Centralized application logging server, logFaces reached its version 2.5 release this month. With its own embedded database, logFaces creates a central point for the collection of log data from applications running on multiple machines.<br><br>This release brings with it notification triggers, an asynchronous appender with a failover mechanism, and user interface enhancements for filters, drills and queries. In addition, logFaces 2.5 provides an API for programming your own handlers. <br><br>The product supports a log4j.dtd compliant, format which can be used with log4j, logback, log4net, log4cpp, slf4j and any other framework using this format.

One common comment we hear when talking about JRebel is that class updates should be implemented in the standard JVM (see <a href="http://www.zeroturnaround.com/jrebel/comparison/">feature comparison</a> and <a href="http://www.zeroturnaround.com/blog/reloading_java_classes_401_hotswap_jrebel/">behind-the-scenes notes</a> to find out more about JRebel and HotSwap). However even if Oracle or IBM would announce tomorrow that they implemented the support for full schema change HotSwap in the next version of the JVM, JRebel would still be a worthwhile investment. Why?<br><br>There are 5 major features that are impossible to support in the JVM:<br><ol><br><li>Adding new classes</li><br><li>Changes to resources</li><br><li>Changes to web resources</li><br><li>Caches</li><br><li>Managed Components (EJBs, Spring beans,...)</li><br></ol><br><br>We solved them like this:<br><a href="http://www.zeroturnaround.com/blog/5-jrebel-features-you-couldnt-do-in-the-jvm/"><a href="http://www.zeroturnaround.com/blog/5-jrebel-features-you-couldnt-do-in-the-jvm/" target="_blank">http://www.zeroturnaround.com/blog/5-jrebel-features-you-couldnt-do-in-the-jvm/</a></a>").substring(0,300); return _diggURL ; } One common Click Here to read more...

NoSQL describes several database technologies for which the data stores don't need a fixed schema and often avoid join operations.
