I have a spring class with main method. Inside the class am trying to read the values applicationContext.xml . My intention is to jar this main class along with its dependant jars,property files and applicationContext.xml .Hence i have my target as below

 <target name="testing" depends="init">
<property name="mech.dir" value="${target.dir}/MECHNSM" />
<property name="mech.classes.dir" value="${mech.dir}/classes" />
<delete dir="${mech.dir}" />
<mkdir dir="${mech.dir}" />
<mkdir dir="${mech.classes.dir}" />
<copy file="${tests.dir}/Mechanism.properties"      todir="${mech.classes.dir}" overwrite="true" />
<copy file="${tests.dir}/applicationContext.xml" todir="${mech.classes.dir}" overwrite="true" />
<javac destdir="${mech.classes.dir}" debug="true" classpath="/jars/dependency_jars/spring-context-support-3.1.1.RELEASE.jar" classpathref="project.class.path">
    <src path="${tests.dir}"/>
    <include name="com/test/Sample.java" />
</javac>
<jar destfile="${retymech.dir}/retryOrderPerformPost.jar" basedir="${retymech.classes.dir}">
    <manifest>
        <attribute name="Main-Class" value="com.test.Sample"/>
    </manifest>
    <!--<zipgroupfileset dir="${lib.dir}" includes="**/*.jar" />-->
    <zipfileset src="${lib.dir}/spring-web-3.1.1.RELEASE.jar" includes="**/*.class" excludes="META-INF/**/*" />

While executing the jar file using java -jar command it is throwing me the below exception

Exception in thread "main" org.springframework.beans.factory.parsing.BeanDefinit ionParsingException: Configuration problem: Unable to locate Spring NamespaceHandler for XML schema namespace [http.springframework.org/schema/context]
