefully and think about them. Adding layers is BAD In general, you don’t need extra layers until you need them. At that point, add a new layer (but only in necessary places). Create “standard” layers just adds complexity, makes maintenance …

Create a deploy.last directory inside the jboss deploy folder, and put non dependent applications into deploy folder root. This way dependent application will deploy at the end. Jboss Recipe

In last article, we have reviewed various SMPP based simulators which can be used for to simulate as SMSC or USSDC behavior. So, in this article we are going to in list and explore the various Java based SMPP libraries to connect with any simulator or any real SMPP supported SMSC or USSDC. jSMPP This is complete & full …

Recently, I have chance to heavily R&D on telco stuff like, connecting with SMSC & USSDC via SMPP protocol. USSDC can use SMPP, CIMD or propriety protocol for USSD Service application. The most complex and challenging thing is the access to the gateways when you are developing the application integration part. I have got some very good SMSC & USSDC simulator which I used at development time for debugging and then at production mode …
