Difference between AppServer and a Web server (1) Webserver serves pages for viewing in web browser, application server provides exposes businness logic for client applications through various protocols. (2) Webserver exclusively handles http requests.application server serves bussiness logic to application programs through any number of protocols. (3) Webserver delegation model is fairly simple,when the request comes into the webserver,it simply passes the request to the program best able to handle it(Server side program). It may not support transactions and database connection pooling. (4) Application server is more capable of dynamic behaviour than webserver. We can also configure application server to work as a webserver.Simply applic! ation server is a superset of webserver.

In our current project we are working on RAD migration from 6.x.x RAD 7.5.4. As part of migration we have to enable security settings in Websphere application server for the deployed application. We have enabled it and given proper credentials and configured other required settings and properties in the WAS. We started the server, but we have found the error in sustemOut.log the following error.
