Configure Server Setting Issue in Flex 4.5

I am trying to Configure Server side Code in Flash Builder 4.5.I am Using LCDS 2.6.1.By clicking on validate configuration button I got message on top O开发者_JAVA百科nly Life Cycle DataService 2.6 and higher are supported.I am using 2.6.1.still not able to figure out the issue.Please help.

This version of LCDS works with Action Script 3.x so make sure your flex SDK is 3.5 in Flash Builder 4.X. Also make sure you have included the correct LCDS JAR files in your flex project.
