Weblogic Learning Part1

Difference between webserver and Application Server

1)Web server only provides env to run web application
but
Application Server provide env to run both Web App and Enterprise App.

2)Web server only provides support for web related technologies
but
Application server provide support for any technology from Java J2EE
3)Webserver Example

Application Server
====================
Websphere,JBOSS,Weblogic,Glassfish,wildfly etc.

4)Web server —->only has —->web container
Application Server —>has —>web container + ejb container

Types of Java Application

1)Standalone Application
2)Enterprise Application
a)Web Application
b)Distributed Application

Client Server Architecture

[MVC]

Controller: Accept the upcoming req from the. [eg:Servlet]

Model : It has business Logic. [eg: JDBC/Ejbs/Hibernet/Spring etc]

View: Give the result to client.[eg: JSPs]

Why Weblogic

1)We can use SOA,OBIEE,OIM/OAM,EBS12,OEM13c etc. with weblogic
2)In 12c we can create multiple tenants/partitions in one domain
3)Weblogic 12c we can also run over Docker Conatiners,Private Clouds, Public clouds etc.
4)can easily create and maintain multiple domain
5)Power-full clustering methodology to balance the load on server instance.
6)Most things are OOBX so very less configurations are required.
7)Very stable and resilient [ie.. can easily be recovered]
8)Easy to configure access level using security relams.
