Servlets are run in a web server. The servlet can be deployed to the web server as part of deploying your project, in MyEclipse, and the web server can be launched from MyEclipse. You can also get MyEclipse to launch the web server and bring up an internal browser directed at your application on the server. But this is all standard stuff; is there something specific you want to do that is not covered in the MyEclipse help?
