How do I synchronize my application sources on the server with their local copies in my IntelliJ IDEA project?
To debug an application on a remote web server, you need to have the copies of its sources in a IntelliJ IDEA project. To synchronize local and remote sources, create a deployment configuration as described in Creating a Remote Server Configuration and Configuring Synchronization with a Web Server.
Debugging an application
- Choose the newly created configuration in the Select run/debug configuration drop-down list on the tool bar and click the Debug toolbar button . The HTML file specified in the run configuration opens in the chosen browser and the Debug tool window appears.

- In the Remote URLs of local files area, map the files and folders to URL addresses of files and folders on the server according to the currently used deployment configuration, see Mapping local folders to folders on the server and the URL addresses to access them.
