creating stubs using the wsdl that is provided using ant script

[ramu somu]

Can some one help me to create stubs in the form of jar file using the wsdl that I am provided

[ramu somu]

<target name="planDetails">
			<taskdef name="wsdl2java" classname="org.apache.axis.tools.ant.wsdl.Wsdl2javaAntTask" loaderref="axis">
				<classpath refid="compile.classpath" />
			</taskdef>
			<echo>wsdl2java_package is: com.wsdl2java.formgenerator</echo>
			<delete dir="${BASE}/build/wsld2java/PlanDetails"/>
			<mkdir dir="${BASE}/build/wsld2java/PlanDetails"/>
			<wsdl2java url="http://......../planDetails?wsdl" output="${BASE}/build/wsld2java/PlanDetails" testcase="false" verbose="no">
				<mapping namespace="http://......../planDetails" package="com.wsdl2java.planDetails" />
			</wsdl2java>
			<javac srcdir="${BASE}/build/wsld2java/planDetails" destdir="${BASE}/build/wsld2java/planDetails" debug="${javac.debug}">
				<classpath refid="project.class.path" />
			</javac>
			<delete file="${BASE}/lib/planDetails.jar" />
			<jar jarfile="${BASE}/lib/planDetails.jar" basedir="${BASE}/build/wsld2java/planDetails">
			</jar>
		</target>

For this I am getting below error

java.lang.NoSuchMethodError: org.apache.axis.enum.Scope.getScope(Ljava/lang/String;Lorg/apache/axis/enum/Scope;)Lorg/apache/axis/enum/Scope;

Please help me out
