Use the Apache Ant tool to create these files. Apache Ant is a Java-based build tool that enables you to generate XML-based configurations files as follows:
<?xml version="1.0" encoding="ISO-8859-1"?>
<project default="build">
<dirname property="basedir" file="${ant.file}"/>
<property name="beanname" value="SimpleBean"/>
<property name="jarfile" value="${basedir}/${beanname}.jar"/>
<target name="build" depends="compile">
<jar destfile="${jarfile}" basedir="${basedir}" includes="*.class">
<manifest>
<section name="${beanname}.class">
<attribute name="Java-Bean" value="true"/>
</section>
</manifest>
</jar>
</target>
<target name="compile">
<javac destdir="${basedir}">
<src location="${basedir}"/>
</javac>
</target>
<target name="clean">
<delete file="${jarfile}">
<fileset dir="${basedir}" includes="*.class"/>
</delete>
</target>
</project>
