By: Emiley J. : 2009-09-01

But the concept should be the same. So if you want to host some JSP files or servlets on your Tomcat which is installed in port 8080 and your IIS is installed on the same machine at port 80 and you want to direct all JSP files also to port 80 so that IIS can forward these queries to tomcat internally and respond.

By: Barbara : 2008-12-09

For example, if an object is defined to have page scope, then it's available only for the duration of the current request on that page before being destroyed by the container. In this case, only the current page has access to this data, and no one else can read it. At the other end of the scale, if an object has application scope, then any page may use the data because it lasts for the duration of the application, which means until the container is switched off.
