Tarantolato writes "The Eclipse Foundation has released version 3.0 of its open-source Java-based IDE. Eclipse backers like IBM say the program offers not only increased productivity and ease of use, but also a plugin-based architecture for creating 'rich client' applications with the networking capabilities of web-based apps and the persistence and native widgets of desktop applications. The Lotus Workplace platform is already Eclipse-based. Some in the Java community, however, are concerned with Eclipse's use of SWT rather than the standard Swing widget set, and some analysts think that project is part of a 'broader challenge to Microsoft's entire .Net development framework' from IBM. Meanwhile, Eclipse executives are attempting to woo Microsoft into joining the foundation."
