Plumtree Software announced the Plumtree Corporate Portal 4.5WS, the newest version of Plumtree’s portal platform. Version 4.5WS completes Plumtree’s Web Services Architecture for bringing together electronic resources from Windows, J2EE and other platforms, integrating applications, federating searches, indexing content and authenticating users via Web services. Version 4.5WS also features enhanced search, with faster content indexing and less administration, and functional parity between the Windows and UNIX releases of the portal platform, which now share the same code base. Plumtree is announcing version 4.5WS in conjunction with a new Microsoft .NET development kit. In addition, two Plumtree partners are announcing the development of Web services for indexing content from Open Text Livelink and Stellent Content Management repositories. The Plumtree Corporate Portal 4.5WS is expected to be generally available on May 24.
