After reading the Macromedia's demo, I feel that Flex is a good thing, I decided to try it.
First download the Flex1.5 and Flex Build1.5 to find a computer installed Java 5.0SDK, Tomcat 5.5 installed Flex1.5.
Copy flex.war and other WAR files to the Tomcat directory, enter the address http: //. . . . Samples, haha appeared.
Install Flex Build1.5, as MM said, you can see the enhanced version of Dreamwaver. An MXML file immediately, published to Tomcat, depressed, invalid. I feel that it is Web-INF that is not configured, too lazy to distribute, released directly to Samples, OK
