Completing an EAR

Completing an EAR
(Page 1 of 4 )

Ant EAR task

The final step in the process is to EAR up the results of the webapp and common builds. Just as there is a WAR task, Ant also provides us with an EAR task, as in Example 3-4.

Example 3-4.  master build.xml

<target name="ear" depends="compile">
        <ear destFile="${distribution.dir}/${ear.name}"
             appxml="${meta-inf.dir}/application.xml" >

            <!-- files to be included in
/ -->
            <fileset dir="${webapp.war.dir}" />
            <fileset dir="${common.jar.dir}" />
        </ear>
    </target>

Notice that the EAR task requires us to pass it a well-formed application.xml file. Example 3-5 shows what a simple one looks like.

Example 3-5.  application.xml

<?xml version="1.0" encoding="UTF-8"?>
<application xmlns=http://java.sun.com/xml/ns/j2ee 
           xmlns:xsi=http://www.w3.org/ 2001/XMLSchema-instance 
           xsi:schemaLocation="http:// java.sun.com/xml/ns/j2ee
               http://java.sun.com/
xml/ns/j2ee/application_1_4.xsd"
           version="1.4">
  <display-name>JBossAtWorkEAR</display-name>

  <module>
      <web>
         <web-uri>webapp.war</web-uri>
         <context-root>jaw</context-root>
      </web>
  </module>

  <module>
      <java>common.jar</java>
  </module>

</application>

To verify the results of themasterbuild, change to the build/distribution directory and typejar tvf jaw.ear. You should see webapp.war, common.jar, and application.xml. We are now ready to deploy the EAR file.
