The most notable taker is EDS, which offers almost a dozen financial-calculation objects for sale on the site. It carries Enterprise JavaBeans, Component Object Model objects, Delphi objects, and Visual Basic objects. It also offers a source code escrow on products, so if the developer of an object you purchase goes out of business you can get the source, and a purchasing system so companies can buy objects via purchase orders rather than with credit cards or checks. It also offers white papers on how to create and document components properly for customers. Because many of the projects supported on Collab.
Net are open source, the buyer gets both the compiled component and the code.
Its sourceXchange marketplace allows developers to offer their components or bid on requests for proposals for custom programming jobs. Developers can comment on the sourceXchange message board on open projects, even if they don't participate. Net also hosts the NetBeans .org site, which is sponsored by Sun Microsystems. NetBeans is a modular integrated development environment written entirely in Java. It supports Java and other languages as well.
