This time I give some recommendations about why and when to use Threads when handling OP_ACCEPT, OP_READ and OP_WRITE.  —  Jean-Francois Arcand

Unit testing remote access to JMX MBeans
I often want to test that my MBeans work correctly when accessed remotely. For example it's easy to accidentally introduce non-serializable objects in them. It's a pain to set up a real remote connection, but you can make a loopback connection in the same JVM to test most of the same things. Here's how.  —  Eamonn McManus

This blog gives two examples.  —  Cay Horstmann

A new technical paper describes the integration procedure of the open-source JasperReports framework into NetBeans and the report-generation process.  —  Marina Sum

Executing Tasks Portably at the Startup or Shutdown of a J2EE Application Server
Enterprise applications often need to execute some tasks at the startup or shutdown of the Application Server. Many application servers provide proprietary ways of doing this, but there is a standard portable way as well. In this blog, I will discuss how this can be done using the Servlet API.  —  Inderjeet Singh
