We updated the Installing and Deploying LiveCycle ES2 for JBoss (Single Server) guide recently to capture how to configure the JBoss Application Server to run as a service on Windows Server 2003 and 2008. While free tools to achieve this for 32-bit Windows/Java environments have existed for a while, you can now use the JBoss Web Native Connector for both 32-bit- and 64-bit environments.
We also updated the Prepare to Install/Upgrade LiveCycle ES2 documentation. The revised guides now explicitly mention support for JBoss Enterprise Application Platform (EAP) 4.3, besides JBoss 4.2.0 and 4.2.1.
You can download the latest PDFs from the LiveCycle Developer Center.
