After you have created or obtained the Java class that implements your servlet’s functionality, and defined the servlet with a J2EE development tool, you can configure the properties that control how the servlet’s class is loaded and executed.
Some important differences regarding servlets in EAServer
version 6.0 and version 5.x:
You cannot add a new servlet to a EAServer 6.0 Web application using the Management console.
The preferred way to add a servlet to EAServer 6.0 is by using a J2EE development tool. Deploy servlets to EAServer using the deploy command. If you make changes to a servlet, you must redeploy it.
EAServer 6.0 does not support servlets outside a Web application.
