Note: The following instructions use the term lcds_install_root to refer to the installated home directory for LiveCycle Data Services ES 2.6.1. 1) Shutdown your ColdFusion 9 server if its running. 2) Copy the ColdFusion9/lib/flex-messaging*.jar files to a backup location. If you are running a multiserver instance or a J2EE installation, these files are in the WEB-INF/cfusion/lib directory. 3) Copy the lcds_install_root/resources/lib/flex-messaging*.jar files and overwrite them into the ColdFusion /lib directory. 4) Copy "LCDS2.6.1_for_CF9/WEB-INF/flex/jars/cfdataservicesadapter.jar" to ColdFusion WEB-INF/flex/jars. 5) Also Copy the following SWC libraries from lcds_install_root/resources/frameworks to the CF9 directory: ï /libs/fds.swc file to the /WEB-INF/flex/libs directory ï /libs/player/playerfds.swc file to the /WEB-INF/flex/libs/player/ directory ï /locale/en_US/fds_rb.swc file over the /WEB-INF/flex/locale/en_US/ directory Old Style(CF8 style) Flash Remoting steps ========================================= 6) Copy your CF8 WEB-INF/flex/ *.xml config files to ColdFusion 9 WEB-INF/flex/ folder 7) Start ColdFusion server. Enhanced Flash Remoting of CF9 steps ==================================== 6) copy *.xml files from LCDS2.6.1_for_CF9/WEB-INF/flex directory to ColdFusion 9 WEB-INF/flex/. 7) If your LiveCycle Data Services applications use RTMP channel, open the ColdFusion WEB-INF/flex/services-config.xml file and uncomment "cf-rtmp" channel. By default it is commented. 8) If your old Channels( in service-config.xml) has the present under xml tag, then either remove , or set it to true. Also set the to False. 9) Add your data management destinations from the old file to the new data-management-config.xml file. In ColdFusion 9 release, there are few changes in the destination and channel structure due to changes in the serialization process. The following properties have been moved from destination to channel level. You need to move these properties under --> --> from your For details, see "Changes in the XML configuration files for New Flash Remoting" in ColdFusion 9 Documentation. 10) Deploy your LCDS/Flex applications after recompiling them using new *-config.xml files, which has above mentioned changes 11) Start ColdFusion server.
