LC ES Developer Express version 1.1 has been released and brings with it support for LiveCycle ES 8.2.1 running on Microsoft Windows 2003 Server Enterprise Edition within Amazon EC2, using JBoss 4.2.0 and Microsoft SQL Server 2005 Express.
The Windows-based virtual instances of LiveCycle ES are configured with all of the same features as the existing RedHat Linux-based virtual images, including support for BAM, ContentSpace, and PDF Generation using OpenOffice.
