一．在jboss启动时加载class方法
A． 编写class，要import org.jboss.varia.scheduler.Schedulable包，此包在%JBOSS_DISC%\server\all\lib目录下，同时要把编译好的class(压成包)放在%JBOSS_DISC%\server\all\lib目录下，以便能加载。
B．修改%JBOSS_DISC%/server/all/conf/jboss-service.xml文件
添加以下相似文字：
<!--============================================================ -->
<!-- Scheduler Initialization 定时操作 -->
<!--============================================================ -->
<mbean code="org.jboss.varia.scheduler.Scheduler"
name="jboss. piosan.util:service=Scheduler">
<attribute name="StartAtStartup">true</attribute>
<attribute name="SchedulableClass">com.piosan.util.PiosanTimer</attribute>
<attribute name="SchedulableArguments">TheName,123456789</attribute>
<attribute name="SchedulableArgumentTypes">java.lang.String,long</attribute>
<attribute name="InitialStartDate">NOW</attribute>
<attribute name="SchedulePeriod">1000</attribute>
<attribute name="InitialRepetitions">-1</attribute>
</mbean>
<!—name为任意但唯一，com.piosan.util.PiosanTimer为class名 -->
<!—SchedulableArguments的值为传递参数,这里为两个参数,theName为String型，123456789为long型,在SchedulableArgumentTypes中体现了 -->
<!—SchedulePeriod 的值为每隔1秒操作一次 -->
C． 附上PiosanTimer.java源代码例子
