Click New Project, choose Java and Java Class Library. Click Next, then give the Project Name as server. Change the Project Location to DEVPATH\DevChat (DEVPATH, see above); the Project Folder is shown as DEVPATH\DevChat\server with DEVPATH being your chosen location. Check that Create Main Class is not ticked before clicking Finish.
