config file

 <!-- spring's scheduling support --> <task:scheduled-tasks scheduler="taskscheduler">    <task:scheduled ref="scheduleservice" method="performservice" fixed-delay="2000"/> </task:scheduled-tasks>  <!-- bean actual work --> <bean id="scheduleservice" class="com.ctbllc.ctb.scheduling.scheduleservice" />  <!-- defines threadpooltaskscheduler instance configurable pool size. --> <task:scheduler id="taskscheduler" pool-size="1"/>
