Hi, I install a ColdFusion MX 7 Updater 2 in my ColdFusion Server but don't
work it.... my server has a Windows Server 2003 Enterprise and we are
developing an aplication in Flex 2 and we are using ColdFusion for connect
to data base but Flex 2 need a ColdFusion MX 7 Updater 2 to install Flex
Data Services Adapter - enabling the use of Flex Data Management Services
with ColdFusion components (CFCs). In Adobe web site
(http://www.adobe.com/support/documentation/en/coldfusion/mx702/cf702_i nstall.html)
are an instrucctions about install this updater, I follow this instructions
and install this updater correctly, check the existence of this files:
cf_root\lib/cfusion.jar
cf_root\lib/im.jar
cf_root\lib/wsdl4j-1.5.1.jar
cf_webroot/CFIDE/adminapi/Application.cfm

This instalation create a Flex folder in WEB-INF folder, this WEB-INF folder
is in CFusionMX7 directory in Inetpub. And everything is OK but in Flex
Builder 2, when I attempt to create a new project and appear a wizard window
and I select a project with Cold Fusion Remoting Sevice, in second step I
got to select a Root folder and send me an error window tell me that I got
