Plumtree Eases Custom Integration for Developers with EDK Extensions

      Solution for PeopleSoft, SAP and Siebel Integration Offers
     Superior Flexibility and Increased Return On Investment (ROI)

   Plumtree Software (NASDAQ:PLUM) today announced its Enterprise Web
Development Kit (EDK) extensions for integrating systems of records
such as PeopleSoft, SAP and Siebel. This kit consists of code samples
and templates to enable developers to rapidly create integration
portlet services with the user interface of their choice. In turn,
these portlets form service-oriented building blocks for creating
composite applications which can be delivered through the Plumtree
Corporate Portal.
   Unlike competing integration solutions which either have "canned,"
inflexible user interfaces or overwhelming development complexity, EDK
extensions provide useful starting points for building portlets
without placing any restrictions on the user interface. Plumtree's EDK
extensions help enable companies to unlock the true potential of
enterprise applications by tapping into the services and functionality
of their existing ERP and CRM systems. As a result, more users are
able to access these applications while organizations are able to
experience greater ROI from their enterprise system investment.
   Comprised of APIs, documentation and sample code, the EDK affords
developers the unique ability to build portlets and Web services for
the portal in both Java and .NET-based environments.
   "Plumtree's EDK extensions provide enterprise application
developers the blueprints for creating portlet based services to tap
into back-end systems such as PeopleSoft, SAP and Siebel," said Girish
Balasubramanian, product line marketing manager at Plumtree Software.
"Integration and service-enablement has always been a key strength for
us. With our open architecture, we empower enterprises to choose to
work with applications that are right for their business rather than
locking them into a single back-end vendor."
   The EDK extensions balance superior flexibility with
time-to-deployment by offering:

   --  SAP portlets for human resources and sales and distribution:
        update personal and customer information, create sales order,
        check inventory and view order status

   --  Siebel portlets for two key functions: view account and view
        and update opportunities

   --  PeopleSoft portlets for human resource management system: view
        paycheck information, update personal information, update
        dependent beneficiary information

   --  Portlet code for customization

   --  Documentation

   --  QuickStart guide for installation and configuration

   --  Support by developer support
