Devops and RPM Distribution
Regularly deploying and provisioning RPMs is increasingly becoming a common need. With devops automating every aspect of deployment, including setting up new hosts in virtualized environments, packaging systems such as RPM are getting more and more important. Managed RPMs provide a great level of control over installations and easy upgradability.

One of the exciting things about teaching is the fact no matter how well you prepare for a class, events will always surprise you.Yesterday I was caught by surprise in the middle of a class by what seemed like a global Glassfish admin console outage.
I was teaching my Software Architecture students at IGTI how to change the default maximum thread pool size for the HTTP listener in Glassfish 3.0...

Google makes their extensive map collection available free of charge. Now it is seen in sites all over the web, but in this entry, I'll show you how simple it is to use in Java!

The www.abelski.com web site offers free (for personal and academic usage) courses about various topics in software development. The site focuses on Java technologies.

The Enterprise Architectures for Java EE Weighting Survey ends this Friday, June 25. Kate Jones of Oracle recently talked about the survey and its purpose...
Java EE Security refcard is available for download. This refcard covers Java EE 6 security and discuss how each application server supports the specs. The refcard covers authentication, authorization, and transport security in Web Application, EJB application and web services by introducing the concept and the related annotations and deployment descriptors which help us realize the concept.
Security
This a rather long article covering OpenESB (Open ESB) administration and management along with discussing a complete sample application shows how to develop solutions based on OpenESB
In this entry we discuss what Application Server Management Extension (AMX) and Java Management Extensions (JMX) are, how we can use them to develop custom administration, management and monitoring solutions for GlassFish v3. The article contains tens of diagrams and samples.
Research
Last week I gave a brief explanation of Web 3.0 and The Semantic Web to students at the college I attended more than ten years back. Possibly you are interested in the way Terminator and The Matrix will become real, then you should read on.
Programming
I'v just published an integration module for using GridGain with Spring Batch. Using this module you can distribute Spring Batch processing inside a GridGain grid with the implementation of remote chunking.
This is a relatively long entry about OpenMQ covering everything from installation up to clustering and load balancing. If you want to start using OpenMQ or you are looking to use it in a highly distributed system, this entry is for you. this entry discuss everything from installation to clustering

I am very fond of FindBugz (indeed it has found its way into the QA process of most projects I work on....). When visiting the site to check Eclispe 3.5.2 compatibility I found they were working on a new tool.
Education
A lot of applications these days title themselves RESTful. But how much REST is needed to be RESTful?
JSR
There is much discussion these days about HATEOAS (Hypermedia as the engine of application state) so it gets time to clearly say what HATEOAS actually means.
GUI
In my famous company innoQ I currently have the opportunity to work on a real cool tool: Bundle-Bee. It claims to be able to take any OSGi bundle and distribute the computational load to an ad-hoc grid (e.g. all machines in an office) without special setup or configuration.
We just released version 0.5.3 which is still very restricted and far from feature complete - we don't even...
Grid
This blog entry describes how WebSphere eXtreme Scale uses memory. This allows customers to better size how much memory they need when storing a large number of key value pairs in a grid.
