NetBeans is more than an IDE - it is a full fledged platform for developing Java desktop applications. The NetBeans IDE uses libraries provided by the NetBeans platform that make displaying windows, handling events, and plugging in new modules much easier. Using these libraries can speed the development of interactive desktop applications. Interactive Network Technologies Inc. (INT) is a Houston based software company that provides graphical toolkits primarly for the oil and gas industry. It has migrated its geophysical data viewer, INTViewer, to the NetBeans platform. Customers can easily add modules to INTViewer as well as add custom features. We will take a look at developing applications with the NetBeans platform, using INTViewer as a case study.
