MyEclipse converting Eclipse Project does not start problem

A dynamic Web project developed in MyEclipse is introduced directly into Eclipse to continue development, and a warning is issued when you start Tomcat, and the more serious problem is that the project you want to start does not know where to go, without reading the configuration file:

      warning: [Setpropertiesrule]{server/service/engine/host/context} Setting Property ' source ' to ' Org.eclipse.jst.jee.server:XXXXXXX ' did not ' find a matching property.The reason is very simple, because the default Web resource root folder name of the two compilers is not the same, naturally there is no project path can not find the problem, when you want to normal startup only need us to manually modify the root folder name, can be done in the compiler, as shown in the following process: first open the project properties, if the Dynamic Web project is introduced as a normal Java project, you need to first modify the Web project, such as: 
Once you're sure, you'll see the conversion in eclipse to a dynamic Web project, and then continue with the properties, such as: Remove the original default root folder directly, click Add (Add a new folder name) and select an existing folder directly after next. Finish and then redeploy start Tomcat project to start normally ... But the above warning still exists, who solved the problem can leave a message ha, thank you.
