1. Setup Unix environments (user/group ids, filesystems, tools, access - sudo, etc.)
2. Install WebLogic, JDK, Web Application Development Tools (ant, XML editors EditiX)
3. If production requires middle tier High Availability, setup Veritas VCS application agent monitoring java process and filesystems. I posted a Weblogic HA setup procedure in 2002 at THIS SITE.
4. Setup Web Application Containers in Weblogic environment
Weblogic Admin port 7001

Terms:
Web Application Container normally in a WAR file - contains an application's resources such as:
a. servlets (java class)
b. JavaServer Pages (JSPs)
c. JSP tag libraries
d. any static resources such as html pages, image files etc.
Servlets - java class, HTTP Servlet - html inside Java
JSP - JavaServer Pages - java inside html
Weblogic provides J2EE (Java Enterprise Environment) environment and services/APIs to web application containers, this services include EJBs,
database connections (JDBC), Java Messaging Sevice (JMS), XML and more.
Servlets
A servlet is a Java class that runs in a Java-enabled server. An HTTP servlet is a special type of servlet that handles an HTTP request and provides an HTTP response, usually in the form of an HTML page. The most common use of WebLogic HTTP Servlets is to create interactive applications using standard Web browsers for the client-side presentation while WebLogic Server handles the business logic as a server-side process. WebLogic HTTP servlets can access databases, Enterprise JavaBeans, messaging APIs, HTTP sessions, and other facilities of WebLogic Server.
WAR files
Web Archive Files - A WAR file contains
a. one servlet/one JSP along with helper classes,
b. a weblogic.xml deployment descriptor, an XML document containing Weblogic Server specific elements for web applcations
c. optional web.xml deployment descriptor, XML file describes the contents of the war file
d. any static html pages/image files
The WAR file can be deployed alone or packaged in an Enterprise application archive (EAR file) with other application components. If deployed alone,
the archive must end with a .war extension. If deployed in an EAR file, the archive must end with an .ear extension.
Oracle recommends that you package and deploy your stand-alone Web applications as part of an Enterprise application. This is an Oracle best practice,
which allows for easier application migration, additions, and changes. Also, packaging your applications as part of an Enterprise application allows
you to take advantage of the split development directory structure, which provides a number of benefits over the traditional single directory structure.
EAR file (Enterprise Application Archive) .ear file, the .WAR file can be deployed alone or packaged in an EAR file.
JSPs and HTTP servlets can access all services and APIs available in WebLogic Server. These services include EJBs, database connections by way of
Java Database Connectivity (JDBC), Java Messaging Service (JMS), XML, and more.
