Oracle's WebLogic 11g Server is an application server for building and deploying enterprise Java EE applications. WebLogic's infrastructure supports the deployment of many types of distributed applications and is an ideal foundation for building applications based on a Service Oriented Architecture. This book will guide you through the important administration aspects of WebLogic Server.
This book will teach administrators the techniques for installing and configuring Oracle WebLogic Server and how to deploy Java EE applications using the Administration Console, command-line interface, and scripting tools such as WLST. This book starts with a good overview of the needed techniques in the middleware world of today. Clear explanations of definitions and concepts of JEE and how Oracle WebLogic fits into that are also provided. The book then dives into performing routine Oracle WebLogic Server administration functions, and how to deploy different types of Java EE applications to WebLogic Server.

In this book, you will find a number of styles of text that distinguish between different kinds of information. Here are some examples of these styles, and an explanation of their meaning.
Code words in text are shown as follows: "JVMs trigger java.lang.OutOfMemoryError when there is insufficient memory to perform some task".
A block of code is set as follows:
connect("username","password")
edit()
startEdit()
cmo.setConsoleEnabled(true)
save()Any command-line input or output is written as follows:
unpack-template=path_of_jar_file-domain=path_of_domain_to_be_created [-user_name=username] [-password=password] [-app_dir=application_directory] [-java_home=java_home_directory] [-server_start_mode=dev|prod] [-log=log_file] [-log_priority=log_priority]New terms and important words are shown in bold. Words that you see on the screen, in menus or dialog boxes for example, appear in the text like this: "The SSL tab for the specified Server Instance is used to configure the BEA Hostname Verifier".
