Eclipse Tomcat is deployed, but the project folder is not found under Tomcatwebapps. __ Tool Configuration

Open the Services window and, if it is already open, do not need to open, if not on Window-> show View-> Servers

Then you can see your configured tomcat, double-click the Tomcate Service
Will come out a view of the tomcate configuration,
Select User tomcate installacion under service Location (the default selection is the first one)
Then save path selects your tomcat installation path, Deploy path chooses which folder you want to put the project in, preferably WebApps.

If you double-click to discover that the service location cannot be configured, you need to remove the project associated with the Tomcat server, and the right mouse menu clean clears the Tomcat server's status ^ ^ to be modified.

Then CRLT + S is saved. It's OK to redeploy.
