Error logging--invalid root. The Web-infflex folder must contain either Flex-config.xml or Services-config.xml

Error: Invalid root. The Web-inf/flex folder must contain either Flex-config.xml or Services-config.xml.

Configure Java Server (configuration of Java-EE servers),
It is obvious that you must start server tomcat first, or you cannot find the server path. Remember to copy the files in the Blazeds.war file Flex and Lib to the project's Web-inf directory, which is in the Blazeds/web-inf directory. You can then configure it in the following format:

For example, a project named Flexcrm.
Root folder:e:/Learning Class/tomcat/tomcat5.5.25/webapps/flexcrm
Root url:http://localhost:8080/flexcrm/
Context Root:/flexcrm
Output folder:e:/Learning Class/tomcat/tomcat5.5.25/webapps/flexcrm/flexcrm-debug

Configuration explanation:
Root folder: Path to project deployment on the server
The boot path of the Root Url:tomcat server
Context Root: Compiled Flex file save path
Output folder: Export path of flex file after engineering reconstruction

Then click the Validate Configuration Verify configuration button to display the Web root folder and root URL are valid. No more errors, OK.
