1. Create Synchronouse Sample
add  <bpws:variable name="Variable1" type="xsd:boolean"/>
and change sequence to
    <sequence>
        <receive name="start" partnerLink="SynchronousSample"
operation="operation1" portType="ns1:portType1" variable="inputVar"
createInstance="yes"/>
        <bpws:assign name="Assign1">
            <bpws:copy>
           
<bpws:from>$inputVar.inputType/paramA</bpws:from><bpws:to>$outputVar.resultType/paramA</bpws:to>
            </bpws:copy>
            <bpws:copy>
                <bpws:from>true()</bpws:from>
                <bpws:to variable="Variable1"/>
            </bpws:copy>
        </bpws:assign>
        <bpws:while name="While1">
            <bpws:condition>$Variable1</bpws:condition>
