Introduction Ito Weblogic 10.3

Oracle BEA Weblogic 10.3:

Oracle BEA Weblogic platform is a unified, simplified, and extensible platform

for building, extending, integrating, deploying, and managing applications. Weblogicplatform includes a rich development and deployment framework for integrating

valuable resources and tools into your environment third!party applicationpackages, custom applications, messaging systems, web services, trading partners,

and more.

In"tallation:

While installing Web"ogic #$.% package, include workshop for weblogic along

with weblogic server.

Workshop for weblogic is a set of plug!ins to the Eclipse '(E platform that

allows you to )uickly and easily create enterprise applications *+OA, -EE fordeployment on a wide variety of servers, including Web"ogic +erver, /omcat, Boss,

and others.

What is a (omain and why we are creating (omain in weblogic server7

TCS Confidential


9/30

(omain is logical grouping of resources and services and consists

of Administration +erver, 8anaged +erver and cluster. /here can only be one

administration +erver in domain and 5ero to 9 8anaged +erver.

A domain is the basic administration unit for Web"ogic +erver instances. A

domain consists of one or more Web"ogic +erver instances *and their associatedresources that you manage with a single Administration +erver. :ou can define

multiple domains based on different system administrators; responsibilities,application boundaries, or geographical locations of servers. 3onversely, you can use

a single domain to centrali5e all Web"ogic +erver administration activities.

Each domain;s configuration is stored in a separate configuration file called

config.xml, which is stored on the Administration +erver along with other files suchas logs and security files. When you use the Administration +erver to perform a

configuration task, the changes you make apply only to the domain managed by thatAdministration +erver. /o manage another domain, use the Administration +erver for

that domain. 0or this reason, the servers instances, applications, and resources inone domain should be treated as being independent of servers, applications, and

resources in a different domain.:ou cannot perform configuration or deploymenttasks in multiple domains at the same time.

'!pe" o# "er%er":

Administration +erver ! A domain always includes one Web"ogic +erver instance thatis configured as an Administration +erver. /he Administration +erver provides a

central point from which to manage the domain, and it provides access to Web"ogic+erver administration tools.

8anaged +ervers ! All other Web"ogic +erver instances in a domain are called

8anaged +ervers.8anaged +ervers host the application components and resources,which are also deployed and managed as part of the domain.

3lusters ! A domain may also include Web"ogic +erver clusters, which are groups of

Web"ogic

+erver instances that work together to provide scalability and high availability for

applications. 3lusters can improve performance and provide failover should a server

instance becomes unavailable.

&tep" in%ol%ed in deplo!ing a ()EE application:

/he purpose of this document is to explain the deployment of a -EE

application in Weblogic server #$.%. 'n our sample application user will submit a

re)uest at front end and the re)uired information is fetched from (B and displayed ina report format.

Our sample -EE application includes a web module and EB module.

Basically web module will have the source files re)uired by the presentation layer

and EB module will have different types of e


17/30

An EB module is used to assemble one or more enterprise beans into a singledeployable unit. An EB module is stored in a standard ava archive *A1 file.

An EB module contains the following

One or more deployable enterprise beans.

A deployment descriptor, stored in an Extensible 8arkup "anguage *>8" file./his file declares the contents of the module, defines the structure and

external dependencies of the beans in the module, and describes how thebeans are to be used at run time.

We can deploy an EB module as a stand alone application, or combine it with otherEB modules or with Web modules to create a -EE application. An EB module is

installed and run in an enterprise bean container.

3reate an EB in weblogic workshop '(E as below
