JBoss Messaging was designed and built from the ground up and was not based on the JBoss MQ architecture and is 100% JMS Compliant The main new features are related to clustering functionality. JBoss Messaging contains a fully functioning and ... [More] highly scalable clustering implementation. Unlike JBoss MQ, JBoss Messaging does not rely on a "HA Singleton", this was a major drawback in JBoss MQ, where only one JMS server in the cluster was active at any one time, providing a scalability bottleneck. With JBoss Messaging this limitation disappears and all nodes in the cluster can simultaneously host active JMS servers allowing the load to be distributed much more smoothly. [Less]

Java Simon - Simple Monitoring APIJava Simon is a simple monitoring API that allows you to follow and better understand your application. Monitors (familiarly called Simons) are placed directly into your code and you can choose whether you want to ... [More] count something or measure time/duration. Access to Simons is provided via static SimonManager. You may want to check our Examples. News!October 2nd, 2008First release of Java Simon is pretty close, because we are nearly finished with all basic (and some not so basic) things we wanted to have: Simon core, monitors, stopwatch, counter, SimonManager; declarative Simon configuration; JDBC proxy driver and DataSource implementation (v3). We want to finish some prettification and documentation and after some tests we'll be proud to present our work! MotivationWe wanted to use something like JAMon for our products originally, but we lacked two important features: better way (or any way for that matter) to organize all those monitors; nanosecond resolution. Monitor hierarchySimon API gives you a better control over all those monitors in your big - possibly Java EE - application. Simons are organized in a hierarchy similar to what you can see in java.util.logging API. Simons can be disabled which minimizes their overhead influencing your application. These operations can be performed on the whole subtrees of Simons which makes partial application monitoring easier. See SimonHierarchy for more. The time for nanos is hereSimon measures times in nanos - and believe it or not it can make the difference on current very fast machines. Although not all platforms provide timers precise enough this design decision is future proof. Of course this decision comes with a price - you can use Java Simon only with JDK 1.5 or higher (platform Java SE 5). See SystemTimersGranularity page for more. Future plansOur future goals include (the later goals are in a more distant future): JMX access to Simons, their values and enable/disable features. Sampling, collecting, agregating with persistence backend (file/DB). VisualVM plugin. Dynamic profiling integration. [Less]
