Your question implies that you have written code that you expect to generate a WAR, but you have no instruction to do so. I see from your comment you are actually asking what the command should be.
Most important: I hope we are all new to things, after 35 years in the industry I learn something every day. Why did you ask the question rather than google? Learning to search is the most important skill. Google ant task WAR gives this task with an example:
<war destfile="myapp.war" webxml="src/metadata/myapp.xml">
<fileset dir="src/html/myapp"/>
<fileset dir="src/jsp/myapp"/>
<lib dir="thirdparty/libs">
<exclude name="jdbc1.jar"/>
</lib>
<classes dir="build/main"/>
<zipfileset dir="src/graphics/images/gifs"
prefix="images"/>
</war>
and a similar entry for EAR:
<ear destfile="${build.dir}/myapp.ear" appxml="${src.dir}/metadata/application.xml">
<fileset dir="${build.dir}" includes="*.jar,*.war"/>
</ear>
