The Web Application Name is the display name used on the server to identify a deployed WAR file.
Use the description box to provide any information that might be required by the consumer of the application.
Session Timeout is a specified time in minutes after which the server will terminate servlet sessions. This value applies to all the servlets within an application. A value of 0 indicates that servlet sessions never expire.
Web applications can run on only one Java VM at any one time. To override this rule, you must mark the Web application as distributable in the deployment descriptor. However, the application must conform to additional requirements. A distributable Web application cannot use setAttribute and putValue methods to place objects into a javax.servlet.http.HttpSession object unless the object is one of the following types:
java.io.Serializable
javax.ejb.EJBObject
javax.ejb.EJBHome
javax.transaction.UserTransaction
javax.naming.Context object for the java:comp/env context
For more information, see the Java Servlet specification, available.
