Each nature brings set of properties to the project.For example a Java project has “src” directory and “bin” as build directory or you may want to associate a set of libraries to your custom project. Faceted Project Framework provides a powerful mechanism for extending the capabilities of the Web Tools Platform. Project facets are typically used as a way of adding functionality to a project. When a facet is added to the project it can perform any necessary setup actions such as copying resources, installing builders, adding natures, etc. Facets can also be used as markers for enabling user interface elements. This post explains defining a facet and using it. Prerequisites : Install WST eclipse plug-in Add dependencies to MANIFEST.MF Manifest-Version: 1.0 Bundle-ManifestVersion: 2 Bundle-Name: Sample Bundle-SymbolicName: com.facet.sample; singleton:=true Bundle-Version: 1.0.0 .qualifier Bundle-Activator: com .facet .sample .Activato...

Every eclipse plug-in or eclipse based products needs to provide custom editor for editing proprietary resources. I am tried to put important parts of Eclipse Editor Framework in this pos.

As explained above, new interface java.nio.file.FileVisitor has been introduced for traversing the file system. It has methods like preVisitDirectory(), postVisitDirectory() , visitFile () etc to give control to programmer to do any specific task while traversing/visiting the file system. A concrete  implementation java.nio.file.SimpleFileVisitor has been provided those don't want to provide implementation for all of the methods from java.nio.file.FileVisitor . Here is simple example using these new classes.   package com.test.jdk7; import java.io.IOException; import java.nio.file.FileVisitResult; import java.nio.file.Path; import java.nio.file.Paths; import java.nio.file.SimpleFileVisitor; import java.nio.file.att...
