If you use Adobe Flex Web applications that connect to Plain Old Java Objects on the server side, chances are you use a popular, robust, and freely available server called Apache Tomcat. If you use Eclipse-based Flex Builder, you can smoothly debug both Flex and Java code without leavi...
Recently I had a chance to chat with Maher Masri, the CEO of Genuitec, the company that offers the Eclipse-based Java IDE called MyEclipse. My goal was to find out why would I want to purchase this IDE if free Eclipse fits the bill for most of the developers.
