In Java Platform, Enterprise Edition, a web container "implements the web component contract of the J2EE architecture".[1] This contract specifies a runtime environment for web components that includes security, concurrency, life-cycle management, transaction, deployment, and other services. A web container provides the same services as a JSP container as well as a federated view of the Java EE (formerly J2EE) platform APIs.
Examples of web containers are: Sun Java System Application Server Sun Java System Web Server Tomcat for Java WSDP and The term web server can mean one of two things: A computer program that is responsible for accepting HTTP requests from clients (user agents such as web browsers), and serving them HTTP responses along with optional data contents, which usually are web pages such as HTML documents and linked objects (images, etc.). A computer that runs a computer program as described above On 2/9/09, Pravin Sinha <pks_chen...@yahoo.com> wrote: > Nachiket, > > Both are different.
