ANT Deployment

Hi Guys

This post is information about the Ant Deployment

ant  - Another Neat Tool

ant – is  a build and deploy tool that is used to create and deploy archive files.

Welogic internally provides an ant task “wldeploy” that can be used in ant scripts to automate deployment.

This wldeploy internally calls weblogic.Deployer

ant deployment depends on the configuration file called build.xml

the structure of build.xml file

Project  -à

            Properties  -- > Each property has a name & a value for that property.

            These properties can be defined as per the requirements and values need to assigned.

            taskdef  à the ant task “wldeploy” classfile will be defined in the build.xml file

            targets à targets are blocks of code that take certain action. For Eg. Deploy

Build.xml file sample:

<project name="webservices-hello_world" default="deploy">

<property name="wls.username" value="wlsadmin" />

<property name="wls.password" value="wlsadmin" />

<property name="wls.hostname" value="192.168.128.9" />

<property name="wls.port" value="20001" />

<property name="admin.server.name" value="Admin" />

<property name="deploy.target" value="softCluster1" />

<!-- Here you can specify Either ClusterName, IndividualServerName Like "ManagedOne" or comma Seperated List of Managed/AdminServer -->

<property name="deploy.name" value="jsf" />

<property name="deploy.source" value="deploy/jsf-1.2.war" />

<!-- Setting TaskDefinition -->

<taskdef name="wldeploy" classname="weblogic.ant.taskdefs.management.WLDeploy">

<classpath>

<pathelement location="/home/durgasoft/bea10.3.0/wlserver_10.0/server/lib/weblogic.jar"/>

</classpath>

</taskdef>

<!-- Deploying Applications  -->

<target name="deploy">

<wldeploy action="deploy"

          name="${deploy.name}"

          source="${deploy.source}"

          user="${wls.username}"

          nostage="true"

          password="${wls.password}"

          verbose="true"

              library="true"

          adminurl="t3://${wls.hostname}:${wls.port}" targets="${deploy.target}" />

</target>

<!-- Redeploying Applications  -->

<target name="redeploy">

<wldeploy action="redeploy"

          name="${deploy.name}"

          user="${wls.username}"

          password="${wls.password}"

          verbose="true"

          adminurl="t3://${wls.hostname}:${wls.port}" targets="${deploy.target}" />

</target>

<!-- Uneploying Applications  -->

<target name="undeploy">

<wldeploy action="undeploy"

          name="${deploy.name}"

          failonerror="false"

          user="${wls.username}"

          password="${wls.password}"

          verbose="true"

          adminurl="t3://${wls.hostname}:${wls.port}" targets="${deploy.target}" />

            </target>

            </project>

After the build file is configured properly, the individual targets can be invoked.

Invoking the ant targets:

1)      ant  ( with out any arguments , will invoke the default target on the first line of build.xml)

2)      ant deploy  -- will invoke the “deploy” task

3)      ant undeploy  -- will invoke the “undeploy” task

4)      ant redeploy   -- will invoke the “redeploy “ task

if you have to invoke the ant deploy with a different configuration file , other than build.xml , then

            ant –f <config-file-name> b.xml
