Just had 5 year anniversary.  IBM contributed the original code – worth $40 million  OTI developed dev environment for Smalltalk which was licences to IBM under the name Visual Age.  Visual Age for Java was then developed then rewritten in Java to form basis of Eclipse  Sun Microsystems wasn't happy about it. Copyright © 2006 Eclipse Foundation, Inc., Made available under the Eclipse Public License v 1.0 13 Brief Sidetrack on History  The SWT and Jface libraries are an alternative to Sun's AWT and Swing.  SWT and Jface give native look and feel and allow access to native widgets.  They're more resonsive than Swing but less portable.  Borland, IBM, MERANT, QNX Software Systems, Rational Software, Red Hat, SuSE, TogetherSoft and Webgain formed the initial eclipse.org Board of Stewards in November 2001.  On Feb 2, 2004 the Eclipse Board of Stewards announced Eclipse’s reorganization into a not-for-profit corporation.
