Java J2EE
Java 2 Platform Enterprise Edition is a traditional Java platform that well designed and developed for the mainframe scale processing typical of large scale businesses. J2EE composed of many different APIs that is used to develop enterprise applications.
In this PDF, we explain the J2EE components, How to start J2EE, How to run a J2EE, Server & deployment tool, Services and Protocols of J2EE, Process step cycle, Standards and Specifications of J2EE.
Java J2EE
J2EE Components Here, J2EE specification defines the some J2EE components: ●
Application clients and applets are elements that run on the client.
●
Java Servlet and JSP technology components are Web components that run on the server.
●
EJB components are business components that run on the server.
●
JSP and Servlet technology elements are Web elements that run on the server.

Test the installation
How To Run J2EE Server & Deployment Tool To start the J2EE server, open up command window & type the following code: set JAVA_HOME=c:\j2sdk1.4.1 set J2EE_HOME=c:\j2sdkee1.3.1 cd %J2EE_HOME%\bin j2ee -verbose
To run the deployment tool, open up another command window and & the following: set JAVA_HOME=c:\j2sdk1.4.1 set J2EE_HOME=c:\j2sdkee1.3.1 cd %J2EE_HOME%\bin deploytool

Standards & Specifications Of Java J2ee
J2EE contains several API requirements (JMS, RMI, Web Solutions, E-Mail, XML, etc.) and it how to organize them. Java J2EE development components such as Servlets, Java Beans, JavaServer Page, etc. These are J2EE components that use to create enterprise applications and these applications are convenient, scalable, and that incorporate with heritage technologies. A J2EE application server works with security, concurrency, transactions, scalability and control of the components.
