The Art of (Visual) Composition (Windows 2003 server web) One of the
The Art of (Visual) Composition One of the more frequently asked questions directed to the Eclipse development team was if and when a visual GUI editor would be available for Eclipse. Eclipse 2 SDK did not provide a visual editor, but after a while several third-party GUI editor plug-ins appeared on the market (see Appendix A). Then, at Christmas 2003, eclipse.org released the first version (0.5) of the Eclipse Visual Editor for Java (VE) that, initially, supports only the design of Swing GUIs under Eclipse 2.1. In May 2004, VE M1 was released for the Eclipse 3 platform. Support of SWT GUIs is planned for version 1.0. What s nice about this tool is that it is completely free and that it is Open Source. But this is not its only advantage. The VE has like Eclipse its roots in Visual Age, despite the fact that it was implemented from scratch in Java. One of the main features of the VE is that it supports two-way programming: changes in the visual layout appear immediately in the generated Java code, while changes in the Java code are reflected back to the visual layout as soon as the source code is saved with Ctrl+S. With this feature, the VE completely refrains from using metadata but derives all information from the source code. Installation In this task the VE relies on the facilities of the Eclipse Modeling Framework (EMF). Therefore, before installing the VE, you must install the EMF. The EMF can be downloaded from www.eclipse.org/emf/. To install it, just unpack the downloaded archive into the /eclipse root directory. Then start the Eclipse platform and follow the instructions of the Update Manager. After restarting Eclipse, you can install the VE in the same manner. The VE download can be obtained from www.eclipse.org/vep/. 3

For example, TCP/IP is a connection-oriented protocol, with the virtual circuit ID consisting of source and destination IP addresses and port numbers. However, there are also unreliable protocols that are connection-oriented as well. These include ATM and Frame Relay, on which 90% or more of all Internet traffic is passed.
