Deploying and testing Stateless Session Bean
In this EJB tutorial we will build, deploy and
test the Stateles Session Bean developed in the last section. We will use ant
build tool to build ear file. We will deploy our application using WebLogic
console.
Building ear file using ant build tool
I am assuming that you have ant build tool installed on
your development environment. Download the source code from here
and extract in your favorite directory. Open command prompt and navigate
to the directory <extracted directory>/sessionbean/code and type
ant there. Ant build tool will compile, package and create example.ear in
the <extracted directory>/sessionbean directory. Here is the
code of our ant build file:.
<?xml version="1.0"?>
<project name="WebLogic Tutorials" default="all" basedir=".">
<target name="init">
<!-- Define -->
<property name="dirs.base" value="${basedir}"/>
<property name="classdir" value="${dirs.base}/build/classes"/>

<property name="deploymentdescription" value="${dirs.base}/deploymentdescriptors"/>
<property name="warFile" value="example.war"/>
<property name="earFile" value="example.ear"/>
<property name="jarFile" value="example.jar"/>
<property name="earDir" value="${dirs.base}/build/ear"/>
<property name="warDir" value="${dirs.base}/build/war"/>
<property name="jarDir" value="${dirs.base}/build/jar"/>

</copy>
<!-- Create jar file and place in ear directory -->
<jar jarfile="${earDir}/${jarFile}" basedir="${jarDir}" />
</target>
<!-- Create the ear File -->
<target name="buildEar" depends="init">

</copy>
<!-- Create ear file and place in ear directory -->

</target>
</project>

Deploying the Application on Web Logic 6.0 Server
Run the WebLogic default server:
To deploy the application we will use WebLogic console.
Type http://localhost:7001/console
and enter user name and password to open the WebLogic console.
Navigate to "Applications" and then click on
"Install a new Application", following screen will be displayed:
Browse "example.ear" and then click on the
Upload button. This will upload the file to the WebLogic server directory and
then install the application.
Testing the application
To test the application open browser and type http://localhost:7001/example/index.jsp,
following page should be displayed:
Click on the link "Call Session Test Servlet",
it should show you the following output:
check the WebLogic server dos console, it should be displaying the message
"Hello! I am Session Bean" as show below in the screen shot:
In this lesson we learnt how to deploy Session Bean and
test on Web Logic Server.
